Structural changes of selected materials for glass industry after thermal loading

The presented paper is focused on study and investigation of structural changes in relation to the selected materials which are exposed to the thermal loading. The given work is connected with closer investigation of such material as Dominial ZF 2 which is commonly used for production of steel moulds and components in the glass industry. Moreover, the given work is also devoted to the investigation of materials which are commercially called Toolox 33 and Toolox 44 because these materials were proposed by firm to be used as substitutive materials of Dominial ZF 2. Both of the mentioned and investigated materials have not been used in glass industry yet. Experimental procedures were proposed on the basis of the fact that the investigated materials are exposed to thermal as well as mechanical loading and they are in direct interaction with hot molten glass. After simulated thermal loading, the investigated materials were exposed to the static tensile test and by this way, it was possible to obtain samples with fracture surfaces and these fracture surfaces were evaluated in terms of characteristic features relating to rupture. On the basis of the obtained results and knowledge from experimental procedures, Toolox 33 and Toolox 44 are not recommended to be used for production of steel moulds and components for glass products.

Circular Dichroïsm

The Streptococcus pyogenes Cas9 protein (SpCas9), a component of CRISPR-based immune system in microbes, has become commonly utilized for genome editing. This nuclease forms a ribonucleoprotein (RNP) complex with guide RNA (gRNA) which induces Cas9 structural changes and triggers its cleavage activity. Here, electronic circular dichroism (ECD) spectroscopy was used to confirm the RNP formation and to determine its individual components. The ECD spectra had characteristic features differentiating Cas9 and gRNA, the former showed a negative/positive profile with maxima located at 221, 209 and 196 nm, while the latter revealed positive/negative/positive/negative pattern with bands observed at 266, 242, 222 and 209 nm, respectively. For the first time, the experimental ECD spectrum of the gRNA:Cas9 RNP complex is presented. It exhibits a bisignate positive/negative ECD couplet with maxima at 273 and 235 nm, and it differs significantly from individual spectrum of each RNP components. Additionally, the Cas9 protein and RNP complex retained biological activity after ECD measurements and they were able to bind and cleave DNA in vitro. Hence, we conclude that ECD spectroscopy can be considered as a quick and non-destructive method of monitoring conformational changes of the Cas9 protein as a result of Cas9 and gRNA interaction, and identification of the gRNA:Cas9 RNP complex.

Solid System

The article attempts to examine the characteristic features of kinship terms in Armenian, English and Russian. Kinship terms make up a solid system with closely interconnected constituents. Kinship terms, which can be found in all languages, act as universalities. However, being universalities kinship terms may be different in different languages in terms of ethnolinguistic salience. The existence of certain kinship terms in a given language is, of course, connected with the kinship relations existing in the given society. Language affects the world perception of the language bearers. It reflects the notions and phenomena that are of prime importance for the speakers of the given language.

Float Process

My subject is the float process for making flat glass. I would like, first of all, to put the float process into perspective by describing briefly, and in simple terms, the methods used for making flat glass before and at the time of the invention of the float process and then to describe the development of the process itself and the position it occupies in the flat glass industry today. Finally, I would like to describe in as much depth as time allows, three of the main problems which had to be tackled in developing this process. The Egyptians seem to have been the first people to realize what could be done with glass when it is hot and plastic, and they made vessels for cosmetics and perfumes by, it is assumed, trailing molten glass around a shaped core. By Roman times glass was being blown and moulded, cut and engraved, painted and gilded, and the Romans had mastered the plastic character of heat softened glass so fundamental to today’s processes.

Abstract In this study, fracture behavior and strength in the flat braided bar with a circular hole were investigated by static and fatigue test. Two type of specimens were prepared. They are a braided flat bar with an integrally-formed braided hole and a braided flat bar with a machined hole. Moreover, we also examined a specimen that had a metal pin inserted at the circular hole. This specimen was subjected to a static tensile test. The results of the tensile tests indicate that the strength of the flat bar with a braided hole was larger than that of the one with the machined hole. Furthermore, from the results of the fatigue tests, the flat bar with the braided hole showed higher fatigue property than that of the one with the machined hole.
