Formation of macroporous self-assembled hydrogels through cryogelation of Fmoc-Phe-Phe.

In this study, it was found that macroporous hydrogels were formed when self-assembly of fluorenyl-9-methoxycarbonyl (Fmoc)-diphenylalanine (Phe-Phe) peptides was induced using glucono-δ-lactone (GdL) in apparently frozen samples. Formed cryogels exhibited a heterogeneous structure with pore walls of densely packed fibres of assembled dipeptides and pores in the range 10-100μm. Hydrogels formed fr

Children's experiences of acute hospitalisation to a paediatric emergency and assessment unit--a qualitative study.

Short-stay treatment has become a popular form of care as a strategy to cope with increased demands on health care. There is little research that considers children's experiences of acute hospitalisation to a short-stay care facility such as a Paediatric Emergency and Assessment Unit (PEAU). This study explored the experiences of eight children aged 8-10 years. Semi-structured interviews were carr

Formalisation and flexibilisation in organisations - Dynamic and selective approaches in corporate innovation processes

A classic problem in organising corporate innovation projects is the tension between formalisation and flexibilisation. Connecting this discussion to the younger debate on ambidexterity, this paper asks how organisations balance informal and formal, flexible and inflexible ways of working in their innovation projects. It derives a way to break down formalisation and flexibilisation into the dimens

Fiscal Incentives, Public Spending, and Productivity – County-Level Evidence from a Chinese Province

This article develops a new empirical approach to analyze the potential link between fiscal decentralization and economic efficiency based on a stochastic frontier model with spatial error correction. Fiscal decentralization is not considered to be a source of growth in itself but an incentive scheme that impacts local governments’ spending as a means to improve investment conditions. Panel data f

Tropospheric Photolysis Rates of the Acetaldehyde Isotopologues CD3CHO and CD3CDO Relative to CH3CHO Measured at the European Photoreactor Facility.

Acetaldehyde is a hazardous pollutant found in indoor and ambient air. Acetaldehyde photolysis is pressure- and wavelength-dependent with three distinct product channels. In this study, the photolysis rates of CH3CHO, CD3CDO, and CD3CHO are studied in natural tropospheric conditions using long path FTIR spectroscopy, at the European Photoreactor Facility (EUPHORE) in Valencia, Spain. The average r

Search for Dilepton Resonances in pp Collisions at root s 7 TeV with the ATLAS Detector

This Letter reports on a search for narrow high-mass resonances decaying into dilepton final states. The data were recorded by the ATLAS experiment in pp collisions at root s = 7 TeV at the Large Hadron Collider and correspond to a total integrated luminosity of 1.08 (1.21) fb(-1) in the e(+)e(-) (mu(+)mu(-)) channel. No statistically significant excess above the standard model expectation is obse

Switching clotting factor concentrates: considerations in estimating the risk of immunogenicity

The development of neutralizing antibodies to factor VIII (FVIII) is the most serious complication of therapy for haemophilia A. There is now excellent documentation that a large number of both genetic and environmental factors contribute to the risk of FVIII inhibitor incidence. One of the environmental factors that has been proposed as an influence on this complication is the occurrence of FVIII

Future fire emissions associated with projected land use change in Sumatra

Indonesia has experienced rapid land use change over the last few decades as forests and peatswamps have been cleared for more intensively managed land uses, including oil palm and timber plantations. Fires are the predominant method of clearing and managing land for more intensive uses, and the related emissions affect public health by contributing to regional particulate matter and ozone concent

Fluctuations, saturation, and diffractive excitation in high energy collisions

Diffractive excitation is usually described by the Good-Walker formalism for low masses, and by the triple-Regge formalism for high masses. In the Good-Walker formalism the cross section is determined by the fluctuations in the interaction. In this paper we show that by taking the fluctuations in the BFKL ladder into account, it is possible to describe both low and high mass excitation by the Good

Continuation of TNF blockade in patients with inflammatory rheumatic disease. An observational study on surgical site infections in 1,596 elective orthopedic and hand surgery procedures

BACKGROUND: Increased infection risk in inflammatory rheumatic diseases may be due to inflammation or immunosuppressive treatment. The influence of tumor necrosis factor (TNF) inhibitors on the risk of developing surgical site infections (SSIs) is not fully known. We compared the incidence of SSI after elective orthopedic surgery or hand surgery in patients with a rheumatic disease when TNF inhibi

Ethnic enclaves and risk of psychiatric disorders among first- and second-generation immigrants in Sweden

Some non-Western immigrant groups in Europe have elevated risk of psychosis relative to native-born. It is hypothesized that neighborhood ethnic density moderates this risk. Immigration to Sweden has increased substantially recently, particularly from the Middle East. This study examined the relationship between neighborhood ethnic density (i.e., living in an immigrant enclave) and risk of psychot

Electromechanical Behavior of Interdigitated SiO2 Cantilever Arrays

Bending and first flexural mode vibration behavior of electrostatic actuated nanometer-sized interdigitated cantilever arrays are characterized under vacuum conditions. The "pull-in" effect in dc driving and the "hard spring effect" in ac driving are observed. A mass sensitivity of 20 fg is expected for our devices due to the ultra-small mass of the arm and relative high.. factor. The mass-spring

Beyond the renaissance of the traditional Voss sheep's-head meal: Tradition, culinary art, scariness and entrepreneurship

Attempts have been made to make traditional local foods a part of the tourists' experiences, but few have caught great interest among the tourist and leisure consumers. An exception is the Norwegian traditional Sheep's-head meal. This article focuses on driving factors behind this success. Sheep's heads have been continuously available and used at private meals, albeit the status of the meals has

Listing Triangles

We present new algorithms for listing triangles in dense and sparse graphs. The running time of our algorithm for dense graphs is O~(n^ω+n^3(ω−1)/(5−ω)t^2(3−ω)/(5−ω)), and the running time of the algorithm for sparse graphs is O~(m^2ω/(ω+1)+m^3(ω−1)/(ω+1)t^(3−ω)/(ω+1)), where n is the number of vertices, m is the number of edges, t is the number of triangles to be listed, and ω < 2.373 is the expo
