This paper presents a technique to reduce the noise figure of a passive mixer-first receiver front-end. By using lower than 50Ω switch resistance in the current-mode passive mixer and introducing a positive feedback from baseband to the RF-input, it can be well matched close to fLO while achieving a noise figure below 3dB, which is otherwise a fundamental limit. A quadrature front-end prototype fo

Whether or not communities of microbial eukaryotes are structured in the same way as bacteria is a general and poorly explored question in ecology. Here, we investigated this question in a set of planktonic lake microbiotas in Eastern Antarctica that represent a natural community ecology experiment. Most of the analysed lakes emerged from the sea during the last 6000 years, giving rise to waterbod

In the intestinal tract, there are enzymes that hydrolyze both endogenous and exogenous sphingolipids. The alkaline sphingomyelinases (SMase) of the gut and human bile have been most studied, and a major part of this chapter discusses these enzymes. It also discusses studies of ceramidase, glycosylceramidase, and the digestion of dietary sphingolipids. In the intestinal tract, a distinct enzyme th

This project is designed as a typical consultancy work for Environmental Engineering students at the Faculty of Engineering (LTH), Lund University, Sweden. It gives students a feeling of a possible future work by being a practical training in solving a complex environmental problem involving hydrological and ecological challenges. Additionally, the project work provides training of critical thinki

From newly obtained high-resolution, high signal-to-noise ratio spectra the abundances of the elements La and Eu have been determined over the stellar metallicity range -3<[Fe/H]<+0.3 in 159 giant and dwarf stars. Lanthanum is predominantly made by the s-process in the solar system, while Eu owes most of its solar system abundance to the r-process. The changing ratio of these elements in stars ove

In this paper we explore the potential of cross-fertilization between research on welfare state reforms and on efforts to green the state in response to ecological challenges. In order to gain a deeper understanding of the conditions for an ecological state to emerge we relate welfare state studies to green political theory, that provide different conceptions of the ecological state and ways to gr

Deep cuts in carbon emissions to avoid dangerous climatic change will require fundamental transformations of the energy and transport systems. This is an enormous challenge for society and the political system. In order to tackle this challenge, we argue that it will be necessary to develop new institutions and institutional practices that address and give priority to long-term climate policy obje

In the context of future climate change, the flush of CO2 emissions from soils after drying-rewetting events could have a strong impact on the terrestrial carbon balance. Mixed forests may be more resistant and resilient to drought events compared to monocultures, and as such may modulate the effects of drought on soil functioning belowground. We investigated the influence of mixed planting and dr

Tramways are a sustainable and accessible mode for public transport. They promote urban development and contribute to a more attractive city. Light rail, but also public transport as a whole, is an important part of society as it is accessible to everyone and reduces the amount of cars needed. The two tramlines in Norrköping account for two thirds of public transport travel in the city. The purpos

We have reviewed 184 patients after repair of primary hypospadias. They were operated on and followed-up according to a standard protocol, and the senior author (HS) participated in all operations. The patients were reconstructed using a Byars two-stage procedure ( n = 102) or a Scuderi ( n = 29) or Mathieu ( n = 41) single-stage procedure. The rest ( n = 12) just had a removal of the chordee with

A total of six high-resolution FT-IR spectra for trans-glyoxal-d(2), trans-glyoxal-d(1) and trans-glyoxal-C-13(2) were recorded with a resolution ranging from 0.003 to 0.004 cm(-1). By means of a simultaneous ground state combination difference analysis for each of these isotopologues using the Watson Hamiltonian in A-reduction and I-r-representation the ground state rotational constants are obtai

The Na-33 beta decay was studied online using mass separation techniques and a first description of the level structure of the neutron-rich isotope Mg-33, with N=21, has been obtained. The experiment involved the measurement of beta-gamma, beta-gamma-gamma, and beta -n-gamma coincidences as well as neutron spectra by time-of-flight technique. The first low energy level scheme for the daughter nucl
