Recirculation of process water in the production of ethanol from softwood

In the production of ethanol from lignocellulosics, large quantities of water are needed in various process steps. In industrial processes, recycling of process streams is necessary to minimise fresh water requirements and decrease the amount of wastewater produced. This leads to increases in various substances, both volatile and non-volatile which inhibit fermentation. In the present Study ethano

Wheelchair Passengers and Local Public Transport Vehicles: Perceptions of Safety and Comfort

Popular Abstract in Swedish Målet med kollektivtrafik är bl a att anordna transportförsörjning för alla samhällsgrupper på ett samhällsekonomiskt effektivt vis. En grupp medborgare är rullstolsburna resenärer, vars speciella förutsättningar ställer särskilda krav på transportsystemets utformning. För att utröna dessa speciella förutsättningar på ett ansvarsfullt sätt, är det viktigt att man anläggEliciting wheelchair-seated passengers’ perspective of safety and comfort is both useful and mandatory, particularly for researchers, clinicians, transit authorities, and for operators during purchase and use of vehicle technologies in existing and planned future transport systems. Therefore, the overarching objective of this thesis was to delineate the question of safety and comfort as perceived

Development of a carbon nanotube paste electrode osmium polymer-mediated biosensor for determination of glucose in alcoholic beverages

This paper describes a new amperometric biosensor for glucose monitoring. The biosensor is based on the activity of glucose dehydrogenase (GDH) and diaphorase (DI) co-immobilized with NAD(+) into a carbon nanotube paste (CNTP) electrode modified with an osmium functionalized polymer. This mediator was demonstrated to shuttle the electron transfer between the immobilized diaphorase and the CNTP ele

Analysis of a Probing Control Strategy

In this paper we analyse an extremum controller based on a pulse technique. The idea is to superimpose probing pulses to the control signal and use the size of the pulse response in the output for feedback. The probing control strategy has been used with success for the control of the substrate feeding in E. coli cultivations. The stability analysis is done here for systems of Hammerstein type wit

Assessment of Left Ventricular Dysfunction and Remodelling by Determination of Atrioventricular Plane Displacement and Simplified Echocardiography

Heart failure is a common disease characterised by poor prognosis and frequent hospitalisations, constituting a major economic burden to society. Mortality and morbidity can be reduced by optimal treatment, requiring objective evaluation of cardiac function and anatomy. The development of symptomatic HF can be prevented by initiating adequate treatment in early stages when LVD is still asymptomati

Chronic suppurative otitis media in Tanzanian school children and its effects on hearing

OBJECTIVES: To compare different treatment regimens of chronic suppurative otitis media (CSOM) in school children, in regard to their consequence in hearing and discharge from the ear drum perforation. DESIGN: Randomised controlled trial. SETTING: Randomly selected primary schools within Dar es Salaam. SUBJECTS: Three hundred and twenty eight children between 5-17 years of age with CSOM in one or

5-ALA for photodynamic photorejuvenation - Optimization of treatment regime based on normal-skin fluorescence measurements

Background and Objectives: Photodynamic therapy using 20% 5 aminolevulinic acid (5-ALA) has recently been introduced as a new tool in optical skin rejuvenation. The primary objective of this study was to optimize incubation time, the topical delivery mechanism (vehicle) and the concentration of 5-ALA by detecting the dynamic changes of normal skin after 5-ALA application. The secondary objective w

Direct delivery of leptin to the hypothalamus using recombinant adeno-associated virus vectors results in increased therapeutic efficacy

The hormone leptin has been shown to be an afferent signal in a negative-feedback loop regulating body weight, and consequently, the administration of the gene product for the treatment of obesity has recently attracted considerable attention. Leptin is produced by adipocytes in response to increased trigyceride storage, and appears to affect body weight primarily through target cells in the hypot

Genome-wide survey of mRNA half-lives in Bacillus subtilis identifies extremely stable mRNAs

We have used DNA microarrays to survey rates of mRNA decay on a genomic scale in early stationary-phase cultures of Bacillus subtilis. The decay rates for mRNAs corresponding to about 1500 genes could be estimated. About 80% of these mRNAs had a half-life of less than 7 min. More than 30 mRNAs, including both mono- and polycistronic transcripts, were found to be extremely stable, i.e. to have a ha

Palliativ cancervård är en betydande del av urologin. Studie av det sista levnadsåret för patienter som dog av urologisk cancer

A total of 330 in-patient episodes at the urology ward, with a mean duration of 9.8 days, were registered in a study of 100 patients who died from urological cancer. Twelve patients spent more than two months of their last year of life at the urology ward. As many as 82% of the admittances were on an emergency basis. A total of 101 operations were performed on 84 patients; 47 patients received pal

Effect of murine strain on metabolic pathways of glucose production after brief or prolonged fasting

Background strain is known to influence the way a genetic manipulation affects mouse phenotypes. Despite data that demonstrate variations in the primary phenotype of basic inbred strains of mice, there is limited data available about specific metabolic fluxes in vivo that may be responsible for the differences in strain phenotypes. In this study, a simple stable isotope tracer/NMR spectroscopic pr

Hyperglycernia down-regulates apolipoprotein M expression in vivo and in vitro

Diabetes is associated with low concentrations of apoM in plasma. In db/db mice, ob/ob mice as well as in the alloxan-induced diabetic mouse, the low apoM levels are paralleled by decreased expression of the apoM gene. In the latter model, insulin substitution tended to reverse the low apoM expression. It is not known whether the impairment in apoM expression can be ascribed to hyperglycemia, insu

Fusion of farnesyldiphosphate synthase and epi-aristolochene synthase, a sesquiterpene cyclase involved in capsidiol biosynthesis in Nicotiana tabacum.

A clone encoding farnesyl diphosphate synthase (FPPS) was obtained by PCR from a cDNA library made from young leaves of Artemisia annua. A cDNA clone encoding the tobacco epi-aristolochene synthase (eAS) was kindly supplied by J. Chappell (University of Kentucky, Lexington, KY, USA). Two fusions were constructed, i.e. FPPS/eAS and eAS/FPPS. The stop codon of the N-terminal enzyme was removed and r
