Abstract in GermanDer folgende Beitrag veranschaulicht bedeutende kulturelle Entwicklungen in der Litauischen SSR der Stalin- und der Chruščev-Ära, die gleichsam deutlich machen, dass die Sowjetisierung in einem Wechselverhältnis mit der litauischen Nationsbildung stand. Mit dem Fokus auf herausragende Kulturfunktionäre demonstriert der Aufsatz den Ausbau der Kulturstrukturen, die Mobilisierung loAbstract in PolishCelem badania było wykazanie napiętego stosunku między procesami sowietyzacji i tworzenia się litewskiego narodu. Do ich zobrazowania wybrałam kulturowy rozwój scenicznego folkloru i kina, które skupiały się wokół wybitnych funkcjonariuszy kultury epoki Stalina i Chruszczowa. Za pomocą instytucjonalizacji, mobilizacji elity, jak i konkretnej pracy funkcjonariuszy przedstawiono, w

In the 1960s, Soviet Lithuania witnessed the rise of an intensied interest in paganism. Aiming to diminish the infuence of the Roman Catholic Church, the Communist Party promoted Lithuanian pre-Christian customs and rituals that, in turn, not only became a successful instrument against Catholicism but also an effective stimulus of nationalism. Arising within the framework of academic touristic cl

Objectives: The credit market has expanded rapidly, increasing the risk of over-indebtedness among those who lack secure employment or adequate income, an issue of concern in the COVID-19 aftermath. We investigated the role of over-indebtedness for developing poor mental health, and whether this impact is modified by age, gender, educational level or being in precarious employment.Methods: This isOBJECTIVES: The credit market has expanded rapidly, increasing the risk of over-indebtedness among those who lack secure employment or adequate income, an issue of concern in the COVID-19 aftermath.

In this paper, the most important results are presented and discussed from a multiyear interdisciplinary study directed toward the identification of the most suitable glass/polymer composite systems with the highest resistance to brittle fracture for high voltage composite insulator applications. Several unidirectional glass/polymer composite systems, commonly used in composite insulators, based e

An improved version of a brittle fracture model based on the formation of nitric acid in service through corona discharges, ozone, and moisture, is presented and used to explain different modes of brittle fracture. Throughout the work, the insulators are referred to as nonceramic insulators (NCIs). The information given is expected to help the insulator manufacturers and users design, manufacture,

The applicability of using flat composite plates and hollow core composite cylinders for moisture absorption testing of unidirectional glass/polymer composites used in high voltage composite (non-ceramic) insulators was examined. Two main issues were addressed in this work. First, the effect of specimen geometry (cylinders vs. plates) on moisture absorption by the composites was investigated both

The chemical environment responsible for the brittle fracture failure of composite (non-ceramic) insulators is determined. Also previously reported observations by the authors are verified. Five non-ceramic composite suspension insulators and one composite guide were subjected to FTIR analysis. Out of the six field failed units, five insulators showed significant levels of nitrate on their brittle

It was postulated in [1], based on experimental evidence, that brittle fracture failures of composite (non-ceramic) HV insulators could be caused by water and mechanical stresses. It was also claimed therein that the brittle fracture process was more likely to happen with water than acids. This postulation could be of major importance as its ramifications might affect the entire composite insulato

This paper describes water diffusion into and electrical testing of unidirectional glass reinforced polymer (GRP) composite rods used as load bearing components in high voltage composite (non-ceramic) insulators. The tests were performed following ANSI standard C29.11 Section 7.4.2 that can be used to evaluate electrical properties of composites. The unidirectional composite rod materials based on

Moisture absorption tests were performed on unidirectional glass/polymer composite materials used in high voltage composite (non-ceramic) insulators. The composites were based on E-glass, high seed count ECR-glass and low seed count ECR-glass fibers with modified polyester, epoxy and vinyl ester resins. The composites were exposed to a moist environment with a relative humidity of 80% at 50 °C, an

Unidirectional and woven graphite fiber (T650-35)/polyimide (PMR-15) composites with embedded aluminum inclusions were investigated for their aging behavior either in nitrogen or air at 315 °C for up to 1170 h. Residual strains and stresses in the inclusions were determined as a function of aging by performing X-ray diffraction (XRD) measurements. Subsequently, residual strains and stresses in the

Existing brittle fracture models have been reviewed and their applicability to explain the in-service brittle fracture failure of composite (non-ceramic) insulators is evaluated. It is shown that the only brittle fracture model that can explain all aspects of the brittle fracture process is a model based on the formation of nitric acid solutions in-service. The chemical cause of brittle fracture i

The effect of large bending loads on strains and stresses inside aluminum particles embedded in unidirectional and woven eight harness satin (8HS) graphite/PMR-15 composites has been examined. The stresses and strains in the particles were determined by performing X-ray diffraction (XRD) measurements. It has been shown in this work that when the composites are subjected to large four-point bending

Iosipescu shear tests were performed at room temperature and at 316-°C (600-°F) on woven composites with either M40J or M60J graphite fibers and PMR-II-50 polyimide resin matrix. The composites were tested as supplied and after thermo-cycling, with the thermo-cycled composites being tested under dry and wet conditions. Acoustic emission (AE) was monitored during the room and high temperature Iosip

This work evaluates the effects of static and cyclic loading conditions on the stress corrosion process in unidirectional glass/modified polyester composite in the presence of a nitric acid solution. The composites were investigated under static, cyclic, and static with overload conditions using a rectangular specimen with centrally positioned grooves. The stress corrosion process was monitored us

Stress corrosion experiments were performed on unidirectional ECR-glass/polymer composites with the modified polyester, epoxy and vinyl ester resins for the use in high voltage composite insulator applications. Two types of ECR-glass fibers were investigated with low and high counts of gaseous inclusions (seeds) within the glass. The stress corrosion tests were performed in nitric acid under four

Failure and stiffness properties of a woven 8 harness satin (8HS) graphite/PMR-15 composite have been investigated at room temperature and at 315°C by performing the ±45° tensile and Iosipescu tests. Acoustic emission has been monitored during testing. The critical loads for the initiation of damage in the composite have been determined. In particular, the specimen width effect has been investigat

The purpose of this research is to examine the effect of sandblasting on the initiation of stress corrosion cracking (SCC) in unidirectional E-glass/polymer composite materials with modified polyester, epoxy and vinyl ester resins. The composites with different amounts of surface damage due to sandblasting have been subjected to mechanical bending loads in the presence of nitric acid (pH=1.2). It
