For this reason, the need for xeriscape design in landscape areas has increased in recent years. The aim of this study is to examine and evaluate the xeriscape landscaping in Selcuk University Alaeddin Keykubat Campus in line with the xeriscape principles. As a result of the examinations, it was determined that the xeriscape design areas in the campus were generally created in accordance with xeriscape principles.
Educational Venue from Design to Implementation Process; A Project by Faculty of Fine Arts, Selçuk University
Authors: Sungur Mine , Bakır İbrahim
Published: December 2023

Throughout history, there has been a reciprocal relationship between humans and space. Even though there are numerous spaces covered by this ongoing relationship process, it has integrated and gained value with educational venues. Mainly because they closely monitor social, cultural, technological, and economic developments and pass on knowledge to future generations, educational spaces play a crucial role in the development of individuals as well as society. It is feasible to conclude from research on educational spaces that the physical environment has a major positive or negative impact on education. To solve the issue that the current Faculty of Fine Arts at Selçuk University could not sufficiently respond to user needs physically, it was decided to construct a new Faculty of Fine Arts building. The primary goal of the study is to design the building using user-oriented techniques that promote social interaction and showcase artistic identity throughout the design phase. A qualitative research approach, based on inspection and observations, was used in the study to gather data, documents, and reports on the topic and to ensure that the architectural programming stages advanced correctly and received ongoing feedback. Studies have confirmed the results, which show that artistic education in structures that provide users with distinct experiences is different from that provided in faculty buildings with a type plan scheme. The process, which involves collaboration between stakeholders from various disciplines and necessitates coordination, is also maintained in a coordinated fashion as a consequence of the study. Because of this, it is believed that buildings with comparable features can offer direction by offering a set of data that may also be reliable for design procedures that are prearranged.

Silver Nanoparticles (AgNP) are silver particles of no more than 100 nm in size. Silver nanoparticles have antimicrobial characteristics and have been applied to various fields as antibacterial agents. This study aims to formulate and examine the antibacterial activity in preparing silver nanoparticle mouthwash on Staphylococcus aureus. The silver nanoparticles are synthesized using a chemical reduction method, of which the wavelength is then characterized using UV-Vis spectrophotometry, and the PSA instrument is used for particle size. Silver nanoparticles are formulated for a mouthwash with various concentrations such as 0%, 60%, 70%, and 80% consecutively as formula 1, 2, 3, and 4. The observation is then performed on the organoleptic, pH, stability, and bacterial activity of the Staphylococcus aureus using the disk diffusion method. The study results indicate that the preparation of silver nanoparticle mouthwash has a good organoleptic; the average pH of formula 1, 2, 3, and 4 consecutively is 3.40, 3.40, 3.46, and 3.54; however, it is not stable during the storage stage. The result of the antibacterial activity test on Staphylococcus aureus bacteria shows that formula 2 has the most oversized average inhibition zone diameter that is 13.14±0.31 mm compared to formulas 1, 3, and 4, namely 5.20±0.44; 12.40±0.74; and 8.40±0.89 mm. The active formula of mouthwash preparation to inhibit the growth of Staphylococcus aureus bacteria is formula 2.

Published: December 2023

Coronavirus Diseases 2019, caused by SARS-CoV-2, has been a significant threat to global public health. Unfortunately, effective COVID-19 vaccines and clinically-proven anti-SARS-CoV-2 drugs remain unavailable. This study was carried out aiming to predict the potential effect of mitragynine derivates from the Genus Mitragyna Korth as an inhibitor of Mpro, the main protease of the SARS-CoV-2, by in silico molecular docking study. The crystal structure of the main protease of SARS-CoV-2 as an active site target was obtained from the PDB database (rcsb.org) with PDB ID: 5R84 and 6LU7 with the native ligand of Z31792168 and N3, respectively. The analysis of in silico molecular docking was conducted using Autodock 4.2.6 (100 docking runs). The central grid was placed on HIS41 and CYS145 with a grid box comprised of 40x30x34 (for protein 5R84) and 36x62x40 (for protein 6LU7) points spaced by 0.375 Å was centered on the active site of X=9,812; Y=-0,257; Z=20,849 and X=-9.732; Y=11.403; X=68,483 (XYZ-coordinates), respectively. Our research indicated that mitrjavine and ajmalicine exhibit greater potential inhibition of the active site on the Mpro of SARS-CoV-2, even stronger than native ligands. We believed that these compounds are promising candidates to be examined in further COVID-19 drug discovery studies.

Published: December 2023

Papaya plants (Carica papaya L.) can be used as traditional medicine. The parts of the plant commonly used as medicine are the seeds and leaves. Assurance of the quality of the extract obtained needs to be carried out by testing specific and non-specific parameters. The aim of the study was to determine the effect of the percentage of ethanol solvent concentration on specific parameters (organoleptic, phytochemical screening, and total phenolic content) and non-specific parameters (moisture content, ash content, and specific gravity) of papaya seed extract (Carica papaya L.). This type of laboratory experimental qualitative research was done to determine the effect of the percentage of ethanol solvent concentration (70% and 95%) on specific and non-specific parameters. Specific and non-specific parameter testing is based on work procedures listed in the Indonesian Herbal Pharmacopoeia. The results of testing the specific parameters on organoleptics showed no difference in the extract obtained, which was viscous and dark brown in color with a characteristic odor. Based on qualitative phytochemical screening, 70% ethanol extract contains alkaloids, flavonoids, tannins, and saponins. However, the 95% ethanol extract was only positive for alkaloids, flavonoids, and tannins. The phenolic content test of 70% ethanol and 95% ethanol extracts was 4.31 ± 0.65 mg GAE/g and 2.69 ± 0.41 mg GAE/g, respectively (Sig 0.022 < 0.05). Extract non-specific parameter test results. The ash content test for 70% and 95% ethanol extracts was 9.5% ± 0.21% w/w and 8.5% ± 0.06% w/w (Sig 0.043 < 0.05). The respective water contents were 8.7 ± 0.11% w/w and 9.7 ± 0.26% w/w (Sig 0.046 < 0.05). The specific gravity of each obtained was 0.88 ± 0.006 % g/ml and 0.75 ± 0.006% g/ml (Sig 0.043 < 0.05). The conclusion of this study is that the concentrations of 70% ethanol  and 95% ethanol in papaya seed ethanol extract have an effect on specific parameters, namely the measurement of total phenolic content. While the non-specific parameters affect the water content, total ash content, and specific gravity.

Teknik fotogrametri untuk mendapatkan model studi digital tiga dimensi dalam perawatan ortodonti
Authors: Gadih Pratomo Harris , Arief Budiman Johan
Published: December 2023

In the field of orthodontics, study models play an important role as diagnostic aids, photogrammetry techniques are used to obtain three-dimensional digital study models. This study model provides an accurate representation of the patient's teeth and occlusion, as well as assists in identifying dental and bone anomalies. In the creation of study models, traditional techniques using cement or gypsum are time-consuming and prone to inaccuracies. Three-dimensional scanning is the process of collecting and analyzing real-world objects or environments using digital data against their possible shapes and appearances. The collected digital data is then processed using three-dimensional scanning software so that it can be used to create three-dimensional digital models. Therefore, the use of photogrammetric techniques can improve efficiency and accuracy in orthodontic treatment. Photogrammetry requires several stages and the necessary equipment to produce good results. Photogrammetry itself has advantages and disadvantages. The three-dimensional digital study model is a better alternative to the traditional study model because it is not susceptible to physical damage, requires small digital storage space, can be transmitted instantly electronically, is a means of educating patients, and can be manipulated virtually.
Performance Analysis of Cooperative NOMA for Different Power Allocation Strategies
Authors: Saeed Shatha Hellan , Sileh Ibrahim Khalil
Published: December 2023

Cooperative None Orthogonal Multiple Access (C-NOMA) is a promising approach for 5G and beyond communication networks. Users will benefit from the full bandwidth of the channel without time constraints. NOMA’s features are incomplete without efficient power allocation that ensures power distribution among users fairly. Integrating power management (allocation) with Cooperative-NOMA (C-NOMA) may improve the system metrics. In addition, a physical layer security (PLS) is added to make the process of sending and receiving safe, and the system works in an integrated manner, preventing any interrupting or eavesdropping inside or outside the network. This paper demonstrates the user and channel performance of C-NOMA with Amplify-and-forward (AF) and Decode-and-forward (DF) approaches. The analysis is performed by varying the power allocation techniques to derive the best system configurations. The simulation results confirmed the analytic findings and showed that the proposed system outperforms orthogonal multiple access (OMA), conventional NOMA, and conventional cooperative NOMA, enhancing the performance metrics in terms of throughput, sum rate, and outage probability. The bit-error-rate (BER) of the far user can be identical to that of the near user if power allocation is properly set. All techniques excelled except for the fixed power allocation, which had the same BER. The Channel capacity and outage probability were also considered. A slight variation in the channel capacity in all the experiments for different numbers of users was found. The generalized power allocation for AF and DF models had the optimum channel capacity close to 14 bps/Hz. Moreover, far users always had a higher outage probability than near users and channels, and generalized power allocation was the highest outage probability technique when the transmit power was close to (4 dB).

Authors: Bersanova Zaira Yunusovna , Kulbuzheva Tamara Akhmetovna
Published: December 2023

The subject of the study is the history of the traditional churn and milling activity of the population of Ingushetia in the late nineteenth and early twentieth centuries. The authors consider it in detail on the basis of data from ethnographic expeditions and archaeological excavations. It should be noted that the churn – the equipment with which butter is produced and the hand mill – occupied an important place in the industrial life of society. Information about them is available not only in archaeological materials, but also in written sources. This approach allows the author to determine the cause-and-effect relationships of events, facts and the state of the traditional butter and flour industry of the population of modern Ingushetia. The research is based on historical, cartographic, statistical, sociological methods; historical materials about the butter industry in Ingushetia are used. The scientific novelty of the research lies in the analysis of ethnographic objects such as a churn and a hand mill; their properties and functions are determined; a holistic approach to the concepts of "churn" and "hand mill" as a multifunctional phenomenon is formed; A comprehensive historical and cultural analysis of traditional household items among the Ingush has been carried out. The main contribution of the authors is that for the first time in ethnographic science, an attempt was made to study objects intended for the production of food products of the Ingush population, both in general and ethnologically. The voluminous presentation is given on the basis of a new scientific approach to a well-known topic, i.e. Based on ethnographic, historical and folklore material, an attempt has been made to classify and analyze the factors of formation and development of the nutrition system in Ingushetia, a systematic presentation and scientific analysis of issues related to the functions of food preparation.

Blended Labs in den Ingenieurwissenschaften – die Entwicklung einer Alternative zu Laborpraktika nach dem Design-Based-Research-Ansatz
Authors: Wermann Caroline , Odenbach Stefan
Published: December 2023

Die Nachfrage nach Bildungsformaten, die ortsunabhängig durchführbar sind, ist groß, und die Inklusion in der Lehre gewinnt an Bedeutung. Lehrmethoden sollten sowohl verschiedene Lerntypen ansprechen als auch für Menschen aus unterschiedlichen Lebensumstände zugänglich sein. Während es zahlreiche Ansätze für Vorlesungen, Seminare und Übungen gibt, ist die Umsetzung von Laborpraktika in alternativen Formaten noch vergleichsweise neu und aufwendig.

Das Pflichtmodul "Mess- und Automationstechnik" der TU Dresden, besucht von ca. 300 Studierenden pro Semester, stand vor der Herausforderung, Praktika während der COVID-19-Pandemie in alternativen Formaten anzubieten. Aufgrund der Studierendenzahl und da die Handhabung von Geräten ein wesentliches Lernziel ist, fiel die Wahl auf das Blended-Learning-Format.

Das Forschungsziel ist die Entwicklung eines Blended-Learning-Praktikums zum Thema Dehnungsmessung. Die Studie ist entsprechend dem Design-Based-Research-Ansatz angelegt und verfolgt Forschungsfragen zur Betreuung der Studierenden und auftretenden Lernhindernissen. Die Evaluationsergebnisse zeigen, dass durch den Einsatz von Logbüchern eine Verbesserung der Betreuung erreicht wurde. Außerdem konnten erste Lernhindernisse bei der Bearbeitung des Praktikums identifiziert werden.

Der Alltag wissenschaftlicher Mitarbeiter: innen wird durch die Dualität zwischen Lehre und Projektarbeit geprägt. Module bestehen meist aus Vorlesung- und Praxisteilen. Diese werden oft über mehrere Semester wiederholt und sind für alle Studierenden gleich. Wissenschaftliche Mitarbeiter: innen oder Studierende höheren Semesters betreuen diese, ohne direkten Mehrwert in Projekten.

Im Rahmen des Masterstudiengangs Textil wird die Möglichkeit evaluiert vorgefertigte Praktika durch, im Vorfeld an aktuelle Forschungsprojekte angepasste, Aufgabenstellungen zu ersetzen. Diese werden in Form einer offenen Problemaufgabe am Anfang des Semesters präsentiert. Die Studierenden bearbeiten ihre persönliche Aufgabenstellung im Zuge der Lehrveranstaltung. Die Vorlesungsinhalte befähigen zur selbsständigen Nutzung industrierelevanter Softwarepakete. Die didaktische Analyse nach Klafki erfolgt nach Abschluss der Lehrveranstaltung [1, 2].

Alle teilnehmenden Studierenden konnten ihre Aufgabenstellung erfolgreich bearbeiten. Die wissenschaftlichen Mitarbeiter: innen erhielten qualitativ hochwertige Ergebnisse, die in laufenden Projekten verwendet werden konnten. Die praktische Klausuraufgabe wurde von allen Studierenden erfolgreich und mit individuellen Ansätzen bearbeitet.

Die Ergebnisse dieses Versuches zeigen, dass individuelle und projektbezogene Aufgabenstellungen zu gesteigerten Kompetenzgewinnen führen und gleichzeitig verwertbare Ergebnisse für die Dozenten liefern kann. Die Mitarbeit an Forschungsprojekten git den Studierenden Einblicke in aktuelle Forschung.

Кулачковые насосы (КН) применяются в пищевом производстве для перекачивания жидкостей с большой вязкостью. Для эффективной работы необходимо тщательно подходить к подбору насосов, опреде- лять зависимости производительности от различных факторов и оценивать энергетические показатели. Методика оценки энергетической эффективности КН, в отличие от других типов насосов для перекачки пищевых сред, от- сутствует. На основе собственных и полученных другими исследователями экспериментальных данных разра- ботан метод расчета показателей энергетической эффективности КН с учетом влияния вязкости перекачиваемых жидких пищевых продуктов – плавленого сыра, сливок с различной жирностью. Установлено, что при сниже- нии температуры вязкость плавленого сыра существенно увеличивается, что приводит к большому росту пока- зателя затраченной мощности. Выявлено, что увеличение перепада давления вызывает рост КПД и снижение удельных энергетических затрат. При поборе КН для системы непрерывной подачи пищевых масс по критерию энергетической эффективности рекомендуется ориентироваться на показатель удельных энергетических затрат.

Lobe pumps (LP) are used in the food industry for pumping liquids with high viscosity. For efficient operation, it is necessary to carefully approach the selection of pumps, determine the dependence of performance on various factors and evaluate energy performance. Unlike other types of food pumps, there is no methodology for assessing the energy efficiency of LP. Based on their own and experimental data obtained by other researchers, a method has been developed for calculating the LP energy efficiency indicators, taking into account the influence of the viscosity of pumped liquid food products – processed cheese, cream with different fat content. It has been established that with a decrease in temperature, the viscosity of processed cheese increases markedly, and this leads to a large increase in the power consumed. It was found that an increase in pressure drop causes an increase in efficiency and a decrease in specific energy costs. It is recommended that when selecting LP for a system of continuous supply of food masses, according to the criterion of energy efficiency, focus on the indicator of specific energy costs.

Для уменьшения потерь и увеличения сроков хранения плодоовощной продукции используют хими- ческие, биологические, физические методы обработки сырья перед закладкой на хранение. Нами разработана тех- нология хранения яблок, включающая перед закладкой обработку плодов биопрепаратом на основе листьев и око- лоплодников грецкого ореха и электромагнитным полем низкой частоты. В качестве объекта исследования были яблоки сорта Айдаред, заложенные на холодильное хранение без обработки (контроль), с обработкой только био- препаратом и по усовершенствованной комплексной технологии – биопрепарат + воздействие ЭМП НЧ. Установ- лено, что биопрепарат в комплексе с обработкой ЭМП НЧ способен оказывать существенное влияние не только на продолжительность хранения плодов, но и на их качество. Плоды, прошедшие комплексную обработку, сохранили привлекательный внешний вид, были плотными и сочными и имели более высокие органолептические показатели по сравнению с необработанными плодами контрольного образца. Выявлены кинетические зависимости изменения активности ферментов фенолоксидазы, пероксидазы, полифенолоксидазы и каталазы от продолжительности хране- ния и характера предварительной обработки. Получены уравнения регрессии, характеризующие эти зависимости.

To reduce losses and increase the shelf life of fruit and vegetable products, chemical, biological, physical methods of processing raw materials are used before laying for storage. We have developed a technology for storing apples, which includes, before laying, processing fruits with a biological preparation based on walnut leaves and pericarp and a low- frequency electromagnetic field. The object of the study was apples of the Aydared variety, laid down for cold storage without treatment (control), with treatment only with a biological preparation and according to an improved integrated technology – a biological preparation + exposure to low-frequency EMF. It has been established that the biopreparation in combination with the treatment of EMF LF can have a significant impact not only on the duration of fruit storage, but also on their quality. The fruits that underwent complex processing retained an attractive appearance, were dense and juicy and had higher organoleptic indicators compared to the untreated fruits of the control sample. Kinetic dependences of changes in the activity of enzymes polyphenol oxidase, peroxidase, polyphenol oxidase and catalase on the duration of storage and the nature of pretreatment were revealed. Regression equations characterizing these dependencies are obtained.
