Synthesis and pharmacological properties of TOAC-labeled angiotensin and bradykinin analogs
(Elsevier B.V., 2002-01-01)
Angiotensin II (AngII) and bradykinin (BK) derivatives containing the TOAC (2,2,6,6-tetramethylpiperidine-N-oxyl-4-amino-4-carboxylic acid) spin label were synthesized by solid phase methodology. Ammonium hydroxide (pH 10, ...

Observations from secondary school classrooms in Trinidad and Tobago: Science teachers’ use of analogies
(International Council of Associations for Science Education (ICASE)., 2015-12)
This study sought to examine and interpret how science teachers in Trinidad and Tobago used analogies in their science teaching. A total of 30 lessons taught by five different teachers were observed and analysed, using an ...
Overall Similarity Overrides Element Similarity when Evaluating the Quality of Analogies
(Seoul National University. Institute for Cognitive Science, 2013-09)
Dominant computational models of analogical reasoning (e.g., SME, ACME and LISA) consider that two facts or situations are more analogous as the similarity between corresponding propositional elements increases. We report ...
Promoting interdomain analogical transfer: When creating a problem helps to solve a problem
(Springer, 2017-02)
Research on analogical thinking has devised several ways of promoting an abstract encoding of base analogs, thus rendering them more retrievable during later encounters with similar situations lacking surface similarities. ...
A current-mode based Field-Programmable Analog Array for signal processing applications
(Kluwer Academic Publ, 1998-09-01)
This paper presents a new approach to develop Field Programmable Analog Arrays (FPAAs),(1) which avoids excessive number of programming elements in the signal path, thus enhancing the performance. The paper also introduces ...
Active Current Mirrors for Low-Voltage Analog Circuit Design
(Birkhauser Boston Inc, 2017-12)
In this work, active current mirrors using sensing resistors and a pass transistor in a feedback loop will be examined in detail. First, several non-idealities in this family of circuits, such as offset, noise, output ...
An inductor-free realization of the Chua`s circuit based on electronic analogy
(SPRINGER, 2009)
Although literature presents several alternatives, an approach based on the electronic analogy was still not considered for the implementation of an inductor-free realization of the double scroll Chua`s circuit. This paper ...
