Shear Modification of Polyolefines and its Integration in Polymer Processing
Authors: Ritzau G. 
Published: April 2022

Abstract
The viscous and especially the elastic properties of polymer melts can be altered by a previously imposed deformation history. This phenomenon, usually termed as shear modification, is caused by the reversible physical disentanglement of the polymer molecule chains. The shearing unit presented in this paper was used to systematically investigate the processing parameters governing shear modification.
A set of rheological tests was carried out with the shear modified sample material and the expected changes in the rheological behaviour were detected. The relative change of the storage modulus G’, measured using a Rheometrics On-line Rheometer system, was taken as a measure for the degree of modification and was found to correlate with the specific energy dissipated during sample preparation. The effects of shear modification on product properties were investigated for the tubular film-blowing process. Changes in the optical and mechanical properties of films which can be attributed to the previously imposed shear modification process were found.
On the toponymics of the Great Palace of Constantinople: the Daphne
Authors: Calahorra Bartolomé Alfredo 
Published: April 2022

Abstract
The Great Palace of Constantinople has been subject to several investigations since the second half of the nineteenth century. All of them have been mostly concerned with the topographical, architectural and typological development of the imperial residence, leaving aside questions such as toponymics. This paper will deal with this issue taking into consideration the name of the complex of buildings that once was the core of the Constantinian Palace, the Daphne. Doing so, we will better understand the denomination of the Palace, and shed light on the functions related to several spaces, the courtly ritual and, in short, the representation of power through architecture in an imperial context. Besides, the present enquiry will challenge some topographical assumptions on the complex.
Late Byzantine sigillographic evidence from Cappadocia: lead seals from Kırşehir with a unique overstruck example
Authors: Laflı Ergün , Cheynet Jean-Claude 
Published: April 2022

Abstract
This short essay presents four 11th century A.D. Byzantine lead seals, all of which are stored in the local museum of Kırşehir, in ancient Cappadocia, which is located today in southeastern part of central Turkey. The Museum of Kırşehir owns a minor collection of at least 13 Byzantine lead seals and a selection of four unpublished seals is being presented, which were sold to the museum by local antique dealers from the Turkish provinces of Kırşehir and Aksaray. All of the seals are dated to the late 10th and early or mid-11th centuries A.D. No. 1 is an overstruck seal with a parallel piece which is a very unique specimen and raises some sigillographic and prosopographic questions. The three other seals are discussed with a focus to Byzantine dignitaries and their offices during the 11th century A.D. The descriptive discussion at the beginning briefly touches upon a some geographical and historical issues related to Kırşehir and its museum. This small collection of seals provides important evidence regarding the seal owners and the administration of the themes of Cappadocia and Charsianon on the eastern border of the Byzantine Empire. The paper offers a substantive analysis of the material, with a discussion and resolution of the sigillographic inscriptions and imagery.

The influence of oiled fiber, freeze-thawing cycle, and sulfate attack on strain hardening cement-based composites
Authors: Gao Song , Ban Shunli , Wang Hao , Lei Dongyi , Gong Yaoyao 
Published: April 2022

Abstract
The interfacial transition zone (ITZ) between the fiber and the matrix significantly influences the strengthening and toughening effect of the fiber for the matrix. The ITZ between the fiber and mortar is a weak link in strain hardening cementitious composites (SHCC), the loose structure is easily damaged, and it is the main channel of ion attack. The oil reduces the hydrophilicity of fiber and the bonding strength of fiber and mortar, which decreases flexural and compressive strengths, but increases the tensile ductility. The compressive strength increased with the increase in the microhardness of ITZ. Both freeze-thawing cycle and sulfate attack reduce the flexural and compressive strengths, and ductility of SHCC. The failure of ITZ is responsible for the performance decrease. The strength of the samples containing oiled fiber after the freeze-thawing cycle and sulfate attack decreases more significantly.

Authors: Novikov Oleg 
Published: April 2022

The article is devoted to the study of the correlation between reported traffic accidents, road traffic administrative offenses and criminal offenses against road safety and transport operation in Ukraine for 2015-2020. The author found that road traffic administrative offenses should include Art. 121, 121-2, 122, 123, 124, 125, 126, 127, 128, 128-1, 129, 130, 133-1, 139 and 140 of the Code of Ukraine on Administrative Offenses, and on criminal offenses against road safety and operation of transport - Art. 280, 286, 286-1, 287 and 291 of the Criminal Code of Ukraine. It is proved, that the statistical ratio between road traffic administrative offenses and criminal offenses against road safety and transport operation increased significantly annually from 2015 to 2020 (from 71:1 to 344:1). The average ratio of administrative offenses and criminal offenses in Ukraine for six years (2015-2020) was 209:1, and for four years (2017-2020) - 274:1. The obtained data on Ukraine are interesting from the point of view of their inconsistency with the general tendencies of the ratio of administrative offenses and criminal offenses. After all, the increase in the number of detected administrative offenses should indicate an improvement in the work of the patrol police in the field of road safety and, in turn, lead to a corresponding reduction in the level of criminal offenses in this area. On the other hand, there was no statistically significant decrease in the number of criminal offenses in Ukraine. In addition, only in 2019 Ukraine reached the optimal scientifically proven average of 300: 1. The average ratio between the number of administrative offenses in the field of traffic and the number of accidents on average over four years (2017-2020) was 1540: 100. Statistics show that despite the increase in the ratio of administrative offenses and road accidents with each passing year, there has been no decrease in the number of road accidents. In addition, on average over four years (2017-2020) there were 95 administrative offenses per one accident with victims, 716 administrative offenses per one person killed in such accidents, and 76 administrative offenses per one injured person. The average ratio for four years (2017-2020) between road accidents and road accidents with victims is 6.19: 1. In other words, every 6-7 accidents were with victims. A positive trend is the increase in this ratio in recent years

The object of this research is the design of an affordable desiccant dryer for local farmers for seed and vegetable drying. The subsequent increase in food production has led to an accompanying need for easy, safe, and affordable preservation methods. This has led to a substantial increase in the number of driers, which are expensive for local farmers to acquire. Seeds and certain vegetables do not do well, under the high heat used in most dryers for drying as the drying process is often used as a final production step before packaging and selling agricultural products. Desiccant drying is hygienic, low energy, low cost, and safe method of drying agricultural products without degrading them or reducing their nutritional quality. A desiccant air dryer for seeds and vegetables was designed and constructed, and its performance was tested using bitter leaves (Vernonia amygdalina). Desiccant dryer materials were carefully sourced and selected based on the cost of the materials, availability, strength, lightness (weight), and resistance to rust. The desiccant dryer chamber has external dimensions of 43 cm by 30 cm and internal dimensions of 28 cm by 25 cm. The drying chamber is divided into five layers; each layer is 48 cm by 44 cm with a total surface area of 0.2112 m2.
Results showed significant moisture loss in the dried sample in 26 hours from 167 g to 54.1 g when compared with ambient air drying values. Proximate analysis of the desiccant dried bitter leaf higher values across all parameters when compared with the sample dried using ambient air. From the results obtained, it was therefore concluded that the desiccant dryer dried the samples faster than the common air-drying method. It was recommended that seed and vegetables should be dried in a desiccant dryer in other to increase shelf life and reduce perishability.

Published: April 2022

The object of this research is the cracking of the nuts of oil palm (Elaesis guineensis). The oil palm tree is one of the greatest economic assets a nation can have, provided its importance is realized and fully harnessed. After the oil extraction of palm oil from the palm fruits, virtually all methods involved in palm kernel nut cracking both in traditional and small-scale exist in scattered or separate units of operations. Hence, this research focused on designing a palm nut kernel cracking unit incorporating a separator in form of a screen to separate cracked palm kernel nut shell from kernel. The result shows that there were significant difference (p≤0.05) among the moisture content of the palm nuts, shaft speed of the machine and weight (feed rate), having a significant difference between:
– moisture content of the palm nut and the shaft speed of the cracker;
– moisture content and feed rate;
– shaft speed and feed rate.
There exist interaction between cracked, uncracked shell, damaged, undamaged kernel, and palm kernel nut breakage ratio. While, there was no significant difference among interaction between moisture content, shaft speed and feed weight. The result also indicated that for the highest speed of 1,800 rpm at a feed rate of 700 kg/h for all moisture contents, the cracking efficiency was between10 to 90 %, which implies that the kernel cracking efficiency increases with an increase in machine speed. However, it was observed that higher cracking efficiency was at the cost of higher kernel damage for all cracking speeds and feed rates, which is a problem. The kernel breakage ratio ranged from 1.040–7.85 for all feed rates and moisture contents. The kernel breakage ratio increased with moisture content and cracking speed but decreases with feed rate weight.
