Cosmopolitan Memories under Pressure : The Case of Postcommunist Wrocław
This article uses the Polish case of Wrocław (formerly Breslau), a city burdened by memories of war and forced displacement, to show the dynamics between hegemonic memories, dominant memories and countermemories. After the fall of communism, the city changed the previous nationalist-communist narrative of its past by institutionalizing a new official narrative that promotes cosmopolitan memory. Th

In 2019 Olga Tokarczuk, an outstanding Polish writer received Nobel Prize in literature. The prize appeared as a culmination of her growing popularity outside Poland, including Sweden. In our article we attempt to trace Tokarczuk´s pathway to Nobel Prize, through studying her reception in Sweden. Already in 2005 the first translations of her books appeared in Sweden, with enthusiastic reviews. Her

The Cult of the Balts : Mythological lmpulses and Neo-Pagan Practices in the touristic Clubs of the LSSR in the 1960s and 1970s
In the 1960s, Soviet Lithuania witnessed the rise of an intensied 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
Selling one's future : over-indebtedness and the risk of poor mental health and the role of precarious employment - results from the Scania Public Health Cohort, Sweden
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.

Can water cause brittle fracture failures of non-ceramic insulators in the absence of electric field
Resistance to brittle fracture of glass reinforced polymer composites used in composite (nonceramic) insulators
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
Failure analyses of nonceramic insulators : Part II - The brittle fracture model and failure prevention
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,
An investigation of moisture and leakage currents in GRP composite hollow cylinders
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
FTIR analysis of non-ceramic composite insulators
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
Can water cause brittle fracture failures of composite non-ceramic insulators in the absence of electric fields?
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
Water diffusion into and electrical testing of composite insulator GRP rods
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 properties of unidirectional glass/polymer composites used in composite (non-ceramic) insulators
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
X-ray diffraction experiments on aged graphite fiber/polyimide composites with embedded aluminum inclusions
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
Causes and potential remedies of brittle fracture failure of composite (non-ceramic) insulators
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
Analysis of stresses in aluminum particles embedded inside unidirectional and woven graphite/polyimide composites subjected to large bending loads
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
In-plane shear testing of medium and high modulus woven graphite fiber reinforced/polyimide composites
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
