Water soluble acrylic acid grafted luminescent silicon quantum dots (Si-QDs) were prepared by a simplified method. The resulting Si-QDs dissolved in water and showed stable strong luminescence with peaks at 436 and 604 nm. X-ray photoelectron spectroscopy (XPS) was employed to examine the surface electronic states after the synthesis. The co-existence of the Si2p and C1s core levels infers that th

Within linguistics a word class is defi ned in grammatical terms as a set of words that exhibit the same syntactic properties. In this paper the aim is to argue that the meanings of different word classes can be given a cognitive grounding. It is shown that with the aid of conceptual spaces, a geometric analysis can be provided for the major word classes. A universal single-domain thesis is propos

Abstract in Finnish Arvioinnin kohteena oli vuosien 2008–2011 ja 2012–2015 aikana toteutettu pitkäaikaisasunnottomuuden vähentämisohjelmakokonaisuus, Paavo I ja Paavo II. Arvioinnissa keskityttiin ohjelmakokonaisuuteen ja sen eri osa-alueisiin näkökulmana asunto ensin -mallin toteuttaminen suomalaisessa yhteiskunnassa. Arviointiraportissa on kuvattu Iso-Britannian, Ruotsin ja USA:n asunnottomuustyThe review covered the whole of the programme to reduce long-term homelessness implemented during 2008–2011 and 2012–2015, Paavo I and Paavo II. The review focused on the programme as a whole as well as its different aspects from the point of view of implementing the Housing First model in Finnish society. The review report described work on homelessness done in the United Kingdom, Sweden and the

In the present study we have investigated the activity concentrations of (210)Pb, (210)Po as well as (7)Be in surface air of the North and South Atlantic (1988-1989), the Arctic Ocean (1991), and along the coastline of Siberia (1994) during succeeding expeditions in the Swedish Polar Research program. During the cruises in the Arctic Ocean during 1991-07-28 to 1991-10-04 the average air concentrat

Infrared spectra of partially deuterated water trimers have been investigated. It is found that HDO(H(2)O)(2) has a single, bound OD stretching fundamental, (HDO)(2)H(2)O two bound OD stretches. (HDO)(3) has a single, bound OD stretch and (H(2)O)(3) has a pair of bound OH stretches. Ab initio and discrete Fourier transform (DFT) calculations predict that the water trimer has C(1) symmetry with six

With the development of urbanization and deterioration of water environment, the fresh water shortage in eastern coastal cities of China is more and more serious. Desalination, as the only way to increase the amount of fresh water, should be more applied in this region, while the actual development is not as expected for some reasons. The study reviews the desalination status in China from the per

To improve compliance with abdominal aortic aneurysm (AAA) screening in low compliance areas, individually tailored invitations were developed in collaboration with a professional advertising agency. Compliance increased in two intervention municipalities from 71.4% in 2010-2012 to 78.1% in 2013 (p = 0.025), and was then higher [odds ratio 1.7; 95% confidence interval 1.1-2.6; p = 0.013] than in t

Several of the ingredients in fragrance mix I (FM I) have been shown to evaporate from petrolatum preparations applied in test chambers to an extent that can be suspected to affect the patch test result.

IN 2008 AND 2009, the European Commission conducted its Pharmaceutical Sector Inquiry based on a suspicion that a slower rate of approval for new drugs may have resulted from violations of European Union competition law. The Commission issued Preliminary and Final Reports detailing the findings of the Inquiry, which did not include any findings of the sort of competition law violations originally

A finite element plane stress parameter study of the global perpendicular to grain stiffness of timber structural elements such as beams and cross ties is presented. This stiffness is affected by the size and shape of the cross section, the growth ring pattern, the stiffness properties of the wood and the boundary conditions. Various rectangular sections with concentric circular growth rings with

Biomass burning is one of the largest sources of atmospheric trace gases and aerosols globally. These emissions have a major impact on the radiative balance of the atmosphere and on air quality, and are thus of significant scientific and societal interest. Several datasets have been developed that quantify those emissions on a global grid and offered to the atmospheric modelling community. However

Background For previously untreated children with severe hemophilia A, it is unclear whether the type of factor VIII product administered and switching among products are associated with the development of clinically relevant inhibitory antibodies (inhibitor development). Methods We evaluated 574 consecutive patients with severe hemophilia A (factor VIII activity, <0.01 IU per milliliter) who were

Molecular imprinting technology allows synthesis of polymers with specific recognition ability towards target pollutants, which show potential to selectively remove Highly Toxic Organic Pollutants (HTOPs) in the presence of common organic matrices that are thousands of times more abundant than the targets. This feature article summarizes the current development of molecular imprinting for removing

Clinical evidence accumulated from hemophilic patients during prophylaxis with recombinant activated factor VII (rFVIIa) suggests that the duration of the hemostatic action of rFVIIa exceeds its predicted plasma half-life. Mechanisms involved in this outcome have not been elucidated. We have investigated in vitro the redistribution of rFVIIa in platelets from healthy donors, patients with FVII def

The lipid phase of the thylakoid membrane is mainly composed of the galalctolipids mono- and digalactosyl diacylglycerol (MGDG and DGDG, respectively). It has been known since the late sixties that MGDG can be acylated with a third fatty acid to the galactose head group (acyl-MGDG) in plant leaf homogenates. In certain brassicaceous plants like Arabidopsis thaliana, the acyl-MGDG frequently incorp

While negative effects of human disturbance on animals living above the ground have been widely reported, few studies have considered effects on animals occupying cavities or burrows underground. It is generally assumed that, in the absence of direct visual contact, such species are less vulnerable to disturbance. Seabird colonies can support large populations of burrow- and cavity-nesting species
