A model has been formulated for the pyrolysis of wood. This model includes heat and mass transfer. Heat transfer in the material is assumed to take place by thermal conduction and convection. Mass transfer of volatile pyrolysis products and water vapour occurs under the influlence of gradients in to tal pressure. Pyrolysis is assumed to conform to an Arrheniusfunction, and vaporization occurs at a

Red blood cells may regulate tissue circulation and O-2 delivery by releasing the vasodilator ATP in response to hypoxia. When released extracellularly, ATP is rapidly degraded to ADP in the circulation by ectonucleotidases. In this study, we show that ADP acting on P2Y(13) receptors on red blood cells serves as a negative feedback pathway for the inhibition of ATP release. mRNA of the ADP recepto

Excited states in the T-z-1/2 nucleus Rb-75 were observed for the first time using the Ca-40(Ca-40,alpha p) reaction at 128 MeV. Identification was achieved using events detected by the Daresbury recoil separator in coincidence with gamma rays detected in the 45 element EUROGAM I Ge-detector array. Threefold events were used to build a decay scheme which consists of two rotational bands observed t

A new type of triangular phase diagram has been developed in which both the volume fractions and the shrinkage modes can be visualised and compared for the consolidation process in the paper dryer. The triangular phase diagrams show the development of the solid, the liquid and the gas volume fractions as well as the shrinkage relative to either ideal or no shrinkage of the sheets. Analysis showed

Popular Abstract in Swedish Parkinsons sjukdom uppstår när celler som producerar signalsubstansen dopamin i hjärnan dör. Detta leder till att de drabbade patienterna blir stela, får långsamma rörelser, svårt att påbörja och avsluta rörelser och även skakningar i framförallt armar och händer. Idag finns inget sätt att bota sjukdomen. Dock finns det läkemedel som kan lindra symptomen. Den vanligasteThe main pathological feature in Parkinson's disease is the progressive loss of dopamine neurons in the midbrain, which in turn leads to the appearance of motor deficits such as akinesia/bradykinesia (loss/slowness of movements), rigidity, postural imbalance and tremor. To this day, there is no cure for the disease, but there are medications to relieve the symptoms. The gold standard medication is

A search is conducted for the electroweak pair production of a chargino and a neutralino pp→χ1±χ20, where the chargino decays into the lightest neutralino and a W boson, χ1±→χ10W±, while the neutralino decays into the lightest neutralino and a Standard Model-like 125 GeV Higgs boson, χ20→χ10h. Fully hadronic, semileptonic, diphoton, and multilepton (electrons, muons) final states with missing tran

The toxin-antitoxin (TA) systems have been attracting attention due to their role in regulating stress responses in prokaryotes and their biotechnological potential. Much recognition has been given to type II TA system of mesophiles, while thermophiles have received merely limited attention. Here, we are presenting the putative type II TA families encoded on the genomes of four Geobacillus strains

Purpose: Postoperative bleeding after thyroid surgery remains a potentially lethal complication. Outpatient thyroidectomy is an increasing trend in the high volume centers. There is a need to identify risk factors for postoperative bleeding in order to select proper patients for outpatient thyroidectomy. This study aimed to investigate this issue using a national population-based register. Materia

Pseudomonas aeruginosa efficiently adheres to human tissues, including the lungs and skin, causing infections that are difficult to treat. Laminin is a main component of the extracellular matrix, and in this study we defined bacterial laminin receptors on P. aeruginosa. Persistent clinical P. aeruginosa isolates from patients with cystic fibrosis, wounds or catheter-related urinary tract infection

Background: In squamous cell vulvar cancer, sentinel node biopsy is accepted as standard treatment in well-defined patient groups and has reduced surgical morbidity considerably. Currently, due to the lack of evidence, it cannot be offered to patients with tumors of 4 cm diameter or greater or with multifocal tumors, or in local recurrences. Primary objective: This study is primarily a pilot and f

Herein, we describe the synthesis and X-ray structure of a new heteropentanuclear complex (2) containing a [Fe2 IIIZn3 II(μ-OH)3] structural unit and the unsymmetrical ligand H2L2-et. The molecular structure of (2) shows that it is formed by a basic dinuclear [FeIII(μ-OH)ZnII(L2-et)] unit that is connected to a second dinuclear [FeIII(μ-OH)ZnII(L2-et)] unit through a hydroxo bridge while a third Z

Searches for the Higgs boson decays H→ee and H→eμ are performed using data corresponding to an integrated luminosity of 139fb−1 collected with the ATLAS detector in pp collisions at s=13 TeV at the LHC. No significant signals are observed, in agreement with the Standard Model expectation. For a Higgs boson mass of 125 GeV, the observed (expected) upper limit at the 95% confidence level on the bran

Thanks to an intensive technological effort in the framework of the EUFELE collaboration, the European FEL at ELETTRA was able to break the previous record for the shortest wavelength of an FEL oscillator. Novel solutions were adopted for multilayer mirrors to allow FEL operation in the wavelength region between 160 and 190 nm, which is one of the main targets of the project. The characteristics o

Objectives: To explore availability, prices and affordability of essential medicines for diabetes and hypertension treatment in private pharmacies in three provinces of Zambia. Methods: A cross-sectional survey was conducted in 99 pharmacies across three Zambian provinces. Methods were based on a standardized methodology by the World Health Organization and Health Action International. Availabilit

The influence of grain boundaries on the mechanical properties of poly-crystalline metals is well known. Here we investigate the influence from a centrally placed grain boundary in nano-sized beams of Cu subjected to tensile loading. The crystallographic orientations in the grains are [100], [110] and [111]. The investigation is performed by means of molecular dynamic simulations employing the molThe influence of grain boundaries on the mechanical properties of poly-crystalline metals is well known.

Dagens planeringssystem är uppdelat på många aktörer och har traditionellt drivits av fokus på prognoser, kostnadseffektivitet, och samhällsekonomisk lönsamhet. Klimatutmaningen ställer delvis helt nya krav på planeringen, med ett fokus på att utveckla styrmedel som på ett kostnadseffektivt sätt leder till de utsläppsminskningar som behövs. I detta behövs en större uppmärksamhet på de sociala effe

Background Problem gambling is a public health issue and its comorbidity with other health conditions may provide an opportunity for screening in healthcare settings; however, a high level of uncertainty and a lack of research in the field remains. The objective of this study is to investigate potential associations between problem gambling and numerous other health conditions, including substance
