Signal frequency studies of an environmental application of a 65 nm region ion sensitive field effect transistor sensor

A rapid and sensitive novel type of bioelectronic Region Ion Sensitive Field Effect Transistor (RISFET) nanosensor was constructed on a chip with a 65 nm sensing electrode gap. The RISFET nanosensor was demonstrated for the environmental pesticide analysis of neurotoxic organocarbamate/carbofuran. The linear range for carbofuran analysis is ac signal frequency dependent, studied in the range (500

Diels-Alder adducts derived from the natural phthalide Z-ligustilide

Z-Ligustilide, a naturally occurring phthalide isolated from Ligusticum porteri, underwent Diels-Alder reactions with different dienophiles yielding novel tricyclic products with potentially interesting biological properties. Where selectivity was possible, the reactions performed showed regio- and stereoselectivity. The experimental results with ethyl acrylate were compared with the selectivity p

Low-power voltage-controlled oscillators in 90-nm CMOS using high-quality thin-film postprocessed inductors

Wafer-level packaging (WLP) technology offers novel opportunities for the realization of high-quality on-chip passives needed in RF front-ends. This paper demonstrates a thin-film WLP technology on top of a 90-nm RF CMOS process with one 15-GHz and two low-power 5-GHz voltage-controlled oscillators (VCOs) using a high-quality WLP or above-IC inductor. The 5-GHz VCOs have a power consumption of 0.3

Heavy metal concentrations in European mosses: 2000/2001 survey

The heavy metals in mosses survey was originally established in 1980 as a joint Danish-Swedish initiative under the leadership of Angstromke Ruhling, Sweden and has, since then, been repeated at five-yearly intervals with an increasing number of countries and individuals participating. Twenty-eight European countries, almost 7000 sites and about 100 individuals have been involved in the most recen

Inflammatory indices for chronic bronchitis and chronic obstructive airway disease. Cell populations in bronchial and bronchoalveolar lavage

The development of chronic bronchitis (CB) and chronic obstructive airway disease (COAD) seems to be related to inflammatory changes of airway structure. However, the cause and the exact location and type of these changes resulting in altered airway function are not known. Mucosal inflammation is characterized by the recruitment of granulocytes, macrophages and lymphocytes as well as by the sheddi

THE ROLE OF PHOSPHODIESTERASE 3B IN CAMP-MEDIATED REGULATION OF INSULIN SECRETION

Type 2 diabetes mellitus (T2DM) is characterized by various combinations of ?-cell failure and insulin resistance leading to hyperglycemia and glucose intolerance. In order to maintain glucose tolerance in the insulin resistance state, increased insulin secretion is a requirement and it is because of inadequate islet adaptation that glucose intolerance develops in T2DM. The pathophysiology of T2DM

The effect of nutrient stress on developmental instability in leaves of Acer platanoides (Aceraceae) and Betula pendula (Betulaceae)

Studies of developmental stability can provide insights into the amount of genetic or environmental stress experienced by individuals or populations. In the present study, we used young plants of Acer platanoides (Norway maple) and Betula pendula (silver birch), two distantly related tree species with widely different leaf morphologies, to compare the expression of developmental instability in two

Högpresterande betongs hydratation, struktur och hållfasthet

Syftet med projektet var att jämföra egenskaper hos s k högpresterande betong, d v s betong med mycket låga vattenbindetal (vbt) med motsvarande egenskaper hos normala betongkvaliteter. Studerade egenskaper är hydration, hållfasthetstillväxt och fukttransportegenskaper. I hydrationsstudierna ingår analys av hydratvattenmängd, kemisk krympning och värmeutveckling.

A network-based analysis of the late-phase reaction of the skin

Background: The late-phase reaction (LPR) of the skin is an in vivo model of allergic inflammation. Objective: We sought to identify disease-associated pathways in the LPR using a network-based analysis. Methods: The LPR was examined by means of DNA microarray analysis of skin biopsy specimens from 10 patients with allergic rhinitis and 10 healthy control subjects. The results were further analyze

Density-functional theory applied to Rh(111) and CO/Rh(111) systems: Geometries, energies, and chemical shifts

We present extensive density-functional theory (DFT) based calculations of the clean Rh(111) surface and of CO/Rh(111) overlayer systems. We study both ground-state structural properties and core-level shifts from differences in total energies at different coverages and adsorption sites. Most results are obtained using using norm-conserving or ultrasoft pseudopotentials. The overall reliability of

Can care of elderly be measured? A method for estimating the individual care of recipients in community health care

BACKGROUND: Almost every country in the Western world has great difficulties allocating enough financial resources to meet the needs in the care of the increasing elderly population. The main problem is common to all countries and concerns the efforts to meet elderly persons' needs on an individual level while still maintaining society's responsibility for distributing justice. The aim of this stu

On error exponents for woven convolutional codes with one tailbiting component code

An error exponent for woven convolutional codes (WCC) with one tailbiting component code is derived. This error exponent is compared with that of the original WCC. It is shown that for WCC with outer warp, a better error exponent is obtained if the inner code is terminated with the tailbiting method. Furthermore, it is shown that the decoding error probability decreases exponentially with the squa

MRI assessment of haemophilic arthropathy

Popular Abstract in Swedish Blödarsjuka (hemofili) är en recessiv genetisk sjukdom orsakad av en defekt i X-kromosomen som leder till förlängd koagulationstid på grund av brist eller avsaknad av koagulationsfaktorerna VIII eller IX i blodet. Kvinnor är anlagsbärare, medan män utvecklar symptom. Hemofili förkommer sporadiskt som följd av spontan mutation likaväl som ärftligt inom vissa släkter, ochHaemophilia is a recessive genetic bleeding disorder in which coagulation time is prolonged due to the absence or malfunction of either of the serum proteins Factor VIII or IX. Joint destruction following repeated haemarthroses is the main cause of morbidity in haemophiliacs, and such arthropathy can be prevented or postponed by implementing prophylactic therapy with factor concentrate at an early
