The overall designing of one 90nm CMOS reflective-type phase shifter for the first three channels in 60 GHz band is described. The performance investigation is based on full wave electromagnetic analysis and optimization. The simulation predicts a phase tuning range of 360° as a function of control voltage with an average insertion loss of 5.5 dB over all phase states. The linearity of the phase s
Hard X-ray diffraction (XRD) using a nanofocused beam is used to measure both lattice contraction and bending in a single nanowire device under electric bias. The shape of the nanowire is reconstructed in 3D with sub-nanometer precision. As the bias voltage is gradually increased, nonreversible structural changes in the contact regions are observed, correlated with degradation of the electrical co
Simultaneous scanning Bragg contrast and small-angle ptychographic imaging of a single solar cell nanowire are demonstrated, using a nanofocused hard X-ray beam and two detectors. The 2.5 μm-long nanowire consists of a single-crystal InP core of 190 nm diameter, coated with amorphous SiO2 and polycrystalline indium tin oxide. The nanowire was selected and aligned in real space using the small-angl
Rare earth elements are strategic commodities in many countries, and an important resource for the growing modern technology industry. As such, there is an increasing interest for development of rare earth element processing, and this work is a part of further development of chromatography as a rare earth element separation process method.

The combination of coagulation/flocculation and discfiltration with ozonation to reduce nutrients and organic micro-pollutants in secondary effluent was studied in pilot scale at Lundåkraverket wastewater treatment plant in Landskrona, Sweden. With a chemical dose of 4 gAl3þ/m3 and 1.5 g/m3 cationic polymer as active material effluent water quality with regards to total phosphorous (Tot-P), suspenThe combination of coagulation/flocculation and discfiltration with ozonation to reduce nutrients and organic micro-pollutants in secondary effluent was studied in pilot scale at Lundåkraverket wastewater treatment plant in Landskrona, Sweden.

Holst-Ekströms bidrag är en essä som handlar om ett antal franska slott, från 1700 och 1800-talen, om minnets roll i förhållande till arkitekturen och litteraturen. Den behandlar också konstnären Marie Anderssons specifika relation till fotografi och arkitektur.This essay is about a number of French castles, from the 18th and 19th centuries, it concerns the rôle of architecture in relation to memory and litterature. It is also about the specific works of artist Marie Andersson, and how she photography and architecture.
Essän om konstnären Anders Stolts skulpturala verk Stilleben sätter in arbetena i konsthistoriska, teoretiska, arkeologiska och haptiska perspektiv.This essay on the sculptural works of Anders Stolt puts the works in different contexts: art historical, theoretical, aeaeological, and haptic.
Rrp6 is an exoribonuclease involved in the quality control of mRNA biogenesis. We have analyzed the association of Rrp6 with the Balbiani ring pre-mRNPs of Chironomus tentans to obtain insight into the role of Rrp6 in splicing surveillance. Rrp6 is recruited to transcribed genes and its distribution along the genes does not correlate with the positions of exons and introns. In the nucleoplasm, Rrp
BACKGROUND: Salmonella enterica serotype Enteritidis (SE) is considered to be one of the most potent pathogenic Salmonella serotypes causing food-borne disease in humans. Since a live bacterial vaccine based on surface display of antigens has many advantages over traditional vaccines, we have studied the surface display of the SE antigenic proteins, H:gm and SefA in Escherichia coli by the β-autot
5-Fluorouracil (5FU) is a fluoropyrimidine used for the treatment of solid tumors. 5FU is a precursor of dTTP and UTP during biogenesis, and it interferes with both DNA and RNA metabolism. The RNA exosome, a multisubunit complex with ribonucleolytic activity, has been identified as one of the targets of 5FU in yeast. Studies in human cells have shown that the catalytic subunit of the nuclear exoso
In Escherichia coli the codons CGG, AGG, UGG or GGG (NGG codons) but not GGN or GNG (where N is non-G) are associated with low expression of a reporter gene, if located at positions +2 to +5. Induction of a lacZ reporter gene with any one of the NGG codons at position +2 to +5 does not influence growth of a normal strain, but growth of a strain with a defective peptidyl-tRNA hydrolase (Pth) enzyme
The 1970s is a paradoxical decade. On the one hand, it marked the gradual demise of the industrial society and the end of the «Golden Age» of capitalism. On the other hand, the decade saw the renaissance of international banking and finance after almost half a century of retreat, thanks to the explosive growth of the Eurodollar market. International banking, which had remained dormant since the 19
On the 14th of January in 2004, Reem Raiyshi killed herself and four Israeli soldiers in a terrorist attack at the border between Israel and Gaza. Soon after the deed pictures on Reem, and her young son, were sent to media agencies in Europe - and to circulate on the Internet. Although the picture of Reem is her picture it is not unique, but forms part of a subculture: the ceremonial of the suicid
Aim: To investigate the fees charged by Swedish dentists for root fillings, coronal restorations and further dental interventions during a follow-up period of 5–6 years. Methodology: A total of 248 299 root fillings were linked with the tooth, the patient and the provider and entered into the Swedish Social Insurance Agency register in 2009. The data register also recorded the subsidy-based (sched
