This paper presents a front-end architecture for fully integrated 60 GHz phased array receivers. It employs LO-path beamforming using a phase controlled phase-locked loop (PC-PLL). To demonstrate the architecture a circuit is implemented featuring a two stage low noise amplifier, two cascaded active mixers, and a PC-PLL. The receiver downconverts the 60 GHz signal in two steps, using LO signals fr
The calcium-sensitizing Rho A/Rho kinase pathway has been suggested to play a role in the control of nongenital vascular smooth muscle. Rho-associated kinases (ROKs) cause calcium-independent modulation of smooth muscle contraction, and have been demonstrated in the bladder, prostate, and corpus cavernosum. Until now, it is not known whether ROKs and related proteins play a role in the control of
We have developed the novel Aerosol Dynamics, gas- and particle-phase chemistry model for laboratory CHAMber studies (ADCHAM). The model combines the detailed gas-phase Master Chemical Mechanism version 3.2 (MCMv3.2), an aerosol dynamics and particle-phase chemistry module (which considers acid-catalysed oligomerization, heterogeneous oxidation reactions in the particle phase and non-ideal interac
The partly hot-water driven CO2 capture plant offers a significant potential for improvement in performance when implemented in a combined-cycle power plant (CCPP). It is possible to achieve the same performance with a dual-pressure steam cycle as in a triple-pressure unit. Even a single-pressure plant can attain an efficiency competitive with that achievable with a triple-pressure plant without t
Background: Research involving expressed sequence tags ( ESTs) is intricately coupled to the existence of large, well-annotated sequence repositories. Comparatively complete and satisfactory annotated public sequence libraries are, however, available only for a limited range of organisms, rendering the absence of sequences and gene structure information a tangible problem for those working with ta
Popular Abstract in Swedish Kroppens immunförsvar, vars uppgift är att skydda oss mot infektioner, består av ett antal olika celltyper som till stor del finns i blodet. Immunförsvaret kan indelas i två delar; ett medfött försvar som är likadant hos alla individer och ett försvar som byggs upp under individens livstid. Det senare utformas olika beroende på vilka bakterier och virus som individen utThe cells of the innate immune system are essential for the host's first line defence against infection. Among these cells the neutrophil granulocyte has a central role by the production of antibiotic proteins and peptides. These are targeted for storage in secretory lysosomes and other neutrophil granules for subsequent release by regulated secretion in an inflammatory process. However, the granu
In a warming climate, permafrost is likely to be significantly reduced and eventually disappear from the sub-Arctic region. This will affect people at a range of scales, from locally by slumping of buildings and roads to globally as melting of permafrost will most likely increase the emissions of the powerful greenhouse gas methane, which will further enhance global warming. In order to predict fu
The objective of this thesis is to propose a way to introduce social and cultural aspects of environmental degradation to the sustainable development debate. This is done by a reflexive and critical examination of environmental research as it has been applied to different spatial levels (and thus levels of social complexity). The spatial categories discussed are the city, the household and the lan
Dödsstraffet är ett straff som har diskuterats i hundratals år. Jag är själv fascinerad av de argument som har använts, och fortfarande används, för och emot bibehållandet av strafftypen. Genom att studera förarbeten och doktrin har jag försökt utreda hur och varför Sverige avskaffade dödsstraffet. Jag har också jämfört den svenska processen med den som pågick vid ungefär samma tid i Danmark. BådaThe death penalty has been debated for hundreds of years. I am personally fascinated by the arguments used for keeping and removing the penalty from the legislation. I have by studying the legislative history and doctrine tried to research how and why Sweden abolished the death penalty. I also compared the results with the same process in Denmark. Both countries chose to abolish the death penalty
Den här uppsatsen kretsar kring svenska kommuners drift av gym, en företeelse som gör att kommunen agerar som aktör på den öppna marknaden. I takt med att allt mer av den offentliga och den privata sektorn har smält samman så har också antalet konkurrenskonflikter som detta kan föranleda ökat. Det privata näringslivet har under årtionden påtalat att de upplever det som ett problem och att den offeThis essay revolves around Swedish municipalities' operation of gyms, a phenomenon that makes the municipalities act as players on the open market. As more and more of the public and private sectors have merged the number of competitive conflicts that this has caused has also increased. The private sector has, for decades, complained that it feels it is an issue and that the public sector is n
Cardiac magnetic resonance (CMR) images are used to investigate the heart for medical and research purposes. By injecting a contrast substance into the patient, myocardial infarctions (heart attacks) can be visualized in CMR image sets consisting of a number of image slices at different levels of the heart. Analysis of these images can detect an infarction, delineate it and estimate its size. This
We present an extensive rheology study of the wormlike micelle system lecithin-water-cyclohexane. In this system the micelles are really wormlike, meaning that there are no signs of micellar branching, as it has previously been demonstrated by NMR self-diffusion experiments (R. Angelico, U. Olsson, G. Palazzo and A. Ceglie, Phys. Rev. Lett., 1998, 81, 2823). Wormlike micelles break and recombine,

?SEPARATE WORLDS?. School librarians teaching in information seeking in high school. The aim of this Master's thesis is to study how information seeking is taught in high school and how school librarians describe their experiences of teaching information seeking. Five school librarians from five different high schools (gymnasium) in Skåne participated in the study. The empirical data derives
Inom konkursrätten syftar bouppteckningseden till att förmå gäldenären att uppge alla tillgångar i konkursboet sanningsenligt. Uppsatsen behandlar bouppteckningsedens uppkomst ur ett rättshistoriskt perspektiv med det bakomliggande motivet att fastställa dess syfte och religiösa prägel. Vidare behandlas frågan vilken ställning bouppteckningen har i dagens konkursrätt och hur pass nödvändig den är Under bankruptcy law the estate inventory-oath aims to persuade the debtor to disclose all the assets of the bankruptcy estate truthfully. This essay deals with the origin of oath from a legal historical perspective, with of aim of defining its purpose. It further examines the status of the estate inventory-oath in the current bankruptcy law and how necessary it is in practice. A study of legal
This paper attempts to contribute to existing knowledge through an explicit threefold purpose. Initially, the importance of leverage in explaining equity return volatility is determined through two fixed effects panel data estimations. The panel dataset runs from 1990-2009 and includes 20 years worth of observations for the 45 firms on the Stockholm stock exchange for which data is available. The
As the case of the Deepwater Horizon reveals, the consequences of an oil spill or any other marine incident can be devastating. Although pollution from ships implies a much lesser scale, nevertheless there must be maximum efforts for preventing the possible risks and consequences of marine casualties. For centuries salvors have remained the ones who will provide the fastest response to a ship in
An improvement in photosynthetic rate promotes the growth of crop plants. The sink-regulation of photosynthesis is crucial in optimizing nitrogen fixation and integrating it with carbon balance. Studies on these processes are essential in understanding growth inhibition in plants with ammonium ((Formula presented.)) syndrome. Hence, we sought to investigate the effects of using nitrogen sources wi
The cortico-basal ganglia system is instrumental in the construction of movement, through its involvement in aspects such as action selection, initiation/termination and sequencing, though the precise role of the different structures and how they collaborate on a network level to allow us to fluidly change from one behavior to another has long proven to be elusive.We have here recorded neuronal acti
This paper considers instantaneous impulses in multibody dynamics. Instantaneous impulses may act on the multibody from its exterior or they may appear in its interior as a consequence of two of its parts interacting by an impact imposed by a unilateral constraint. The theory is based on the Euler laws of instantaneous impulses, which may be seen as a complement to the Euler laws for regular motio
