After a short description of the PECVD reactors main layers and their application such as silicon oxide, TEOS, silicon nitride, silicon oxynitride, silicon carbide, amorphous silicon, diamond like carbon are presented. The influence of the process parameters such as: chamber pressure, substrate temperature, mass flow rate, RF Power and RF Power mode on deposition rate, film thickness uniformity, refractive index uniformity and film stress were analysed. The main challenge of thin films PECVD deposition for Microelectromechanical Systems (MEMS)and semiconductor devices is to optimize the deposition parameters for high deposition rate with low film stress which and if is possible at low deposition temperature.","PeriodicalId":32445,"journal":{"name":"Annals Series on History and Archaeology Academy of Romanian Scientists","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78053266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From an economic perspective, both theorists in Transylvania and Romania were fostering the idea of a liberal “Ourselves alone” doctrine after 1900. Economic policies were established based on the resolutions adopted following the proceedings of the Economic Congresses in Iași, between 1882 and 1884. Fundamental assumptions were derived from banking and financial arguments based on the numerous and meaningful business relationships established between the National Bank of Romania and the Solidaritatea Banking Union in Sibiu, comprising almost all the Romanian banks in Transylvania.","PeriodicalId":32445,"journal":{"name":"Annals Series on History and Archaeology Academy of Romanian Scientists","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84817975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are four main pillars that characterized the life of the people here: the constancy of living, also proven by the practice of agriculture; the foundation of the Orthodox faith; the fight for the defense of the lands inherited from the ancestors for centuries; and the economic valorization of the strategic location at the intersection of the roads connecting the four Romanian provinces.

{"title":"A LITTLE-KNOWN DOCUMENT ON THE LIFE AND FORMATION OF TUDOR VLADIMIRESCU","authors":"Radu Ştefan Vergatti","doi":"10.56082/annalsarscihist.2021.1.15","DOIUrl":"https://doi.org/10.56082/annalsarscihist.2021.1.15","url":null,"abstract":"This year, 2021, marks the 200th anniversary of the revolution led by Tudor Vladimirescu. It also commemorates two centuries since his assassination. To evoke the formation of Tudor Vladimirescu, I used a little-known document - the moral testament of the master (jupan) Gheorghe Duncea. The act is important because he knew the bailiff Tudor Vladimirescu throughout his life, from childhood to death. This document specified the year of Tudor's birth, the place of birth, the way he learned to read and write, his connection with Horia from Albac, the leader of the Transylvanian peasant uprising of 1784, the reception of the first small boyars ranks, his training as a soldier in the Russian army during the Russo-Turkish war between 1806-1812. Then the Russian generals appreciated him, and the tsar decorated him with the Order of St. Vladimir, gave him a ring and promoted him to the military rank of lieutenant (parucic). After the war, between June and December 1814 he went to Vienna to solve the affairs of the late Elenco Glogoveanu. Then he met the atmosphere of the capital of the Habsburg Empire. His main goal was to fight for the removal of the Greeks from the leadership of Wallachia and eventually Moldova. He arrived in Bucharest again in November 1820. Then he contacted the great boyars who ruled the country. The Greek hospodar of Wallachia Alexandru Suţu was old and ill. On January 15/27, 1821, Alexandru Suţu died. Three of the great boyars, members of the Filiki Eteria, Grigore Brâncoveanu, Ghica, Văcărescu, asked him to start the revolution in Oltenia. Tudor Vladimirescu had been trained for a long time. He left for the north of Oltenia and in four days he reached the great Tismana monastery. From there he summoned his paramilitary force, the Pandurs, and called the people to battle. This is where I must end my communication. There remains only one point that Gheorghe Duncea's will clarifies. He recorded what his nephew, his son-in-law, Captain Bosoancă, told him. He said that being disguised, he went to see what was happening to Tudor Vladimirescu. This is how he saw that Tudor Vladimirescu was seized by a group of the Eteria and taken to the outskirts of Târgoviște. There he was tortured and killed, his stomach was split with a javelin, then ripped out with a suction cup. In memory of the great hero of the Romanian people, a beautiful stone monument was erected on the field from Padeş after the project of the architect State Baloşin.","PeriodicalId":32445,"journal":{"name":"Annals Series on History and Archaeology Academy of Romanian Scientists","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80695757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
