We describe the synthesis and fluorescence properties of a Fura-2FF-based fluorescent Ca(2+) indicator that can be covalently linked to SNAP-tag fusion proteins and retains its Ca(2+) sensing ability after coupling to protein.

In the educational context it is examined the teacher-stress association. The teacher’s stress is related with variables of academic environment, of out of the school and of the teacher. The impact of that association can be see in the teacher’s health, in his achievement and in the quality of the teaching-learning process. With the objective to present one view of how issue is being considered...

We demonstrate that an oft-used indirect attitude assessment technique—the attitude activation paradigm—accurately assesses attitudes only when participants attend to the prime stimuli during the attitude activation task. Attitude activation attitudes toward obviously valenced words (e.g., torture, liberty) were more sensitive to attitude valence and extremity when participants were required to...

This paper presents some aspects related to the issues of aggregating economic indicators. Departing from the research of Gh. Paun (1983) we will prove a theorem which states that under certain, natural assumptions, it is impossible to obtain an optimum aggregation. Unlike the original work of Paun, in this paper we are giving a rather simple proof of this theorem.

The validity of the Michaelis-Menten-Briggs-Haldane approximation for single enzyme reactions has recently been improved by the formalism of the total quasi-steady-state approximation. This approach is here extended to fully competitive systems, and a criterion for its validity is provided. We show that it extends the Michaelis-Menten-Briggs-Haldane approximation for such systems for a wide ran...

In December 2003, seventeen years after the first UK research assessment exercise, Italy started up its first-ever national research evaluation, with the aim to evaluate, using the peer review method, the excellence of the national research production. The evaluation involved 20 disciplinary areas, 102 research structures, 18,500 research products and 6,661 peer reviewers (1,465 from abroad); i...

Ameisen: Die heimliche Weltmacht (Ants: Nature's Secret Power) is a nature documentary about ants. Wolfgang Thaler wrote, filmed, and directed the film, which focuses on the work of ant researcher Bert Hölldobler. The 2004 film was produced by Adi Mayer Film for Österreichischer Rundfunk (Austrian Broadcasting), a public service broadcaster headquartered in Vienna, Austria. Ants: Nature's Secre...

The problem of slow drilling in deep shale formations occurs worldwide causing significant expenses to the oil industry. Bit balling which is widely considered as the main cause of poor bit performance in shales, especially deep shales, is being drilled with water-based mud. Therefore, efforts have been made to develop a model to diagnose drilling effectivity. Hence, we arrived at graphical cor...

BACKGROUND AND PURPOSE In congenital anosmia, the OB and OT can be aplastic or hypoplastic. In clinical routine, these are sometimes difficult to assess. We thus wanted to investigate morphologic differences of the OS in patients with IA since birth or early childhood in comparison with controls, to investigate whether there is a depth of OS that is predictive of IA. MATERIALS AND METHODS Wit...
