In optically controlled quantum computers it may be favorable to address different qubits using light with different frequencies, since the optical diffraction does not then limit the distance between qubits. Using qubits that are close to each other enables qubit-qubit interactions and gate operations that are strong and fast in comparison to qubit-environment interactions and decoherence rates.

Popular Abstract in Swedish I plan to add a summary in Swedish at the WWW-page www.biokem.lu.se/education/theses/johannordthesis.htm

Popular Abstract in Swedish Hemicellulosa är en fantastisk källa av förnyelsebar råvara, vars användning har potental att bli kraftigt utökad i framtiden. Hemicellulosor är tillsammans, med lignin och cellulosa bland de mest förekommande klasserna av ämnen i växtcellernas väggar. Dessa tre beståndsdelar är tätt sammanlänkade, vilket gör det svårt att separera dem från varandra. Hemicellulosor är kHemicelluloses are tremendous sources of renewable raw materials, which utilisation have the potential to be highly increased in the future. Hemicelluloses are among the major groups of compounds in plant cell walls, together with cellulose and lignin. These three components are closely associated, making them difficult to separate from each other. Hemicelluloses are complex polysaccharides and tw

Grass pea (Lathyrus sativus) is a leguminous food crop, grown mainly in the tropical and subtropical regions. It has valuable nutrients, however consumption of the seeds is reported to cause lathyrism, due to the presence of a non-protein amino acid (?-ODAP). The present study deals with the development of a process for reducing the ?-ODAP content in grass pea seeds. The consequences of processin

Proteins are composed of 20 different amino acids. In the translation process, each of these 20 amino acids is specifically recognized by their cognate aminoacyl-tRNA synthetase. The fidelity of this recognition system is essential if translation is to function properly. The development of an in vitro system based on this recognition scheme would make a powerful analytical tool with which to analy

Background: HTLV-1 is endemic in Guinea-Bissau, and the highest prevalence in the adult population (5.2%) was observed in a rural area, Caio, in 1990. HIV-1 and HIV-2 are both prevalent in this area as well. Cross-sectional associations have been reported for HTLV-1 with HIV infection, but the trends in prevalence of HTLV-1 and HIV associations are largely unknown, especially in Sub Saharan Africa

Popular Abstract in Swedish Sammanfattning. Man brukar mena att domsförkunnelsen i Jesaja 1?39 har två brännpunkter. I det jag kallar den samhällskritiska diskursen fördöms överklassens livsstil i allmänhet och dess förtryck av de fattiga i synnerhet. I den utrikespolitiska diskursen möter vi istället en profet som förkastar nationens utrikespolitik, inte minst de anti-assyriska upproren. Min tes Scholars have traditionally identified two fundamental, and somewhat separate, discourses in Isaiah 1?39. In what might be labelled the social-critical discourse, we supposedly encounter a prophet who condemns the Jerusalemite elite for their complacent attitudes and decadent life-style in general, and for their more or less systematic oppression of the less fortunate in particular. This lack of s

Popular Abstract in Swedish Proteiner är nödvändiga beståndsdelar i en levande cell. Dels bygger de upp viktiga strukturer och dels katalyserar de kemiska reaktioner. Proteiner kodas av gener. Varje protein motsvaras av en gen. Vägen från gen till protein är densamma i alla organismer på jorden. Först transkriberas en gen till en molekyl kallad mRNA (budbärar-RNA, eng. messenger RNA). Detta mRNA aDegradation of mRNA is a controlled process which is as important for gene regulation as the synthesis of mRNA. This thesis focuses on mechanisms of mRNA stability and degradation in Bacillus subtilis, the model of Gram-positive bacteria. The aprE mRNA, encoding an exported protease named subtilisin, is extremely stable with a half-life of more than 25 minutes. Average mRNA half-lives in B. subtil

The 2008–2009 global financial crisis triggered ‘Green Energy Economy’ (GEE) policy packages to stimulate green growth in many countries. China soon became a leader and, supported by its 11th Five-Year Plan (2006–2010), devoted approximately one-third of its US$ 647 billion stimulus package to green energy technologies. Since then, numerous policy instruments have been implemented to encourage ‘Gr

In-situ, quasi-continuous measurements of atmospheric hydrogen (H-2) have been performed since October 2007 at the Cabauw tall tower station in the Netherlands. Mole fractions of H-2, CO and several greenhouse gases are determined simultaneously in air sampled successively at four heights, between 20 and 200 m above ground level. Rn-222 measurements are performed in air sampled at 20 and 200 m. Th

Thiabendazole (TBZ) is widely used as a pre-planting and post-harvest agricultural fungicide and as an anthelminthic in humans and animals. TBZ is of toxicological concern, since adverse effects including nephrogenic, hepatogenic, teratogenic and neurological effects have been reported in mammals. Occupational exposure can occur among agricultural workers and the general public may be environmenta

Biomass burning is one of the largest sources of atmospheric trace gases and aerosols globally. These emissions have a major impact on the radiative balance of the atmosphere and on air quality, and are thus of significant scientific and societal interest. Several datasets have been developed that quantify those emissions on a global grid and offered to the atmospheric modelling community. However

Background: Research in the last decades has clearly pointed to the important role of language and communicative level when trying to understand developmental trajectories in children with autism spectrum disorders (ASD). Aims: The purpose of this longitudinal study was to investigate whether (1) core language skills, measured as expressive vocabulary and grammar, and/or (2) pre-linguistic social-

Objective: To give an overview of the literature on knee proprioception in knee osteoarthritis (OA) patients. Method: A literature search was performed and reviewed using the narrative approach. Results: (1) Three presumed functions of knee proprioception have been described in the literature: protection against excessive movements, stabilization during static postures, and coordination of movemen

Background Chitosans of high molecular weights have emerged as efficient. nonviral gene delivery systems, but the properties and efficiency of well-defined low molecular weight chitosans ((.) 5 kDa) have not been studied. We therefore characterized DNA complexes Of Such low molecular weight chitosans and related their physical shape and stability to their efficiency as gene delivery systems in vit

A large body of evidence has demonstrated that one mechanism by which cholecystokinin (CCK) inhibits food intake through activation of CCK1 receptors (CCK1R) on vagal afferent neurons that innervate the gastrointestinal tract and project to the hindbrain. OLETF rats, which carry a spontaneous null mutation of the CCK1R, are hyperphagic, obese, and predisposed to type 2 diabetes. Recently, by intro
