The number of passenger automobiles, buses, cargo cars, and motorcyclists on the road in Indonesia continues to rise year after year. According to the Central Statistics Agency, the number of transportation equipment in 2015 was 105,303,318 million, up 6.5 percent from the previous year. In 2016, it was 112,205.711 million, up 6.5 percent. As can be seen from the above, Indonesia's transportation options are expanding throughout time. As a result, the demand for lubricants rises as well. As the need for lubricants grows, so does the amount of spent lubricants that is thrown away. Water absorption is inhibited by used lubricant waste that is disposed of in the soil. Given the aforementioned issues, a solution for converting spent lubricant waste into something more useful, such as liquid fuel, is required. Making a prototype for turning spent SAE 5W-30 lubricant waste into liquid fuel using the hydrocracking method with the help of a Ni/ZAA catalyst is one approach to go about it. The effect of temperature fluctuations of 300 °C, 350 °C, 400 °C, 450 °C, and 500 °C was employed as the independent variable in this investigation. The amount of used lubricant feed used in this investigation is 641.10 ml, which is a fixed variable. The best yield values were obtained at a temperature of 400 °C with a cetane number of 76.2, which met the diesel requirement.

Criminal Cases as a Source of Everyday History of the Parish Clergy in Volyn at the Early 17th Century
Authors: Dovbyshchenko Mykhailo
Published: January 2023

The article deals with the problems of everyday life of the parish clergy of Volyn during the Lithuanian-Polish era. It is noted that such a topic is important in the context of the study of the cultural and national movement on the Ukrainian lands at the border of the 16th and 17th centuries. The importance of criminal cases of district courts of the Volyn Voivodeship for the study of everyday problems of all strata of the Ukrainian population of this era, in particular the parish clergy, is emphasized. The author expressed the opinion that criminal cases reflected evidence about everyday life that could not be recorded in other sources available to modern scientists.The purpose of the article is to reveal a number of aspects of the daily life of the Volyn parish clergy using the example of the protest of a priest from the village of Biskupychi, Fr. Hryhoriy Zhukovych, as well as the testimony of the ministerial in this case. The analysis of Kostyantyn Gulevich’s crime – beating the victim, as well as rape and robbery of his wife (in the victim’s interpretation) made it possible to draw the following conclusions: first, the crime had not only a sexual motive and the desire to rob. The criminal also sought to humiliate the social dignity of the victim. This was manifested in her dressing in peasant clothes and a violent peasant-style haircut. Secondly, based on the protest and the ministerial’s testimony, it was possible to discover additional information about the history of Ukrainian clothing. According to the list of selected items, it was concluded that the bishop’s wife had quite expensive clothes and could afford to wear silver and gold jewellery. The forced dressing of the victim in peasant clothes gave additional insights into what the peasants wore at that time. Thirdly, the text of the protest made it possible to reveal the figure of the vernacular using the example of both individual words and idioms. In addition, an archaic term related to the metrology of those times and dating back to the princely era was discovered. Finally, a conclusion was made about the perspective of further research of the materials of criminal cases for the study of a wide range of problems related to Ukrainian everyday life during the Lithuanian-Polish era.

Published: January 2023

The article analyzes the impact of the full-scale aggression of the Russian Federation against Ukraine on the modern ethno-cultural and national-patriotic development of Ukrainian students based on the materials of a sociological survey. It is proved that the results of the sociological research make it possible to characterize professionally the influence of the policy of Russian neo-imperial revanchism on ethno-cultural characteristics and others related to them among student youth. It is shown that studentship as a socio-cultural community is characterized by a certain commonality of views, social norms, value systems, guidelines and interests. It is noted that since February 24, 2022, as a result of Russia's aggression there has been a sharp change in the ideological views of Ukrainian students regarding any markers associated with the aggressor country. "Decommunization" and "derussification" of student opinion took place, everything "Soviet" is now perceived by them as Russian and hostile. It was revealed that the level of linguistic self-identification of student youth, according to the results of a sociological survey, is steadily increasing, and the war, as a challenge for the entire society, only accelerates this process, therefore, the Ukrainian language, as one of the cornerstones of statehood, is only getting stronger today, and the lines of opposition in this matter are disappearing. It was revealed that, according to the majority of surveyed students, the full-scale military aggression of the Russian Federation against Ukraine led to the consolidation of Ukrainian society and increased patriotic feelings of citizens, therefore the vast majority of respondents joined the resistance to Russian aggression in Ukraine. It was found that the students are very interested in the events that have been taking place in Ukraine during the Russian military aggression that began in 2014, the vast majority of the respondents feel responsible for the fate of Ukraine and are convinced that it can affect its future. It was found that more than half of the respondents support receiving the Tomos on the Autocephaly of the Orthodox Church of Ukraine.

«Convinced and Interested in Gifts»: The Trial of the Nobleman's Servant Jan Pelygrymovskyi in 1623
Authors: Huliuk Ihor
Published: January 2023

The article raises the problem of enmity among the Volyn nobility in the second half of the 16th – the first half of the 17th century. The place of a nobleman in society, according to the early modern law is analyzed. It is indicated that on the territory of Europe at that time, and therefore also in Volyn, legislative bodies secured a privileged place for the nobility, protecting their personal freedoms and rights, which had a direct impact on the formation of the values of the noble community. It was emphasized that belonging to the society elite did not guarantee a safe and conflict-free life, which was closely related to noble needs that required constant contact with other members of society. The interpretations of the szlachta conflict in historiography are analyzed. It is stated that the majority of historians see the connection of this phenomenon with the nature of the early modern state, and with the features of the social order. The point of view according to which excessive conflict was a consequence of improper functioning of the executive branch of power, which created a field for social confrontations was highlighted. It has been established that in historical research this aspect is interpreted as characteristic of the culture of that time and such that in the perception of the nobility itself, it looked like regularity in which it knew how to navigate, reacting to each subsequent gesture and new stage of the conflict. The caveats regarding acted materials pointed out by Maria Bogucka and the approaches to work with the historical source, Jerzy Topolski drew attention to, were analyzed. All of the above aspects are considered from the local history angle – the case of the murder of the Volyn nobleman Hryhorii Bylynskyi and the trial of the accused. The behavior and statements of the szlachta during the trial, which took place in September–October 1623 in the Lutsk court, were analyzed. Jan Pelygrymovskyi`s motives in committing the crime are highlighted and analyzed. The involvement and interest in its implementation of a possible customer of a murder – Martyn Bohush, was traced. Possible versions of the murder are highlighted and the course of the trial is shown. Attention is drawn to the facts that despite the presence of two versions of the murder in the sources, this does not simplify the task of interpreting the event itself, and even complicates it, since we often do not have necessary evidence at our disposal. In order to cover all possible aspects of the murder, the importance of patron-client and family relationships was considered. Attention is drawn to specific manifestations of the everyday culture of this time, which shed light on szlachta customs in Volyn in the second half of the 16th – the first half of the 17th centuries.

Wireless Fidelity (Wi-Fi) fingerprinting is a remarkable approach developed by modern science to detect the user’s location efficiently. Today, the Global Positioning System (GPS) is used to keep track of our current location for outdoor positioning. In GPS technology, satellite signals cannot reach indoor environments as they are shielded from obstructions so that indoor environments with a lack of Line of Sight (LoS) do not provide enough satellite signal accuracy. Since indoor environments are very difficult to track, thus, a wide variety of techniques for dealing with them have been suggested. The best way to offer an indoor positioning service with the current technology is Wi-Fi since most commercial infrastructure is well equipped with Wi-Fi routers. The use of Wi-Fi fingerprinting techniques is becoming more common in the field of indoor positioning systems (IPS). For the purpose of indoor location localization, each method for obtaining a Wi-Fi fingerprint has been analyzed and discussed in this work. In this study, the majority of the algorithms that are associated with Wi-Fi fingerprinting have been interpreted, and the earlier works of other researchershave been critically evaluated, in order to get a more in-depth understanding of how the Wi-Fi fingerprinting process works.

In recent times, damage identification based on vibration methods are emerging as common approaches, in which the techniques apply the vibration response of a monitored structure, such as modal frequencies and damping ratios, to evaluate its condition and detect structural damage. The basis of the vibration-based health monitoring method is that when there are alterations in the physical characteristics of a structure, there will also be changes in its vibration properties. This paper proposed a neuro-fuzzy artificial intelligence method, called adaptive neuro-fuzzy inference system (ANFIS), to detect damage using modal properties. To generate the modal characteristics of the structures, experimental study and finite element analysis of I-beams with single damage cases were performed. The results showed that the ANFIS approach was able to detect the magnitude and location of the damage with a significant degree of precision, and notably reduced computational time.

This paper describes the fabrication of aluminum-zinc (Al-Zn) alloy (AZ91E) metal matrix composites augmented with Fly Ash (FA) and zirconium dioxide (ZrO2) particulate utilizing the vortex method and a stir casting process. The researchers introduced composites with ZrO2and fly ash at varied weight % ranging from 0 to 10 with 53 μm particle sizes. The inclusion of ZrO2 particle reinforcement increased the hardness significantly, whereas the ultimate yield and tensile strengths increased somewhat. As the weight % of ZrO2 particles was increased, the permeability and density of Al-Zn alloy based composites increasing. When compared to the comparable alloy, composite densities were lower, which might be attributed to the low density of the FA. Additionally, the compressive and tensile crack properties of the composites produced were investigated. Microstructural analyses confirmed the presence of evenly dispersed FA and ZrO2 particles throughout the matrix, but an EBSD study revealed that this led to the diminished reduction. The inclusion of FA particles enhanced the material’s tensile properties and hardness including ultimate yield and tensile strengths. The strengthening mechanisms underlying the enhanced properties were discussed. At the point when ZrO2 and FA fortifications were applied, a definite tensile and yield strengths raised in contrasted with the basic compound. As revealed by the aftereffects of the examination, the grain size of the Al-Zn composite built up with FA and ZrO2 particulates is a lot of lower than the grain size of the lattice compound.

Several methods are available for use, to deliver the gene of interest into plants. Among these, Agrobacterium-mediated transformation utilizes binary vector systems to achieve the stable transformation of plants. Alas, this process is labor-intensive and time-consuming as several months are needed to obtain a true transgenic plant. Transient gene expression (e.g., vacuum-infiltration) systems were offered as an alternative over stable transformation, specifically to overcome time-related drawbacks. However, this method requires expensive equipment such as vacuum chambers. In this study, we report a vacuum-infiltration protocol for the transient expression of a reporter gene, modified green fluorescent protein (mGFP), in tomato seedling. With a basic experimental setup (including a custom-built growth chamber) with affordable equipment, we showed that the entire leaf can be infiltrated by applying a mere 200 millibar vacuum for 6 minutes, and thus the transient expression can be achieved in tomato plant, evidenced by PCR-based detection of the T-DNA, detection of mGFP both analytically with SDS-page analysis, and visually by the images acquired by fluorescence microscopy. Furthermore, different Agrobacterium tumefaciens strains were tested for their transformation efficiency, and we showed that LBA4404 was the most effective strain to use in the vacuum-assisted transient expression.

Türkiye’de yetiştiriciliği en çok yapılan yumuşak çekirdekli meyve türlerinden birisi olan armut (Pyrus communis L.) önemli bir ihracat ürünüdür. Marmara Bölgesi’nde armut üretimi en fazla Bursa İlinde yapılmaktadır. Armut yetiştiriciliğinde verimi etkileyen en önemli bitki koruma sorunlarının başında Armut yaprak pireleri olarak bilinen zararlı, Armut psillidi, Cacopsylla pyri (L.) (Hemiptera: Psillidae) gelmektedir. Zararlının nimf ve erginleri armut ağaçlarında doğrudan ve dolaylı zarar yapar. Esas zararı yapan nimfler çiçek, yaprak, tomurcuk ve sürgünlerde emgi yaparak beslenir ve balımsı madde salgılarlar. Salgıladıkları tatlımsı maddeler ile solunum ve fotosentezi engeller ve meyvelerin pazar değerini düşüren bir isli yapı (fumajin) oluşturur. Yoğun bulaşmalarda ağaçların gelişmesi durur; yaprak, çiçek ve meyve dökülmeleri, meyve şekil bozuklukları meydana gelir. Birkaç yıl tekrarlayan yoğun bulaşmalarda ağaçların dallarında ve tümünde ölüm meydana gelir. Ayrıca bazı hastalık etmenlerinin (özellikle ateş yanıklığı hastalığı) vektörlüğünü yaptıkları da bilinmektedir. Bu sebeple zararlının kontrolünde gerekli önlemlerin alınması önemlidir. Bu amaca yönelik ele alınan çalışmada zararlının yayılış alanının belirlenmesi hedeflenmiş olup, çalışma Bursa ilinin en çok armut yetiştirilen 9 ilçesinde (Osmangazi, Kestel, Gürsu, Yıldırım, Kemalpaşa, Karacabey, İznik, Nilüfer ve Orhangazi) 2020-2021 yıllarında yürütülmüştür. Zararlının varlığı sarı yapışkan tuzak, japon şemsiyesi ve gözle kontrol yöntemi ile belirlenmiştir. Çalışmada Bursa ilinin armut yetiştiriciliği yapılan tüm ilçelerinde bahçelerin zararlı ile bulaşık olduğu (%100) ve zararlının yayılış gösterdiği tespit edilmiştir. Özellikle mayıs ve temmuz aylarında zararlının yoğun olarak bulunduğu gözlemlenmiştir. En fazla bulaşma Kestel ve Gürsü ilçelerinde tespit edilmiştir. Osmangazi ve Yıldırım ilçelerinde bulaşmanın orta seviyede; Nilüfer, Karacabey, Kemalpaşa, Orhangazi ve İznik ilçelerinde ise bulaşmanın az olduğu belirlenmiştir.
