RESEARCH QUESTION: According to the German Guidelines for Psychotherapy, psychotherapists need the consent of the respective insurance company to commence outpatient therapy. They have two options: (1) To begin a so-called short-term therapy (KZT) for up to 25 sessions--a quick and easy procedure requiring few formal expenses. Afterwards the therapist must provide the reasons for extending the therapy in a formal expert assessment request (extension request). (2) It is also possible to obtain the consent of the insurance company at the beginning of therapy (initial request) for up to 50 sessions (psychodynamic long-term therapy) or even for up to 160 sessions (analytical psychotherapy), both of which require the same expert assessment to be filled out beforehand (LZT)...

This paper investigates the effect of K(1.94)Zn(1.06)Ta(5.19)O(15) (KZT) addition on the sintering behavior and piezoelectric properties in lead free piezoelectric ceramics of (K(0.5)Na(0.5))NbO(3) (KNN). The apparent density of sintered KNN ceramics was increased with KZT addition, and a relative density of above 96.3% was obtained with the doping of over 0.5 mol% KZT. The maximum dielectric and piezoelectric properties of epsilon(T)(3)/epsilon(0) = 590, d(33) = 126 pC/N, k(p) = 0.42, and P(r) = 18 microC/cm(2) were obtained from 0...

Some results from ongoing studies of the transport of some neutral amino acids across the human erythrocyte membrane (L-tryptophan and L-leucine) at 25 degrees C are presented. The unidirectional flux into the cell at initial rate as a function of the substrate concentration can be described by a 3-parameter model (i.e. a carrier in parallel with an apparent leak component). From the estimated kinetic parameters an apparent membrane permeability of the carrier (substrate concentrations S1 smaller than Kzt 12) has been calculated...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
