Economic globalization causes an increasing international fragmentation (disintegration) of value-added-chains, whereby firms outsource components of production to foreign markets. There is a high level of concern about unwelcome distributional effects. This paper provides a theoretical treatment of this issue within a general Heckscher-Ohlin framework, allowing for an arbitrary number of goods...

Aluminum and gallium doped zinc oxide thin films with negative dielectric permittivity in the near infrared spectral range are grown by pulsed laser deposition. Composite ceramics comprising ZnO and secondary phase Al2O3 or Ga2O3 are employed as targets for laser ablation. Films deposited on glass from dense and small-grained ceramic targets show optical transmission larger than 70 % in the vis...

A high frequency (HF) ionospheric modification experiment was carried out between 25 September and 8 October 2004, using the EISCAT HF transmitter located near Tromsø, Norway. During this experiment the spectra of the stimulated HF sideband waves (stimulated electromagnetic emission or SEE) induced by the HF pump were observed using an interferometer consisting of three spaced receiving antenna...

Abstract Purpose To characterize and optimize the productivity of melanin using an extremotolerant actinobacterium, Dietzia schimae NM3, for first time. Methods An extracellular brown pigment produced by D. NM3 in nutrient broth cheese whey medium adding L-tyrosine. The extracted was analyzed UV-visible, HPLC, FTIR assays. radical scavenging activity (by DPPH) sun protection factor (SPF) were m...

Reverse osmosis (RO) spiral wound membrane generation reached 93.5% in 2020, resulting 14,000 tons of used RO membranes being discarded annually into landfills, which is unprecedented. The current study aims to chemically convert the end-of-life membrane, followed by its performance evaluation and microbial removal efficiency on three different sources water, i.e., tap water (TW), integrated co...

Candida albicans biofilms play a key role in denture stomatitis, one of the most common oral pathologies in elderly people. Because biofilms are highly resistant to antifungals, new pharmacological strategies are needed. Aspirin and nitric oxide-donor molecules have both shown antibiofilm effects on C. albicans, making them promising candidates for treatment. In this study, we evaluated the ant...

At Johannes Kepler University a neural-net-similar associative model has been developed. The basic model consists of very simple nodes with just two attributes, a binary stamp and a ternary charge. The connections between the nodes do not have any additional information such as weights. Nevertheless it was possible to construct a system consisting of such elementary components which is able to ...

OBJECTIVE To compare length of stay and total hospital costs among patients admitted to hospital under the care of family physicians who were their usual health care providers in the community (group A) and patients admitted to the same inpatient service under the care of family physicians who were not their usual health care providers (group B). DESIGN Retrospective observational study. SE...
