Comparison of Early Postoperative Diaphragm Muscle Function after Lobectomy via VATS and Open Thoracotomy: A Sonographic Study
Authors: Kocjan Janusz , Rydel Mateusz , Czyżewski Damian , Adamek Mariusz
Published: April 2024

Although a growing body of evidence emphasizes the superiority of VATS over conventional thoracotomy, little is still known about early postoperative diaphragm muscle function after lobectomy via these two approaches. To fill the gap in existing literature, we conducted a comparative study between VATS and conventional thoracotomy in terms of postoperative diaphragm muscle function, assessing its contractility, strength, the magnitude of effort and potential risk of dysfunction such as atrophy and paralysis. A total of 59 patients (30 after VATS), who underwent anatomical pulmonary resection at our institution, were enrolled in this study. The control group consisted of 28 health subjects without medical conditions that could contribute to diaphragm dysfunction. Diaphragm muscle was assessed before and after surgery using ultrasonography. We found that both surgical approaches were associated with postoperative impairment of diaphragm muscle function—compared to baseline data. Postoperative reduction in diaphragm contraction was demonstrated in most of the 59 patients. In the case of the control group, the differences between measurements were not observed. We noted that lobectomy via thoracotomy was linked with a greater percentage of patients with diaphragm paralysis and/or atrophy than VATS. Similar findings were observed in referring to diaphragm magnitude effort, as well as diaphragm contraction strength, where minimally invasive surgery was associated with better diaphragm function parameters—in comparison to thoracotomy. Disturbance of diaphragm work was reported both at the operated and non-operated side. Upper-right and left lobectomy were connected with greater diaphragm function impairment than other segments. In conclusion, the VATS technique seems to be less invasive than conventional thoracotomy providing a better postoperative function of the main respiratory muscle.

Published: April 2024

The results of a photothermal spectroscopy technique that effectively images convective and conductive heat flow in liquids via a thermal lensing effect are described. Pure water; sodium chloride solutions at salinities of approximately 5, 15, 25, and 35 g/kg; and an artificial seawater of 35 g/kg were studied across a range of temperatures. This system was studied because of the importance of thermal pluming in seawater. ‘Frustrated’ thermal starting plumes were observed near the temperature of maximum density. The physical characteristics of these thermal starting plumes are reported.
Temperature-Driven Structural Evolution during Preparation of MCM−41 Mesoporous Silica
Authors: Xu Tao , Cui Kuixin , Jin Shengming
Published: April 2024

This study explores the influence of micelles on the evolution of MCM−41’s pore structure via 24 h hydrothermal treatments in a range of temperatures from 100 °C to 200 °C. MCM−41 was characterized using BET, SAXD, FTIR, TEM, and TG-DSC. The findings demonstrate that with temperature elevation from 100 °C to 160 °C, the micelles undergo expansion, leading to an enhanced lattice constant from 4.50 nm to 4.96 nm and an increase in pore diameter from 3.17 nm to 3.45 nm, while maintaining the structural orderliness of the pore channels. Upon cooling, the reversible contraction of micelles and the strategic addition of water glass contribute to a reduction in pore size. However, at a threshold of 180 °C, the SAXD (100) peak’s half-peak width surges by approximately 40% relative to that at 160 °C, illustrating a progressive disruption of the hexagonal configuration of MCM−41. Coupled with elevated silica dissolution at higher temperatures in an alkaline solution, a total disintegration of the ordered pore structure at 200 °C results in a drastic reduction in the specific surface area to 307 m2/g. These results are beneficial to developing structural transformation mechanisms of MCM−41 materials and designing mesoporous materials via temperature modulation innovatively.

Authors: Drungilas Paulius , Jankauskas Jonas , Junevičius Grintas
Published: April 2024

Let n>m be positive integers. Polynomials of the form zn±zm±1 are called Borwein trinomials. Using an old result of Bohl, we derive explicit formulas for the number of roots of a Borwein trinomial inside the unit circle |z|<1. Based on this, we determine all Borwein trinomials that have a complex Pisot number as a root. There are exactly 29 such trinomials.

Authors: Kitcharanant Nitchanant , Atthakomol Pichitchai , Khorana Jiraporn , Phinyo Phichayut , Unnanuntana Aasis
Published: April 2024

Background and Objectives: Achieving prefracture functional status is a critical objective following a hip fracture, yet fewer than half of patients reach this milestone. The adoption of tools for assessing functional outcomes is increasingly recognized as essential for evaluating recovery following treatment for fragility hip fractures. We developed multivariable clinical prediction criteria to estimate the likelihood of patients regaining their prefracture activities-of-daily-living (ADL) status one year after sustaining a fragility hip fracture. Materials and Methods: A retrospective cohort of patients treated for fragility hip fractures at a university-affiliated tertiary care center between February 2017 and April 2019 served as the basis for developing and internally validating the clinical prediction criteria. We applied a multivariable fractional polynomial method to integrate several continuous predictors into a binary logistic regression model. Results: The study included 421 patients, 324 (77%) of whom reported regaining their prefracture activities-of-daily-living level one year after experiencing fragility hip fractures. Significant predictors, such as the prefracture Barthel index, EQ-VAS score, and treatment modality, were incorporated into the predictive model. The model demonstrated excellent discriminative power (AuROC of 0.86 [95% CI 0.82–0.91]) and satisfactory calibration. Conclusions: The predictive model has significant discriminative ability with good calibration and provides clinicians with a means to forecast the recovery trajectories of individual patients one year after a fragility hip fracture, which could be useful because prompt clinical decision-making is aided by this information. Patients and caregivers can also be counseled and encouraged to follow up with the medical activities and interventions deemed essential by doctors who used the prediction tool. Access to the model is provided through a web application. External validation is warranted in order to prove its applicability and generalizability.
Prednisolone Nanoprecipitation with Dean Instability Microfluidics Mixer
Authors: Wong Yu , Yang Siyu , Wen Weijia
Published: April 2024

Dean flow and Dean instability play an important role in inertial microfluidics, with a wide application in mixing and sorting. However, most studies are limited to Dean flow in the microscale. This work first reports the application of Dean instability on organic nanoparticles synthesis at De up to 198. The channel geometry (the tortuous channel) is optimized by simulation, in which the mixing efficiency is considered. With the optimized design, prednisolone nanoparticles are synthesized, and the size of the most abundant prednisolone nanoparticles is down to 100 nm with an increase in the Re and De and smallest size down to 46 nm. This work serves as an ice-breaker to the real application of Dean instability by demonstrating its ability in mixing and nanomaterials like nanoparticle synthesis.
Precisely Printable Silk Fibroin/Carboxymethyl Cellulose/Alginate Bioink for 3D Printing

Published: April 2024

Three-dimensional (3D) bioprinting opens up many possibilities for tissue engineering, thanks to its ability to create a three-dimensional environment for cells like an extracellular matrix. However, the use of natural polymers such as silk fibroin in 3D bioprinting faces obstacles such as having a limited printability due to the low viscosity of such solutions. This study addresses these gaps by developing highly viscous, stable, and biocompatible silk fibroin-based inks. The addition of 2% carboxymethyl cellulose sodium and 1% sodium alginate to an aqueous solution containing 2.5 to 5% silk fibroin significantly improves the printability, stability, and mechanical properties of the printed scaffolds. It has been demonstrated that the more silk fibroin there is in bioinks, the higher their printability. To stabilize silk fibroin scaffolds in an aqueous environment, the printed structures must be treated with methanol or ethanol, ensuring the transition from the silk fibroin’s amorphous phase to beta sheets. The developed bioinks that are based on silk fibroin, alginate, and carboxymethyl cellulose demonstrate an ease of printing and a high printing quality, and have a sufficiently good biocompatibility with respect to mesenchymal stromal cells. The printed scaffolds have satisfactory mechanical characteristics. The resulting 3D-printing bioink composition can be used to create tissue-like structures.

Published: April 2024

The charge properties and regularities of mutual influence of the electro-physical parameters in a metal (M)/insulator (I)/two-dimensional crystal heterostructure were studied. In one case, the transition metal dichalcogenide (TMD) MoS2 was considered as a two-dimensional crystal, and in another the Weyl semi-metal (WSM) ZrTe5, representative of a quasi-two-dimensional crystal was chosen for this purpose. By self-consistently solving the electrostatic equations of the heterostructures under consideration and the Fermi–Dirac distribution, the relationship between such parameters as the concentration of charge carriers, chemical potential, and quantum capacitance of the TMD (WSM), as well as the capacitance of the I layer and the interface capacitance I–TMD (WSM), and their dependence on the field electrode potential, have been derived. The conditions for the emergence of charge instability and the critical phenomena caused by it are also determined.
Cotton–Cork Blended Fabric: An Innovative and Sustainable Apparel Textile for the Fashion Industry
Authors: Arya Preeti , Sarkar Ajoy K.
Published: April 2024

Cotton is a preferred textile fiber for apparel textiles and is used primarily for summer wear. However, cotton has drawbacks, such as poor wrinkle resistance, and therefore, blends of cotton with other fibers have gained acceptance in the industry. In this study, a novel 90:10 cotton–cork blended fabric was studied for its physical and performance properties and benchmarked against a 100% cotton fabric. Fabric samples were analyzed to determine the wrinkle recovery angle, tenacity, abrasion resistance, shrinkage, CLO value, moisture absorption, and dyeability. The samples were further analyzed using SEM, DSC, and FTIR. The results showed significant differences between the two fabrics. Cotton–cork blended textile fabric had higher performance properties with the potential to be a viable, sustainable apparel textile.
Transcutaneous Ablation of Lung Tissue in a Porcine Model Using Magnetic-Resonance-Guided Focused Ultrasound (MRgFUS)
Authors: Yang Jack B. , Powlovich Lauren , Moore David , Martin Linda , Miller Braden , Nehrbas Jill , Tewari Anant R. , Mata Jaime
Published: April 2024

Focused ultrasound (FUS) is a minimally invasive treatment that utilizes high-energy ultrasound waves to thermally ablate tissue. Magnetic resonance imaging (MRI) guidance may be combined with FUS (MRgFUS) to increase its accuracy and has been proposed for lung tumor ablation/debulking. However, the lungs are predominantly filled with air, which attenuates the strength of the FUS beam. This investigation aimed to test the feasibility of a new approach using an intentional lung collapse to reduce the amount of air inside the lung and a controlled hydrothorax to create an acoustic window for transcutaneous MRgFUS lung ablation. Eleven pigs had one lung mechanically ventilated while the other lung underwent a controlled collapse and subsequent hydrothorax of that hemisphere. The MRgFUS lung ablations were then conducted via the intercostal space. All the animals recovered well and remained healthy in the week following the FUS treatment. The location and size of the ablations were confirmed one week post-treatment via MRI, necropsy, and histological analysis. The animals had almost no side effects and the skin burns were completely eliminated after the first two animal studies, following technique refinement. This study introduces a novel methodology of MRgFUS that can be used to treat deep lung parenchyma in a safe and viable manner.
The Impact of Fourteen Years of UK Conservative Government Policy on Open Access Youth Work
Authors: Davies Bernard
Published: April 2024

This article reviews the impacts of the UK Conservative Party’s government policies on ‘open access youth work’ since 2010, giving particular attention to the period since 2018 and to impacts in England. After clarifying the practice’s distinctive features, it outlines the ‘austerity’ demolition of its local provision and—amid continuing wider financial pressures—changes in the role and contributions of the voluntary youth sector. It lists a range of ‘gesture’ funds for financing responses to young people’s needs and interests as the government has defined them and uses the Youth Investment Fund (YIF) as a case study of how this money has been made available and allocated. Initiatives taken by the Department of Digital, Media, Culture and Sport (DCMS) are then examined: its Youth Review, National Youth Guarantee, review of the statutory guidance to local authorities, and support for ‘youth volunteering’. Two key developments are then considered that, by early 2024, were diverting and inhibiting an even partial sustained reinstatement of the lost open access youth work facilities. One, at the policy level, is the redefinition of ‘youth work’ by governments and by some within the youth work sector itself as a wide range of out-of-school practices with young people; the other, at the point of delivery, is the on-going difficulties in recruiting youth workers, especially those with direct practice experience. Finally, two possible tentative suggestions for some reinstatement of open access youth work provisions are then discussed.

Cmentarz wojenny w Nadolicach Wielkich – trudne dziedzictwo?
Authors: Seń Aleksandra
Published: April 2024

The aim of the article is to examine from a cultural perspective the issue of German war cemeteries in Poland, which were established after 1989 in order to provide the hitherto scattered and devastated burial sites with legal protection.The author addresses the problem of difficult heritage, taking the cemetery in Nadolice Wielkie as an example. She charts the history of the earlier dismantling of German cemeteries, including those from the war, and presents the legal conditions for establishing new Germany necropolises. The second section of the article provides an overview of comments found online regarding the Nadolice cemetery: voices opposing the remembrance of criminals, argued with reports (already disproved) of the burial of members of certain units, as well as frequent opinions of a conciliatory nature. The author concludes by stating that although the spatial organisation of the cemetery is intended to encourage reflection on reconciliation and peace, little is known of its mission, which is linked to the cemetery’s absence in the media.
Kłopotliwe dziedzictwo w turystycznym kontekście. Opolscy przewodnicy i ich strategie narracji o tym, co nieobojętne społecznie
Authors: Kopczak-Wirga Anna
Published: April 2024

The article aims to show the dissonant heritage of Opole from the perspective of tourist guides. Its first section shows the dissonant heritage in relation to tourism, especially cultural tourism, heritage tourism and dark tourism. The role of the tourist guide in constructing narratives about difficult heritage is then considered. Empirically, the article endeavours to identify the elements of Opole’s dissonant heritage discerned by tourist guides, and the ways of telling tourists about them. Ten qualitative interviews were conducted with Opole guides. Analysis of the narratives reveals that the dissonant heritage of Opole is perceived by the guides from several perspectives. This primarily means their own, entangled in the social characteristics of the guide (e.g. national identity), in the context of the specificity of the group that the guide is showing round, and in the context of their reactions to the guide’s stories or sites visited.

Le chemin d'Abel
Authors: Pizzi Paola
Published: April 2024

This research aims to contribute to the study of the current of non-violence in Islam. A phenomenon often considered extraneous to the heritage of this religion, it nevertheless has several examples of commitment, among whom the Syrian preacher and theologian Ǧawdat Saʿīd (1931-2022) deserves particular attention. Central to our work is a reconstruction of his biographical profile as well as an analysis of the development of his theoretical framework over time. Initially a follower of the salafiyyah and then close to the Islamist movement, Saʿīd played a pioneering role in promoting non-violence as the sole modus operandi of an Islamic activism oriented towards the establishment of global peace and justice. Drawing on a social and anthropocentric reading of the Quran, Saʿīd aims to demonstrate that this is the true meaning of revelation and the purpose of the divine eschatological project.

This study investigates the relationship between key director characteristics, board composition, and audit quality in the context of Vietnamese listed firms on the Ho Chi Minh City Stock Exchange over the period 2015 to 2020. Based on the study of Mustafa et al (2017), we employ a comprehensive dataset comprising 415 firms, we utilize a random effects estimation model to analyze the nuances of these associations. Our findings reveal a noteworthy positive relationship between directors aged 36-55 and 46-55 years old and audit quality, suggesting that the experience and expertise of directors within these age brackets contribute positively to the enhancement of audit processes. Furthermore, our study identifies a significant positive impact on audit quality associated with interlocking directorships, emphasizing the importance of interconnected networks within corporate governance structures. In addition, our results highlight the influential role of boards populated by members holding Master's degrees, indicating a positive correlation between educational qualifications and clients' demand for high audit quality. This insight underscores the significance of academic prowess and specialized knowledge in fostering a climate conducive to rigorous audit practices.
IDENTIFYING DECEPTIVE FINANCIAL REPORTING VIA ANALYSIS OF FINANCIAL STATEMENTS: CASE IN VIETNAM
Authors:   Nguyen Tat Thanh University, Phong Lan Nguyen Ngoc
Published: April 2024

Deceptive financial reporting represents a significant worry for the main regulatory bodies overseeing Vietnam's capital market. Both regulatory bodies are continuously enhancing the criteria to ensure thorough monitoring of publicly listed companies. The objective of the current study is to investigate the link between financial statement analysis and fraudulent financial reporting. While numerous researchers have uncovered evidence suggesting the effectiveness of financial ratios in identifying fraudulent financial reporting, others have reached differing conclusions. The majority of these studies were conducted beyond the borders of Vietnam. The sample consists of companies listed in Vietnam, and the data utilized spans from 2011 to 2022. The findings revealed that various financial ratios, including total debt to total assets and receivables to revenue, emerged as significant indicators for identifying fraudulent financial reporting. This suggests that financial ratios could potentially aid in detecting fraudulent activities. These results contribute to the existing body of literature concerning the efficacy of financial ratios in fraud detection.

In the modern world, the use of information technology (IT) is becoming increasingly important for the effectiveness of employment support programs. However, existing theories such as human capital theory and theories related to technological change and skills emphasize that skill development is a key factor for success in the labor market. This text examines the impact of digitalization on labor relations and the labor market. Discusses changes brought about by digital transformation, including the transition to flexible forms of employment and remote work. The need to adapt the education system to new requirements is emphasized and the role of the state, employers and workers in the humanization of social and labor relations is considered. Attention is also drawn to the problems of discrimination in the labor market caused by digital technologies. In conclusion, the significance of changes in the world of work and the need to formalize and strengthen them in legislation are noted.

Bolsonaro’s supporters used social media to spread content during key events related to the Brasília attack. An unprecedented analysis of more than 15,000 public WhatsApp groups showed that these political actors tried to manufacture consensus in preparation for and after the attack. A cross-platform time series analysis showed that the spread of content on Twitter predicted the spread of content on WhatsApp. Twitter also predicted news coverage of Bolsonaro’s supporters, suggesting a propaganda feedback loop. Our findings indicate that investigative journalism and public policy initiatives could benefit from monitoring public groups on encrypted messaging apps.

Published: April 2024

Little is known about the importance of different variables in shaping cyclists' risk perception when cycling in urban areas. The aim of this study was to evaluate the effects of environmental and demographic factors on cyclists' perception of risk in urban cycling. We conducted a study in the central area of a large city, Qazvin, Iran. A linear mixed model was developed to predict the cyclists’ angular movement. Twenty-six cyclists were included in this study. The outcome variable was the change in the cyclists' angular movement as a surrogate for risk perception, and the predictors were the personal characteristics and environmental features. Cycling through residential and commercial areas, one-way routes, routes with speed limits, wide routes ≥ 12 m, existing bike lanes, traffic volume, and path elevation (all P≤0.001) are associated with angular movement. However, sex, age, cycling history, psychological distress score, and presence of parks are not significant predictors of the angular movement. While the cyclist characteristics do not show significant correlations with the angular movement, environmental factors have significant effects on the cyclists’ risk perception. Our research provides insight into the factors that influence the cyclists’ risk perception in urban areas. Environmental factors have significant impacts on the cyclists’ risk perception. This study highlights the critical role of cycling infrastructure in shaping the cyclists’ risk perception and it provides implications for urban planners and policymakers.

Published: April 2024

The Indonesian government has allocated 30 billion rupiahs in 2020 to revitalise Huta Siallagan, a traditional village on the borderline of Lake Toba, in order to support the national development agenda. The revitalisation is carried out to increase the attractiveness of the destination by reorganising the area and improving the facilities. Traditional villages in Lake Toba are typically acres of land owned and lived on by a single-family clan, which manages tourism activities through family members. As Huta Siallagan receives significant attention from the government, this study seeks to examine the managerial modifications and adjustments following the finished revitalisation project. This study employs a sustainable tourism framework from the Global Sustainable Tourism Council (GSTC). The findings are juxtaposed with the model of sustainable traditional village revitalisation that has been widely used as the basis for integrating rural tourism into tourism growth. The result of this study provides knowledge in the sustainable tourism literature, particularly in the context of village revitalisation for tourism purposes. It also highlights, from a practical standpoint, the subsequent challenges that arise in traditional village revitalisation projects. The study then identifies solutions to minimise internal and external conflicts in tourism governance.

In the forest-steppe zone of the Middle Volga region, precocity, shortness of stem and resistance to lodging are important economic and biological signs that affect the productivity of wheat in a certain way. The object of research was 300 collectible samples of spring soft wheat of domestic and foreign origin. Field experiments were laid in 2019-2021 on the basis of the laboratory of breeding and seed production of spring wheat of the Volga Research Institute of the Russian Academy of Sciences on the fields of the first selection crop rotation. As a result of research in 2019-2021, the duration of the germination-earing period (PVK) in collection samples varied from 31 to 52 days. In 2020, a weak negative relationship was revealed between the duration of PVK and the yield of samples (r = -0.18) with a critical value of coefficients r005 = 0.113, r001 = 0.148, in 2021 – an average negative relationship between PVK and the yield of samples (r = -0.35). On the basis of precocity, 13 genetic sources were identified: 2019 - Ural Cuckoo, Chelyabinsk Early (Chelyabinsk region), Odeta, Libertina (Czech Republic), Chi Mai (China); 2020 - Rifor 1, Rifor 6, LT-9 (Leningrad region), Arabeska (Poland); 2021 - Albidum 2030 (Orenburg region), Odintsovo (Chelyabinsk region), Dalira (Khabarovsk region), Zarco (Spain).Over the years of research, the height of plants in the studied samples by the end of the growing season varied from 40 to 124 cm. Short-stem varieties and hybrids were mainly of foreign origin. 15 genetic sources were identified based on shortness of stem: 2019 - KWS Torridon (Great Britain), KWS Jetstream (Germany), Florens, Eleganza (France), Long Fu 13 (China); 2020 - Odeta, Libertina (Czech Republic), Shiraz (Great Britain), Bryza (Germany), Boett (Sweden), Iona (USA); 2021 - H15-3 (Lipetsk region), KWS Sunny (Germany), Stanga (Switzerland), Dian 852-184 (China). The selected samples are recommended to be used in the breeding process.
The coevolution of Covid-19 and host immunity
Authors: Haque Azizul , Pant Anudeep B.
Published: April 2024

The dynamic of the virus-host interaction is subject to constant
evolution, which makes it difficult to predict when the SARS-CoV-2 pandemic
will become endemic. Vaccines in conjunction with efforts around masking and
social distancing have reduced SARS-CoV-2 infection rates, however, there
are still significant challenges to contend with before the pandemic shifts
to endemic, such as the coronavirus acquiring mutations that allow the virus
to dodge the immunity acquired by hosts. SARS-CoV-2 variants deploy
convergent evolutionary mechanisms to sharpen their ability to impede the
host’s innate immune response. The continued emergence of variants and
sub-variants poses a significant hurdle to reaching endemicity. This
underscores the importance of continued public health measures to control
SARS-CoV-2 transmission and the need to develop better second-generation
vaccines and effective treatments that would tackle current and future
variants. We hypothesize that the hosts’ immunity to the virus is also
evolving, which is likely to abet the process of reaching
endemicity.
Efficient 32-nm CNTFET-Based 1-Bit Adder: A Fast and Energy-Optimized Design
Authors: Tirumalasetty Venkata Rao , Babulu K. , Naidu G. Appala
Published: April 2024

CNTFETs are a shows potential choice for traditional CMOS technology due to their potential for lesser power consumption and superior performance. In the present paper, a new 1-bit hybrid full adder has been deliberated and proposed using both pass transistor (PT) and transmission gate logics (TGL), which utilizes a total of 16 transistors. The combination of PT and TGL can lead to improved power efficiency, reduced delay, and enhanced circuit performance in various VLSI applications. For 0.9 V supply voltage at 32-nm CNTFET technology, the power consumption is 0.0748 μW, which is to be an exceptionally low value with a lesser delay of 7.586 Ps and the power-delay-product (PDP) of 0.5674 aJ. The results obtained from this analysis demonstrate the power efficiency, speed, and overall performance of the proposed full adder design. The combination of 32-nm CNTFET technology, deliberate circuit design choices, and the use of specific logic elements (CMOS inverters and strong transmission gates) contributes to the reported characteristics. Using a 0.9 V supply voltage and 32-nm Stanford CNTFET Model technology, the suggested 1-bit adder circuit's concert was investigated using the Mentor Graphics Tool. Finally, using the proposed 1-bit full adder circuit, an N-bit ripple carry adder (N=8, 16 & 32) is implemented and demonstrated. The Simulation results of the 8-bit RCA with a power consumption of 0.373 μW, the delay is 16.852 Ps and the PDP is 6.2857 aJ. These results show that proposed RCA’s have better performance compared to the already reported designs in terms of performance, speed, and power economy.
On Period Annuli and Induced Chaos
Authors: Atslega Svetlana , Kozlovska Olga , Sadyrbaev Felix
Published: April 2024

Nontrivial period annuli in the second order ordinary differential equation are continua of periodic trajectories that contain inside more than one critical point. They can appear in conservative equations, which are known to have no attractors. Nevertheless, according to some authors, their behavior may be done chaotic by adding a periodic external force. Is the period of the external force correlated with periods of solutions in period annuli? Is the chaotic behavior of a solution dependent on the initial value and, in turn, on a certain periodic annulus? These, and related questions are studied in the article.
