Carrier-bursting is an attractive RF transmitter concept to achieve high efficiency. The power amplifier (PA) itself either operates at its peak efficiency or is turned off. Another efficiency-enhancing approach is the Doherty concept, where the main PA reaches its peak efficiency already in back-off and the peak PA contributes at high input levels to reach the desired output power. In this work,
Inside-out inner mitochondrial membranes free of matrix proteins were isolated from purified potato tuber (Solanum tuberosum L.) mitochondria and incubated with [γ-32P]ATP. Proteins were separated by SDS-PAGE and visualized by autoradiography. Phosphorylation of inner membrane proteins, including ATPase subunits, was strongly inhibited by the phosphoprotein phosphatase inhibitor NaF. We propose th
A feasibility study is presented and the achieved key design milestones towards the first application of Chemical Species Tomography by Near-IR Absorption Tomography on a heavy duty, large-bore marine engine to visualise relative mixture strength are described. The engine is equipped with pre-chamber ignition and operates using Liquefied Natural Gas with >88.9% methane content. Operation of the en
At the beamline D7 at the MAX III ring at the MAX IV laboratory we have a setup for infrared microspectroscopy which is usable from 30 to 10000 cm-1. In this project specular reflection infrared microspectroscopy was used for chemical imaging of cross-sectioned urinary stones. to determine their chemical composition and morphology simultaneously. Absorption spectral bands were recovered from refle
The need for developing highly efficient solar cell devices have never been so pressing until recently when the urgency of using renewable energy sources becomes more evident. There are several promising technologies being explored by many groups with the sole purpose of optimizing harvesting sunlight and converting it to useful electricity. These include, but not limited to, dye- and quantum dot-
An important aspect of higher education is to educate students who can manage complex relationships and solve complex problems. Teachers need to be able to evaluate course content with regard to complexity, as well as evaluate students’ ability to assimilate complex content and express it in the form of a learning outcome. One model for evaluating complexity is the Structure of Observed Learning O
Direct conversion receivers are widely used for full duplex mobile radio communication systems. This paper describes a novel SAW-less single-ended RF amplifier connected to a single-ended mixer with a feedback loop that suppresses the second-order distortion from TX cross modulation of the LO-leakage as well as DC-offset at the mixer output. In Monte Carlo simulations the design achieves +47 dBm m
Avhandlingens ämne är osannolika händelser i den realistiska romanen. Den övergripande idén är att realismen utmärks av att osannolika händelser hanteras utifrån ett dubbelt perspektiv: både som ett existentiellt och ett estetiskt bekymmer. Som ett existentiellt bekymmer representerar den narrativa fiktionsberättelsens osannolika händelser den ständigt närvarande möjligheten att en oförutsägbar ocThis thesis deals with improbable events in the realistic novel. The overarchingidea is that realism is distinguished by dealing with improbable events on thebasis of a double perspective: both as an existential and as an aesthetic problem.As an existential problem the improbable events of narrative fiction representthe constantly present possibility of an unexpected and unforeseen event suddenly
The objective of this study was to investigate the influence of native milk fat globule size on the aeration of high fat dairy products with regard to maximum firmness time, gas inclusion and foam stability. The results showed that whipping time to maximum firmness was inversely proportional to mean fat globule size for both unhomogenised and slightly homogenised (2 MPa) creams. Additionally, incr
Type 2 diabetes (T2D) is a global pandemic. Genome-wide association studies (GWASs) have identified >100 genetic variants associated with the disease, including a common variant in the melatonin receptor 1 b gene (MTNR1B). Here, we demonstrate increased MTNR1B expression in human islets from risk G-allele carriers, which likely leads to a reduction in insulin release, increasing T2D risk. Accordin
En diskussion av filmmusikkompositören Bernard Herrmanns musik. Herrmann, som är mest känd för sitt samarbete med Orson Welles och Alfred Hitchcock, skapade en musik som mer än andra kompositörer satte sin unika prägel på de projekt han var involverad i. Texten diskuterar hans sätt a skapa ett samspel mellan ljud och bild genom att bryta upp musikens ledmotiv i mindre, kortare, fraser, för att på
Texten är en diskussion av kompositionella aspekter på film med centralperspektivet som utgångspunkt. Detta jämförs med parallellperspektivet som kom till Europa från framförallt Japan och kom att utgöra ett dominerande inflytande på den europeiska modernismen inom måleriet. Vid sidan om rent kompositionella aspekter diskuteras i texten zoom estetiken och den ursprungligen oavsiktliga perspektivfö
Molecularly imprinted polymers (MIPs) have been developed mostly for the specific binding of the target, mimicking the function of antibodies. In addition to these " plastic antibodies," completely synthetic catalysts have been created that mimic substrate conversion by enzymes. In this chapter, the following examples will be presented: (1) an esterolytic MIP for phenolic esters that is prepared u
