Global Stability and Bifurcation Analysis in a Discrete-Time Two Predator-One Prey Model with Michaelis-Menten Type Prey Harvesting
Authors: MUKHERJEE Debasis
Published: April 2023

This article studies a discrete-time Leslie-Gower two predator-one prey system with Michaelis-Menten type prey harvesting. Positivity and boundedness of the model solution are investigated. Existence and stability of fixed points are examined. Using an iteration scheme and the comparison principle of difference equations, we find out the sufficient condition for global stability of the positive fixed point. It is shown that the sufficient criterion for Neimark-Sacker bifurcation can be developed. It is observed that the system behaves in a chaotic manner when a specific set of system parameters is chosen, which are regulated by a hybrid control method. Examples are provided to illustrate our conclusions.

Authors: Czapran Tomasz
Published: April 2023

Purpose: is the issue of managing an age-diverse workforce in a company or enterprise.

Method: the article used the method of empirical calculations.

The results of the study: during the research it was established that teams are most productive when they are not made up of the same people,  people in the team must be able to work together and respect each other, but at the same time, they should represent different qualities, experiences, and skills that will complement each other for the benefit of the whole team.

Практична цінність дослідження: Cooperation within age-diverse teams increases the value of group or team IQ. It has been empirically proven that the element which most significantly affects group IQ is not the average IQ of individual group members, but rather the level of their emotional intelligence. The key to a high group IQ is harmony in the relationships of group members, communication skills and receptivity.

Published: April 2023

The purpose of this collaborative social research also called action research action was to explore the perception of college professors from more than a dozen universities from different regions of post-conflict Somalia, their perception and openly teaching international electoral policy and practice (EPP), in the post-conflict Somalia’s classroom or in the public sphere. In addition, this action research study sought to develop understanding, meaning and root-cause analysis process in human performance in uncontrolled variations as the university lecturers displayed reluctance of teaching democracy related content for fear of public backlash due to the ideological divide. Methodologically, the author utilized Emerson, Fretz & Shaw (1995) observation protocol to gather data for analysis to reveal the perception of the 19 educators from 19 universities, and most importantly, on making informed decision on what the next step would be. The setting where the research took place was a training seminar on international electoral policy and practice (EPP), designed to teach the university lecturers from post-conflict Somalia. How the Somali educators can overcome the methodological, cultural and religious challenges when incorporating democracy related materials into the curricula in Somalia to boost the educational campaign on elections in Somalia which did not go to polls to freely elect a leader since 1967 elections. The author proposed The Culturally Competent Integrative Curriculum Approach to overcome the methodological dilemma.

— The need to develop alloys with enhanced properties that will perform efficiently has continually become the major concern. In this study, the influence of Ti addition on the microstructure and mechanical properties of Cu-10Ni alloy was investigated. Cu-10Ni alloy was altered by adding Ti in the concentrations of 0.1, 0.2, 0.3, and 0.4wt%. The as-cast samples of Cu-10Ni alloy were solution treated at 900oC for 2 hr, quenched in water, and then aged at three different temperatures (400oC, 450oC and 500o ) for 2hr. Microstructural characteristics were observed using metallurgical microscope, and scanning electron microscope equipped with EDS, while tensile strength, hardness, impact strength and ductility as a function of mechanical properties were determined. Adding Ti contents in Cu-10Ni alloy and ageing at different temperatures greatly increased the properties and grain refinement of the alloy. The improvement in properties were due to slight promotion of precipitation and occurrence of enhanced TiNi3 particles after ageing treatment. The as-cast Cu-10Ni alloy had a peak value of 163MPa tensile strength, 127BHN hardness, and 142J impact strength at 0.1%Ti. Under the ageing condition, the samples with 0.4%Ti had peak tensile strength, hardness, and impact strength values of 574MPa, 193BHN, and 138j, respectively. The variation in the values of the tested properties of the alloys was measured on the role of the ageing temperature. The Ti addition promotes the growth of precipitates, which refines the microstructure during the ageing process and results in an excellent improvement of the properties of the Cu-Ni alloys.

Published: April 2023

This article takes a close look at how women's cooperatives may empower women. The paper examines the prospects and barriers to women's empowerment in environments lacking an enabling macro-institutional framework and societal structure by drawing evidence from a variety of women's cooperatives in the province. We investigate the ways and degrees to which members sense empowerment in their lives after joining the cooperatives by listening to the real-life accounts of women from various socioeconomic and political backgrounds. We discover that women nonetheless feel economic, psychological, social, and organizational empowerment despite societal and governmental restrictions, while the degree of this empowerment differs among cases.

Low-cost multimode fiber (MMF) optic sensor for detection and determination of adulterant traces of palm oil in coconut oil is experimentally demonstrated. The fundamental principle of detection is the sensitive dependence of the wavelength shift on the refractive index changes of the surrounding medium of multimode fiber cladding. The transmission spectral changes due to variation of adulteration levels have been investigated. Building up of this low-cost multimode fiber optic sensor is helpful in prevention of adulteration. This technique has resulted in 20% adulteration for coconut-palm oil binary mixture

Authors:   Institute of Oriental Studies of the Russian Academy of Sciences, Moscow, Russian Federation, GUTENEV YURIY
Published: April 2023

The article examines the approach of the Russian Federation to the growth of terrorism affecting international relations over the past two decades. The article assesses the impact of this threat on the security of our country, on the international situation, and analyzes the decisions taken by the Russian leadership on this issue. The author attempts to consider and describe the influence of the Russian Federation on the ongoing domestic and foreign policy events related to terrorism and religious extremism, designated by the President of the Russian Federation. Attention is also paid to the reasons changing this approach to security in the Russian Federation over the past twenty years. The reasons for the development of new systems of countermeasures by Russia, its entry into a new era of relations with other states, despite their differences, are considered. In turn, the author wants to draw attention to such questions as: “Why is Russia forced to respond to challenges and threats and constantly improve its legislative framework and what changes have taken place in the field of its information security?”. Official documents, United Nations resolutions, sources and scientific works are analyzed in the context of the approach to ensuring security against terrorism. The study shows that the number and quality of threats will continue to increase as terrorist groups gain experience and hone their skills. The fight against terror is possible only in the long term with high-quality international cooperation between States and in the absence of double standards.
CAREER PORTFOLIO: IMPACT OF ALTERNATIVE TYPES OF LABOR AND NON-STANDARD FORMS OF LABOR BEHAVIOR ON THE LEVEL OF SECONDARY EMPLOYMENT IN RUSSIA
Authors:   Volgograd Branch of Plekhanov Russian University of Economics, Volgograd, Russian Federation, OKHREMENKO IRINA
Published: April 2023

Today, employers and employees often move away from the model of traditional employment, i.e., performance of work within the framework of labor relations between the employee and the employer hiring them based on an open-ended employment contract, at fixed hours, in accordance with generally accepted labor standards. The purpose of the study is to identify the alternative types of labor and non-standard forms of labor behavior existing in the secondary employment market in Russia. Based on a literature analysis and an expert survey, the study shows that non-standard forms of employment are becoming increasingly popular in the modern labor market. They include employment not regulated by an employment contract, employment for a certain period, part-time employment, irregular working hours, as well as working outside the employer’s location. Over the past decades, the development of alternative types of labor and non-standard forms of employment has become one of the most important phenomena in the modern labor market. It is expected to play a leading role in increasing the flexibility of the labor market.

Results of the first practical application Brolucizumab for the treatment of neovascular age-related macular degeneration
Authors: Kuranova O. I. , Guseva E. V. , Antonuk V. D.
Published: April 2023

Introduction. Today the standard of treatment neovascular age-related macular degeneration is frequent intravitreal injections of antibodies to vascular endothelial growth factor. Brolucizumab is one of these medicines, which is a single-chain humanized antibody variable fragment with a very small molecular weight (26 kDa). In our country, there are quite a few publications about the results of using Brolucizumab in the Russian Federation due to the fact that this drug began to be used recently (since mid-2021).

Purpose: to evaluate our own experience with Brolucizumab treatment of neovascular age-related macular degeneration (nAMD).

Materials and methods. The study included 25 patients with nAMD for the period from September 2021 to June 2022, among them 17 women, 8 men, the average age of the patients was 77.07 ± 4.88 years. All patients were divided into 2 groups. The first group included 15 patients previously treated with Ranibizumab. The second group included 10 patients who had not previously received anti-angiogenic therapy. All patients underwent an average of 2 or more IVIs of Brolucizumab and a standard ophthalmological examination, as well as optical coherence tomography (OCT) at the first checkup and one month after each IVI with using the Nidek RS-3000 Advance Angioscan device (Nidek, Japan). All patients included in this study signed an informed consent for it.

Results. Almost all patients during the anti-angiogenic therapy with Brolucizumab showed an improvement in anatomical and functional parameters. In the first group the average visual acuity at the time of data analysis increased by 12.7% compared to the baseline, while in the second group - by 57%. The average thickness of the central retina zone in patients of the first group decreased by 13.8% compared to the initial one, while in the second group by 50.9%. During the study period, one case of an adverse event in the form of moderate vitreitis was registered, which occurred on the 8th day after the fourth IVI of Brolucizumab, previously the patient received two IVIs of Ranibizumab. At the time of data analysis, the patient continued to receive anti-inflammatory therapy with positive dynamics in terms of stopping the symptoms of vitreitis.

Conclusion. This study showed the high efficacy of Brolucizumab in the treatment of nAMD, which was manifested by an improvement in anatomical and functional parameters in patients of both groups. However, the treatment efficacy was higher in patients without previous antiangiogenic therapy. The resulting case of side effect in the form of intraocular inflammation requires a deeper analysis in order to correctly select patients for IVI in the future.

Published: April 2023

Currently, there is a significant shortage of donor materials for replacing corneal tissue that is why it is relevant to create xenomaterials, which are able to replace a donor cornea with various types of keratoplasty. “Corneoplast” is a new medical device, which is a devitalized, fixed by the method of double crosslinking (dehydrothermic + UV), pork cornea.

Purpose: to assess the biocompatibility and ability to integrate with the recipient cornea of implants based on the xenomaterial “Corneoplast”.

Materials and methods. The experiment was based on biomicroscopy examination, high-resolution optical coherence tomography and histological examination of the experimental rabbits’ corneas (group I–IV: total of 8 eyes were examined), where keratoplasty was performed with the “Corneoplast” material.

Results. High biocompatibility and ability to integrate with the recipient’s cornea were observed in all types of keratoplasty: penetrating, superficial lamellar and intralamellar keratoplasty. On the next day, the implant was transparent with slight swelling of the recipient’s corneal stroma. A week later, the slight swelling of implant was recorded without cornea edema. Its transparency decreased. The recipient’s cornea was reactive. A month later, the moderate neovascularization was noted towards the sutures. After 6 months, the recipient’s cornea was clear, transparent. The implant was translucent and neovascularization was absent. The entire surface of cornea and implant was epithelialized. On the series of optical coherent tomograms, a normal thickness of the epithelium continuous layer was determined in 6 months after the surgery. The complete integration of material with the recipient’s cornea was noted. The layered structure characteristic of corneal tissue was preserved. The cornea retained a layered structure and the endothelium was preserved. On histological examination, there were no differences in the intact cornea and implanted material.

Conclusion. The “Corneoplast” material is sufficiently biocompatible and capable of integration with the recipient’s cornea in an animal experiment. This allows, at a certain stage of preclinical trials completion, to use it for replacing corneal tissue in penetrating keratoplasty, intralamellar and superficial anterior layer-by-layer implantations and to cover purulent corneal ulcers of various depths.

Authors: Zharkov V.A.
Published: April 2023

The theory of stamping is developed taking into account the anisotropy and hardening of the workpiece. The calculation of the parameters of the deformed-stressed state of the billet is carried out using the example of bending on a roller machine or in a die. Deformations, stresses and forces acting on the billet from rolls or die tools are studied by CAD/CAE modeling. The criteria for crack formation, low accuracy and excessive springback of the part after processing are determined, recommendations for their elimination are given.

Fusing Intelligence and Strategy Capabilities: The MIQ Experience
Authors: Kay Harriet , Paul Keymer , Mckey Sarah , Vickers Shae
Published: April 2023

New Zealand’s Managed Isolation and Quarantine (‘MIQ’) was a rapidly established, distributed isolation and quarantine capability, designed to maintain the restricted international movement of people into New Zealand between April 2020 and August 2022 and to provide some of these services to those in our communities. The rapid establishment of this complex function (in addition to the fast-changing COVID-19 landscape) led to the requirement for quick operational decisions, with strategic impacts, often being made with limited information. The MIQ Future Strategy Team (FST) was established in August 2021 to enhance MIQ leadership’s ability to make robust future-focused strategic decisions. It successfully achieved this by (uniquely) establishing an intelligence and strategy ‘fused’ capability, delivering integrated planning and predictive analysis in a manner not achievable via a single discipline. Its success demonstrated the compound value of fusing complementary business functions and adopting intelligence functionality within business environments unfamiliar with these concepts. This article explores how this was achieved, conveys lessons identified through this journey and describes three case studies which highlight FST outputs.

Authors: Edema Patrick Kelele , Ogwezi Joyce Ogho
Published: April 2023

The study interrogates how the media mounted pressure on state actors to review weak anti-graft legislation in Nigeria. Content analysis was adopted for the study, while 1,520 hard copies of the Daily Sun, The Nation and Daily Trust as well as Vanguard and The Punch newspapers published from 2015-2019 were examined. The study was anchored on Framing Theory. Data collected were presented in tables and frequencies and were analyzed with the ANOVA statistical tool. Findings indicate that there was no significant difference in the degree of pressure mounted on state actors by the newspapers to review weak anti-corruption laws. The study recommends that media organizations must re-calibrate their editorial policies aimed at pressurizing state actors into addressing loopholes inherent in the legal framework in the fight against sleaze in the country.
