Quinoa stalk (Chenopodium quinoa Willd.) from agricultural crop residue, totora (Schoenoplectus tatora) and o-macrophytes (aquatic flora) from Lake Titicaca (on the Bolivian Altiplano) were studied in a wet anaerobic co-digestion process together with manure front llama, cow and sheep. Anaerobic semi-continuous experiments were performed in (10) 2-1 reactors at a temperature of 25 degrees C with 3
We report on a single-molecule readout scheme on total internal reflection fluorescence microscopy (TIRFM) demonstrating a detection limit in the low fM regime for short (30-mer) unlabeled DNA strands. Detection of unlabeled DNA targets is accomplished by letting them mediate the binding of suspended fluorescently labeled DNA-modified small unilamellar vesicles (Ø approximately 100 nm) to a DNA-mo
Popular Abstract in Swedish None.This thesis presents numerical investigations and simulations of fixed bed combustion of wood, models for predicting thermal radiative properties of particles and gases related to the combustion of wood, and a review of heat load calculations in gas turbines. All subjects have a common factor in thermal radiation. One 2D and one 3D model were considered for the fixed bed combustion. The introducto
Background. Decompressive craniectomy (DC) is an option for the treatment of increased intracranial pressure resulting from an acute neurological insult, including insults caused by trauma. When the brain swelling has receded, the skull is reconstructed with a wide choice of materials, each with its own advantages and disadvantages in terms of cost, cosmetic appearance, biocompatibility, implant s
High-sensitive multi-species detection around 1550 nm using a modulated grating Y-branch, MG-Y, diode laser tunable between 1529 nm and 1565 nm is presented. The MG-Y diode laser is based on the Vernier effect of two modulated gratings, and exhibits quasi-continuous tuning over 36 nm. Multi-species detection is achieved by fast sequential scanning of single absorption lines of CH4, CO, C2H2, and C
An incorrect, superficial suckling technique in breastfeeding frequently leads to milk congestion and sometimes mastitis. In the present study we have examined whether milk congestion may affect levels of the atypical opioid beta-casomorphin-8 in milk and in plasma. We also investigated whether the rate of acute psychosis during the first half year after parturition has declined in Sweden over the
Non-stretched laminar burning velocities, SL, of acetaldehyde + air mixtures at initial gas mixture temperatures, T, of 298, 318, 338, 348 and 358 K are reported for the first time. The flames were stabilized on a perforated plate burner at 1 atm using the heat flux method at conditions where the net heat loss from the flame to the burner is zero. Uncertainties of the measurements were analyzed an
Fuel cells are electrochemical devices that directly transform chemical energy into electricity, which are promising for future energy systems, since they are energy efficient and, when hydrogen is used as fuel, there are no direct emissions of greenhouse gases. The cell performance depends strongly on the material characteristics, the operating conditions and the chemical reactions that occur ins
Both timber and glass are materials that have aesthetically pleasing properties. An appealing idea is to combine them to overcome the drawbacks and utilise the beneficial mechanical properties. Adhesive bonding with an appropriate adhesive could provide a uniform stress distribution at the transition between the materials.
This report presents a study of three different adhesives, silicon
Popular Abstract in Swedish Nu levande fåglar delas traditionellt in i två grupper. Den ena gruppen är Palaeognathae och omfattar ratiter (struts, nandu etc.) och stubbstjärthöns. Den andra gruppen, Neognathae, representerar alla övriga fåglar, drygt 20 ordningar med över 9.000 arter. Grunden för denna uppdelning utgörs i första hand av morfologiska studier av fåglarnas gommar. Man har ansett att The Class Aves (birds) is generally divided into two main groups - the Palaeognathae and the Neognathae. Paleognathous birds are the flightless ratites and the tinamous, while Neognathae include all other extant birds (more than 9,000 species). This opinion has prevailed for more than a century and is primarily based on morphological studies of the avian bony palate. In this study, the relationsh
Mycorrhizal symbioses are formed between plant root systems and compatible fungal hyphae that results in a complex mixed structure. They are found in all ecosystems and with the majority of land plants such as forest trees or crops that are of commercial interest. Mutual exchange of nutrients between the two symbionts is central to the successful functioning of the symbioses. In order to understan
Popular Abstract in Swedish Fågelflyttning omfattar några av de mest fascinerande beteendemässiga anpassningarna vi finner i naturen. Hos många fågelarter flyttar unga fåglar obereoende av erfarna vuxna individer och kräver således medfödd information om flyttningsvägar, rastning och övervintringsområden. Denna information har visat sig bestå av ett nedärvt program som innehåller flyttningsriktninIn many species of birds juveniles migrate independently of experienced adults and thus have to rely on innate information about migratory routes and wintering area. This information is encoded as a set of inherited migratory directions and a timing schedule that provides information on when and how far to migrate. Apart from these remarkable behavioral adaptations, migration also requires several
Popular Abstract in Swedish Avhandlingen handlar om lungornas funktion hos för tidigt födda (prematura) barn med brist på surfaktant, ett ämne som normalt ska finnas i lungorna, och hur lungfunktionen hos sådana barn kan förbättras genom tillförsel av det saknade ämnet utifrån. I avhandlingen har också använts en djurmodell (för tidigt födda lamm) för att studera hur konstgjord andning vid födelseThe thesis investigates lung function and the effects of rescue surfactant treatment in mechanically ventilated preterm human infants with respiratory distress syndrome (RDS), and the effects of ventilation at birth on the response to surfactant supplementation in preterm lambs. To assess lung function, the author recorded static pressure-volume (P-V) curves during passive deflation from total lun
Methods: The study population of healthy adult volunteers was divided into a sample for development of a prediction model (n = 63) and a testing sample (n = 30). Magnetic resonance imaging data were used to assess anatomical characteristics of the left ventricle: the angle between papillary muscles (PMA), the length of the left ventricle (LVL) and left ventricular mass (LVM). Twelve-lead electroca
In this article, we describe a third-generation amperometric glucose biosensor working under physiological conditions. This glucose biosensor consists of a recently discovered cellobiose dehydrogenase from the ascomycete Corynascus thermophilus (CtCDH) immobilized on different commercially available screen-printed electrodes made of carbon (SPCEs), carboxyl-functionalized single-walled carbon nano
Model studies of the subtype B and non-subtype B integrases are still required to compare their susceptibility to antiretroviral drugs, evaluate the significance of resistance mutations and identify the impact of natural polymorphisms on the level of enzymatic reactivity. We have therefore designed the consensus integrase of the HIV-1 subtype A strain circulating in the former Soviet Union territo
BACKGROUND: In order to determine myocardial salvage, accurate quantification of myocardium at risk (MaR) is necessary. We present a validated novel automatic segmentation algorithm for quantification of MaR by myocardial perfusion SPECT (MPS) in patients with acute coronary occlusion. METHODS AND RESULTS: Twenty-nine patients with coronary occlusion were injected with a perfusion tracer before re
This work used a low-cost wireless electroencephalography (EEG) headset to quantify the human response to different cognitive stress states on a single-trial basis. We used a Stroop-type color⁻word interference test to elicit mild stress responses in 18 subjects while recording scalp EEG. Signals recorded from thirteen scalp locations were analyzed using an algorithm that computes the root mean sq
Type 2 diabetic patients often die because of end-stage renal failure, but no definitive reliable factor predicting long-term renal outcome has been identified. We tested whether a renal arterial resistance index (R/I) >= 80, using Doppler ultrasound technique, was predictive of worsening renal function. The primary end points of the study were 1) the course of glomerular filtration rate (GFR) and
The cortical microtubules determine how cellulose microfibrils are deposited in the plant cell wall and are thus important for the control of cell expansion. To understand how microtubules can control microfibril deposition, the components that link the microtubules to the plasma membrane (PM) of plant cells must be isolated. To obtain information on the properties of the tubulin-membrane associat
