Unlike many nanomaterials, nanocrystalline cellulose (CNC) is not synthesized from molecular or atomic components but rather extracted from naturally occurring cellulose. Undoubtedly, the exploitation of CNCs will become a bridge between nanoscience and natural resource products, which could play a major role in reviving the forest industry. In this work, CNC was successfully extracted from unusua
A method of realigning the quadrupole magnets in storage rings to achieve minimum dipole corrector strengths is described. The corrector strengths after realignment are mainly determined by Beam Position Monitor offsets relative to the quadrupole magnets they have been calibrated against and the extent to which magnet dipole errors stay constant during the realignment. The accuracy to which quadru
Chemical plasmid DNA (pDNA) gels were prepared by a cross-linking reaction with ethylene glycol diglycidyl ether (EGDE). Fluorescence microscopy (FM) and scanning electron microscopy (SEM) images of pDNA gels are reported. For the first time, the pDNA gels have been investigated with respect to their swelling in aqueous solution containing different additives, such as metal ions, polyamines, polyc
A label-free immunosensor for the direct detection of cholera toxin (CT) at sub-attomolar level has been developed based on potential-step capacitance measurements. Anti-CT antibody was adsorbed on gold nanoparticles (AuNPs) incorporated on a polytyramine-modified gold electrode. The concentration of CT was determined by detecting the change of capacitance caused by the formation of antibody-antig
Larsson, M. R., Bäckström, M., Michel, P.-O. & Lundh, L.-G. (2010). The stability of alexithymia during work in a high-stress environment: A prospective study of Swedish peacekeepers serving in Kosovo. Scandinavian Journal of Psychology. We applied a prospective design to reinvestigate the issue whether the sub-domains of alexithymia could be considered stable traits or distress-related states
Popular Abstract in Swedish Livskvalitet, motivation och kostnader vid rehabilitering av patienter med långvariga muskuloskeletala besvär Långvariga muskuloskeletala besvär är ett omfattande medicinskt, socialt och ekonomiskt problem i utvecklade länder. Syftet med avhandlingen var att utvärdera ett multidisciplinärt rehabiliteringsprogram som fokuserade på Basal Kroppskännedom och kognitiv och Prolonged musculoskeletal disorders (PMSD) is an escalating medical, social and cost problem in developed countries. The complexity of PMSDs has emphasised the need of developing effective multidisciplinary rehabilitation programme with a holistic approach. The aim of the thesis was to evaluate the outcome of a multidisciplinary rehabilitation programme focusing on Body Awareness Therapy and cogn
The high solubility in acidic solutions of N-bis(N',N'-diethyl-2-aminoethyl)-4-aminomethylphenyl-diphenylphosphine (N3P) make it a suitable candidate for study and comparison to the more commonly studied trisulfonated triphenylphosphine (TPPTS) ligand in the palladium catalysed aqueous hydrocarboxylation reaction. The catalyst employing N3P shows an inverted regioselectivity compared to the TPPTS
The aim of the Swedish educational policy is educational participation and academic achieivement for all children, irrespective of ethnic background. Majority language instruction is an important tool used to achieve this goal. We argue that taking lessons in Swedish-as-a-second-language (S2) sets children apart in their class and limits their possibilities to interact with Swedish children and th
Popular Abstract in Swedish Avhandlingen analyserar Guatemalas råvaruexport under perioden 1524-1945.In the integrated institutional-staples-‘vent for surplus’ approach, the opening of trade occurs because of initial demand. Once demand is determined, competitiveness is a function of transportation costs, entrepreneurship, capital, land and labour costs, as well as the role played by the State. When all these factors promote competitiveness within an institutional framework that decreased transac
A novel process for the production of biodegradable lubricant-based stocks from epoxidized vegetable oil with a lower pour point via cationic ion-exchange resins as catalysts was developed. This involves two steps, first, ring-opening reactions by alcoholysis followed by esterification of the resultant hydroxy group in the first step. The ring-opening reaction of epoxidized soybean oil with differ
Popular Abstract in Swedish Bakgrund: Det första elektrokardiogrammet (EKG) utfördes 1887 av Augustus Desiré Waller. Det innebar att spänningsskillnader mellan olika delar av hjärtat, under hjärtats arbete dvs. vid upprepade sammandragningar och avslappningar, kunde registreras med elektroder på kroppens yta. Metoden utvecklades vidare av Willem Einthoven, som fick nobelpriset för sitt arbete 1924Background and Methods: Signal-averaging ECG (SAECG), a bioelectrical processing method, is a further development of the conventional ECG. SAECG can detect voltage potentials in the microvolt range and provide a noise-reduced determination of QRS duration. Extended frequency spectra can be analysed. In adult patients after myocardial infarction it is used to predict the risk for arrhythmias and su
The aims of this thesis were to 1) compare different methods for detection of antibodies against thyroglobulin (TgAb) and thyroid peroxidase (TPOAb), particulary in children with chronic autoimmune thyroditis (AIT), 2) investigate if maternal enterovirus infection is a risk factor for development of AIT in offspring, 3) ascertain the prevalence of thyroid autoantibodies in cord blood sera from chi
We have analyzed the M-bcr breakpoint position in 133 Philadelphia-positive chronic myeloid leukemia patients and correlated the findings with clinical, hematologic, and cytogenetic data. We also investigated the splicing pattern of the BCR-ABL mRNA in 30 patients, using reverse transcriptase PCR. No statistically significant differences were found between breakpoint position within M-bcr and clin
We have investigated the growth of GaAs nanowires as a function of temperatures and source pressures on (I 1 1) B-oriented substrates in chemical beam epitaxy (CBE), to establish the mechanisms that govern wire growth and to optimize growth conditions. The grown nanowires were characterized with a scanning electron microscope (SEM). We found two mechanisms to be of importance for wire growth: (i)
Chronic treatment with epidermal growth factor (EGF) stimulates growth of all wall layers of the urinary tract in pigs and rats. Herein, we investigated the acute effects of EGF on detrusor smooth muscle activity. For in vivo examination, awake rats received EGF (75 micrograms/kg) intravenously and detrusor smooth muscle activity was monitored cystometrically. The EGF bolus caused no alteration in
This cross-sectional study was done in order to ascertain whether there is a lifelong beneficial effect on bone mineral density (BMD) of early, long-lasting, and intense physical exercise. Forty-eight male ex-weight lifters, mean age 64 years (range 50-79) participated. They had followed a training program of an average of 10 hours/week (range 4-20) for an average of 13 years (range 1-34). They ha
This working paper discusses the different Asian experiences of the Green Revolution from the late 1960s to the 1980s in the perspective of earlier developments of agricultural intensification. The intention of the paper is to identify common features and conditions contributing to the considerable success of Asian agriculture over the past 30 years. The authors argue that the Green Revolution mus
Due to the strongly kinetic nature of the chemical events leading to the formation of mesoscopically ordered inorganic-surfactant composite materials, detailed studies on the interdependency between the degree of inorganic condensation and the co-operative self-assembly is difficult to perform. We have therefore undertaken a study where organic polyelectrolytes are used as models for the inorganic
