Assessing the Validity of the 12th Grade Ministerial Exam of English Language in Kurdistan
Authors: Mustafa Awat , Azeez Nadhim , Ahmad Rawand
Published: March 2022

It has been almost a decade that the format of 12th grade ministerial exam questions has been changed to Multiple Choice Questions (MCQ). It has been claimed that language tests have to reflect what learners study in the class during the process of learning. It is the aim of this study to investigate the validity of the 12th ministerial exanimation in the light of the communicative language approach (CLA). For this purpose, the researchers designed a questionnaire for 100 freshly graduates of the 12th grade learners from Kurdistan Region schools. The overall results show that the test doesn’t follow the CLA testing principles. In addition, more than %85 of the learners reported that they had learned little English during their study year, and they mostly study on their teachers’ pamphlets rather than the course book. Nevertheless, the 12th grade learners are generally satisfied with the format of the ministerial examination of English and think that question items are easy to answer.

The article analyzes various ways to ensure the geometric parameters of forgings in the processes of hot volumetric stamping. The fact of high efficiency of coordinate measurements of geometric parameters of forgings has been established to ensure the identification of negative production factors affecting the geometric accuracy of forgings manufacturing. The designs of common control devices and measurement schemes of geometric parameters of the crankshaft forging do not allow performing coordinate measurements of the crankshaft forging in shop conditions. The coordinate scheme, the design of the control device and the method of determining the size of the parameters of the allowance distribution along the root and connecting rod necks of the crankshaft are considered. On the basis of the methodology given in the article for determining the parameters of the allowance distribution, a technique for controlling the geometric accuracy of hot volumetric stamping has been developed, the accuracy of controlling the output parameters of the geometric accuracy of forgings of crankshafts of heavy-duty vehicles has been improved.

В настоящей работе рассматривается возможность применения сейсмоизолирующих опор в системах сейсмозащиты шаровых резервуаров, предназначенных для хранения сжиженных углеводородных газов, в сейсмически неустойчивых условиях эксплуатации. Основное внимание уделено исследованию опорных конструкций, в состав которых введены резинометаллические виброизоляторы. На основе положений теории длительной прочности рассмотрены вопросы работоспособности резинометаллических сейсмоизолирующих опор (РМСО). Применение РМСО позволяет снизить сейсмические нагрузки в опорных стойках резервуара в 1,5-2,0 раза. При этом анализ напряженно-деформированного состояния (НДС) корпуса резервуара показал, что элементы конструкции сооружения сохраняют эксплуатационные характеристики при сейсмическом воздействии и отвечают условиям прочности в соответствии с требованиями действующей нормативно-технической документации.

Authors: GÜL Merve , ÇİFTÇİ İhsan
Published: March 2022

Onikomikoz, tırnak hastalıklarının yaklaşık %50'sini oluşturan başlıca tırnak enfeksiyonlarından biridir. Hastaların tedavi uyumsuzluğu, yüksek maliyet, uzun tedavi süreleri ve hastalığın tekrarlama olasılığının yüksek olması gibi pek çok faktör onikomikoz tedavisinde zorluk yaratır. Doğru ve uygun maliyetli onikomikoz tedavisi için tanıyı doğru koymak da önemlidir. Farklı tanı yöntemleri kullanılsa da, en sık tercih edilen yöntem fungal kültürdür. Onikomikozun tedavisinde oral ve topikal tedavi yöntemleri ayrı ayrı veya kombine olarak uygulanabilir. Oral tedavide allilaminler ve azoller kullanılmakta olup, etkinlik yüksektir. Ancak hepatotoksik etki ve ilaç-ilaç etkileşimleri oral tedavi için büyük problemler yaratabilir. Topikal tedavide ise en sık siklopiroks, amorolfin, efinaconazole ve tavaborole kullanılır. Topikal tedavi yöntemi olarak farklı antifungaller çözeltiler veya bitkisel ekstratlar da kullanılmaktadır. Topikal ilaçların uygulanması daha kolaydır ve çok daha az yan etki gösterir, ancak tırnakların keratin açısından zengin yapısı yetersiz penetrasyona neden olur. Bu derlemede, onikomikoz, tanı yöntemleri ve tedavideki yeni yaklaşımların neler olduğu gözden geçirilmiştir.

Neue Synthese für Tellurocarbonyl-difluorid
Authors: Haas Alois , Limberg Christian
Published: March 2022

Reaction between CF3TeTeCF3 and (CH3)3SnH in Et2O provides (CH3)3SnTeCF3 in 75% yield. This is a good starting material for the preparation of TeCF2 and its cyclic dimer, because pyrolysis of (CH3)3SnTeCF3 at 280° (10-3 Torr) yields TeCF2 in 60% yield. On warming from -196° to 20°, TeCF2 dimerizes quantitatively to the corresponding tetrafluoro-l,3-ditelluretane.

Water content of individual leaves or vegetation canopies is a significant variable in plant physiological processes. The water content of the vegetation leaves plays a very significant role. The ability of hyperspectral advanced technology to accurately evaluate leaf and canopy water content has improved large-scale measures. Due to the presence of water absorption band in near and SWIR wavelength range, electromagnetic spectrum will allow us to correctly measure the leaf water content. Three different parameters were used to describe the water status: Equivalent Water Thickness (EWT), Gravimetric Water Content (GWC), and Plant Water Concentration (PWC), with leaf multi angular reflectance spectrum, to find sensitive spectral indices, to correctly assess water content of leaves in a wide range of plant species. Using spectral indices derived from multi angular reflectance spectra, we looked into the possibility for predicting leaf water content of six species in the study area. To analyze the status of leaf water, three different forms of hyperspectral indices were evaluated, including the Simple Ratio (SR), Normalized ratio wavelength (ND) and Double Difference ratio (DDn). To look over the possibility of predicting the leaf water status of the species in the study field, we proposed four new indices. The results showed that EWT is comparatively more sensitive to trace leaf water status than GWC and PWC. The best-established EWT indices were (R905-R1795)/(R1905-R1935), R1350/R1390, (R840-R1565)/(R840+R1565) and (R925-R1625)/ (R925+R1625) and the performance of the proposed hyper-spectral indices surpassed the performance of other indices in this study. The mentioned indices were then further analyzed on LOPEX and ANGERS databases for validation of our suggested indices and we come up with better results. This study indicates that spectral indices can be used and could be more reliable to predict leaf water content, but future studies will need to include more plant species and field data. The newly developed indices can be used to estimate EWT using simple laboratory measurements, making them helpful for agricultural environmental sciences and ecology related studies.

Acute severe pain is the most common condition for emergency consultations. Opioids are the cornerstone of the treatment. However, they expose to various adverse effects. We describe a case of a 22-year-old woman with severe pain to her right hand, after a domestic fall, successfully managed by nebulized ketamine. Ketamine administration via nebulized route might be an attractive and non invasive alternative to opioids use in acute pain management.

The use of hydrogen as an energy vector has been considered as one promising way to attend society decarbonization. Hydrogen can be used as a chemical to store electricity and as a fuel to electric fuel cell mobility. This work makes hydrogen production potential economical evaluation of 5 real solar photovoltaic installations intended primarily for self-consumption. The surplus electrical energy can be used to produce hydrogen, which will be used later as a form of energy, potentially in an application. That provides greater economic value. Hydrogen serves as an important career to the storage of energy and can be more interesting and competitive than a battery-based solution. The results show that the use of hydrogen is only economically viable for mediumsized installations, greater than 300MW and for the production of hydrogen for mobility.

Stevens Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) are hypersensitivity reaction, mainly to drugs, characterized by skin detachment. They are dermatological emergencies, and bacteremia is the main cause death, especially in patients with extensive cutaneous involvement. We reviewed and summarized the large retrospective studies that focused on the risk factors and main pathogens involved in patients with SJS and TEN who developed bacteremia. Our results showed that the risk factors include a Total Body Surface Area (TBSA) higher than 10%, higher Severity-of-Illness Score For Toxic Epidermal Necrolysis (SCORTEN), hypertension, previous opiate use, White Blood Cells (WBC) > 10000/mL; C-Reactive Protein (CRP) > 100mg/mL; procalcitonin (PCT) ≥ 1μg/L; and skin colonization with P. aeruginosa, S. aureus, and methicillin-resistant S. aureus (MRSA). The most frequently isolated pathogens from blood cultures were S. aureus, E. faecalis, P. aeruginosa, Enterobacter spp, and A. baumannii. The identification and consideration of these variables on each patient with SJS and TEN could result in an earlier diagnosis, proper management and even prevention of bacteremia in this population.
The chemistry of Cu3N and Cu3PdN nanocrystals

Published: March 2022

Cu3N and Cu3PdN nanocrystals are attractive materials with numerous applications ranging from optoelectronics to catalysis. However, their chemical formation mechanism and surface chemistry are unknown or contested. In this work, we first optimize the synthesis and purification to yield phase pure, colloidal stable Cu3N and Cu3PdN nanocubes. Second, we elucidate the precursor conversion mechanism that leads to the formation of Cu3N from copper(II) nitrate and oleylamine. We find that oleylamine is both the reductant and nitrogen source. Oleylamine is oxidized to a primary aldimine and the latter reacts further with oleylamine to a secondary aldimine, eliminating ammonia. Ammonia reacts with Cu(I) to form Cu3N. Third, we investigated the surface chemistry of the nanocrystals using solution NMR spectroscopy and X-ray photoelectron spectroscopy (XPS). We find a mixed ligand shell of aliphatic amines and carboxylates. The carboxylate is produced in situ during the synthesis. While the carboxylates appear tightly bound, the amines are easily desorbed from the surface. Finally, we analyze the optoelectronic properties by UV-Vis and XPS. Doping with palladium decreases the bandgap but the material remains a semiconductor. These results bring insight into the chemistry of metal nitrides and will help the development of other metal nitride nanocrystals.
All Reasons are Fundamentally for Attitudes
Authors: Way Jonathan , McHugh Conor
Published: March 2022

As rational agents, we are governed by reasons. The fact that there’s beer at the pub might be a reason to go there and a reason to believe you’ll enjoy it. As this example illustrates, there are reasons for both action and for belief. There are also many other responses for which there seem to be reasons – for example, desire, regret, admiration, and blame. This diversity raises questions about how reasons for different responses relate to each other. Might certain such reasons be more fundamental than others? Should certain reasons and not others be treated as paradigmatic? At least implicitly, many philosophers treat reasons for action as the fundamental or paradigmatic case. In contrast, this paper articulates and defends an alternative approach, on which reasons for attitudes are fundamental, and reasons for action are both derivative and, in certain ways, idiosyncratic. After outlining this approach, we focus on defending its most contentious thesis, that reasons for action are fundamentally reasons for intention. We offer two arguments for this thesis, which turn on central roles of reasons: that reasons can be responded to, and that reasons can feature as premises of good reasoning.  We then examine objections to the thesis and argue that none succeed. We conclude by sketching some ways in which our approach is significant for theorising about reasons.
Practical Commitment in Normative Discourse
Authors: Vayrynen Pekka
Published: March 2022

Many normative judgments play a practical role in our thought. This paper concerns how their practical role is reflected in language. It is natural to wonder whether the phenomenon is semantic or pragmatic. The standard assumption in moral philosophy is that at least terms which can be used to express “thin” normative concepts – such as good, right, and ought – are associated with certain practical roles somehow as a matter of meaning. But this view is rarely given explicit defense or even articulation. I’ll consider several versions of the view, and argue that even the most promising among them are problematic. Terms like ought are often used in ways where their customary practical role is absent. Such cases give us a choice: either offer some plausible explanation of why the relevant practical upshots don’t show up in these cases despite featuring in our semantic theory for these expressions, or else don’t build them into that theory. I argue that plausible explanations of the requisite sort aren’t forthcoming in either descriptive semantics or metasemantics for normative language. In closing I briefly consider the prospects for a pragmatic account of the phenomenon and some broader ramifications for metaethics and the philosophy of normativity.

Published: March 2022

Background: Coronavirus disease 2019 (COVID-19) is a worldwide public health emergency. Aims: This study aimed to investigate the epidemiological and clinical characteristics of patients with COVID-19 in Saveh city, Islamic Republic of Iran in 2020. Methods: In this descriptive analytical research, 3181 patients suspected of having COVID-19 who visited Saveh medical centres were investigated. Patients were confirmed with COVID-19 using polymerase chain reaction testing. Data on sociodemographic, epidemiological and clinical characteristics of the patients were collected using a validated form through interviews and medical records. The chi-squared, t and Fisher exact tests were used to assess differences in sociodemographic, epidemiological and clinical characteristics between patients with positive and negative polymerase chain reaction results. Logistic regression analysis was used to examine the association between independent variables and death from COVID-19. Results: About half the patients (48.3%) had a history of chronic disease. Diabetes (16.2%), high blood pressure (14.8%) and cardiovascular disease (12.4%) were the most prevalent chronic diseases among patients who were confirmed positive for COVID-19. Risk factors for death among confirmed COVID-19 patients were: intubation (odds ratio (OR) = 8.97; 95% confidence interval (CI): 5.15–15.63), age ≥ 80 years (OR = 5.81; 95% CI: 1.91–17.60), oxygen saturation < 93% (OR = 2.48; 95% CI: 1.51–4.08), diabetes (OR = 1.88; 95% CI: 1.00–3.54) and shortness of breath (OR = 1.70; 95% CI: 1.02–2.82). Conclusion: Given the greater risks of contracting and dying from COVID-19 in certain groups of patients, health education programmes targeting these groups are recommended.
Unwitting Adult Marijuana Poisoning: A Case Series
Authors: Hsueh Andy , Fong Kelly , Kendrics Kayla , Saddiqi Nadia , Phan Tammy , Reibling Ellen , Wolk Brian
Published: March 2022

Study purpose: With increasing state legalization, marijuana use has become commonplace throughout much of the United States. This has resulted in expected and potentially dangerous consequences. Existing literature on unintentional exposure focuses primarily on the pediatric population. Despite mounting cases of unintentional exposure to marijuana, minimal research has been published on the effects of non-consensual marijuana consumption in adults. Here, we report on a cluster of adults with unwitting marijuana exposure. Methods: A cluster of patients who presented to the Emergency Department (ED) within one hour of ingesting marijuana-contaminated food at a wedding reception event were subsequently referred to the Medical Toxicology Service. We conducted a retrospective analysis of twelve subject charts who were exposed to the marijuana-contaminated food and a qualitative analysis of six of the 12 subjects’ experiences who willingly consented to be interviewed. The interviews were then analyzed and coded to categorize common themes within the subjects’ experiences. Themes categorically selected throughout the interview analysis included “Thoughts & Feelings” and “Effect on Work.” The study was approved by the Institutional Review Board. Results: Three of the subjects (25%) required prolonged observation due to persistent symptoms of acute marijuana intoxication. Eleven (92%) were urine immunoassay positive for tetrahydrocannabinol (THC). Two subjects (17%) tested positive for ethanol in their blood. None of the subjects reported a prior history of marijuana use. Common symptoms experienced by the subjects included confusion (50%), difficulty speaking (67%), nausea (25%), tremors (17%), and feelings of unreality (33%). All interviewed subjects reported sleepiness and three (50%) reported a negative impact on work. Subjects also reported multiple emotions, including anger, confusion, disbelief, and helplessness. None of the cases resulted in admission to the intensive care unit or death. Conclusions: Our case series illuminates the effects of unwitting and/or unintentional marijuana exposure in adults, with sufficient systemic effects resulting in individuals seeking emergency care. Legal and ethical barriers have limited the study of marijuana outside of controlled conditions. While the exposure in this study did not result in admission to the ICU or death, it did result in psychological distress and reported symptoms lasting weeks after the incident. As marijuana becomes readily available, the potential as an unwitting or even malicious intoxicant may increase.

Purpose: Cannabis Use Disorders are associated with a quadrupling of the risk of developing depression, and the use of cannabis to alleviate depressive symptoms is increasingly widespread. Despite high rates of cannabis use among individuals with affective disorders, those who suffer from depression do not frequently access traditional treatment. Our prior work has demonstrated that a technology- and social media-assisted intervention combining cognitive behavioral therapy (CBT), motivational enhancement therapy (MET), and social media support via Facebook showed promise in changing cannabis use and mood symptoms among depressed individuals with cannabis use disorder (CUD). The current project examined alcohol co-use and anxiety in this population, effectiveness of this approach in changing drinking behaviors and anxiety, and perceived helpfulness of the intervention. Methods: In a 10-week pilot intervention study, adults (N=20) with CUD and Major Depressive Disorder (MDD) received an intervention combining computer-assisted CBT/MET targeting depression and cannabis use with peer and therapist support via Facebook, Connected Cannabis Users’ Network for Enhancement of Cognitive Therapy (CONNECT). Self-reported past 30 day alcohol and cannabis use was assessed using a calendar-assisted timeline follow back interview at baseline and treatment-end. Anxiety was measured using the GAD-7. Perceived helpfulness of the intervention was evaluated qualitatively in individual participant interviews. Results: From baseline to treatment-end, CONNECT participants reduced the frequency of both cannabis use (M=24 vs. 8.9 days, p<0.05) and heavy alcohol use (M=1.7 vs. 0.4 days, p<0.05). Anxiety also declined over the course of treatment (M=5.4 vs. 3.2, p<0.05). More than half (57%) of CONNECT participants reported the social media intervention was helpful for their mood as well as cannabis use, and 72% indicated that they would recommend it to a friend. Qualitative data indicate that CONNECT was most helpful in 3 core areas: (1) social support/not feeling alone with their problems, (2) CBT skills training, (3) bolstering motivation to change substance use. Conclusion: Combining technology-assisted and social media interventions may be an effective strategy for populations struggling with concurrent depression and CUD. Beyond primary outcome variables (i.e., depression and cannabis use), participants also reported reductions in heavy alcohol use and anxiety, indicating that this intervention may effectively produce transdiagnostic process changes. In light of the growing demand for telemedicine and digital health interventions in the wake of COVID-19, further research and potential dissemination of this approach appears warranted.
Exploring Social Support as a Moderator between Adverse Childhood Experiences and Cannabis Use
Authors: Hubbard Sterling , King Shelby , Elder Sarah , Woodward Matthew , Teeters Jenni
Published: March 2022

Background: Research shows that unresolved childhood trauma can lead to an abundance of health disparities and increase the risk for problematic substance use in adulthood, particularly problematic cannabis use. Individuals who have experienced four or more adverse childhood experiences (ACEs) double their risk of problematic substance use, but research has shown that protective factors, such as social support, can buffer against this cumulative risk. Although past research has found that social support can buffer against problematic alcohol use, there is a need to understand how social support relates to ACEs and problematic cannabis use. The present study aims to identify if perceived social support moderates the association between ACEs and cannabis use. In addition to overall perceived social support, various domains of perceived social support (friends, family, and significant other support) were examined to determine whether these domains differentially impacted the association between ACEs and cannabis use. Methods: Data were collected using a university online subject pool (n = 382) from a college student sample from a mid-southern university (75% Caucasian, 78% female). The participants completed a battery of measures assessing perceived social support (i.e., the Multidimensional Scale of Perceived Social Support; MSPSS), childhood trauma (i.e., the Adverse Childhood Experiences Scale; ACEs), and the number of days of cannabis use in the past month (i.e., the Drug Use Questionnaire). Results: Moderation analyses were used to analyze if overall perceived social support and the various domains of MSPSS (family, friend, and significant other) moderated the relation between ACES and cannabis use. Findings revealed that perceived support from a significant other significantly moderated the association between ACEs and cannabis use (b = .17, p = .04) such that the relation between ACEs and cannabis use was stronger when there was higher perceived support from a significant other. Overall social support and support from friends and family members did not moderate this association. Discussion: Overall, these findings contradict the previous literature in that more support from a significant other did not buffer the association between ACEs and cannabis use. Rather, the relation between ACEs and cannabis use was strongest at higher levels of significant other support. This suggests that perceived social support may play a unique role alternative to buffering the relationship between ACEs and cannabis use. Future work is needed to examine factors such as level of cannabis use within a trauma survivor’s social network or significant other accommodation of symptoms, which may enhance perceptions of support but also encourage cannabis use.

Authors:   University of Florence (Università degli studi di Firenze), Gabovich Valeriya M.
Published: March 2022

Architectural structures are often found in both in the monumen- tal and in the easel painting of Siena in the 15th century, but it is in the predella polyptychs that they enter into dialogue with human figures, creating harmo- nious compositions or original contrasts. In some works, they serve as a deco- rative background for narrative scenes, while in others they become integral parts of them. This article demonstrates that, despite the strong attachment of the Sienese artists of the Quattrocento era to the medieval tradition, it is in the predella polyptychs of the 15th century that innovations in the field of depicting architectural structures are adopted. Through the examination of a number of scenes from the predella of the sienese polyptychs, it became obvious that it was in the architectura picta that artists had greater freedom and depicted architec- tural innovations that had not yet been reflected in actual Sienese architecture. There are many predella fragments depicting architectural structures, but they have not been fully documented. The brief excursion reported in this study aims to review the most representative samples, organize them chronologically and analyze their evolution through almost the entire 15th century.
THE MURANO DIPTYCH. AN EARLY BYZANTINE IVORY BOOK COVER
Authors:   nstitute of Philosophy and Law of the Siberian Branch of the Russian Academy of Sciences, Lidova Maria A.
Published: March 2022

The paper is dedicated to the ivory cover, commonly referred to in scholarship as the Murano diptych. The name, alluding to one of the Vene- tian islands, derives from an 18 th -century historic record attesting the presence of one of the sides of the cover in a Murano monastery. This part of the diptych was later brought to Ravenna and today is on display at the Ravenna National Museum. The fragments of the other side of the diptych are dispersed among various museum and library collections in Manchester, Paris, Berlin, and Saint Petersburg. Notwithstanding the scattered location of the ivory, it is possible to reconstruct its constituent elements and original decoration. Besides offering a detailed analysis of the surviving fragments, this paper focuses on the overall iconographic program and formal characteristics of the diptych, and studies its reliefs in light of late antique ivory carving and church decoration. It is argued that late antique ivories represent an important source of information concerning the use of apocryphal imagery in monumental art, enabling us to reconstruct the imagery of early Byzantine narrative cycles.

Definite integral of a hyperbolic quotient function expressed in terms of the Lerch function
Authors: Reynolds Robert , Stauffer Allan
Published: March 2022

In applied sciences it is always useful to improve the catalogue of definite integrals available in tables. In this paper the authors derived definite integrals used in research concerned with perturbation analysis of single Langmuir solitons, proving the Riemann Hypothesis and the Goldbach conjecture and the LPM effect in sequential bremsstrahlung. We also derived new results and summarized these formulae in a table of integrals.

On Restrained Strong Resolving Domination in Graphs
Authors: Sumaoy Helyn Cosinas , Rara Helen M.
Published: March 2022

A set S âŠ† V (G) is a restrained strong resolving dominating set in G if S is a strongresolving dominating set in G and S = V (G) or âŸ¨V (G) \ SâŸ© has no isolated vertex. The restrained strong resolving domination number of G, denoted by Î³rsR(G), is the smallest cardinality of a restrained strong resolving dominating set in G. In this paper, we present characterizations of the restrained strong resolving dominating sets in the join, corona and lexicographic product of two graphs and determine the exact value of the restrained strong resolving domination number of each of these graphs.

Published: March 2022

Multivariate modeling of dependence and its impact on risk assessment remains a major concern for financial institutions. Thus, the copula model, in particular Archimedean hierarchical copulas (HAC) appears as a promising alternative, capable to precisely capture the structure of dependence between financial variables. This study aims to widen the sphere of practical applicability of the HAC model combined with the ARMA-APARCH volatility forecast model and the extreme values theory (EVT). A sequential process of modeling of the VaR of a portfolio based on the ARMA-APARCH-EVT-HAC model is discussed. The empirical analysis conducted with data from international stock market indices clearly illustrates the performance and accuracy of modeling based on HACs.

Published: March 2022

In this paper, we introduce AC* and ACG*-type properties and then, using theseconditions along with other concepts, define two Denjoy-type integrals of a function with values in a locally convex topological vector space (LCTVS). We show, among others, that these newly defined integrals are included in the SH integral, a stronger version of the Henstock integral for LCTVS-valued functions.

Application of a Heuristic Method to Solve Nonlinear Oscillators with Irrational Forces
Authors: GonzÃ¡lez-Gaxiola Oswaldo , Ruiz de ChÃ¡vez Juan
Published: March 2022

This paper applies another amplitude-frequency relationship as of late established by Yazdi and Tehrani (Alexandria Engineering Journal 54 99-103, 2015) to analyze periodical solutions of nonlinear oscillators; such oscillators are considered emphatically nonlinear on the grounds that they contain an irrational force term. Estimation strategy is straightforward yet additionally helpful and its formulation depends on combining the energy balance technique with an uncommon collocation point. At long last, we uncover the convenience and proficiency of the proposed technique resolving three instances of conservativeÂ  nonlinear oscillators in which the maximum relative error acquired is $2.5\%.$ Exposed models show that the strategy has a high precision to solve mechanical issues of both small and huge estimations of the oscillation amplitude. Finally, the methodology used can be very useful for the study of nonlinear oscillators in basic undergraduate physics and mechanics courses.
