Thermomechanical Properties of Radiation-Modified Polyethylene/Ethylene-Propylene-Diene Copolymer/Liquid-Crystalline Copolyester Blends
1999
Radiation-modified blends of high-density polyethylene (PE) with ethylene-propylene-diene copolymer (EPDM; 10-65 wt.%) and thermotropic liquid-crystalline polymer (LCP; 10 wt.%) were investigated. The LCP was a liquid-crystalline copolyester of 40% poly(ethylene terephthalate) with 60% 4-hydroxybenzoic acid. The constituents were blended using a circular extruder, the specimens were prepared by compression molding and irradiated by 60Co γ-radiation up to 200 kGy. Mechanical, thermal, and morphological properties in wide temperature range were investigated for the irradiated and non-irradiated specimens. The effects of irradiation on the thermomechanical behaviour of the PE matrix are discus…
Research of the physical-chemical properties of adhesive radiation-modified thermosetting materials based on polyolefins and their composites
1999
The present paper surveys the investigation results of the adhesive behavior with steel of different polyethylenes (LDPE, HDPE) irradiated with γ-radiation in vacuum, oxygen, and air, using rheological, optical, thermomechanical and other methods. To study the adhesive contact, the technological parameters applicable to thermosetting polymer material were taken into consideration. The results show the suitable methods in order to obtain thermosetting polymer materials with improved adhesive and thermomechanical properties.
Reproductive Dysfunction in Classical and Nonclassical Congenital Adrenal Hyperplasia Due to 21-Hydroxylase Deficiency
2021
Patients with congenital adrenal hyperplasia (CAH) both with severe (classical CAH) and mild (nonclassical NCAH) forms exhibit a wide spectrum of reproductive dysfunction. In this review, only CAH cases with 21-hydroxylase deficiency (21-OHd) will be discussed, as they represent almost all of the patients in reproductive clinical settings.
Understanding Consumers’ Online Shopping Behavior during the Covid-19 Pandemic – Empirical Research
2020
The COVID-19 pandemic has impacted our daily behavior, from interactions with friends, colleagues, and family, to safety measures and working. Additionally, this pandemic has dramatically changed consumers’ shopping behavior. The purpose of this research paper is to examine the impact of Covid-19 pandemic on consumer behavior. Thus, this paper proposes a new model that incorporates three variables: attitude for online shopping during the COVID-19 pandemic, budget considerations during the COVID-19 pandemic, and future behavioral intention after the COVID-19 pandemic. This study’s main research approach is a quantitative survey and examination using a sample of Romanian consumers. Additional…
Does time spent on device security and privacy inhibit online expression?
2019
Freedom of expression is a recognized human right. More recently, the UN has resolved that unrestricted access to the Internet is also a human right. A commonly accepted benefit of the Internet is that it serves as a platform for free expression. Usage of the Internet for free expression can be a way of circumventing censorship or other hindrances that prevent citizens' freedom of expression in more traditional publishing media. However, the Internet has unique security and privacy risks that may affect users' attitudes toward expressing themselves online. In the online environment, users with controversial viewpoints may be reluctant to express the viewpoints due to concern about possible …
Baltkrievijas 2020. gada prezidentālās vēlēšanas - atainojums Krievijas medijos
2021
Pētnieciskā darba nosaukums ir: “Baltkrievijas 2020. gada prezidentālās vēlēšanas – atainojums Krievijas mediju dienaskārtībā”. Pētījuma ietvaros izvirzītie mērķi ir sekojoši – 1) izpētīt, kā tika atainotas Baltkrievijas prezidentālās vēlēšanas un ar to saistītie notikumi Krievijas medijos 2020. gada augusta, septembra, oktobra mēnešos; 2) izpētīt Krievijas Federācijas sabiedrības attieksmi par Baltkrievijas prezidentālām vēlēšanām un ar vēlēšanām saistītiem notikumiem. Empīriskie dati pētījumā tika iegūti izmantojot kvalitatīvu kontenta analīzi, sabiedriskās domas aptauju un padziļināto interviju analīzi. Pētījuma rezultātā tika izsecināts, ka Krievijas mediju dienaskārtība ietekmēja Kriev…
Comparing SARS-CoV-2 case rates between pupils, teachers and the general population: results from Germany
2021
Given the inconsistent state of research regarding the role of pupils and teachers during the SARS-CoV-2 pandemic in Germany, statewide and nationwide data of infection case rates were analyzed to contribute to the discourse. Infection data from official sources ranging from mid to late 2020 were collected, prepared and analyzed to answer the question if pupils, teachers and general population differ in infection case rates or not. Statewide and nationwide data showed that pupils and teachers infection case rates exceeded those of the general population. However, present data do not necessarily indicate that SARS-CoV-2 cases of pupils and teachers infections took place at schools. Actually,…
Essere fuori luogo. Appunti di clinica della migrazione
2005
Viene analizzato il vissuto del migrante proveniente da altri luoghi e altre culture nell'impatto con la società occidentale. In particolare si analizzano gli aspetti legati all'integrazione, i conflitti esistenti tra il mondo originario e il luogo di accoglienza e la condizione che lascia il migrante sospeso tra il paese che lo accoglie e quanto di reale, simbolico o mitico egli porta con sé
Puheen ymmärtämisen tehtävien taitotasoille asettaminen Yleisissä kielitutkinnoissa
2016
The aim of this study is to explore rater effects, such as consistency and severity of the judgements of 12 expert judges, and to report the extent of assessment criteria used by them. The data of the study are based on the three different phases of the standardization procedure which were analyzed using the MFRM model. In addition, feedback gathered from the expert judges was used to find out their opinions about the procedure and to validate the results of the standardization. The results of this study indicate that general discussion on and statistical information about the items influenced judges’ consistency and severity and their adaptation of the assessment criteria. The judges thems…
