Rezumat

For the first time thick (~ 8 μm) Cu/Co-W multilayered coatings with individual layers ranging from 5 to 200 nm were electrodeposited from a single bath. The content of tungsten in rich-in Co-W layers was controlled by varying current densities in a citrate-borate bath. Continuous Multi-Cycle (CMC) nanoindentation technique was used to analyze mechanical properties of those deposits. Optical examination of the indented zone revealed the absence of cracks inside and outside the indentation area in the interval of the normal loads used. The hardness of Cu/Co-W multilayers varied with the bi-layer period and the electrodeposition parameters. The Cu/Co-W multilayers showed an increased hardness compared to that of Co-W coatings electrodeposited under the same conditions.

<description xml:lang='ro' descriptionType='Abstract'>În cadrul nunţii, în timpul dezbrăcării miresei de vestimentaţia rituală şi îmbrăcării ei în cea de femeie căsătorită sunt interpretate două categorii de cântece: melodii rituale consacrate de-a lungul veacurilor şi melodii ritualizate, adaptate în calitate de Cântecul miresei. În lucrare este analizat repertoriul şi specificul melodiilor ritualizate. Autoarea motivează readaptarea acestor melodii
prin concursul mai multor factori de ordin psihologic şi social-istoric.</description>
<description xml:lang='en' descriptionType='Abstract'>Processus courants visant la fonctionnalité de la chanson de la jeune mariée dans la noce bessarabienne (Svetlana Badrajan).
Au cours de la noce, le déshabillage de la jeune mariée des vêtements rituels et son habillage en vêtements de femme mariée sont accompagnés de deux catégories de chansons:
mélodies rituelles consacrées tout au long des siècles et mélodies ritualisées qui ont été adaptées plus tard à cette qualité. Dans le présent ouvrage on analyse le répertoire et les particularités de la deuxième catégorie – les mélodies ritualisées. L’auteur met plusieurs facteurs d’ordre
psychologique et socio-historique à la base de la réadaptation de ces mélodies.</description>
