Authors: Wachnik Bartosz
Published: February 2022

Artificial Intelligence (AI) supports project management in industry projects increasingly more often. The article documents research results regarding the use of AI in Industry 4.0 projects. The aim of the article is to define the range of AI use in Industry 4.0 projects throughout their entire life cycle and to indentify the main stages of AI development in project management. Additionally, the article indicates the main barriers to AI use in project management identified in the studied projects. In order to identify and systemise the range of AI use, the Conceptual Framework of Using AI in Project Management presented in literature is applied. Research results indicate that we are in the early stages of AI use in projects. The studied projects use AI mainly in project administration, i.e. to complete the following tasks: simple automation of routine activities, support, and, to a very limited extent, in the area of project management, i.e. in identifying anomalies and predicting the phenomena where the anomalies will occur. The research uses the case study method, where four projects were studied: an ERP system upgrade, an implementation of an IT system supporting high-bay warehouse management, an implementation of an IoT as a data-collection sensor platform and an E-learning platform implementation. The study was conducted between 2019 and 2021, and covered the entire project life cycle, including its three stages, i.e. preparation, implementation and operation.

Published: February 2022

The purpose of this paper is to identify challenges and opportunities for exploring Lean approaches in managing instore logistics processes of a hypermarket, wherein data collection made to quantify the state of the system, methods, and instruments will be applied to improve picking and restocking processes between the two main stock areas, the store and the warehouse. This article reports on a case study work, comprising direct observation, and analysis of the data collected, which was developed in three main phases: identification and characterization of problems, improvements in management of stock and restocking information, and finally improvements in the picking and restoking processes and teams. After analysing the hypermarket, some problems were found such as a high percentage of non-productive time in restocking, a daily average of 132 products to be restocked, a lack of standardization of tasks in the warehouse, and outdated restocking management system. Therefore, there will be some proposals to change the restocking management system, the picking and restocking work method and the warehouse layout, which makes it possible to decrease stock breaks in the store by 17%, the number of employees dedicated to these processes from 14 to 11, and finally, to reduce 2 daily hours of non-adding value time. This work makes an innovative contribution to fulfil a lack of publications dedicated to hyper-market inbound logistics between the warehouse and the store. Thus, it reveals the significant importance of focusing on instore logistics to the point of sale, concerning the efficiency, the lean production, and social benefits to the retail hypermarket, from the reception of products in the hypermarket warehouse until they are placed on the store shelves.

Published: February 2022

Presently power control and management play a vigorous role in information technology and power management. Instead of non-renewable power manufacturing, renewable power manufacturing is preferred by every organization for controlling resource consumption, price reduction and efficient power management. Smart grid efficiently satisfies these requirements with the integration of machine learning algorithms. Machine learning algorithms are used in a smart grid for power requirement prediction, power distribution, failure identification etc. The proposed Random Forest-based smart grid system classifies the power grid into different zones like high and low power utilization. The power zones are divided into number of sub-zones and map to random forest branches. The sub-zone and branch mapping process used to identify the quantity of power utilized and the non-utilized in a zone. The non-utilized power quantity and location of power availabilities are identified and distributed the required quantity of power to the requester in a minimal response time and price. The priority power scheduling algorithm collect request from consumer and send the request to producer based on priority. The producer analysed the requester existing power utilization quantity and availability of power for scheduling the power distribution to the requester based on priority. The proposed Random Forest based sustainability and price optimization technique in smart grid experimental results are compared to existing machine learning techniques like SVM, KNN and NB. The proposed random forest-based identification technique identifies the exact location of the power availability, which takes minimal processing time and quick responses to the requestor. Additionally, the smart meter based smart grid technique identifies the faults in short time duration than the conventional energy management technique is also proven in the experimental results.

Authors: Britel Zineb , Cherkaoui Abdelghani
Published: February 2022

This paper provides a methodology to assess the maturity of an organization’s readiness for change based on the use of a Fuzzy Analytic Network Process and fuzzy linguistic evaluation maturity model. This anticipatory approach’s purpose is to evaluate the extent in which an organization is ready to implement a change initiative, in order to enhance supportive behaviors and identify improvement areas before engaging the change and thus reducing change adoption failure risks. A case study for the implementation of an Energy Management System according to the ISO 50001 Standard within a factory operating in the automotive sector is provided. Rather than the classical technical approach found in energy management maturity models, this approach offers an organizational perspective. The use of the Fuzzy Analytic Network Process allows the consideration of the interrelations between factors, while the use of fuzzy logic for the evaluation through linguistic variables helps in taking the uncertainty and imprecision of respondents into consideration. This approach serves as a decision support system for decision-makers by providing the organization’s readiness maturity level as well as the identification of improvement areas that will help ensure a successful implementation of the desired change initiative. In the conducted case study, the obtained maturity level refers to an average readiness for change for the implementation of the Energy Management System and requires the definition of an improvement roadmap, comprising the following elements: ensuring top management leadership and organizational commitment and involving employees as well as internal communication on the personal and organizational benefits of the implementation of an Energy Management System.

The results of the analysis of the dynamics of the average monthly values of hydrothermal climatic indicators on the territory of the Luhansk region (Northern Steppe of Ukraine) in the conditions of long-term climatic changes in precipitation (1882-2020) and air temperature (1837-2020) are presented. Statistical models — regression equations for determining temporary changes in the studied indicators are developed. Statistical analysis was carried out and patterns of dynamics of parameters of hydrothermal indicators were revealed within the framework of such stages: year, growing season; sowing periods of spring crops (April); harvest formation (May-June); post-harvest (July–August); sowing of winter cereals (September-October); cold period (November-March). A general trend towards an increase in the average annual precipitation and a high variability (CV > 25%) of the average monthly values in certain stages of the growing season were revealed. Probabilistic analysis of long-term data, using the method of constructing empirical and theoretical (analytical) security curves, revealed that the average monthly temperature during the sowing periods of early spring and winter crops 11-14 ℃ corresponds to 10% probability level, and 8.0–11.5 ℃ — 50%. In the same period, precipitation of 58-60 mm corresponds to a 10% probability level, and 30-40 mm corresponds to 50%. By analyzing the angles of inclination of trend lines, the dynamics of the average monthly values of precipitation and air temperature in the study area was studied and the distribution of the rate of increase or decrease in precipitation and temperature change was obtained. The generalization showed that the angle of inclination of trend lines is associated with the stage of the growing season. Fluctuations in average monthly temperatures correspond to fluctuations in the average monthly precipitation and are most noticeable in the periods of early spring sowing, crop formation and post-harvest. The average annual temperature in 1845-1935 on the territory of the region it is kept at the level of 8 ℃, and from 1935 to nowadays time it has been steadily increasing to 10 ℃. The revealed features of changes in the amount of precipitation over time can be used for further studies of the unevenness of atmospheric soil moisture, flood forecasting, changes in erosion activity, and the like.

The problem of accumulation and preservation of organic matter (OM) in the pedosphere is one of the main in the world research space. Using the search engine "Google Academy" (Google Scholar) of full texts of scientific publications (articles) on this topic over the past 5 years, showed that the query "carbon sequestration" received – 452,000 sources, and "soil carbon" sequestration " and "soil carbon sequestration potential" – 59,700 and 56,900 sources, respectively, while on request in Ukrainian "carbon sequestration" – 178 and "soil carbon sequestration" – 85. Under these conditions, it is important to inform the Ukrainian reader about the latest achievements of world science on the problem of C-sequestration and C-deposition of various types ecosystems and land use. The presented literature review considers the gradual development of theoretical, methodological and methodical bases for the development of organic matter stabilization models, mainly by a matrix of mineral soils (<020 and <50 μm) using linear least squares regression equations, analysis of limit values and other methodical approaches. Approaches to the assessment of soil carbon capacity (Carbon Protective Capacity), carbon saturation by the mineral matrix (Carbon Saturation, CS), C-saturation of the soil (Saturation Deficit), as well as the functional features of C-sequestration and C-deposition are considered. The existing methods for assessing the stabilization potential of the OM and the reality of the successful implementation of the International Initiative "4 in 1000: Soils for Food Security and Climate", adopted in December 2015, have been critically evaluated. Taking into account the world experience, the need to move to a three-member classification of soil particle size distribution in Ukraine is considered.

Soil pH is most routinely measured parameter among all others in soil chemistry laboratory. There are various methods developed for pH measurement, although we using only distilled water from the beginning. In Nepal, there do not have database for showing performance of the methods. The three methods namely; H2O, KCl and CaCl2 with their soil:solution ratios (1:1, 1:2 and 1:2.5) were used. The total 115 samples were collected randomly at a depth of 0-20 cm from the hill and terai regions of Nepal. The collected samples were analyzed following mentioned methods, separately. The various statistical tests (F-test, mean separation, correlation, and regression model) were performed for comparison. Moreover, model validation parameters were also calculated for relating H2O with electrolyte method. The three models linear, quadratic and cubic were used for this task. The result revealed the effect of methods on pH measurement was significantly different in the entire ratio. The pHH2O was 0.57, 0.56 and 0.67 units higher than pHCaCl2 in 1:1, 1:2 and 1:2.5 ratios, respectively. Whereas, 1.24, 0.99 and 0.95 units higher than pHKCl in respective ratio. Moreover, regarding timing to reach stable during measurement were in the order pHH2O (89.44 sec) > pHCaCl2 (54.29 sec) > pHKCl (33.08 sec). Similarly, relating modeling quadratic and cubic model showed nearly equal performance (lower RMSE, MAE and higher R2 and d) for predicting pHCaCl2 and pHKCl from the pHH2O in each soil solution ratio. The determined database can be useful for comparing used three different methods of soil pH measurement under Nepalese context.
Spatial and temporal variability of available phosphorus content in the arable soil layer according to different methods
Authors:   National Scientific Center «Institute for Soil Science and Agrochemistry Research named after O.N. Sokolovsky», Kharkiv, Ukraine, Kovalenko S. S.
Published: February 2022

The purpose of the article is to highlight the results of assessing the stability in time and space of the content of mobile phosphorus compounds in the soil within the arable layer on the land plots. The studies were carried out during 2018-2020 on two fields of the experimental farm "Grakovskoe" NSC "ISSAR named after O.N. Sokolovsky "in the Kharkiv region. The soil cover of one of the fields is made up of Chernozem podzolized (Chernic Phaeozem) in combination with Dark gray podzolized soil (Luvic Greyzemic Phaeozem), and the second field is Chernozem typical (Haplic Chernozem) with eroded and highly moistened varieties. Each field was divided into 24 plots, from which mixed soil samples were taken from 7 individual samples from a layer of 0–30 cm twice a season – in April–May and in October–November. On the soils of the podzolized row, a high amplitude of fluctuations in the pH values of salt was found during 3-year observations – from 4.4 to 5.2. As a result, the parameters of soil saturation with mobile phosphorus, determined by the methods of Chirikov and Machigin, were significantly different. In a field with chernozem, the typical measurement results for both methods were similar. The results of the analysis of the content of mobile phosphorus in the soils of the field according to the average values of the aggregate of individual samples did not show significant seasonal differences. However, on each of the fields, there were separate locations with higher values both according to the Chirikov method and the Machigin method, regardless of the sampling season. Along with this, in both fields there are locations where two methods of determination show different trends in the spatial distribution of the content of mobile phosphorus, which indicates the artificial nature of such heterogeneity. This confirms the hypothesis about the presence of a stable and temporarily artificial component of the spatial heterogeneity of the phosphate state of soils.
To the issue of the role of relief in the formation of spatial heterogeneity of soil parameters

Published: February 2022

The results of the study of the role of relief in the formation of the spatial heterogeneity of humus content, avalable compounds of phosphorus and potassium, the total content of nitrogen and pHH2O within the arable layer are highlighted. The study was carried out on two fields in the Kharkiv region in the zone of the Left-Bank Forest-Steppe of Ukraine. The soil cover of one of the fields is represented by gray forest (Haplic Luvisol) and dark gray podzolized (Luvic Greyzemic Phaeozem) soils, the second – by podzolized chernozem (Chernic Phaeozem) (including reclaimed) and dark gray podzolized (Luvic Gremizem) with eroded counterparts. According to the granulometric composition, all soils are heavy loamy. Relationships were found between the main indicators of soil fertility and the characteristics of the relief of the surveyed land plots, cartographic materials were created for the spatial distribution of nutrients using statistical methods of data processing. The existence of spatial heterogeneity of soil properties (Cv > 25 %) was confirmed and factors influencing the features of their spatial distribution were determined. It was found that the existence of heterogeneous landforms and, in particular, the presence of microdepressions in the surveyed areas, causes an uneven distribution of precipitation, which significantly affects the formation of heterogeneity of soil quality within the field – the content of nutrients (nitrogen, phosphorus and potassium) and soil pH. The results show that the soil at high relief points and in micro-depressions is better provided with humus and available phosphorus compounds. The zones of available potassium and nitrogen enrichment coincide with depressions in the relief. The reason for the distribution of nutrients is the migration of flows of substances, the intensity of which depends on the topographic features of the territory. It was found that the soil at higher parts of the field is characterized by pHH2O values close to neutral. Relative acidification of the soil was found in areas with a sharp slope of the surface. Based on the results, recommended to take into account the peculiarities of the spatial distribution of soil properties in the practice of applying fertilizers and chemical ameliorants.

فروغ فرخزاد بزرگ‌ترین و مهم‌ترین شاخصه شعرش ازنقطه ‌نظر ادب پایداری مبارزه با سنت است. فروغ با درون‌ مایه‌های مختلف اشعارش که در آن عصیان و پایداری در مقابل آنچه درونیاتش را مورد هجوم قرار داده بود، به تأثر از وضعیت و باورهای جامعه مردسالار و غیرتمند زمانش، در جرگه شاعران ادبیات پایداری قرار دارد؛ و در اشعارش با مضامین و مؤلفه‌های مختلفی از ادبیات پایداری مانند عصیان در مقابل هرچه که درونیاتش را مورد هجوم قرار داده، شکستن تابوها و گاه به سخره گرفتنشان، نقد و اعتراض و مقابله برابر سنت‌ها و گاه باورها و تاختن در مقابلشان، نقد مردسالاری به همراه آوردن واژگان زنانه و نیز جاری ساختن احساس زنانه، گاه در استعاره‎‌ها و گاه به شکل برهنه، می‌توان گفت در شعر فروغ فرخزاد بیش از پروین اعتصامی (که در اشعارش، با نوعی از شعر اعتراضی و پایداری آن‌هم از نوع مردانه‌اش روبرو هستیم.) مواجه می‌شویم؛ به‌طورکلی با بررسی شعر فروغ به‌عنوان یک شاعر پیشرو در رساندن صدای خاصِ زن نشان می‌دهیم که فروغ شاعر ادب پایداری می‌تواند لقب بگیرد. در اشعار فروغ، آمدن واژگان عامیانه و وارونه‌سازی کهن‌الگوها و همچنین سرودن ممنوعه‌ها و رد شدن از خط قرمزها، سنت‌‌شکنی، سنت‌گریزی، جسارت‌های لفظی، جسارت‌های معنوی، شکستن تابوها، شکستن افکار کهنه و خرافی، بیان آرمان‌شهر و ناجی و ترسیم چگونگی آن، شکستن یا برآمدن از افکار کهنه مذهبی و وارونه‌سازی پسندها، بیان تازه از اخلاق مطلق، بدی‌ها و خوبی‌ها، بیان دردهای انسان و دردهای انسانی، بیان مجموعه نا خوبی‌ها و سرچشمه‌های درد، آزادی و آزادگی و آرزوی رهایی از ناگواری‌های دنیا و دل ‌مردگی‌های آن و برداشتن نقاب از چهره دنیا که همه این‌ها از ایدئولوژی و جهان‌بینی و فلسفه هستی‌گرایانه فروغ پس از گذار از پوچ‌گرایی رخ می‌دهد و تمام این موارد را گاه با زبان کودکانه گاه زنانه گاه زبان انسانی دردمند بیان می‌دارد و با درک منابع درد و خطراتی که حیات معنوی روح فروغ و جامعه را در خطر انداخته به مقابله با آن می‌پردازد و در این پژوهش با توجه به یافته‌ها و شواهد شعری از دفاتر مختلف فروغ با روش توصیفی- تحلیلی و ابزار کتابخانه‌ای درصدد اثبات این ادعا برمی‌آییم.
المحور في النظرية التوليدية والنحو الوظيفي (دراسة تحليلية تطبيقية )
Authors: علي الهادي سليمان خيرالدين
Published: February 2022

نشأت الدراسات اللسانية متأخرة وظهرت نظريات غربيَّة تُعنى بدراسة اللغة دراسة موضوعية في مستوياتها المتعددة, ولعلَّ رائد هذه الثورة اللسانية هو ( لفرديناند دي سوسير) الذي أحدث ثورة جذرية في مجال الدراسات وعدَّ اللسان ظاهرة إنسانية.

ومن ثَمَّ جاء (نعوم تشومسكي) وكشف عن اللسانيات التوليدية التي أظهرت عيوب اللسانيات البنيوية وقصورها, إذ أكدت النظرية التوليدية التحويلية على القدرة اللغوية بوصفها وتفسيرها, وميزت بين القدرة اللغوية والاداء الكلامي.

والنظرية التوليدية التشومسكية قائمة على مبدأ عدم الفصل بين البنية والوظيفة, وتبني اللسان العربي ذلك؛ بل قبل ذلك, وجاءت نظرية المحور ضمن النظريات الفرعية في المرحلة الثالثة من مراحل النظرية التوليدية(مرحلة الربط والعمل), فيما تناول أحمد المتوكل نظرية المحور في النحو الوظيفي ضمن بعدها الاصطلاحي؛ لذلك جاء البحث للكشف عن مفهوم نظرية المحور عند تشومسكي في نظريته التوليدية وعند أحمد المتوكل الذي أسس لنظرية  النحو الوظيفي.

واقتضت الدراسة أن تكون بعد المقدمة والتمهيد في مبحثين؛ أما المبحث الاول فقد سبر أغوار بيان الجانب النظري لنظرية المحور في النظرية التوليدية وفي نظرية النحو الوظيفي, فيما قوَّم المبحث الثاني الجانب التطبيقي للنظريتين باستعراض عدة أمثلة توضيحية لمجموعة من الامثلة التي كشفت التمايز بين رؤية النظريتين, وتسهم في تقديم مادة علمية للباحثين في هذا الشأن, ومن ثَمّ ختم البحث  بعدَّةِ نتائج, والحمد لله على رعايته وعنايته وصلى الله على محمد وآل محمد.
أثر الإحالة في تناسق النَّصّ القرآني آيات الإحسان والإساءة مثالاً *

تغطي الإحالة في الدَّرس اللساني الحديث مساحة واسعة عند الاستعمال اللُّغوي؛ وذلك بوصفها اداة مهمة من ادوات الاتساق النحوي؛ إذ تعمل ومن خلال ادواتها ووسائلها على تماسك النّصّ / الخطاب الذي ترد فيها، وتعمل كذلك على تنويع الاساليب التي يمكن أن يلجأ إليها المنشئ / المتكلّم وكما تحفز المتلقِّي/ المخاطب على معالجة النّصّ / الخطاب عند التعامل معه ومعالجته؛ فتكون الإحالة في هذه الحالة ميدان يلجأ إليه كل من المنشئ والمتلقي لإبراز مقدرة كل واحد مهما في الانتاج من جهة المنشئ والاستعمال من جهة المتلقي.
NONEXISTENCE RESULTS FOR SEMI-LINEAR MOORE-GIBSON-THOMPSON EQUATION WITH NON LOCAL OPERATOR
Authors: ALI Hakem , GEORGİEV Svetlin
Published: February 2022

We study the nonexistence of global weak solutions to the following semi-linear Moore - Gibson-Thompson equation with the nonlinearity of derivative type, namely,$$\left\{\begin{array}{l}u_{ttt}+u_{tt}-\Delta u-(-\Delta )^{\frac{\alpha}{2}}u_{t}=|u_t|^p,\quad x\in \R^n,\quad t>0,\\u(0,x)= u_0(x),\quad u_t(0,x)=u_1(x), \quad u_{tt}(0,x)= u_2(x) \quad x\in \R^n,\end{array}\right.$$where $\alpha\in (0, 2],\quad p> 1,$ and $(-\Delta)^{\frac{\alpha}{2}}$ is the fractional Laplacian operator of order $\frac{\alpha}{2}$. Then, this result is extended to the case of a weakly coupledsystem. We intend to apply the method of a modified test function to establish nonexistence results and to overcome some difficulties as well caused by the well-known fractional Laplacian $(-\Delta)^{\frac{\alpha}{2}}$.The results obtained in this paper extend several contributions in this field.

The cobalt substituted Nickel-Zinc ferrites with the composition Ni0.95-xZn0.05CoxFe2O4, for x= 0.01, 0.02, 0.03, 0.04, 0.05 and 0.06 were synthesized by the soft chemical route method and were found to have cubic system of ferrimagnetic spinel using XRD. The grain sizes decreases significantly with the cobalt content (x) and are 1.62-1.36nm for x = 0.01 to 0.06 which are small enough to produce appropriate high density recording media. The particle size is found to be in the range 29-22 nm with the help of SEM. Their magnetic properties determined with VSM show the dependency on the exchange interaction due to the cobalt substitution between the metal ions of tetra and octahe.

In this work, we have studied security features of Nepali currencies of denomination Rs. 500 and Rs. 1000 of recent two series with the help of Video Spectral Comparator-6000. During examination, mostly ultraviolet, normal, transmitted and oblique light are used. We found nine different security features like fluorescence, water mark, micro text, security thread, intaglio print, see through registor, emboss, optically variable ink and latent image in this work. One feature, latent image is found to be completely removed in new series of both Rs. 500 and Rs. 1000 whereas new important security feature optically variable ink is introduced in new series of Rs. 500. Besides these two features, some are unchanged while some are modified.
The New Femme Fatale in 'Jennifer’s Body'
Authors: Alonso Palombi Alba
Published: February 2022

This paper offers an analysis of Jennifer Check from Diablo Cody’s film Jennifer’s Body (2009). It argues that the character of Jennifer advances the concept of the femme fatale by exploring the ways in which she both adheres to and challenges the trope, ranging from her outward appearance, her duplicity and her relationships with other female characters. This is contextualised through an overview of the longer history of the femme fatale, touching on biblical figures such as Eve (Adam’s wife), Lilith (the first wife of Adam who turned into a demon-mother) and Salome (daughter of Herod II who asked for the head of John the Baptist), and later characters such as Catherine Tramell from Basic Instinct (1992) to analyse the evolution of the trope in relation to different cultural moments. Additionally, the discussion emphasises the importance of the female re-appropriation of the figure, and differentiates it from the femme castrice. Finally, the paper establishes the new femme fatale, led by Jennifer Check, as a by-product of objectification and abuse that turns her into both victim and monster with a vendetta against those that made her.
Examining Patroclus’ role in Homer’s 'The Iliad', Shakespeare’s 'Troilus and Cressida' and Miller’s 'The Song of Achilles'
Authors: Campion J. S.
Published: February 2022

This paper argues that Patroclus plays a significant part in developing themes of war and nuancing the presentation of Achilles in Homer’s Iliad and works that it inspired – namely William Shakespeare’s Troilus and Cressida (1604) and Madeline Miller’s The Song of Achilles (2011). Although much analysis of these texts focuses on Achilles, Patroclus’ death is central to both themes and plot in each, and his changing characterisation and role within each narrative heavily impact the exploration of war and heroes. His presence nuances the characterisation of Achilles in each text, particularly when we adopt queer readings, and his death enables poignant explorations of grief and revenge. This paper will therefore reinvestigate these aspects of Patroclus’ importance in the Iliad, and examine the way in which his character has been received and utilised in a selection of more modern works.
Elegy for a Love Still Breathing
Authors: Campion J. S.
Published: February 2022

Within this poem, I wanted to explore the nuance within Achilles and Patroclus’ dynamic, taking a romantic interpretation of their relationship. After reading the Iliad by Homer, I have been fascinated by the ways in which these characters contrast each other; though both men are powerful fighters, Homer pays particular attention to Patroclus' kindness and often presents him as Achilles’ narrative foil. I was interested in exploring why a character such as Patroclus, who is depicted by his gentleness, would choose to remain by the side of somebody as prideful and aggressive as Achilles. This is something which other authors have previously presented in many different ways. For example, Madeline Miller’s novel The Song of Achilles (2011) presents Patroclus as a gentle individual who dislikes fighting, though within my own poem I wanted to acknowledge Patroclus’ capacity for violence when war necessitates that he kills enemy soldiers. Therefore, I experimented with the idea that Patroclus’ resentment at Achilles’ actions might manifest itself in the form of violent desires despite his great loyalty to, and love for, Achilles. To explore this conflict and bittersweet love within their relationship, I used the stereotypically romantic form of the sonnet. Furthermore, Patroclus’ sense of infatuation begins and ends the poem, as I wanted to highlight his tragic entrapment within his feelings for Achilles.
