The investigation of thermal stability and GC-MS analysis of Acorus tatarinowii and Atractylodes lancea volatile oils treated by β cyclodextrin inclusion and Pickering emulsion technologies

ObjectiveTo investigate the stability of Acorus tatarinowii and Atractylodes lancea essential oils (ATaAL-EO) under a hot environment at 60 °C, and to analyze the differences in component, quantity, and quality changes, as well as variations in the main components, under different treatment methods of crude oil, β-cyclodextrin inclusion of ATaAL-EO, and Pickering emulsion, to improve the stability and quality of ATaAL-EO. MethodsThe stability of the ATaAL-EO group, the β-cyclodextrin inclusion ATaAL-EO group, and the Pickering emulsion group were investigated under a 60 °C heat environment. Volatile oil retention rate and peroxide value were collected and measured. The volatile oil components of each group were determined by GC-MS, and t-tests were used to screen for differential components. PCA plots for each group were constructed using the OmicShare online platform. Line plots were generated using the Rmisc and reshape2 packages. Upset Venn diagrams under different hot environments were created using the OmicShare online platform to identify quantitative and qualitative changing components and heat map stack plots for newly generated compounds and connected line plots for disappearing compounds were produced for each group. Boxplots for the main component compounds under different hot environments were generated using the reshape2 and ggplot2 packages. ResultsIn a hot environment of 60 °C, the β-cyclodextrin inclusion ATaAL-EO and Pickering emulsion group with 1, 3, and 8 h of placement showed higher retention and lower oxidation degree compared to the stability of the ATaAL-EO group. GC-MS analysis results showed that the stability of volatile components in the Pickering emulsion group and β-cyclodextrin inclusion ATaAL-EO group was significantly improved compared to the crude oil group. Conclusionβ-cyclodextrin inclusion complexes with ATaAL-EO, as well as Pickering emulsions, can significantly enhance the stability and quality of ATaAL-EO. Pickering emulsions have more advantages.

Non-stationary stochastic response determination of vibro-impact system under combination harmonic and Gaussian white noise excitations

Vibro-impact system (VI-S) have demonstrated their potential to contribute to engineering practice throughout the last few years. Nonetheless, their scope of application are still very limited. One of a primary reason is that dynamic behaviors of VI-S under the combination of deterministic period excitations (deterministic period excitation) and random noises (random noises) are not entirely understood. Toward this, the radial basis function neural network (rbfnn) is used to analyze dynamical behaviors evolution of VI-S under deterministic period excitation combined with random noises. To illustrate the potential of the proposed scheme, two classical examples of Mathieu–Duffing oscillator and Duffing–Rayleigh oscillator are considered. The evolutionary of dynamics behaviors and stochastic P-bifurcation phenomenon are examined through a qualitative change of the probability distribution, which indicates that system parameters and noise intensity, respectively, can be treated as bifurcation-induced parameters. Besides, numerical results are also carried out to confirm the accuracy of semi-analytical prediction.

SUSTAINABLE DEVELOPMENT MANAGEMENT OF CULTURAL ORGANIZATIONS IN MODERN CONDITIONS

The article is focused on the issues of sustainable development management of cultural organizations in modern conditions. In the framework of the research, it is identified that the concept of sustainable development of these organizations can be considered from the standpoint of both their functional role (producers, repeaters, carriers of the "culture of sustainable development") and organizational development itself (qualitative changes that form the conditions for the system’s transition to a new level of development while maintaining a balance in the triad of "economic-social-environmental goals"). It is determined that exogenous and endogenous factors in modern conditions form a number of risks and threats, which makes both the entire system of institutions in the field of culture and its individual subsystems and organizations to adapt to new conditions of activity more rapidly. At the same time, ensuring sustainable development through the use of modern management tools is becoming increasingly relevant. It is identified that the vector of environmental factors, the level of uncertainty in decision-making and the available resource potential have a greater impact on the nature of sustainable development management tools. It has been identified that despite the negative environmental conditions, such management is becoming strategic, organizations are gradually switching to the use of crisis and project management, adapting to the use of a market approach to organizing their sustainable development. The author proposes directions for further scientific and applied research that can lay the groundwork for improving the efficiency of sustainable development management and making it systematic in the activities of cultural organizations.

Time of Change in Plato and Aristotle

Abstract When do things change? When do things have some characteristics? I try to answer these questions by looking at different solutions Plato and Aristotle presented in their works. The famous analysis of change from the second half of Plato’s Parmenides claims that change happens outside of time, at an “instant”. On the contrary, Aristotle in the Physics explicitly argues that all change occurs only in time. However, both Plato and Aristotle also provide other analyses of change. How to deal with this variety of explanations and tensions between them? In this paper, I argue that if we differentiate between several kinds of change, most of Plato’s and Aristotle’s analyses provide a thorough insight into the nature of change. For processes such as locomotion, change occurs exclusively within time. For changes where both the initial and final states occur only in time, such as a transition from motion to rest, change takes place in the ‘now’. However, for changes where both the initial and final states occur in both time and in the ‘now’ – for example, a qualitative change from being white to not being white – change does not occur in time nor in the ‘now’, but instead happens instantaneously.

Effect of Blanching on Drying Kinetics and Quality of Solar Dried Cabbage

Cabbage (Brassica oleracea var. capitata) 250 g samples were blanched in water at 100˚C for 2 min, and subjected to solar cabinet drying to observe qualitative changes of the dried product. Blanching pre-treatments were done in plain water for 2 min (T1 ), and 0.5% potassium metabisuphite (T2 ). Sample without blanching was considered as control ( UT ) . The samples were then dried in a solar cabinet dryer (57 ±3˚C) . Six thin layer drying models were used to fit the experimental moisture ratio obtained for cabbage by nonlinear regression analysis using NLREG Statistical programme. Page model showed a good fit with the highest correlation for cabbage samples. Solar cabinet dried product were found good and acceptable in sensory quality. Cabbage blanched in KMS solution was the best, followed by blanching in water. The rehydration ratio (5.5) and coefficient of rehydration (0.488) were highest for cabbage blanched with KMS solution among all samples. The result showed that the rehydrated products could be well utilized for substituting the fresh product in off-season.

Newborn Hospitalizations Before and During COVID-19 Pandemic in Poland: A Comparative Study Based on a National Hospital Registry.

Objectives: There are limited data on the impact of the COVID-19 outbreak in Poland on newborn health. The aim of the study is to show recent information on hospitalizations of newborns in Poland in the pre-pandemic and COVID-19 pandemic era. Methods: A retrospective, population-based study was conducted using data from hospital discharge records of patients hospitalized in 2017-2021. Results: The data on which the study was based consisted of a substantial number of 104,450 hospitalization records. Annual hospitalization rate was estimated to be 50.3-51.9 per 1,000 in 2017-2019, 56 per 1,000 in 2020 and it rose to 77.7 per 1,000 in 2021. In comparison to the pre-pandemic period, in the COVID-19 era, we observed significantly more hospitalization cases of newborns affected by maternal renal and urinary tract diseases (p < 0.001), syndrome of infant of mother with gestational diabetes (p < 0.001), maternal complications of pregnancy (p < 0.001). In the COVID-19 era, the prevalence of COVID-19 among newborns was 4.5 cases per 1,000 newborn hospitalizations. Conclusion: The COVID-19 pandemic outbreak could significantly contribute to qualitative and quantitative changes in hospitalizations among newborns.

Assessment of quadriceps muscle mass by ultrasound in the postoperative period of cardiac surgery

BackgroundPatients undergoing cardiac surgery are exposed to many factors that activate catabolic and inflammatory pathways, which affect skeletal muscle and are, therefore, related to unfavorable hospital outcomes. Given the limited information on the behavior of muscle mass in critically ill patients, the objective of this study was to evaluate the impact on quantitative and qualitative measurements of quadriceps muscle mass using ultrasound after cardiac surgery. To accomplish this, a prospective, descriptive, and correlational study was conducted at a tertiary care hospital. Quadriceps muscle mass was evaluated via ultrasound in 31 adult patients in the postoperative period of cardiac surgery, with daily follow-up until postoperative day 7, as well as an assessment of associations with negative outcomes at 28 days.ResultsA 16% reduction in the cross-sectional area of the rectus femoris was found (95% CI 4.2–3.5 cm2; p 0.002), as well as a 24% reduction in the pennation angle of the rectus femoris (95% CI 11.1–8.4 degrees; p: 0.025). However, changes in the thickness of the rectus femoris, vastus internus, vastus lateralis, the length of the fascicle of the vastus lateralis, the pennation angle of the vastus lateralis, the sarcopenia index, and the Hekmat score were not statistically significant. There was no significant association between quadriceps muscle mass measurements and Intensive Care Unit (ICU) length stay or 28-day mortality.ConclusionsPatients in the postoperative period of cardiac surgery evaluated by ultrasound exhibit both quantitative and qualitative changes in quadriceps muscle mass. A significant reduction in muscle mass is observed but this is not associated with unfavorable outcomes.

From alliance to ‘soft conquest’: the anatomy of the Turkish-Azerbaijani military alliance before and after the 2020 Nagorno-Karabakh war

ABSTRACT Military cooperation has been one of the milestones in Turkish-Azerbaijani relations since the early 1990s. A qualitatively new phase began in 2010 after the signing of the strategic agreement which not only fixed the ʹcasus foederisʹ clause but also significantly increased the scope and volume of cooperation. Military cooperation underwent a qualitative change and Turkeyʹs participation in the modernization of the Azerbaijani army gained key importance. The goal of this article is to identify the qualitative changes and transformations in military cooperation and examine their direct and indirect impact on the process of transformation of the identity of Azerbaijani society.

Трансформация системы стратегических коммуникаций предприятий легкой промышленности и индустрии моды

The fashion industry has to update collections extremely fast, which leads to resource depletion in the absence of demand. Moreover, environmentally-aware consumers tend to associate this accelerated production cycle with environmental pollution. As a result, the growing public interest in green materials and lean manufacturing increases the popularity of brands that are associated with sustainable business practices. The relevance of the topic is due to the fact that the strategic communications system is also a subject to qualitative changes brought about by new trends and patterns. If a fashion enterprise changes its principles, philosophy, ideology, and strategic priorities in the context of environmental transformations, customers should be made aware of these changes. Strategic communications and their transformations in the TFC industry remain largely understudied. The author identified the current working tools of the strategic communications system that could provide effective long-term development in the fashion industry. The research relied on the theory and methodology of strategizing developed by Professor V.L. Kvint, Dr.Sc.(Econ.), Foreign Member of the Russian Academy of Sciences. Such standard methods as analysis, synthesis, generalization, abstraction, and benchmarking made it possible to reveal the key strategic trends and patterns that shape the contemporary strategic principles of entrepreneurship in the TFC industry. The resulting updated system of strategic communications is effective in bringing across new values to fashion consumers.

Analysis of Local Bifurcations in One-Dimensional Systems

This article delves deeper into the study of local bifurcation in maps, although only in the context of a single dimension. The various local bifurcation types common to one-dimensional maps each have their own specific conditions that must be fulfilled. An object divides into two when it bifurcates. After a bifurcation, a family of one-parameter functions retains its stable or cyclic point structure. A bifurcation in the iterative process happens when a parameter is altered, causing a qualitative change in behavior. The phenomena of local splitting can be induced by adjusting just one parameter. Both the norm form of the transcritical split and the stability of the saddle node are highlighted. As with supercritical and subcritical bifurcations, the stability of the pitchfork bifurcation is assessed, as is its norm form.

Charged spinning fermionic configurations and a mass gap

We consider a self-consistent axially symmetric system supported by a classical nonlinear spinor field minimally coupled to electric and magnetic Maxwell fields. The presence of the nonlinearity of the spinor field ensures the existence of a minimum positive energy of the system (a mass gap), of a minimum charge (a charge gap), and of a minimum magnetic moment. In turn, the presence of the electric charge results in qualitative changes in the behavior of physical characteristics of the systems under consideration as compared with the case of an electrically neutral spinor field. It is shown that, with a suitable choice of free system parameters, there exists a regular finite-energy particlelike solution describing a localized spinning object whose physical parameters correspond to the main characteristics of an electron/positron (including the spin equal to 1/2), but with the characteristic size comparable to the corresponding Compton wavelength. Also, we show that four local Dirac equations are equivalent to two nonlocal equations.

A sustainable model of municipal economy

Sustainable development is a dynamic process based mainly on quantitative and qualitative changes in the economic, social and ecological spheres in accordance with the needs and preferences of the commune's inhabitants. Municipal management, however, creates favourable conditions for local development and constant improvement of the quality of life of residents. The aim of the study is to analyse municipal management from the perspective of sustainable development. The basic research method used in the study is indicator analysis. The indicators selected for development describe the concept of sustainable development in fundamental areas of the municipal economy, such as energy, water and sewage, waste, municipal housing, public transport and road infrastructure. The research was conducted in Poland in the Warmian-Masurian Voivodeship in 2020-2022. The subjects of the study are the 12 municipalities of the Olsztyn district. On the basis of the results obtained, it can be concluded that the best results in terms of creating a sustainable municipal economy are obtained by municipalities which have carried out the largest number of projects in this area, as well as those which have the largest share of forests and waters in the municipal area, e.g. Stawiguda, Dywity, Dobre Miasto, Gietrzwałd. The implementation of sustainable development in municipal management is determined by many economic, social, environmental, spatial and technological conditions. The research will enable local authorities and decision-makers to practically implement the concept of sustainable development in the municipal economy and may also be used in the process of planning investments and local activities, taking into account the economic, ecological and social aspects. The research constitutes the basis for further research work related to the practical implementation and management of sustainable development in municipal management.

Vibrations and energy distribution in inhomogeneous rods with elastic and viscous boundary conditions

Functionally graded materials have broad engineering applications including mechanical engineering, electronics, chemistry, and biomedical engineering. One notable advantage of such materials is that their stiffness distribution can be optimized to avoid stress concentration. A novel approach for solving the equations describing the longitudinal vibration of functionally graded rods with viscous and elastic boundary conditions is proposed. The characteristic equation of the system is derived for the solution of the undamped case for the constant stiffness rod. Then, a homotopy method is applied to compute the eigenvalues and mode shapes of graded rods for viscoelastic boundary conditions. The changes of the eigenvalues and mode shapes as function of the damping parameters are investigated. The optimal damping of the system is computed. It is shown that the qualitative behavior depends on the relation between the actual damping and the optimal damping of the system. The energy density distribution of graded rods is also discussed. An energy measure, the mean scaled energy density distribution is introduced to characterize the energy distribution along the rod in the asymptotic time limit. The significance of such a measure is that it reveals how the energy tends to distribute along the rod. It is shown that the energy distribution can be manipulated by changing the damping parameters. Qualitative changes depending on the relation between the actual damping and the optimal damping are highlighted.

Butyric Acid Supplementation Reduces Changes in the Taxonomic and Functional Composition of Gut Microbiota Caused by H. pylori Eradication Therapy.

Twenty two H. pylori-positive patients, aged 19 to 64 years, were enrolled in the study and randomized into two treatment groups, as follows: (1) ECAB-14 (n = 11), with esomeprazole 20 mg, clarithromycin 500 mg, amoxicillin 1000 mg, and bismuthate tripotassium dicitrate 240 mg, twice daily, per os, for 14 days, and (2), ECAB-Z-14 (n = 11), with esomeprazole 20 mg, clarithromycin 500 mg, amoxicillin 1000 mg, and bismuthate tripotassium dicitrate 240 mg, twice daily, along with butyric acid+inulin (Zacofalk), two tablets daily, each containing 250 mg of butyric acid, and 250 mg of inulin, per os, for 14 days. Fecal samples were collected from each subject prior to eradication therapy (time point I), after the end of eradication therapy (time point II), and a month after the end of eradication therapy (time point III). The total DNA from the fecal samples was isolated for whole genome sequencing using the Illumina NextSeq 500 platform. Qualitative and quantitative changes in gut microbiota were assessed, including alpha and beta diversity, functional potential and antibiotic resistance gene profiling. Gut microbiota alpha diversity significantly decreased compared with the baseline immediately after eradication therapy in both treatment groups (ECAB-14 and ECAB-Z-14). This diversity reached its baseline in the ECAB-Z-14 treatment group a month after the end of eradication therapy. However, in the ECAB-14 treatment arm, a reduction in the Shannon index was observed up to a month after the end of H. pylori eradication therapy. Fewer alterations in the gut microbiota functional potential were observed in the ECAB-Z-14 treatment group. The abundance of genes responsible for the metabolic pathway associated with butyrate production decreased only in the ECAB-14 treatment group. The prevalence of antibiotic-resistant genes in the gut microbiota increased significantly in both treatment groups by the end of treatment. However, more severe alterations were noted in the ECAB-14 treatment group. H. pylori eradication therapy leads to taxonomic changes, a reduction in the alpha diversity index, and alterations in the functional potential of the gut microbiota and gut resistome. Taking butyric acid+inulin supplements during H. pylori eradication therapy could help maintain the gut microbiota in its initial state and facilitate its recovery after H. pylori eradication.

Response evaluation criteria in PSMA PET/CT (RECIP 1.0) in metastatic castration-resistant prostate cancer.

45 Background: Response Evaluation Criteria in Prostate-Specific Membrane Antigen (PSMA) PET/CT (RECIP 1.0) initially integrated software-based quantitative assessment of PSMA-positive total tumor volume (PSMA-VOL). Clinical implementation of such software is not expected soon, limiting the use of RECIP in practice. This study aimed to assess the agreement of RECIP determined using tumor segmentation software (quantitative RECIP) with RECIP determined by qualitative reads by nuclear medicine physicians (visual RECIP) for response evaluation in metastatic castration-resistant prostate cancer. Methods: This multicenter retrospective study at three academic centers included patients who received lutetium-177 (177Lu) PSMA treatment between December 2014 and July 2019. PSMA PET/CT images at baseline and 12 weeks were assessed qualitatively by five nuclear medicine physicians for changes in PSMA-VOL and for new lesions. Quantitative changes in PSMA-VOL were also measured using tumor segmentation software. The status of new lesions was combined with qualitative changes in PSMA-VOL to determine visual RECIP and with quantitative changes in PSMA-VOL to determine quantitative RECIP. The primary outcomes were the agreement between visual and quantitative RECIP and the interreader reliability of visual RECIP according to the Fleiss κ. The secondary outcome was the association of visual RECIP with overall survival according to Cox regression. Results: A total of 124 patients (median age, 73 years [IQR, 67–76 years]) were included. Forty (32%) and 84 (68%) patients had quantitative RECIP progressive disease (PD) and non-PD, respectively. Agreement between visual versus quantitative RECIP was excellent (κ=0.89; 118 of 124 patients [95%]). Agreement among readers in classifying visual RECIP PD versus non-PD was excellent (κ=0.81; 103 of 124 patients [83%]). RECIP-PD was associated with significantly shorter overall survival compared with RECIP-nonPD (hazard ratio, 2.6 [95%CI: 1.7, 3.8]; P &lt;.001). Conclusions: Qualitatively assessed RECIP demonstrated excellent agreement with quantitative RECIP and excellent interreader reliability, and can be readily implemented in clinical practice for response evaluation in patients with metastatic castration-resistant prostate cancer undergoing 177Lu-PSMA therapy and possible other systemic therapies.

Impact of COVID-19 outbreak on subjective sleep during lockdown: relation with resilience characteristics.

The SARS-CoV-2 pandemic had a considerable impact on both the physical and mental health of people. Resilience is a psychological characteristic reflecting the ability to overcome or adapt to difficulties such as adversity, trauma, or extremely stressful situations. People with high resilience have been shown to exhibit lower levels of anxiety, stress and depression when faced with a stressful event. Sleep is particularly sensitive to anxiety and stress. The aim of this study was to investigate the impact of COVID-19 pandemic on sleep quantity, quality, and habits, while considering resilience as a factor. A total of 1260 individuals were recruited through an online survey. The variables that were assessed were socio-demographic, sleep habits and sleep disorders history, the Athens Insomnia Scale (AIS), the 25-item version of the Connor-Davidson Resilience Scale (CD-RISC), and any work/financial consequences during the first COVID-19 lockdown. The results showed that sleep habits during the lockdown changed for many of the participants. Their sleep schedule moving towards earlier or later for 9% and 67% of them, respectively; 38% of the participants were found to suffer from insomnia, based on the AIS score. A higher score on the CD-RISC was associated with better sleep. In conclusion, our study confirmed previous studies identifying quantitative and qualitative changes in sleep during the COVID-19 lockdown. It also expanded on the previous findings by identifying the correlation between sleep and resilience during the stressful period of the COVID-19 lockdown.

Multi-parametric optimization for controlling bifurcation structures

Bifurcations organize the dynamics of many natural and engineered systems. They induce qualitative and quantitative changes to a system’s dynamics, which can have catastrophic consequences if ignored during design. In this paper, we propose a general computational method to control the local bifurcations of dynamical systems by optimizing design parameters. We define an objective functional that enforces the appearance of local bifurcation points at targeted locations or even encourages their disappearance. The methodology is an efficient alternative to bifurcation tracking techniques capable of handling many design parameters ( &gt; 10 2 ). The method is demonstrated on a Duffing oscillator featuring a hardening cubic nonlinearity and an autonomous van der Pol-Duffing oscillator coupled to a nonlinear tuned vibration absorber. The finite-element model of a clamped-free Euler–Bernoulli beam, coupled with a reduced-order modelling technique, is also used to show the extension to the shape optimization of more complicated structures. Results demonstrate that several local bifurcations of various types can be handled simultaneously by the bifurcation control framework, with both parameter and state target values.
