A 26 GHz quadrature voltage controlled oscillator designed in a 0.13-um CMOS process is presented. It consists of two differential oscillators coupled to oscillate in quadrature through transistors and mutual inductance between the source nodes. The oscillator measures a frequency tuning range of 3.1%, a worst case phase noise of -96 dBc/Hz at 1 MHz offset over the tuning range at a 1.35V supply
Popular Abstract in Swedish Med utgångspunkt från svensk-italienska ungdomars erfarenhet av att växa upp med två kulturer, vill författaren, utifrån ett pedagogiskt perspektiv, ge en beskrivning av innebörden i tvärkulturell fostran. Tvärkulturell fostran i den här studien innebär fostran med betydande inslag från minst två klart skilda kulturtraditioner, den svenska och den italienska. Den empiriThe present study dealt with what occurs in a social-cultural rearing-process when the parents derive from two different cultural traditions. It is a qualitative case study, with an ethnographically inspired approach, which considers processes rather than outcome, context rather than any specific variable and discovery rather than confirmation. The empirical data consist of interviews made with 41
Popular Abstract in Swedish Avhandlingen beskriver fonologin, morfologin och syntaxen för Lalo-språket, närmare bestämt som detta talas i Longjie landsortskommun i provinsen Yunnan i Kina. Lalo är ett språk som talas av ca 500 000 människor i sydvästra Kina. Språket tillhör burmesisk-yipho-språken, och har SOV-ordföljd, toner, fonationstyp, klassmärken m m. Avhandlingen är baserad på fältdata, iThe thesis is a descriptive reference grammar of the present-day Lalo language as spoken in Longjie township in Yunnan province of Southwestern China. It constitutes a presentation of empirical data collected during field work in Longjie township, and includes as survey of the phonology, morphology and syntax of the language. A word-list as well as text samples are appended to the thesis. Lalo is
An automatic time sequence filter sampler has been developed for atmospheric aerosol particle sampling of ambient air and subsequent analysis for elemental composition using the proton beam of a Van de Graaff accelerator. Some features of the operation of the sampler are given, the retention of particles by the filter material are discussed, examples of the type of data obtained are presented, and
Popular Abstract in Swedish I det här arbetet har vattenlösningar av cellulosabaserade polymerer studerats. En polymer är en lång molekyl som består av många sammanlänkande repeterande enheter. Längs den vattenlösliga polymerryggraden har korta hydrofoba (vattenskyende) kedjor ympats, vilket resulterar i så kallade ympsampolymerer. I vattenlösning bildas ett polymernätverk genom att de hydrofoba gThe properties of hydrophobically modified cellulose derivatives in aqueous mixtures with various other molecules have been investigated. Mixtures of a hydrophobically modified polymer and alkali-sensitive, degradable surfactants gave rise to time-dependent viscosities. With time, the viscosity decreased continuously or went through a maximum, depending on the initial surfactant concentration. Th
Drick kranvattens syfte är att öka ungdomars medvetenhet om kranvattnets värde. Projektet innehåller kranvattenautomater till skolorna och färdiga lektioner på drickkranvatten.se. Utvärderingen visar på en positiv inställning hos lärare och elever till projektet och till frågeställningar om vatten.
Three methods are suggested to identify and quantify flashback and flash forward events based on chemiluminescence recordings of swirling flames. The approaches differ in the procedure to determine the instantaneous flame position. The results revealed that the most robust method is to determine a threshold relative to the instantaneous maximum intensity. Analysis of the complete dataset indicated
Parts of large spiral galaxies, such as the Milky Way and Andromeda, are believed to have formed from the accretion of several smaller galaxies. Remnants of this chaotic merging era, such as dwarf spheroidal (dSph) galaxies, are visible in the outskirts of large galaxies. dSph galaxies are characterized by their low luminosity, low surface brightness and high fraction of dark matter. Determining t
The flexion of the verb in the Norwegian language for the indicative mood present tense has only one morphologic form, no matter the person and the number. The Punjabi language (spoken by more than 90 million people) is an Indo-Arian language (an immense subgroup of the Indo-Iranian languages, having more than 900 million speakers). The Punjabi language is closely related to Romany (Gipsy) languag
Methods to collect rain water and prevent runoff in agricultural areas are described. The distribution of solutes in soil columns is is investigated in several environments.
The dissertation seeks to problematize the public debate which in recent years has made many people interested in and committed to the region. The empirical basis of the study is some of the regions of southern Sweden which have served as an important platform in the last thirty or forty years when the political and economic establishment has acted and argued in various contexts. The fundamental q
Was there a connection between St. Mauritius and the oldest church in Dalby and what is the evidence for such a supposition? And, if such a connection can be established, what can be concluded about its impact on the formation and character of the ecclesiastical setting of early medieval Dalby? The idea about a connection between St. Mauritius and the oldest church in Dalby was introduced by the
Popular Abstract in Swedish Cytokrom P450 är en grupp enzymer som introducerar alkoholgrupper i främst icke-vattenlösliga ämnen. Alkoholgupperna gör dessa föreningar mer vattenlösliga och känsliga för fortsatta reaktioner. Cytokrom P450-enzymer återfinns i de tre domäner allt levande kan indelas i: eukaryoter (djur, växter, svampar, protozoer m.m.), bakterier och arkeér (ett slags bakterier som skCytochromes P450 constitute a super-family of heme containing mixed function mono-oxygenases that is found in all branches of life. They introduce single oxygen atoms, mostly in the form of hydroxyl groups, into lipophilic substances and thereby render them more hydrophilic and susceptible to further reactions. Little is known about the bacterial cytochromes P450. I have in my thesis given an over
In normal light-in-flight holography the largest time difference that can be created in the image is when the reference light falls nearly parallel with the photographic plate. In that case, where the pulse front is perpendicular to the direction of propagation, the time scale on the plate is given by the speed of light. Thus the time it takes for the reference light to go from one side of the pla
