The search for new possibilities for graphical user interfaces has turned out to be a very important part of the software, not only for functional reasons or for using the application to fulfill the slogan of an intuitive task, but also because it has been demonstrated at times. Dijkstra's algorithm uses a data structure to store and query partial solutions ordered by distance from the beginning. Development giants spend a lot of resources creating more elegant and intuitive user interfaces for their products, because they have experienced firsthand how useful, well-designed software can sometimes fail when its GUI fails. Dijkstra's algorithm is an algorithm used to determine the shortest trajectory from a certain point to any other point on a graph. In the course of the work, it was possible to generate an application that graphically solves Dijkstra's algorithm. Compatible with Windows, Ubuntu, macOS operating systems using Java programming language. This application serves as a guide to understand concepts related to graph theory and understand how Dijkstra's algorithm works, as well as topics related to object-oriented programming.

Published: October 2023

Business intelligence (BI) integrates and analyzes the behavior of historical data streams, obtaining predictions. The project allows companies in the agricultural sector dedicated to the cultivation and export of avocados to make decisions based on artificial intelligence, promoting growth and competitiveness in the market. Models that apply data analytics are implemented through simple linear regression and recurrent neural networks (RNN). To carry out the project, data extraction, transformation, and loading (ETL) processes were used. The coding was developed in Python with the Django framework, using the sklearn, linear_model, LinearRegression, seaborn, stastsmodels and tensorflow libraries, among others. In the predictions for the years 2016 to 2021, greater precision was verified in the linear regression model. When making the export projection for the next six years, the results coincide with a minimal difference between the two models.

Adverbielle Präfigierung im Sprachkontakt: Partikelverben und ihre aktionale Rolle im Burgenlandkroatischen
Authors: Berghaus Jasmin
Published: October 2023

This article shows that particle verbs in Burgenland Croatian – a notable morphosyntactic phenomenon of language contact – may form aspectual pairs in a typically Slavic manner. Particle-based pairs with an indigenous base verb are formed by means of suffixation, suffix opposition, suppletion or prefixation. In the case of spatial relations, by contrast, preverbs predominate over prefixes, leading to a reduction of the old inventory of verbal compounds. Nevertheless, preverbs are only rarely obligatory in the formation of aspectual pairs. In the case of borrowings, only prefixation is productive, which might be attributed to German (and Hungarian) influence. On a par with other aspectual pairs, particle-based formations may express taxis relations (sequence, simultaneity, incidence). Language contact possibly contributed to the preservation of the Contextually Conditioned Imperfective Past also in imperfective particle verbs.
Глагольный вид в македонском диалекте Бобоштицы-Дреновы и албанско-славянские контакты
Authors: Makartsev Maxim
Published: October 2023

Verbal aspect in the Macedonian dialect of Boboshtica-Drenova and Albanian-Slavic language contact - Long-term subdominant bilingualism with Albanian has had a significant impact on verbal aspect marking in the Macedonian dialect of Boboshtica-Drenova (South-East Albania). The Slavic formal opposition of perfective and imperfective aspect marked through a variety of derivational methods has been preserved. However, under Albanian influence two continuous aspect con­structions have been grammaticalised in the dialect, one of them based on the locative ǵe, and the other on the adversative conjunction toko. The paths of grammaticalization of these markers are investigated, which include structural transfer (ǵe < locative and temporal tek, toko < adversative and continuous po), which is partially supported by the phonetic similarity between the respective Albanian and Macedonian dialectal markers (toko || duke, tek).
L’interazione tra la diatesi Non-attiva e le categorie di tempo e aspetto. Microvariazione nei dialetti italo-albanesi
Authors: Turano Giuseppina
Published: October 2023

This article deals with morphological non-active verbal voice, which characterises reflexive, middle and passive structures in Standard Albanian and Arbëresh dialects. The data, compared to those of Italian, show that the three different strategies for the realisation of Standard Albanian and Arbëresh non-active morphology interact with the categories of mood, tense and aspect. In particular, these morphological strategies determine a perfective/ imperfective split as well as a series of restrictions which convey different interpretations associated with a stative or eventive interpretation. Particular attention is paid to the possible influence of Italian structures on the Italo-Albanian varieties in the domain of non-active voice.
Sprachkontaktdynamiken im aspektuellen System. Neue Evidenz zur Progressivperiphrase aus dem Zimbrischen von Lusérn
Authors: Bidese Ermenegildo
Published: October 2023

This article sets out to present a recent study of progressive and prospective periphrases in Cimbrian, a German-based variety spoken in Northern Italy. Our research complements a renewed interest in the grammaticalization processes of progressive periphrases in inland-German dialects and standard German, focusing on German-based dialects that are spoken in isolation, namely not under the roof of Standard German. In such varieties similar processes take place; they show, however, accelerated dynamics due to the contact situation and can, thus, shed light on the diachrony of German and its dialects. In relation to the aspectual constructions in Cimbrian, we discovered a previously undocumented perspective periphrasis, viz. soin drumauz + zu-INF, which, however, is destined to be discarded from the aspectual system of Cimbrian on account of the expansion of the more general periphrasis soin nå + zu-INF. In terms of the dynamics of contact-induced grammar change, our research confirms that new constructions in a contact language are not simply the replication of those in the donor language but, rather, represent the internal recombination of abstract features in the aspectual system of Cimbrian.
Il ruolo del contatto nell’aspetto perfettivo in griko: forme sintetiche ed analitiche in competizione
Authors: Ledgeway Adam , Schifano Norma , Silvestri Giuseppina
Published: October 2023

The aim of this article is to discuss a change in the expression of perfective aspect in Griko. According to Rohlfs (1977), this variety of Italo-Greek only possesses a synthetic past perfective form, thus failing to mark a distinction between the past punctual and present perfect values of the perfective. And yet, some changes in the expression of this macrocategory were already taking place at the time of Rohlfs when an originally resultative periphrastic form was beginning to be used beyond its original limits. By taking into account a wider array of sources, including both early and contemporary written attestations, as well as data collected with native speakers, we show how the regrammaticalization of this analytic construction, from resultative to present perfect marker, was already under way in the late nineteenth century and is now completed for some speakers. The article concludes with a number of reflections about the role played by contact in these developments.

Determinants of the imports of essential medical products by European Union
Authors: Marti Luisa , Puertas Rosa
Published: October 2023

The rapid spread of the COVID-19 pandemic has triggered a marked distortion in the trade of medical products needed to combat its severe effects on the health of infected individuals. This study sought to examine the determinants of imports by the 27 countries of the European Union (EU-27), through a panel data analysis for the period 2015 – 2020. The aim is to shed light on the distinct behavior of imports of each of the seven products classified as essential by the World Customs Organization and the World Health Organization. To that end, economic and social characteristics of the buyer country were treated as explanatory variables, along with the origin of the goods and the effect of the virus in 2020. The results showed that several determinants of imports of medical goods have a homogeneous influence on all of these products. This is also in line with gross domestic product per capita and population, which showed positive and significant coefficients for all products. The level of wealth of a country reflects its purchasing power, and thus capacity to purchase essential goods. Furthermore, an aged population in a territory is indicative of the greater need for essential medical products, which was amplified in 2020 due to the high vulnerability of this group to the symptoms of the virus. The present study confirmed that EU-27 trade agreements curbed the mass entry of non-EU products and that COVID-19 pandemic increased imports of certain products.

Published: October 2023

The article considers the results of studying the thermodynamic computer modeling of the interaction of phosphorite (Karatau basin, Kazakhstan) with carbon and coke performed using the HSC-10 software package and electric smelting of the phosphorite with coke and steel shavings in an arc furnace. The modeling allowed us to determine the equilibrium extraction degrees of phosphorus into gas (Р2, Р4), silicon into ferroalloy in the form of iron silicides (FeSi2, FeSi, Fe3Si, Fe5Si3, Si) and calcium into CaС2. At temperatures above 1500 °C, regardless of the amount of iron, the extraction degree of phosphorus into gas is more 99%. The resulting ferroalloy contains 21.2-23.8% of Si, 1.6-2.8% of Al; the calcium carbide has a capacity of 288-325 dm3/kg. The extraction degree of silicon into the alloy was 89.8%, calcium in CaC2 – 72.5%, phosphorus into gas – 99.4%. The ferroalloy, formed at the electric smelting of the Chulaktau phosphorite together with coke and steel shavings and containing 24.9-29.8% of Si, is FS25 grade ferrosilicon, and the formed calcium carbide has a capacity of 278-290 dm3/kg and belongs to the third and second grades. The developed technology makes it possible to increase the degree of phosphorites’ comprehensive use two times (up to 87.5%).

Authors: Akbar Hersusiad , Novadian  , Mgs Irsan Saleh
Published: October 2023

Background: Acute kidney injury (AKI) is a clinical condition characterized by a rapid decline in kidney function that includes structural damage (injury) or malfunction (impairment). AKI is a common complication that occurs in 5-10% of patients due to various underlying etiologies. One of the underlying pathophysiology of AKI is the role of discharge reactive oxygen species (ROS), which causes injury to kidney cells. From various studies, it has been reported that N-acetylcysteine (NAC) has anti-inflammatory and antioxidant effects and has an effect on reducing serum creatinine values.

Methods: This research is an open randomized clinical trial without control involving 30 patients at Dr. Mohammad Hoesin General Hospital, Palembang, who were all given intervention in the form of NAC 1200 mg/day, starting in September – October 2023. This study aimed to determine the role of NAC in reducing serum creatinine values in patients with acute kidney injury at Dr. Mohammad Hoesin General Hospital, Palembang, Indonesia. Data analysis was carried out using SPSS 21 univariate and bivariate.

Results: From the research results, it was found that the average age of patients was 53.9 years, involving 21 males (70%, N=30) and 9 females (30%, N=30). The most common causes were prerenal and then renal (53.3% and 46.7%). The initial serum creatinine level was found to be 2.12± 0.79 mg/dL (n = 30 samples), and after administration of the intervention, the mean serum creatinine level was 1.28± 0.63 mg/dL (n = 30 samples). By using a paired t-test, there was a decrease in serum creatinine levels significant (p=0,012).

Conclusion: NAC administration to patients with acute kidney injury of pre-renal or post-renal causes has a statistical effect on reducing serum creatinine values in patients with acute kidney injury at Dr. Mohammad Hoesin General Hospital, Palembang, Indonesia.

No one presently makes fully automatic rotogravure machines in Indonesia. Tension control is one of the automation systems of a rotogravure machine.  In this research, tension control, kinds of tension control, and the building of a rotogravure machine tension control system are all topics that will be covered. It uses a descriptive qualitative approach. employing a literature review to gather data and descriptive statistics to analyze it. The study's findings demonstrate that the rotogravure machine is a fast printing device that uses substrates like paper, aluminum, and plastic. The printing procedure begins with the unwinding roll, moves to the infeed, and then continues with the first and second color printing processes, moving as necessary to the outfeed and rewinding roll using a tension control mechanism. The roller-to-roll mechanism used by the machine allows for the tension management because the printed material is subjected to varying strains that must be managed. A rotogravure machine can use four different forms of tension management, specifically speed control for unwinding and rewinding, speed control for unwinding and torque control for rewinding, and speed control for unwinding and rewinding. the creation of a tension control system for a rotogravure machine using the machine's main controller, a PLC and an HMI.

Motorized vehicles are the primary mode of transportation in the neighborhood. An automobile is one of the motorized vehicles. Because of the mixing of air and gasoline, cars may move. The spark plug plays a crucial function in combustion because it ignites the mixture of fuel and air to generate combustion. Incomplete combustion will consequently result in misfiring. Damage to the spark plug, injector, and ignition coil are just a few of the things that might lead to misfiring.  Therefore, due to misfiring, research on preventive maintenance for cars is required. Utilizing the vibration approach is one option. The combustion process in this study is stimulated by changing the 1000cc engine's speed. The engine speed ranges from 900 to 3500 revolutions per minute. The accelerometer sensor is then positioned vertically and horizontally on the machine's surface. According to this study, the first form mode's frequency at 900 rpm has an amplitude of 3,433 mm/s2 and occurs at a frequency of 69 Hz. In contrast, the first mode form occurs under typical circumstances at a frequency of 99 Hz and an amplitude of 1,254 mm/s2. Furthermore, at a rotational speed of 2500 rpm, the frequency in the first shape mode is abnormal at 69 Hz with an amplitude of . In contrast, under typical circumstances, the first form mode has a frequency of 249 Hz and an amplitude of 6,721 mm/s2. A frequency of 4x rpm was discovered for the rotational speed parameters of 900 rpm and 2500 rpm. This demonstrates that a misfiring-related bearing issue exists in the piston motor system.

The vehicle's power comes from the engine, which uses combustion to transform the chemical energy of the fuel into mechanical energy. The combustion temperature will have an impact on the engine's operating temperature if this situation is not adequately cooled. According to some literature, the PH adjuster additive is a combination of chemicals that works to raise the PH and alkalinity of water to improve the state of the water atoms for the cooling process. However, the process of cooling a vehicle radiator with water from the engine is very hot, so further study is required. Additionally, this PH adjuster may condition the water to your specifications. The purpose of this study is to ascertain the outcome of adding the PH adjuster additive composition to the radiator water of the 160 cc Vario motorcycle. The approach is a descriptive methodology based on the outcomes of experiments. According to research based on the experiments carried out in this study, adding 3% PH Adjuster additives at 1000 rpm will produce the best engine performance. The amount of additives added also had an impact on the radiator performance of the 160 cc Vario motorcycle

Semantic attraction and production of occasional meaning

Published: October 2023

В статье рассматриваются механизмы создания новых смыслов. Предполагается, что связь между означаемым и означающим есть динамический процесс, который может привести к одновременной актуализации нескольких означаемых. Данное явление предлагается рассматривать как развитие принципа асимметричного дуализма языкового знака С. И. Карцевского, для него предлагается термин «семантическая аттракция». На примере окказионализма змеи в значении «таксисты фирмы “Кобра”» описаны операции и условия, приводящие к появлению новых значений.

We address some mechanisms of meaning production. The relationship between a signified and its signifier is a dynamic process that can lead to the simultaneous actualization of multiple “signifieds” (meanings). We suggest considering this phenomenon as a development of the principle of asymmetric dualism of the linguistic sign (Karcevski); the term “semantic attraction” is introduced for it. Drawing on the example of the occasionalism snakes (in the meaning: the taxi drivers of the Cobra company), we describe the operations and conditions leading to the emergence of new meanings.
