Authors: Leonardi Flaviani Nathania , Astuti Niken Widi
Published: October 2023

The background of this research is to see that teaching is a profession with a high level of stress. When a teacher has a high level of stress, this will affect the individual teacher's well-being. This study aims to see whether there is a relationship between work stress and the psychological teacher's well-being. This research is a quantitative study using a purposive sampling technique, with a survey method using a questionnaire and g-form. The questionnaires used were the Job Stress Scale by Parker & Decotiis (1983) and Ryff's Psychological Well Being Scale by Ryff (1995). This study involved 385 teacher participants aged 21 to 60 years. This research was conducted for approximately 4 months starting from September 2022 to December 2022. The results of the correlation test using the Pearson Correlation Test, show that there is a negative relationship between work stress and psychological well-being. Negative work relationship means, the higher the teacher stress, the lower the teacher's psychological well-being.

Authors: FITRI WIJAYANINGSIH Nadia , MIFTAHURROHMAH Dinda , IQBAL Muhammad
Published: October 2023

In making spatial planning rules in the Special Region of Yogyakarta, the Regional Regulation (perdais) on Spatial Planning refers to Law No. 26 of 2007 on national spatial planning and DIY Provincial Regulation No. 2 of 2010 concerning the RTRW of DIY Province 2009-2029. The establishment of special rules regarding Spatial Planning of Sultanate Land and Duchy Lands is regulated in Special Regional Regulation No. 2 of 2017 concerning Spatial Planning of Sultanate Land and Duchy Land. This rule governs privileges in spatial planning, especially spatial planning related to Sultanate land and Duchy lands found throughout the DIY region. In addition, this regulation also regulates the spatial functions of the Sultanate and Duchy lands aimed at the maximum for the development of culture, social interests, and public welfare. The concept of spatial planning developed in the Perdais on Spatial Planning of the Sultanate and Duchy Lands is cultural, spatial planning, which is not the same as the spatial concept in western literature, which has been the reference for spatial planning. In-Law number 13 of 2012, it is explicitly stated that spatial planning in the Perdais is directly related to the land of the Sultanate and Duchy. But in the concept of thinking, the idea's substance covers the spatial planning of the DIY region comprehensively. It is directed to not conflict with the national spatial layout and the essence of DIY privilege.

Published: October 2023

A polycrystalline system corroborating experimentally observed microstructure is developed in this paper by employing cellular automata techniques. Moreover, through appropriate transition functions, microstructural changes accompanying dynamic recrystallization, a manufacturing technique associated with the production of a wide range of components, is simulated. The grain growth that characterizes this change is analyzed to explicate the trend in the temporal evolution of mean grain size and its kinetics. As opposed to a progressive increase in mean grain size, which generally typifies a conventional grain growth, in dynamic recrystallization it is observed that the mean grain size increases and decreases sequentially, thereby rendering an oscillating pattern. A perceptive investigation of the fluctuating trend unravels individual growth events, characterized by monotonic increase in mean grain size, whose kinetics follows the third-order power law. Additionally, the existing approach of modeling dynamic recrystallization is extended to facilitate unrestricted yet energetically favored growth of defect-free nuclei across their neighboring grains.

Published: October 2023

Simulation results on the employment resilience under a health emergency environment in Colombia South America are presented. The system is characterized by identifying the different relevant variables which are reflected in the causal and Forrester diagrams simulated through the VENSIM PLE x64 program.  Results show a resilient in the employment variable behaviour in terms of entrepreneurship and new companies generation, which reflects a potential economic development in the country under an uncertainty scenario. On the other hand, model accuracy is influenced by indicators changes along simulation time included in the analysis. Finally, it is concluded that the employment behaviour under the health emergency panorama is fluctuating but tends to increase in the last months in the time horizon simulation. However, it is highlighted that this situation can take another path if decision making is not adequate.

Published: October 2023

La pérdida somatosensorial de los amputados por debajo de rodilla (transtibiales) implica una serie de cambios en la postura estática bipedestada, lo que conlleva a la afectación del comportamiento del centro de presión (CoP). Se valida el desempeño de dos medidas convencionales del CoP (desplazamiento del CoP y velocidad del CoP) utilizadas para la caracterización de la estabilidad postural estática (EPE) empleando algoritmos de aprendizaje automático no supervisados tipo clúster, aplicados a dos grupos poblacionales: el grupo control corresponde a sujetos no amputados y el grupo de amputados a sujetos con amputación transtibial. Se precisan escenarios para cada uno de los algoritmos haciendo uso de la teoría de la información como método de clasificación, así mismo se realiza normalización de los datos a través de binning. En las dos medidas del CoP (velocidad y desplazamiento) se identificaron dos agrupaciones, correspondientes a los grupos examinados. Se observó una diferencia significativa entre los grupos, particularmente en la velocidad del CoP, de allí que sea la mejor variable discriminante. El presente estudio permite guiar a los profesionales interesados en el tema acerca de la variable a emplear al analizar la EPE, así como hacer uso de los datos para apoyar la parte de alineación de prótesis

Published: October 2023

Currently, there are aircraft tracking systems known as ACARS (Aircraft Communication Addressing And Reporting System), which are already able to provide certain information, however, this can only be used in very specific contexts, since information such as passengers or fuel used do not serve much to the maintenance area if you want to provide real-time support. Therefore, this research proposed the development of a prototype capable of real-time monitoring some of the systems of an aircraft and thus deliver the necessary information for good maintenance, monitoring, and support in real-time. For this case, the monitoring was performed on an RPAS (Remotely Piloted Aircraft System), since its acquisition or construction is more affordable; the flight prototype shed light on the behavior when acquiring and sending data frames inside the aircraft.

Published: October 2023

El café es uno de los productos agrícolas más comercializados internacionalmente y en Colombia, es el primer producto de exportación no minero-energético. En este contexto, la predicción del rendimiento de los cultivos de café es vital para el sector, ya que permite a los caficultores establecer estrategias de manejo del cultivo, maximizando sus ganancias o reduciendo posibles pérdidas. En este artículo, se abordan aspectos cruciales de la predicción del rendimiento de los cultivos de café mediante una revisión sistemática de literatura de documentos consultados en Scopus, ACM, Taylor & Francis y Nature. Estos documentos se sometieron a un proceso de filtrado y evaluación para responder cinco preguntas clave: variables predictoras, variable objetivo, técnicas y algoritmos empleados, métricas para evaluar la calidad de la predicción y tipos de café reportados. Los resultados revelan distintos grupos de variables predictoras que incluyen factores atmosféricos, químicos, obtenidos vía satélite, relacionados con fertilizantes, suelo, manejo del cultivo y sombras. La variable objetivo más recurrente es el rendimiento medido en peso de granos por hectárea u otras medidas, con un caso que considera el área foliar. Entre las técnicas predominantes para predecir el rendimiento se encuentran la regresión lineal, los bosques aleatorizados, el análisis de componentes principales, la regresión por conglomerados, las redes neuronales, los árboles de clasificación y regresión y las máquinas de aprendizaje extremo, entre otras. Las métricas más comunes para evaluar la calidad de los modelos predictivos incluyen R², RMSE, MAE, MAPE, MRE, error estándar, coeficiente de correlación de Pearson y desviación estándar. Por último, las variedades de café más estudiadas son robusta, arábica, racemosa y zanguebariae.

Nursing Educators’ Experiences and Expectations of Research Production at a Faculty of Health Sciences: A Qualitative Study
Authors: Shatimwene Gelasius Panduleni , Ashipala Daniel Opotamutale
Published: October 2023

Research production remains one of the most important tools to predict the likely number of future outputs for a set of researchers. Nursing educators have expectations when they enter an academic institution; however, if these expectations are not matched with their experiences, then their research production will be hampered. The purpose of this study was to explore nursing educators’ expectations and experiences regarding research production at the Faculty of Health Sciences at a national university in Namibia. The study used the qualitative approach with an explorative, descriptive and contextual design. Eighteen nursing educators from the School of Nursing and Public Health participated in the study. Participants were chosen by using a convenience sampling method. Data were collected through semi-structured interviews between June and September 2022 and were analysed using thematic analysis for recurring themes. The following themes emerged from the data analysis: individual research output and role expectations; institutional factors affecting research production; and corrective measures to improve research production. These findings demonstrate that there is a significant need to support the production of quality research of nursing educators by addressing the requirements of the academic and research staff so as to maximise the impact of their research and establish the University of Namibia as a renowned international research institution. This can be achieved through creating an opportunity for hosting research seminars, and by providing adequate financial support to academics and research staff to maximise the impact of their research. The findings of this study can be used to develop baseline data, which can enable a “point-in-time” snapshot of individual activity. This will enable consolidation of metrics on research activity up to faculty, school and institutional performance that is geared towards improving research production among academics, as well as the development of policies that support such production.

electromagnetic force pulses are forces of mutual repulsion between the anchor and the inductor. Under their action, the anchor is shifted towards the cleaned surface of the affected object and elastic vibrations are transmitted to it. In electro-pulse interaction systems, the duration of the energy accumulation process, and then its release in extremely small time intervals, allows to obtain the maximum possible values of mechanical impulse action on the surface of the affected object. The maximum operating voltage on a capacitive energy storage is capable of reaching 5 kV and higher. Electro-pulse interaction systems are shock-type devices. Compared with other devices of similar purpose (vibrators, electromagnetic or pneumatic shock mechanisms), they have no competition in terms of cleaning efficiency.
DEVELOPMENT OF A FULL-ORDER LUENBERGER OBSERVER FOR THE STATE VECTOR OF A CABLE SECTION WITH ENHANCED PARAMETRIC ROBUSTNESS
Authors:   Gazprom transgaz Tomsk LLC, Tomsk, Russia, Rakov I. V.
Published: October 2023

In addition, in the Russian Federation, 75 % of oil-producing wells in operation at old fields are low- to medium-flow rate wells. One way to increase the profitability of oil production from low- to medium-flow rate wells using ESPs is to reduce the power consumption of the Submersible Electric Motor (SEM) by switching the ESP from a scalar open-loop control system to a sensorless vector control system. To implement the vector control system for ESPs, it is necessary to develop a methodology for identifying the parameters of the electrical equipment in the power channel of the ESP, as well as to implement a full-order observer of the SEM vector state variables to create a feedback channel for angular speed. One of the electrical components in the ESP power channel that affects the accuracy of the SEM vector state variable estimation is the power cable, which can reach up to 5 km in length. Such a long cable length results in the output voltage at the cable end being significantly different in amplitude and frequency from the measured input voltage, and the cable parameters themselves change as the temperature of the well varies depending on the depth. Failure to estimate the output voltage of the cable will result in incorrect estimation of the torque and angular speed of the SEM, which, in turn, may cause the angular speed of the SEM to oscillate and the ESP to trip at the bottom of the well. Due to the above factor, the development of a full-order observer for the vector state variables of the cable line with increased parametric robustness is a relevant and timely task

Resonance Theory of Vibrational Polariton Chemistry at the Normal Incidence
Authors: Ying Wenxiang , Taylor Michael , Huo Pengfei
Published: October 2023

We present a theory that explains the reso- nance effect of the vibrational strong coupling (VSC) modified reaction rate constant at the normal incidence of a Fabry-Pérot (FP) cavity. This analytic theory is based on a mechanistic hypothesis that cavity modes promote the transition from the ground state to the vibrational excited state of the reactant, which is the rate-limiting step of the reaction. This mechanism for a single molecule coupled to a single-mode cavity has been confirmed by numerically exact simulations in our recent work in [J. Chem. Phys. 159, 084104 (2023)]. Us- ing Fermi’s golden rule (FGR), we formulate this rate constant for many molecules coupled to many cavity modes inside a FP microcavity. The theory clearly ex- plains the resonance condition for the observed VSC effect and provides a theoretical explanation of why only at the normal incident angle there is the reso- nance effect, whereas for an oblique incidence, there is no apparent VSC effect for the rate constant even though both cases generate Rabi splitting and forming polariton states.
Rh(III)-Catalyzed [4+3] Annulation: Temperature Dependent Ste-reodivergent Synthesis of Point-Planar Chiral Ferrocene Fused Azepines

Published: October 2023

Planar chiral ferrocenes are extensively investigated structures in asymmetric catalysis, materials science, and medicinal chemistry. Although, the synthetic approaches for six-membered fused planar chiral ferrocenes are well-established, the construction of a seven-membered fused ring via [4+3] annulation has remained unexplored and seems to be challenging. Allenes are valuable synthons and well explored for [4+1] and [4+2] annulation but not yet explored for [4+3] annulation. Herein, an efficient rhodium-catalyzed temperature-dependent stereodivergent [4+3] annulation reaction has been devel-oped for the synthesis of novel seven-membered ferrocenylazepines via C-H activation of substituted ferrocene-p-tosylamides with allenes. At room temperature, Rh-catalyzed [4+3] annulation selectively offered one diastereomer (>20:1 dr), whereas at 60 ºC, another diastereomer was obtained exclusively with >20:1 dr. Further, [4+3] annulation reaction in the presence of a chiral RhCpX catalyst (2.0 mol %) yielded chiral ferrocenyl azepines in 56% yield and up to 90:10 er. Mecha-nistic investigations by control experiments and isotopic labeling study suggested that the reaction proceeds via a formation of a σ-bonded rhodacycle, having low energy due to less steric repulsion between the phenyl ring of allene and Cp*(pentamethyl cyclopentadienyl), which upon reductive elimination offered kinetically controlled diastereomer at room temperature. Under heating (60 ºC) conditions, kinetically controlled diastereomer undergo CH-allylic isomerization to af-ford completely thermodynamically controlled diastereomer, which has also been observed experimentally and computa-tionally for isolated kinetically controlled diastereomer.
Exploring Natural Dye and Bioactive Secondary Metabolites in Lonchocarpus Cyanescens Benth (Fabaceae) Plant Using Liquid Chromatography-High-Resolution Mass Spectrometry and Compound DiscovererTM Software
Authors: Amit Tanvir , Colón Luis
Published: October 2023

Lonchocarpus cyanescens Benth is a native African plant commonly known as "African Indigo" or "Indigo Vine" because locals extract dyestuff from its leaves that gives it a brilliant indigo-like hue. Several scientists have reported this plant to contain indigo dye; however, there has been no evidence to justify their claim. Therefore, the primary dye component(s) responsible for the indigo-like hue has been scientifically unexplored. In this study, we utilized UV-Vis and HPLC-DAD-ESI-HRMS (OrbitrapTM) techniques to identify the main chemical compound(s) responsible for the color of the dyestuff. To our surprise, the presence of indigo dye was not detected in the isolated dye extract; we discovered that crystal violet dye and crystal violet-like molecules are present in the extract, which can be responsible for the blue color observed. In addition to its natural dye-producing capability, this plant is used by local traditional healers to heal ailments including ulcers, arthritis, intestinal disorders, etc. Many scientists have proved that the effect of this plant extract on many of these disease states was justified; however, the molecular identities of the compounds responsible for the plant's medicinal value have been unexplored. Therefore, we also analyzed the leaf extract of L. cyanescens and identified several chemical compounds having structural similarities to active drug compounds. The details of our findings will be the focus of our research work.

Published: October 2023

Methods to form carbon-carbon bonds efficiently and with control of stereochemistry are critical for the construction of complex molecules. Cross-coupling reactions are among the most efficient and widely used reactions to construct molecules, with reactions enabling the retention or installation of chirality as recent additions to this powerful toolbox. Sulfones are robust, accessible organic electrophiles that have many attractive features as cross-coupling partners, however since the first example of their use in 1979, there have been no examples of their use in enantio-selective, -specific or -convergent cross-couplings. The high acidity of sulfones makes it unclear whether this transformation is even possible outside tertiary systems. Herein we report the enantiospecific cross-coupling of cyclic sulfones and Grignard reagents. Up to 99% chirality transfer is observed despite the strong basicity of the Grignard components. In situ monitoring reveals that the cross-coupling is kinetically competitive with competing deprotonation, resulting in a highly enantioselective transformation.

Authors: Atemasova Т. , Ronkin V. , Savchenko G. , Sinna O.
Published: October 2023

The remnants of natural steppes in Northeastern Ukraine are represented in small areas, interconnected by riverbeds or large, extensive ravines and gullies. The presence of a large number of plant and animal species listed in the Red Book of Ukraine is the basis for granting of national protection status to these territories. The total territory of the prospective National Nature Park (NNP) “Skhidnyi Steppe” includes three clusters: Vovchanskyi, Burlutskyi and Kupyansko-Shevchenkivskyi, its total area is 22272.0 hectares. The future park covers the existing reserves "Vovchansky" and "Siverskodonetsky", the regional landscape park "Velykoburluk Steppe" (4 segments), and several reserves of a small area. In addition to the steppe areas, it is planned to include forests and meadow areas. The flora and fauna of the territory to be protected are of high conservation value: 25 species of vascular plants are listed in the Red Book of Ukraine; 63 species are listed in the Red List of Kharkiv region; 17 species of chalk outcrops and chalk steppes are relics; 49 animal species are listed in the Red Book of Ukraine; 100 animal species are listed in Annexes 2 and 3 of the Berne Convention, 27 bird species are included in the lists of Bonn Convention; 33 animal species are in the List of rare species and species requiring protection in the Kharkiv Region. In addition, the proposed park hosts groups of 11 formations included in the Green Book of Ukraine and 16 habitats in need of protection under the Berne Convention. The purpose of the establishment of the National Nature Park “Skhidnyi Steppe” is the protection of unique natural areas in Northeastern Ukraine, namely, the last remnants of steppe and meadow ecosystems and forests in steppe gullies, which are an integral part of the gully steppe macrocomplex. The primary task of the future national park is to protect the grasslands. The next step is the restoration of pasture ecosystems as habitats for rare and endangered steppe species. This paper describes the planned NNP as of early 2022; it does not reflect changes caused by the hostilities that began in February 2022 and continue in the northern part to date.

Authors: Suhesty Citra , Dinutanayo Wimba Widagdho , Tuntun Maria , Hidayat Hidayat
Published: October 2023

SARS-CoV-2, a lung-damaging virus, is what causes COVID-19. While a decline in lymphocyte counts suggests immune system harm, a rise in neutrophil counts reflects the severity of the inflammatory response. A high NLR value results from an increase in neutrophils and a decrease in lymphocytes. On the other hand, when plasmin breaks down fibrin to dissolve blood clots, it creates pieces called D-dimers. ARDS is predicted by an elevated D-dimer level. The study's objective was to ascertain how the severity of COVID-19 patients at Dr. H. Abdul Moeloek in 2021 related to NLR and D-dimer levels. Analytical research with a retrospective design is being conducted. The Rank Spearman correlation test and Pearson Chi-Square analyzed medical record data for COVID-19 patients. The study was carried out in Dr. H. Abdul Moeloek in June 2022. 205 COVID-19 patients who underwent NLR and D-dimer testing and were categorized based on the severity of the condition served as the study's subjects. The test findings revealed a substantial connection between NLR and D-dimer (r=0.583), demonstrating a strong and favorable link. NLR and illness severity showed a significant relationship (r=0.49). D-dimer and illness severity also showed a strong connection (r=0.51).

Published: October 2023

Introduction: To perform a technical action, the elite judo athlete examines the direction of attack relative to the opponent's body position. This study aimed to analyze and compare the most frequent and effective attack directions carried out by male Olympic medalists. Materials and Methods: A sample of 112 male medalists performed 3,664 attacks in four Olympic tournaments (2004–2016). ANOVA (one factor) determined inter and intra-Olympic comparisons, followed by the post hoc Bonferroni test (p< 0.05). Eta squared η2 and Cohen's d calculated the effect size, respectively. Results: Olympic medalists oriented their attacks principally in right forward (30.5±11.3%), left forward (29.9±10.5%), left backward (18.8±8.1%), and right backward (15.8±6.1%). The effectiveness of right forward (25.7±13.1%) and left forward (26.2±12.5%) dominates left backward (20.5±10.1%) and right backward (15.5±9.7%), respectively. In terms of frequencies and effectiveness, the contribution of secondary directions is negligible. Conclusions: Attacking in eight orientations made the defense vulnerable. Beside the uncertainty and unpredictability, they created more points of imbalance to overcome defensive issues.

The COVID-19 outbreak in 2020 caused continuous damage worldwide, especially the smart tourism industry was hit directly by the blockade of sky roads and restriction of going out. At a time when overseas travel and domestic travel have decreased significantly, the number of tourist hotels that are closed and closed due to the continued deficit is increasing. Therefore, in this study, licensing data from the Ministry of Public Administration and Security were collected and visualized to understand the operation status of the tourism and lodging industry. The machine learning classification algorithm was applied to implement the business status prediction model of the tourist hotel, the performance of the prediction model was optimized using the ensemble algorithm, and the performance of the model was evaluated through 5-Fold cross-validation. It was predicted that the survival rate of tourist hotels would decrease somewhat, but the actual survival rate was analyzed to be no different from before COVID-19. Through the prediction of the business status of the hotel industry in this paper, it can be used as a basis for grasping the operability and development trends of the entire tourism and lodging industry.
Fashion: aesthetic and social functions

Published: October 2023

The unity and interrelation of aesthetic and social components of fashion from the standpoint of philosophy is emphasized. The boundaries of the concept of «fashion» are clarified from the point of view of modern science, in relation to which its aesthetic and social functions were analyzed – fashion in the broad sense of the word, in other words, not only vestigial – related to the style of clothing. An excursion into the history of fashion as a marker of social inequality and an indicator of social inequality with attention to the gender aspect of this issue is carried out. The modern problems of the interpenetration of aesthetic and social as fashion changes are touched upon. Much attention is paid to sources related to the Internet, mass media, advertising. It is concluded that in the context of fashion, aesthetics helps society and individuals to build a particular system of views, while society, through certain value attitudes, acquires certain aesthetic ideas.
Capable of Obtaining Potable Water from Air with Solar Energy A Software and Hardware Supported System Suggestion

Fresh water is one of the most important resources consumed. However, droughts due to global climate change, rapid population growth and increasing construction sector activities and the lack of importance to protect fresh water resources during these activities increase the problems related to water. With this study, it is aimed to raise awareness of people about the protection of fresh water resources. For this purpose, a software and hardware supported system has been developed to obtain fresh water by cooling and condensing the humidity in the air with the help of thermoelectric modules and fans. The developed system can automatically become active or passive according to the weather conditions and uses less energy than its counterparts. The system, which can also operate independently of the grid with solar energy, can also purify the water obtained by producing ozone gas with the effect of static electricity on the surface where water droplets form and make it drinkable.

Relatedness and kinship structure in matrilines are a potential source of social stability. The current study aimed to analyze the extant pedigrees of 6 living matrilines in different field cages to assess rates of cross-generational inbreeding and loss of genetic variation over time.
All 6 matrilines showed increasing levels of inbreeding over generation time, although the rates of increase were different. The female-to-male-adult sex ratio was correlated with average matriline inbreeding levels, while the number of adult males was positively correlated with average matriline
genetic diversity. Over five times more paternal half-sibs than maternal half-sibs were present because paternity had been restricted to a few males yearly. Therefore, the relatedness through the paternal lines was over five times greater than that of the maternal lines. Overall, each matriline
lost low to moderate levels of genetic variation with time. The current rates of gene flow between field cages by cross-fostered infants have not stopped inbreeding within these matrilines or loss of diversity due to genetic drift. This situation probably developed because translocated animals,
especially males, may not breed successfully. Only 4 of the 22 translocated individuals, all females, eventually reproduced, resulting in 13 offspring and generating an overall breeding success of 0.59 across all 6 study matrilines. However, even this low rate of reproduction by the translocated
animals reduced inbreeding and kinship among matrilines and increased genetic heterogeneity in the matrilines. Based on this study, we propose several colony management strategies, including equalizing adult sex ratios to increase the effective population size in the field cages, increasing
the number of cross-fostered infants, and relying more on multigenerational pedigree data to aid the alignment of genetic and behavioral management techniques.

Özet: Uluslararası öneme haiz olan Uluabat Gölü, pek çok canlı türü için yaşama, barınma ve üreme alanı oluşturmaktadır. Uluabat Gölü’nü besleyen en önemli su kaynağı Mustafakemalpaşa (MKP) Çayı’dır. Yapılan bu çalışmada ülkemiz için önemli bir sulak alan olan, Uluabat Gölü’nü besleyen, MKP Çayı’nın su kalitesi değerlendirilmiş, Uluabat Gölü’ne taşınacak kirlilik yükleri hesaplanmıştır. Su kalitesi belirlenirken Ekim 2017 – Eylül 2019 dönemlerini kapsayan süreçte biri memba diğeri mansap olmak üzere akarsu üzerinde belirlenen 2 farklı örnekleme noktasında mevsimsel olarak su kalitesi izlenmiştir. İzlenen su kalitesi parametreleri nitrat azotu (NO3-N), toplam azot (TN), fosfat fosforu (PO4-P), toplam fosfor (TP), kimyasal oksijen ihtiyacı (KOI) ve biyolojik oksijen ihtiyacı (BOI) olup, bu parametrelerin mekânsal ve zamansal değişimleri irdelenmiştir. Çalışma sonucunda, 2017-2019 su yıllarını kapsayan süreçte MKP Çayı yıllık ortalama debi değerinin 15.94 m3/s olduğu, toplam kirletici yükleri büyüklük sıralaması KOI>BOI>TN>NO3-N>NH4-N>TP>PO4-P şeklinde olduğu tespit edilmiştir. MKP Çayı’nın yoğun kirliliğe maruz kaldığı, Yerüstü Su Kalitesi Yönetmeliği’ne (YSKY) göre III. sınıf su kalitesine sahip olduğu belirlenmiştir. Bu durumun Uluabat Gölü’ne yoğun bir kirlilik taşıdığı kaçınılmaz bir gerçektir.

The operation of obtaining cylindrical products with a titling pad made of titanium alloy VT6 is viewed in the article. The operation involves impacting a bar blank made of titanium alloy VT6 with the use of a punch having sloped edge. When obtaining parts having titling pad made of difficult-to-form alloys, it is necessary to formulate the modes of technology. It is required to specify the rates of deformation and the impact of contact friction on the kinematics of the material flow and the force of shape change to assess the capabilities of the process performed by CAE modeling. Therefore, the simulation of obtaining cylindrical products with a titling pad made of titanium alloy VT6 was performed in the DEFORM modeling program. The influence of the speed conditions of the operation on the change in the values of stress intensities in the product was found. The dependences of the influence of the angles and rates of deformation on the landing force are revealed. The results of theoretical studies obtained during the simulation were summarized. A regression analysis of the results obtained during the simulation was performed. Based on the simulation results, expressions for estimating the intensity of stresses are obtained. The results of regression modeling are in good agreement with the results of computer modeling. Using quantitative modeling results, a regression assessment of the force was taken. Regression equations in natural values are obtained for the assessment of the impact of key process parameters during setup, which can be useful directly when assigning technological modes of titanium alloy blanks setup. The results can be used in the implementation of manufacturing technologies for parts with flange seals, characterized by the best strength characteristics and good load resistance.
