Published: April 2024

Distributed generation (DG) is an approach that involves adding decentralized power generation within a distribution network. Distributed generation systems can reduce transmission losses, increase the reliability of energy supply, minimize carbon emissions, and enable the active participation of consumers in energy production. However, with the increase in distributed generation, electric power systems face new challenges in maintaining operational reliability and safety. Disruptions such as short circuits or overcurrent can occur in the system, and appropriate protective responses are required to protect the power grid from more significant damage. The addition of DG also causes the short circuit current to vary and results in system protection coordination having to be redone. Carrying out coordination will take a long time. This research uses modeling and simulation of a distributed generation system with various operating conditions and works adaptively according to changes in the system due to the addition of DG. The results obtained from the simulation are used in neural network training to study the relationship patterns between directional overcurrent relays (DOCR) parameters and system operating conditions. The backpropagation algorithm is used in the Artificial Neural Network (ANN) training process. The training process utilizes the maximum Short Circuit Current (ISC) input obtained through generation, fault location, and fault type. Time Dial Setting (TDS) and Ipickup values are used as ANN training targets. After testing, the results obtained are in accordance with the target data. The efficacy of this method is further demonstrated through ETAP simulations, which confirm that ANN is a suitable approach for modeling adaptive and optimal relay coordination systems.

Published: April 2024

This study evaluates the performance of a 36 Volt 10 Ah battery in an electric bicycle with a 350-Watt Brushless DC (BLDC) motor as an environmentally friendly alternative to overcome the negative impacts of motorized vehicle use in Indonesia. In addition, this study measured the State of Health battery’s value of internal resistance, which is different from other studies that use capacity fading. With a focus on maximum travel distance and travel time, experiments were conducted without load and with a 70kg load. The no-load test was conducted only once, resulting in a travel time of 600 minutes and a distance of 330.1 Km. Although the battery was not discharged, the results were not in line with expectations, so the no-load test was only conducted once. In the 70kg load test, six trials were conducted with variable measurements of distance, battery voltage, and battery resistance. Results showed variations in distance between 50.7 km and 53.1 km, and travel time between 151 and 160 minutes. The battery voltage varied from 31.316 Volts to 31.850 Volts. The resistance in the battery also showed an increase of about 0.0001 ohms from 0.1132 ohms to 0.1139 ohms. Overall, the results from the study showed that as time and usage progressed, the battery voltage and internal resistance values tended to increase, while the distance and travel time tended to decrease. The internal resistance measurement method proved to be effective in assessing battery health as the State of Health value decreased throughout the experiment.

Published: April 2024

Water covers about 70% of the earth’s surface and is essential for life (Wang et al., 2020), out of which only 3% is fresh and only 0.5% drinkable. Water is single largest component of human body and comprises nearly 60% of it. (Zhou & Chen, 2018). Its excessive and ever increasing use in all fields of life has made Fresh water shortage a global threat. Only 33% of the world's total population has access to standard-quality freshwater. Water is being polluted from a variety of sources, from domestic to industrial level. Contaminants in this polluted water involve heavy metals as well that leads to serious adverse effects on the lives to which the water is being served (Obinna & Ebere, 2019). Considerable fraction of this polluted water is being used as untreated in irrigation (Sarwar et al., 2020).This contaminated water has high concentration of Nitrogen and Phosphorus , and that’s why its use in irrigation is increasing gradually (Zhang & Shen, 2019) . As this waste water is contaminated with heavy metals including; Arsenic (As), Cadmium (Cd), Nickel (Ni), Mercury (Hg), Chromium (Cr), Zinc (Zn), and Lead (Pb) and has become a serious health issue for men, plants and animals. (Rehman et al., 2018). These heavy metals present in waste water are not only toxic but are non-biodegradable which make their presence even worse. When this heavy metals containing water is used for irrigation, they enter into the plants and vegetables, where they do not have any significant biological role but causes various adverse effects to them (Chaoua et al., 2019). Their bioaccumulation in plants has reported to inhibit the growth of the plants (Kamran et al., 2020) Bioaccumulation of various heavy metals such as arsenic, mercury, lead and chromium will tear down the metabolic processes involved in the human body. These fruit based absorbents act as precursor of activated carbon and contain other functional groups that helps to adsorb the heavy metals from water. These functional groups (- COOH, -OH, - NH2) present in bio absorbents make a thin film of heavy metals on them (Mallampati et al., 2015) 2011). In this study, peels of different plants i.e Bitter Apple, Cucumber, Persimmon, unripe orange and activated carbon from used dry cell were used. Organic functional groups present in them adsorb the heavy metals and reduces their concentration. Moreover, Activated Carbon which has proved to be a versatile adsorbent and a potential candidate in treatment of waste water was also used. Results from all above materials were separately obtained and comparatively analyzed which was very helpful in explaining their efficiency.

Published: April 2024

Enzymes are reported to catalyze reactions by generating electric fields that promote the evolution of the reaction in the active site. Although seldom used outside enzymatic catalysis, electrostatic preorganization theory and the language of electric fields can be generalized to other biological macromolecules. Here, we calculate the electric fields generated by the residues of human voltage-gated sodium channel Nav1.7. We show that in the inactivated state, and in the absence of an external bias (transmembrane potential), residues in the selectivity filter and outer-ring of carboxylates, as well as a few others, generate strong electric fields that assist in Na+ binding and permeation. We validated these results by characterizing water alignment in the channel pore and computing the free energy profile of pore Na+s. We found that areas with stronger electric fields (stronger water alignment) correlates with Na+ minimum-energy sites. Additionally, we show that Nav1.7’s residues exert an electric field aligned along the S4 helix in each domain, assisting channel state transitions. Interestingly, we observe that the four domains of Nav1.7 do not contribute equally to these fields, revealing a functional difference in the homologous domains. Overall, our results show that the residues in Nav1.7 generate preorganized electric fields that facilitate gating, ion binding and permeation, thereby expanding electrostatic preorganization theory to ion channels.
Sulfur-Bridged Diazulenylmethyl Cations: Formation of Charge-Segregated Assembly with High Charge-Carrier Mobility

Published: April 2024

Sulfur-bridged diazulenylmethyl cations were synthesized and exhibited high stability even under basic conditions (pH 10) due to the delocalization of positive charge over the whole pai-conjugated skeleton. As a result of the effective delocalization and the absence of orthogonally oriented bulky substituents, the cationic pai-conjugated skeletons formed a pai-stacked array with short interfacial distances. A derivative with SbF6 as a counter anion formed a charge-segregated assembly in the crystalline state, rather than the generally favored charge-by-charge arrangement of oppositely charged species based on electrostatic interactions. Theoretical calculations suggested that the destabilization caused by electrostatic repulsion between two positively charged pai-conjugated skeletons is compensated by the dispersion forces. In addition, the counter anion SbF6 played a role in regulating the molecular alignment through F…H-C and F…S interactions, which resulted in the charge-segregated alignment of the cationic pai-skeletons. This characteristic assembled structure gave rise to a high charge-carrier mobility of 1.7 cm2V-1s-1 as determined using flash-photolysis time-resolved microwave conductivity and photocurrent measurements.

Published: April 2024

Active learning (AL) is a specific instance of sequential experimental design and uses machine learning to intelligently choose the next data point or batch of molecular structures to be evaluated. In this sense it closely mimics the iterative design-make-test-analysis cycle of laboratory experiments to find optimized compounds for a given design task. Here we describe an AL protocol which combines generative molecular AI, using REINVENT, and physics-based absolute binding free energy molecular dynamics simulation, using ESMACS, to discover new ligands for two different target proteins, 3CLpro and TNKS2. We have deployed our generative active learning (GAL) protocol on Frontier, the world’s only exa-scale machine. We show that the protocol can find better binders compared to baseline, a surrogate ML docking model for 3CLpro and compounds with experimentally determined binding affinities for TNKS2. The ligands found are also chemically diverse and occupy a different chemical space than the baseline. We vary the batch sizes that are put forward for free energy assessment in each GAL cycle to assess the impact on their efficiency on the GAL protocol and recommend their optimal values in different scenarios. Overall, we demonstrate a powerful capability of the combination of physics-based and AI methods which yields effective chemical space sampling at an unprecedented scale, of immediate and direct relevance for modern, data-driven drug discovery.

Published: April 2024

Nanostructured metamaterials can offer optical properties beyond what is achievable in conventional media, such as negative refraction or sub-wavelength imaging. Due to their structural anisotropy, the class of high aspect ratio metamaterials is of interest for the possibility of achieving hyperbolic behavior, i.e., materials with both metallic and dielectric optical response based on the excitation direction. Although widely investigated numerically, the fabrication of tailor-made metamaterials is very complex or often beyond range using current technology. For wire metamaterials composed of aligned metallic nanowires in a dielectric matrix, since the free carrier concentration in metals is fixed, light-matter interaction cannot be adjusted/ changed anymore after fabrication. Here, we introduce high aspect ratio metamaterial based on plasmonic ITO nanotubes with controllable hyperbolic response. The synthesis is achieved by a scalable template-based liquid-phase technique. Our tuning mechanism is based on controlling the carrier density in ITO via oxygen vacancy concentration. The process is reversible, the photonic features are activated by creating oxygen vacancies and can be switched off by filling them up again. Further, it is shown that the carrier concentration can also be controlled via a static electric field. Optical simulations support the experimental findings and highlight the parameters that determine the optical response of the metamaterial.

A comparative analysis of dorothy orem's self-care deficit theory and sister callista roy's adaptation model
Authors: Muhammad Tariq
Published: April 2024

This paper provides a comparative analysis of Dorothy Orem's Self-Care Deficit Theory and Sister Callista Roy's Adaptation Model in the context of nursing practice. Orem's theory underscores the importance of self-care and the nursing role in addressing self-care deficits, focusing on concepts like self-care agency and deficit. Conversely, Roy's model views individuals as adaptive systems, highlighting the role of nursing in facilitating adaptive responses to environmental stimuli. Through a detailed examination of their theoretical perspectives, assumptions, and key concepts, this analysis elucidates the similarities and differences between the two theories. While Orem's theory concentrates on self-care deficits and the nurse's supportive role, Roy's model takes a broader view, emphasizing adaptation and holistic well- being. Understanding these theories' distinct perspectives can empower nurses to tailor interventions effectively, promoting better patient outcomes across diverse healthcare settings.

Published: April 2024

The authentication of higher quality milk such as goat milk (GM) from the lower price of
cow milk (CM) is a big issue in the milk industry, because unethical producers may get
economic profits from the adulteration practice. This study intended to apply Fourier
Transform Infrared (FTIR) spectroscopy and chemometrics for the authentication analysis
of GM from CM. The characterization of CM and GM was performed by determining
fatty acid composition using gas chromatography. The binary mixtures of GM and CM
were prepared for making calibration and validation models and were subjected to FTIR
spectral measurement using an attenuated total reflectance (ATR) accessory. The model
was optimized by selecting multivariate calibrations of partial least square regression
(PLSR) and principal component regression (PCR) along with spectral modes (normal and
derivatives) and wavenumbers regions. The results showed that absorbance values at 2nd
derivative spectra at wavenumber regions of 1500-800 cm-1
could provide the best
accuracy and precision of the developed model. Principal component analysis (PCA) at
selected wavenumbers and linear discriminant analysis (LDA) at 3800-800 cm-1 could
discriminate authentic GM and GM adulterated with CM without any misclassification
objects observed. It concluded that FTIR spectra combined with chemometrics techniques
could be used as a reliable method for the authentication analysis of milk products.
Effect of Transcranial Alternating Current Stimulation on Motor Performance
Authors: Miyaguchi Shota
Published: April 2024

Transcranial alternating current stimulation (tACS) is a non-invasive method of brain stimulation that can modulate oscillatory brain activity in the cortical region. By applying alternating current through two electrodes attached to a subject’s head, it is possible to entrain the oscillation of the cortex directly under one electrode to a specific frequency. This study finds that applying tACS to the primary motor cortex and cerebellar hemisphere improves motor performance. The study also shows the effect of tACS on the supplementary motor cortex to modulate the maintenance and update of motor plans in a bimanual motor task. These recent findings show that individualized tACS interventions can be tailored by selecting the stimulation area and frequency depending on the subject’s performance level and exercise task. By further investigating the effects of tACS on motor performance, it is believed that tACS can be applied in rehabilitation.
Conventional versus Peer Teaching in Flipped Classroom: Which is Better at Increasing Students’ Conceptual Understanding and Self-Efficacy?
Authors: Ramadoni Ramadoni
Published: April 2024

Calculus is one of the branches of mathematics which is often deemed difficult by students, indicated by students' weak conceptual understanding and low self-efficacy in calculus-related courses. Thus, innovative learning needs to be encouraged to overcome this problem. This study compares the effectiveness of whether a conventional or peer-teaching method is better at increasing students' conceptual understanding and self-efficacy in flipped classroom teaching practices. A descriptive quantitative method was used in this study. This research was conducted in two classes in the calculus course at a teacher education program at a university in West Sumatra. The first class was taught in a Conventional Flipped Classroom (CFC) with 34 students. The second class took place in a Peer Teaching Flipped Classroom (PTFC) with 36 students. Pre-test, post-test, self-efficacy questionnaires, and field notes were used for data collection. Data analysis techniques were performed using graphs. Results indicate that students' conceptual understanding and self-efficacy by peer teaching were better in the flipped classroom than in the conventional flipped classroom. Also, students’ academic background was found to be influential to students’ conceptual understanding and self-efficacy. We reveal that the student’s previous level of achievement in a peer-teaching flipped classroom influences their conceptual understanding and self-efficacy. This study suggests that future researchers and practitioners may implement peer-teaching flipped classrooms in advanced calculus. It is recommended that the group division should also consider the students’ prior achievement level.

Published: April 2024

Background

Following the 2022–2023 mpox outbreak, crucial knowledge gaps exist regarding orthopoxvirus-specific immunity in risk groups and its impact on future outbreaks.

Aim

We combined cross-sectional seroprevalence studies in two cities in the Netherlands with mathematical modelling to evaluate scenarios of future mpox outbreaks among men who have sex with men (MSM).

Methods

Serum samples were obtained from 1,065 MSM attending Centres for Sexual Health (CSH) in Rotterdam or Amsterdam following the peak of the Dutch mpox outbreak and the introduction of vaccination. For MSM visiting the Rotterdam CSH, sera were linked to epidemiological and vaccination data. An in-house developed ELISA was used to detect vaccinia virus (VACV)-specific IgG. These observations were combined with published data on serial interval and vaccine effectiveness to inform a stochastic transmission model that estimates the risk of future mpox outbreaks.

Results

The seroprevalence of VACV-specific antibodies was 45.4% and 47.1% in Rotterdam and Amsterdam, respectively. Transmission modelling showed that the impact of risk group vaccination on the original outbreak was likely small. However, assuming different scenarios, the number of mpox cases in a future outbreak would be markedly reduced because of vaccination. Simultaneously, the current level of immunity alone may not prevent future outbreaks. Maintaining a short time-to-diagnosis is a key component of any strategy to prevent new outbreaks.

Conclusion

Our findings indicate a reduced likelihood of large future mpox outbreaks among MSM in the Netherlands under current conditions, but emphasise the importance of maintaining population immunity, diagnostic capacities and disease awareness.

Published: April 2024

The article is devoted to the allocation of determinants and interaction tracing between the factors of axiological ordering of artistic and educational space in their interaction with mechanisms and factors of context environment. One of the ways to achieve the goal chosen is the selection of meaning-building factors that set the direction and motivation of artistic and educational activity and influence the specific functioning of the space, the study of which is conducted by theoretical reflection. It is concluded that the discourses of the artistic and educational space are designed to structure knowledge about key issues of contemporary culture and art, to model the theoretical base in accordance with different contexts or projects. It turned out that in different educational contexts, the regulation of the use of discourses analyzed in the article, paradigms and models are the standards of academic education, and the basis is the values associated with certain models of the world. Peculiarities of the axiological nature of the space under consideration are determined by the completeness of synthesis of values, fixed in traditions and different discourses

Published: April 2024

The piano is one of the most popular musical instruments among children. Playing the piano requires some effort from both children and teachers. At the same time, life puts forward new requirements for mastering advanced teaching methods that can provide maximum results. Piano teachers are faced with the task of making learning as meaningful, interesting, and personality-oriented as possible. With this in mind, the issues of finding, developing and implementing alternative forms and methods of organizing training, new advanced pedagogical ideas, as well as the latest educational technologies in the process of learning to play the piano are considered important. After all, technological progress does not stand still. Modern technologies are developing so actively that literally everyone has new products that seemed inaccessible yesterday. Therefore, the task of a modern teacher is to constantly monitor the emergence of new forms, methods of work, new technologies and effective means to maximize the stimulation of creative activity of students. Using the achievements of Advanced Science and technology significantly helps not only to activate students ' attention, but also to achieve significantly better learning outcomes. After all, modern children are the so – called "digital generation", brought up from childhood on free access to digital technologies of our time. This tendency to constantly technize our lives has both positive and negative aspects, but we cannot avoid it. Therefore, it is necessary to find the optimal balance in the use of modern technologies, the latest teaching methods and musical and game activities in the process of learning to play the piano. Modern innovations are designed to form the desire of piano students for independent learning, ideally-lifelong learning. They ensure the creation of a learning environment in which the child learns without compulsion, with great pleasure, guaranteed to learn the necessary amount of knowledge and provided that theory is constantly connected with practice.

Tədqiqatda onurğa əyrilikləri və onları təyin edən müasir cihazlar öyrənilmişdir. Yüksək səviyyəli qarşıdurma, həm də məharətlə müdafiə etmək bacarığı futbol oyununun xarakterik xüsusiyyətləridir. Futbol oyunçuların ustalığına müxtəlif tələblər qoyur. Bu, onların komandadakı funksiyalarının fərqliliyi və bu və ya digər oyunçunun oyunda həll etməli olduğu konkret tapşırıqlarla bağlıdır. Gənc futbolçuların böyük əksəriyyətində onurğa qüsurları vardır. Qüsurlardan asılı olaraq qamətin aşağıdakı müxtəlif formalarına rast gəlinir: Dairəvi kürək – başın, boyunun irəliyə əyriliyi, belin təbii əyriliyi artır. Döş qəfəsinin kifozunun artıqlığı diqqəti cəlb edir. Yastı əyilmiş kürək – sinə və belin təbii əyriliyi azdır. Onurğanın amortizasiya qabiliyyəti aşağıdır. Dairəvi əyilmiş kürək – belin təbii lordoz əyriliyi artıqdır, qarın irəliyə çıxmışdır. Yastı kürək – başqalarından onurğanın təbii əyriliyinin az olması və kürəyin yastı olması ilə fərqlənir.
Hər il idmanla bağlı çoxsaylı xəsarətlər fiziki fəaliyyətin azalmasına və iş qüvvəsinin itirilməsinə, həmçinin əlavə tibbi xərclərə səbəb olur. Dünya miqyasında idman zədələrinin dəyərinin ildə bir milyard dollar olduğu təxmin edilir. Təkcə Birləşmiş Millətlər Təşkilatında yarışma və istirahət idmanı ilə məşğul olan idmançılar arasında hər il 3-5 milyon yaralanmanın olduğu güman edilir. Bel ağrısı idmançıların dayaq-hərəkət sistemi problemləri arasında ən çox rast gəlinən şikayətlərdən biridir. İdmançıların yüksək fəaliyyət səviyyəsinə çatmaq səyləri təbii olaraq bel ağrısının inkişaf riskini artırır.

Son vaxtlar karate idman növü cəmiyyətdə böyük populyarlıq qazanmışdır. İdmanın bu növü üzrə beynəlxalq miqyaslı yarışlar artıq geniş vüsət almışdır. Bununla belə, təlim prosesinin psixoloji cəhətdən qurulması üçün metodoloji və metodoloji əsaslar hələ kifayət qədər inkişaf etdirilməmişdir. Bu baxımdan, hər bir idman növündə olduğu kimi karate idman növünün də hazırlıqları sırasına daxil olan psixoloji hazırlıq üzərində ciddi elmi işlərin görülməsi zərurət təşkil edir. İdmançıların məşqlərdə və həmçinin yarışqabağı, yarış zamanı və yarışdan sonra düşmüş olduqları psixoloji halları dərindən təhlil edilərək formalaşdırılması yarış uğurunun əldə edilməsində atılan müvəffəqiyyət addımlarının ön cərgəsində dayanır.

Qadın və kişinin cəmiyyətdəki rolu müxtəlif sahələrdə olduğu kimi iqtisadiyyata və xüsusən də iqtisadi inkişafa böyük təsir edir.Ancaq ənənəvi iqtisadi yanaşma perspektivlərinin kişiləri ön plana çəkdiyi və qadınların mövcud vəziyyətini izah etməkdə yetərli olmadığı müşahidə edilir. Ümumiyyətlə “Qadın və İqtisadiyyat” mövzusunda müxtəlif zamanlarda müəyyən işlər aparılmış olsa da, ”Feminist iqtisadiyyat”ının və ya “Gender iqtisadiyyat”ının tam olaraq ortaya çıxışı 1980-ci illərə təsadüf edir. Feminist iqtisadiyyat, iqtisadiyyatda qadının yerini sorğulamaq niyyətində deyil,ənənəvi iqtisadiyyatda qadın baxışınıda içində saxlayacaq yeni bir yanaşma yaratmaq məqsədindədir. Ancaq illər boyu qadınların iqtisadi və sosial həyatda məhdudlaşdırılması, yetərincə söz haqqı verilməməsi səbəbi ilə feminist iqtisad daha çox qadınların məruz  qaldığı bu rəftarın aradan qaldırılmasına yönəlmişdir. Bu baxımdan məqalədə  Azərbaycanda qadınların iqtisadiyyatda rolu araşdırılmış və bunun iqtisadiyyata təsiri qiymətləndirilmişdir.

Müasir dövrdə ibtidai siniflərdə şagirdlərin həm yazılı, həm də şifahi nitqini inkişaf etdirməkdə proqram (kurikulum) və dərsliklərə ciddi nəzarət edilir. Məhz ana dili üzrə hər bir dərsdə əsas yeri nitqin inkişafı tutur. Demək olar ki hər bir məşğələdə əsas dərs nitqin inkişafıdır. İbtidai sinif müəllimi dərsi elə təşkil etməlidir ki, şagird həm qramatik nəzəriyyəni, həm də orfoqrafik vərdişləri mənimsəsin. Eyni zamanda bununla yanaşı nitq prosesində sözləri düzgün tələffüz etməyi, onları düzgün və yerində seçməyi, cümlə qurmağı şagirdlər bacarmalıdırlar. Onlar oxuduqları, eşitdikləri və gördükləri şeylər haqqında danışmalı, özlərinin və başqalarının fikirlərini ifadə etməyi bacarmalıdırlar. Şagirdlər öz həyat təcrübələri haqqında danışarkən və yaxud yazarkən sözləri dəqiq və düzgün, öz yerində işlətməyi bacarmalıdırlar. Onlar eyni zamanda cümlələri qrammatik cəhətdən də düzgün qurmağı bilməlidirlər. Elə buna görə də, rabitəli nitqi inkişaf etdirmək üçün lüğət və cümlə üzərində iş aparılmalıdır. Bu proses rabitəli nitqi inkişaf etdirmək üçün əsas hazırlıq mərhələsidir.Əgər şagird fikrini izah edərkən sözləri düzgün və yerində işlətməzsə, bu zaman biz rabitəli nitqdən danışa bilmərik. Məqalədə bu məsələlər geniş şəkildə təhlil olunur.

İdmanın incəsənətlə inteqrasiyası ideyası yeni deyil, o, ilk dəfə qədim Yunanıstanda yaranmışdır. Bildiyiniz kimi, İstmiy, Panafiney, Pifiy, Nemey oyunlarında təkcə idmançılar deyil, həm də müğənnilər, musiqiçilər, natiqlər arasında yarışlar keçirilirdi.
Sonrakı illərdə bir çox elm adamları və ictimai xadimlər tərəfindən idmanla incəsənətin vəhdətinin möhkəmləndirilməsi ideyası səsləndirilib və dəstəklənmişdir. Hətta, müasir olimpiya hərəkatının banisi Kuberten bu ideyanın dərin tərəfdarı olmuşdur. O, öz əsərlərində idmanla incəsənətin bir-birini tamamlamaq və əlaqəni gücləndirmək zərurətini dəfələrlə qeyd etmişdir.
Son onilliklərdə idmanın incəsənətlə vəhdətinin möhkəmləndirilməsi istiqamətində çoxsaylı və əməlli addımlar atılmışdır.
Bu məqalənin məqsədi “Spartian oyunlarının” uzun illər təşkili və keçirilməsinin təcrübəsinə əsaslanaraq, onların məzmununu, xüsusiyyətlərini, habelə sosial-mədəni və pedaqoji əhəmiyyətini xarakterizə etməkdir.

Son illərdə baş verən lokal münaqişələrin və müharibələrin təhlili bizə göstərir ki, hava hücumundan müdafiə (HHM) sistemlərinin müasir PUA-lara qarşı döyüş tətbiqinin nəticələri bu sistemlərin müdafiə vasitələrindən tədricən “ov” obyektinə çevrilməsi qənaəti yaradır. Suriya, Liviya və İkinci Qarabağ müharibəsi təcrübəsi bizə göstərdi ki, PUA-lar qrup tərkibində eyni zamanda həm kəşfiyyat, həm də zərbə tapşırıqlarının icrası üçün istifadə edilir. Hərbi əməliyyatların forma və metodlarının inkişaf göstəricilərinin təhlili bizə göstərir ki, yaxın gələcəkdə PUA-lar HHM vasitələrinin susdurulması və zərərsizləşdirilməsi, koordinatları əvvəlcədən məlum olan və yüksək səviyyədə müdafiə edilən düşmən hədəflərinin məhv edilməsi, həmçinin kəşfiyyat zamanı müəyyən olunmuş obyektlərə raket və bomba zərbələrinin endirilməsinin əsas hissəsini öz üzərinə götürəcək.
