In this paper, we observed the ordinary differential equation (ODE) system and determined the equilibrium points. To characterize them, we used the existing theory developed to visualize the behavior of the system. We describe the bifurcation that appears, which is characteristic of higher-dimensional systems, that is when a fixed point loses its stability without colliding with other points. Although it is difficult to determine the whole series of bifurcations that lead to chaos, we can say that it is a common opinion that it is precisely the Hopf bifurcation that leads to chaos when it comes to situations that occur in applications. Here, subcritical and supercritical bifurcation occurs, and we can say that subcritical bifurcation represents a much more dramatic situation and is potentially more dangerous than supercritical bifurcation, technically speaking. Namely, bifurcations or trajectories jump to a distant attractor, which can be a fixed point, limit cycle, infinity, or in spaces with three or more dimensions, a foreign attractor.

Aim: This paper presents a qualitative study of the experiences of parents raising children with autism, as reflected in the media. The study aimed to explore the lived experiences of parents of children with autism and the challenges they face in Bosnia and Herzegovina. Methods: A content analysis of 20 media articles featuring parents of autistic children was conducted. The articles were selected from a range of sources, including newspapers, magazines, and online news portals. Results: We identified four major themes: supports, education, spousal relationships, and future. It should be noted that these themes are often intertwined. Conclusion: The findings highlight the importance of providing support and resources to parents of children with autism, as well as the need for greater awareness and understanding of the challenges they face. The implications of these findings for policy and practice are discussed, and suggestions for future research are presented.

This paper describes the first record of the critically endangered gravid female Spiny butterfly ray, Gymnura altavela (Linnaeus, 1758), in the northern Mediterranean and simultaneously the only record of the species in this century for the Adriatic Sea. The female (173 cm disc width and 43.25 kg total weight) was captured at approximately 200 m, off Vlorë in the southern Adriatic Sea off Albania on 12th of May 2022. Upon necropsy, seven near-term fetuses (mean 328 ± 6.47 mm disc width and mean 355 ± 20.06 g in total weight) were transported for further in-vitro incubation. These results represent the deepest capture for the species, as well as the largest litter size and largest size at birth in the Mediterranean Sea which indicates the need for further research.

The present age is moving through Industry 4.0 with massive technological developments. Supply chains have become digital, keeping sync with consumer demands and preferences. The recent pandemic has reinforced the need of embracing digital technologies in managing supply chains effectively. Therefore, it is necessary that supply chains adopt 5G mobile technologies. In this regard, the present study aims to discern the critical issues for the successful adaptation of 5G technologies for supply chain management (SCM) in developing countries such as India. The success factors for the adaptation of 5G in Indian supply chains are derived from the discussions made in the related past work regarding the challenges of implementing 5G technology. Then, the listed factors are finalised through initial rounds of face-to-face discussions with a focus group of five experts. Then, a q-rung-orthopair-fuzzy (qROFS)-based rating scale is used to rate the success factors. A new qROF-weighted-neutrality-average (q-ROFWNA)-based full-consistency method (FUCOM) approach for multicriteria decision-making (MCDM) problems involving group decision making is utilised to find out the critical success factors. Based on the comparative analysis of 17 success factors (grouped into four main factors), the spectrum availability, awareness of technology and usage, the development of supporting technologies and smart cities, and skill development are found to be the top five critical factors for the successful adaptation and implementation of 5G technologies in SCM. We further carry out a sensitivity analysis and validation test and observe that our model provides a reliable and stable solution.

Introduction: Preoperative carbohydrate oral (CHO) drinks attenuate the surgical stress response; however, the effects of CHO supplementation on the neutrophil-to-lymphocyte ratio (NLR) as an inflammatory and immunology-based predictor remain unclear. This study evaluated the effects of preoperative CHO loading on NLR values and complications following open colorectal surgery compared with a conventional fasting protocol. Methods: Sixty eligible participants having planned for routine and open colorectal cancer surgery from May 2020 to January 2022 were prospectively and randomly allocated to either the control (fasting) group, whose members discontinued oral intake beginning the midnight before surgery, or the intervention (CHO) group, whose members consumed a CHO solution the night before surgery and 2 h prior to anaesthesia. NLR was assessed at 06:00 h before surgery (baseline) and at 06:00 h on postoperative days 1, 3, and 5. The incidence and severity of postoperative complications were assessed by Clavien-Dindo Classification up to postoperative day 30. All data were analysed using descriptive statistics. Results: Postoperative NLR and delta NLR values were significantly higher in controls (p < 0.001; p < 0.001). Control group participants also demonstrated grade IV (n = 5; 16.7%, p < 0.01) and grade V (n = 1; 3.3%, p < 0.313) postoperative complications. There were no major postoperative complications in the CHO group. Conclusion: Preoperative CHO consumption reduced postoperative NLR values and the incidence and severity of postoperative complications following open colorectal surgery, compared with a preoperative fasting protocol. Preoperative carbohydrate loading may improve recovery following colorectal cancer surgery.

Two copper(II) complexes of 4-chloro- and 4-dimethylaminobenzaldehyde nicotinic acid hydrazones were prepared and characterized by elemental analysis, mass spectrometry, infrared and electron spectroscopy and conductometry. These rare examples of bis(hydrazonato)copper(II) complexes are neutral complex species with copper(II) center coordinated with two monoanionic bidentate O,N-donor hydrazone ligands coordinated in enol-imine form. The interaction of hydrazone ligands and corresponding copper(II) complexes with CT DNA and BSA was investigated. Copper(II) complexes are slightly effective in binding the DNA than pristine hydrazones. The results indicate groove binding or moderate intercalation which are not significantly affected by the nature of substituent at hydrazone ligands. On contrary, affinities of two copper(II) complexes toward BSA significantly differs and depends on the nature of the substituent, however in absence of thermodynamic data difference in nature of binding forces cannot be excluded. The complex bearing electron-withdrawing 4-chloro substituent has larger affinity toward BSA compared to 4-dimethyamino analogue. These findings were theoretically supported by molecular docking study.
