hrv Life Extension projekt u kontekstu Luhmannove sistemske sociokibernetike
eng The Life Extension Project in the Context of Luhmann’s Sociocybernetics
ger Das Life-Extension-Projekt im Kontext von Luhmanns Systemtheorie der Soziokybernetik
Dević, Mislav
Socijalna ekologija Vol. 22, No. 1, 2013
Rad tematizira life extension projekt sa stajališta Luhmannove sistemske sociokibernetike. Problematika produljenja ljudskog života u opsežnom Luhmannovu opusu ostala je gotovo nedotaknuta. Stoga se u prvoj tematskoj cjelini rada sistematiziraju relevantne teorijske postavke za razradu ove u biološkoj, medicinskoj a u novije vrijeme i sociološkoj literaturi sve prisutnije tematike. Ukazuje se na značajne posebnosti koje sistemskoteorijski pristup life extension projektu donosi u odnosu na pristup istoj problematici sa stajališta drugih teorijsk...

eng Proposition for different life hazard curve for transformer and substation equipment
Grisaru, Marius
Transformers Magazine Vol. 6, No. 5, 2019
Today the classical bathtub curve model is the main model for life expectancy calculation of all the electrical equipment and, especially, all kind of oil-filled transformers. Most of the stakeholders and maintenance engineers make their decisions on tests, treatments and most importantly, replacement, on the bathtub curve concept. The costs that are associated with the classical bathtub curve are substantial, mainly driven by the unnecessary treatment or unnecessary replacements.

eng Power Transformer Life
Gamez, Carlos
Transformers Magazine Vol. 1, No. 1, 2014
The concept of life for an electrical asset, such as a power transformer, is sometimes not properly understood. In this article, the frst from the series of three articles, we review what we mean when we refer to the “life” of a transformer and what constrains determine the design and operational parameters of these assets.

eng What’s behind transformer field testing?
Tabernero García, Andrés
Transformers Magazine Vol. 2, No. 3, 2015
To prevent unexpected outages it is necessary to implement a field test programme. It has to be decided what tests should be performed and what information is expected to be obtained from these tests. This paper describes a common set of field tests on the basis of prescribed standards and years of field experience. Offline and on-line tests are described as well as their use in diagnosis and trending. The paper also highlights the importance of training in this process to make conclusions and recommendations reliable.

eng Power transformer life Part 3: Life management and extension
Gamez, Carlos
Transformers Magazine Vol. 1, No. 3, 2014
This article closes the Transformer Life series by looking at various ways that a transformer owner can extend the life of their investment. From the initial stages of specifying and purchasing a transformer to the management of the transformer throughout its useful life, we explore which options have the best cost to beneft ratio and why.

eng Power transformer Life Part 2: Ageing Mechanisms
Gamez, Carlos
Transformers Magazine Vol. 1, No. 2, 2014
This article continues to explore the concepts described in the previous article where a link between insulation life and overall transformer life was established. Through the examination of the molecular structure of cellulose, the main constituent of most of the insulation system, it explains the various factors that might affect the integrity of this component, how they contribute to the normal ageing processes and how these processes are sometimes accelerated. After we have established a link between the life of a transformer and the life...

eng New method for 2-furfuraldehyde analysis
Remartinez, Begoña; Jiménez, Javier
Transformers Magazine Vol. 2, No. 2, 2015
Apart from abnormal faults detected by DGA, one of the most important factors in shortening the lifetime of a power transformer is ageing of paper insulation used in transformer construction. The analysis of furans in transformer oil is one of the best techniques to be used in the assessment of the remaining lifespan of a used transformer. This technical article aims to describe the development and validation of an analytical method based on ultraviolet-visible (UV-VIS) absorption spectrophotometry, designed to evaluate the content of 2-furfura...

hrv Izazovi produljenja ljudskoga života na razmeđu poboljšanja i agonije
eng The Challenges in Human Life Extension Between Enhancement and Agony
Singbo, Odilon-Gbènoukpo; Gložinić, Terezija; Čartolovni, Anto
Diacovensia Vol. 28, No. 3, 2020
Ovaj rad nastoji prikazati dva načina produljenja ljudskoga života. S jedne strane nalazi se distanazija, tj. terapijska upornost oko produženja života teškoga bolesnika, a s druge strane transhumanizam kao filozofski pravac koji u svojoj srži teži bezgraničnom produžavanju ljudskoga života s temeljnom željom za eliminiranjem bolesti, starenja i smrti. Povezujući ih s medicinskom praksom, rad pokazuje implikacije u kliničkoj praksi te nastoji upozoriti na etička i antropološka pitanja o produžavanju života.

hrv Trend kretanja cjeloživotnog obrazovanja i učenja kao preduvjet stvaranja društva znanja
eng Trend of lifelong education and learning as a prerequisite for creating knowledge society
Pauković, Maja; Bačić, Lucija
Zadnjih nekoliko godina svjedoci smo znatnog povećanja demografskog starenja stanovništva. Tržište rada, koje je iznimno promjenjivo i dinamično, selektira radno aktivne osobe po stupnju stručne spreme i vještinama koje su, bilo formalnim ili neformalnim oblikom obrazovanja, stekli tijekom života.Tako cjeloživotno obrazovanje i učenje postaje najjače oruđe za osobni i profesionalni rast i razvoj što omogućava veću mobilnost i zapošljavanje. Obrazovanje odraslih i cjeloživotno učenje prioritetna je zadaća stvaranja društva znanja i održivog razv...
