Have the southernmost Andes been curved since Late Cretaceous time? An analog test for the Patagonian Orocline
(Geological Society of America, 2007-01)
The kinematic evolution of the enigmatic arc-shaped southernmost Andes of Patagonia and Tierra del Fuego has been a subject of debate for most of the past century. We compared the results from analog sandbox experiments ...
Activity of the pterophyllins 2 and 4 against postharvest fruit pathogenic fungi. Comparison with a synthetic analog and related intermediates
(Elsevier Science, 2018-03)
The antifungal activity of pterophyllin 2, pterophyllin 4, a 5-desmethyl analog of the latter and some of their synthetic intermediates, against three postharvest phytopathogenic fungi, was evaluated. The target fungi were ...
Testing an ethnographic analogy through geometric morphometrics: A comparison between ethnographic arrows and archaeological projectile points from Late Holocene Fuego-Patagonia
(Academic Press Inc Elsevier Science, 2018-09)
Under certain conditions, ethnographic analogies can help to shed light on past behaviors registered in the archaeological record via observation and model-building from modern societies. In this context, ethnographic ...
Inverse method for the analysis of instrumented impact tests of polymers
Impact testing has become an important technique to determine the parameters associated with dynamic fracture of polymeric materials. These parameters are commonly calculated from the experimentally measured load versus ...
Synthesis and classical pathway Complement inhibitory activity of C7-functionalized filifolinol derivatives, inspired in K-76 COOH
(Elsevier France-editions Scientifiques Medicales Elsevier, 2012-09)
A series of carboxylic acids carrying various functionalization on C-7 of their common 3H-spiro[benzofuran-2,1?-cyclohexane] skeleton were synthesized from filifolinol, as analogs of the natural Complement inhibitor K76-COOH. ...

(Centro Interamericano de Investigaciones Psicológicas y Ciencias Afines, 2011-06)
Se describen las bases conceptuales y operacionales de los tests de resolución de problemas por analogía estableciendo énfasis en las analogías de figuras. Se expone brevemente la importancia del estudio de dicho constructo ...
ANALOGIES AND TEACHING TASKS IN LAWS OF CONSERVATION IN TENTH GRADE, DIAGNOSIS AND PERSPECTIVESANALOGÍAS Y TAREAS DOCENTES EN LEYES DE CONSERVACIÓN EN DÉCIMO GRADO: DIAGNÓSTICO Y PERSPECTIVAS
(Universidad Central "Marta Abreu" de Las Villas, 2017)
Synthesis and Evaluation of New Halogenated GR24 Analogs as Germination Promotors for Orobanche cumana
(Frontiers Media S.A., 2021-09)
Orobanche and Striga are parasitic weeds extremely well adapted to the life cycle of their host plants. They cannot be eliminated by conventional weed control methods. Suicidal germination induced by strigolactones (SLs) ...
Interaction of acylated and substituted antimicrobial peptide analogs with phospholipid-polydiacetylene vesicles. Correlation with their biological properties
(Wiley Blackwell Publishing, Inc, 2011-07)
A series of peptide analogs based on region 6-22 of Plantaricin 149 sequence were synthesized. The interaction between these analogs and phospholipid-polydiacetylene vesicles was investigated to evaluate the ability of the ...
Design, synthesis and cytotoxic evaluation of peptoid analogs of an anticancer active triazolylpeptidyl penicillin
(Future Medicine Ltd., 2021-05)
Aim: Encouraged by the antitumor activity exhibited by triazolylpeptidyl penicillins, we decided to synthesize and evaluate a library of peptoid analogs. Results: The replacement of the dipeptide unit of the reference ...
