More aggressive reservoir conditions, such as higher concentrations of CO2 corrosive gases, have a massive effect on corrosion. Moreover, additional aqueous species, such as organic acids, have complicated the conditions and enhanced corrosion to the maximum rate. This study investigates and screens three commercial corrosion inhibitors on their performance in mitigating corrosion at welded areas of carbon steel in high CO2 conditions with the presence of organic acids. These investigations were conducted via chemical elucidations to study the functional groups present in the compounds that affect the inhibition performance and the electrochemical measurements to evaluate the inhibition activities and efficiency of these commercial inhibitors under extreme conditions of high CO2 and organic acids. The results indicated that only CT5727 and CT17906 gave a high inhibition efficiency of 90% in the absence and presence of organic acid, with CT5727 giving the lowest corrosion rate of 0.038 mmpy in the absence of organic acid, while CT17906 gave the lowest corrosion rate of 1.00 mmpy in organic acid condition. On the other hand, D4305 gave the worst inhibition performance under both conditions. The elucidation of these inhibitors also found that specific functional groups such as hydroxy, carboxylic acid, alkyl and alkene presence in the structure were believed to affect the inhibition performance of these commercial inhibitors in mitigating corrosion. These could be used as a future reference for the new development of corrosion inhibitors in similar conditions.

Aerospace industry is seeking thermoplastic composites materials due to several advantages over thermoset material and one of them is mechanical properties. Mechanical properties of thermoplastic composite materials are found to be superior compared to thermoset materials. High strength fibre composites parts are made of several plies with different fibre orientation with a designed balanced of lay-up sequence. Interlaminar Shear Strength (ILSS) is an essential consideration when designing laminated structures exposed to transverse stresses. It is to predict quality and strength of laminate levels of composite due to, composite failure cannot be observed directly to the propagation of single macroscopic crack when subjected to cyclic loading. This test is employed to evaluate both the interfacial adhesion of the matrix and the influence of the reinforcement on the mechanical characteristics of the composite. This study provides the understanding of ILSS test of 2 different thickness for 6 and 8 plies Carbon Fibre Reinforced Polyphenylene Sulfide (CF/PPS) according to the testing standard EN 2563. The results show that 8 plies have higher ILSS properties compared to 6 plies. The fractography of the CF/PPS composite under Scanning Electron Microscope (SEM) shows good agreement with the experimental values which was recorded 8 plies can withstand to shear strength of 79 MPa with maximum load applied was 2.738kN while, 6 plies recorded 75 MPa on shear strength with load of 1.971kN. More damage/cracks on 6 plies specimen compared to 8 plies.

Uniós polgárok kiutasítása más EU-tagállamból az Európai Bíróság legújabb gyakorlatában II.
Authors: Gyeney Laura
Published: March 2023

Aim: The aim of this study is to examine the direction in which the European Court of Justice can further develop its case law on expulsion decisions by Member State authorities in response to the new challenges facing European integration (including, in particular the practical difficulties arising from the completion of the Area of Freedom, Security and Justice and the divergent case law of the European Court of Justice).Methodology: Based on the most recent case law of the European Court of Justice, the study examines the areas in which it seems necessary for the Court to give interpretative decisions in the context of a prelimiray ruling procedure. The study is primarily based on actual (Member State) case law and its difficulties.Findings: The concept of a territorially united Europe is a necessary corollary to the completion of the Area of Freedom, Security and Justice. While the case law of the European Court of Justice on EU citizenship aims in many respects to strenghten this status (and, at the same time, to weaken Member States’ regulatory power) there is at least a partly opposite trend in the assessement of Member States’ expulsion policy under EU law. The study examines how the European Court of Justice can reconcile the federalising concept of EU citizenship with an expulsion policy based on sovereignity and the impact of all this on the unifying and expanding concept of EU citizenship.Value: The topic examined in the study has not been examined in the Hungarian literature before, the study is based on the latest case law of the European Court of Justice. The value of the study is that it attempts to identify the areas where the European Court of Justice may need to develop its case law in the near future to ensure the effective enforcement of EU law. The study can also provide guidance to domestic legislators and law enforcement agencies in this field.
Tiszta vizet Kelet-Afrika nyomornegyedeibe! A Magyar Máltai Szeretetszolgálat afrikai missziója

Published: March 2023

Aim: Researchers working on human security now know that all disciplines need to address the water issues of our planet, which is a major determinant of the sense of security of human life, because where there is no water, there is no life, and so there is no security. However, where there is water, but it is not of the right quality, i.e. it is not safe for biological organisms, it is still a threat. The absence of water, or its contamination can create a humanitarian crisis, a disaster or a natural disaster. The process of preventing, averting and remediating all these undesirable conditions is observed by the authors in the slums of three states in Central and Eastern Africa: Kenya, Uganda and Tanzania.Methodology: The authors have examined the historical and natural conditions of the African continent, the antecedents, possibilities and circumstances of the problem. They have explored a small body of international literature on the subject, interpreted the findings and assessments of academic literature and proposed solutions to the problem. The activities and methods of a Hungarian NGO in this field were examined.Findings: The authors of the study conclude that the African continent is facing many problems, that the slums are on the verge of a humanitarian and natural disaster, that the political systems of these states are unable or unwilling to deal with the problem, and that it is therefore necessary to call for the intervention of internal or external (international) NGOs to minimise the human cost of the humanitarian crisis.Value: It is made clear in the study that a Hungarian NGO has saved the lives of tens of thousands of children, women and elderly people in the African slums under study through its technical intervention. If public bodies cannot do it, NGOs can prevent, respond to and recover from humanitarian disasters.
International courts and atrocities in the XXI century
Authors: Pérez León Acevedo Juan Pablo
Published: March 2023

Mass atrocities perpetrated in the last years of the last century and those committed in the XXI century have received major attention from a wide arrange of actors. Indeed, these serious violations of human rights and international humanitarian law, which are constitutive of international crimes, have led to cases before supranational courts. The law and/or practice of international courts within their respective specific mandates demonstrate that there is an increasing international judicial engagement with rendering justice in scenarios of mass atrocities. In this context, the main research question addressed in this article is to identify some of the main contributions of international courts in mass atrocity cases in the XXI century. In this context, three supranational courts are taken into account: the International Court of Justice, the International Criminal Court, and the Inter-American Court of Human Rights.

NON-STATIONARY RESPONSE ANALYSIS OF A HIGH-RISE BUILDING IN HAIKOU DURING TYPHOONS
Authors: Hu Jiaxing , Li Zhengnong , Zhao Zhefei
Published: March 2023

From 2014 to 2016, several wind resistant field measurements were conducted to the high-rise building in Haikou. Based on these measurements, the present paper disclosed the characteristics of the time-history responses of axial acceleration on different floors during four typhoons, including the Rammasun, Kalmaegi, Mujigae and Sarika typhoons. The modal parameters of the measured building were identified by Morlet time-frequency wavelet transform methods, and the amplitude-dependent modal damping ratios and frequencies along translational directions were investigated. The results show that the variation trend of modal frequency with acceleration amplitude identified by the Morlet wavelet is the same as that recognized by time-domain method, while it is scattered with the interval bar (min-average-max) due to the nonstationary response of typhoon. Meanwhile, the larger the amplitude of acceleration response of high-rise buildings under strong wind, the greater the time-varying fluctuation of modal parameters identified by wavelet transform, and the bigger the difference between the interval bar (min-average-max). The full-scale study is expected to provide useful information on the wind-resistant design of high-rise buildings in typhoon-prone regions.

Recent observations have shown that the atmospheres of ultrahot Jupiters (UHJs) commonly possess temperature inversions, where the temperature increases with increasing altitude. Nonetheless, which opacity sources are responsible for the presence of these inversions remains largely observationally unconstrained. We used LBT/PEPSI to observe the atmosphere of the UHJ KELT-20 b in both transmission and emission in order to search for molecular agents which could be responsible for the temperature inversion. We validate our methodology by confirming a previous detection of Fe i in emission at 16.9σ. Our search for the inversion agents TiO, VO, FeH, and CaH results in non-detections. Using injection-recovery testing we set 4σ upper limits upon the volume mixing ratios for these constituents as low as ∼1 × 10−9 for TiO. For TiO, VO, and CaH, our limits are much lower than expectations from an equilibrium chemical model, while we cannot set constraining limits on FeH with our data. We thus rule out TiO and CaH as the source of the temperature inversion in KELT-20 b, and VO only if the line lists are sufficiently accurate.
Drift Performance and Chromatic Thermal Response of a Temperature Stabilized Solid-etalon Calibrator
Authors: Tang Liang , Hao Zhibo , Ye Huiqi , Zhai Yang , Zhang Kai , Xiao Dong
Published: March 2023

Etalon-based calibrators have rapidly gained popularity over the past decade in the field of high-precision radial velocity and high-resolution spectroscopy studies. Solid etalons are compact, pressure insensitive, commercially available alternatives to customized air spaced Fabry–Perot etalons. For tight-budget projects and weight-constricted missions, calibration system built from solid etalon is an interesting option to explore. For those, achievable spectral stability becomes the biggest question due to increased thermal sensitivity of the cavity material. Here, the design and performance of a low-cost solid-etalon calibrator is presented. A dual-loop temperature control system keeps the temperature fluctuations to within 1 mK rms when fully stabilized. Drift performance was tracked simultaneously with a laser frequency comb and the chromatic thermal response is measured through temperature tuning. The results indicate that a thermally controlled solid-etalon system can demonstrate sufficient short-term stability (<1 m s−1) for precise wavelength calibration in combination with a hollow-cathode lamp, and the measured drift and chromatic thermal response agree with theoretical predictions. Such systems are plausible candidates for cost-effective calibration of m s−1 level precision radial velocity instruments with improvement in thermal isolation, optimization in data processing, and long-term testing in the foreseeable future.
Accumulating Errors in Tests of General Relativity with Gravitational Waves: Overlapping Signals and Inaccurate Waveforms
Authors: Hu Qian , Veitch John
Published: March 2023

Observations of gravitational waves (GWs) from compact binary coalescences provide powerful tests of general relativity (GR), but systematic errors in data analysis could lead to incorrect scientific conclusions. This issue is especially serious in the third-generation GW detectors in which the signal-to-noise ratio (S/N) is high and the number of detections is large. In this work, we investigate the impacts of overlapping signals and inaccurate waveform models on tests of GR. We simulate mock catalogs for Einstein Telescope and Cosmic Explorer and perform parametric tests of GR using waveform models with different levels of inaccuracy. We find that the systematic error in non-GR parameter estimates could accumulate toward a false deviation from GR when combining results from multiple events, although a Bayesian model selection analysis may not favor a deviation. Waveform inaccuracies contribute most to the systematic errors, but multiple overlapping signals could magnify the effects of systematics owing to the incorrect removal of signals. We also point out that testing GR using selected “golden binaries” with high S/N is even more vulnerable to false deviations from GR. The problem of error accumulation is universal; we emphasize that it must be addressed to fully exploit the data from third-generation GW detectors and that further investigations, particularly in waveform accuracy, will be essential.

A selective evolutionary heterogeneous ensemble algorithm for classifying imbalanced data
Authors: An Xiaomeng , Xu Sen
Published: March 2023

Learning from imbalanced data is a challenging task, as with this type of data, most conventional supervised learning algorithms tend to favor the majority class, which has significantly more instances than the other classes. Ensemble learning is a robust solution for addressing the imbalanced classification problem. To construct a successful ensemble classifier, the diversity of base classifiers should receive specific attention. In this paper, we present a novel ensemble learning algorithm called Selective Evolutionary Heterogeneous Ensemble (SEHE), which produces diversity by two ways, as follows: 1) adopting multiple different sampling strategies to generate diverse training subsets and 2) training multiple heterogeneous base classifiers to construct an ensemble. In addition, considering that some low-quality base classifiers may pull down the performance of an ensemble and that it is difficult to estimate the potential of each base classifier directly, we profit from the idea of a selective ensemble to adaptively select base classifiers for constructing an ensemble. In particular, an evolutionary algorithm is adopted to conduct the procedure of adaptive selection in SEHE. The experimental results on 42 imbalanced data sets show that the SEHE is significantly superior to some state-of-the-art ensemble learning algorithms which are specifically designed for addressing the class imbalance problem, indicating its effectiveness and superiority.
Investigation of the dynamic response of subgrade vibration compaction based on the finite element method
Authors: Sun Hui , Yue Xiupeng , Wang Haining , Wang Liang , Li Yuexiang
Published: March 2023

A three-dimensional finite element model of a vibratory wheel on soil is established though the use of the ABAQUS software platform to investigate the interaction between the wheel and soil and the resulting dynamic response during vibratory compaction. The extended linear Drucker Prager model is used to reflect the plastic deformation characteristics of the soil. The truncated boundary is treated by using a three-dimensional uniform viscoelastic artificial boundary method. The vibratory responses of the soil under the wheel, including the stress and contact force, are analyzed by using numerical simulations. The results show a decrease in the soil vertical stress at the edge of the vibrating wheel transverse to the wheel path, which may assist in identifying the rolling overlap width of the wheel. Along the wheel path, the vertical stress center is demonstrated to lie ahead of the vibrating wheel mass center, caused by the inclination of the wheel soil contact surface. The contact pressure and total grounding width of the soil under the wheel can be calculated by using the finite element method; only one-third of the total width could produce effective compression deformation.
What do we need to know about neurosteroids and emotions?
Authors: di Michele Flavia , Romeo Elena
Published: March 2023

Neurosteroids are essential endogenous compounds which modulate numerous brain-related functions. Neurosteroids affect both the excitatory (glutamate) and the inhibitory (γ-aminobutyric acid, GABA) systems in the brain allowing for the modulation of a wide array of emotions and behaviors. Their synthesis is increased in response to stress, helping the organism to return to homeostasis. Alterations of neurosteroid concentrations therefore have a role in the pathophysiology of stress and stress-related conditions, such as mood (therefore acting on sadness and anger) and anxiety (fear) disorders. Here, we summarize the action of some neuroactive compounds, such as allopregnanolone, pregnanolone, pregnenolone, pregnenolone sulfate and dehydroepiandrosterone, in regulating emotions and outline their current pharmacological use in different pathologies.
On the spread of charitable behavior in a social network: a model based on game theory
Authors: Rocha A.C. , Monteiro L.H.A.
Published: March 2023

Many people worldwide depend on charitable donations to survive. Consider a social network engaged in charitable activities. Let this network be composed of individuals with heterogeneous donation behaviors: there are individuals that are influenced by the neighborhood activity and individuals that act by themselves. In this article, a model formulated in terms of a spatial iterated game is proposed to investigate the time evolution of the number of donors in this social network. In the proposed model, the population spatial structure is represented by a three-dimensional torus and the social interactions are represented by a payoff matrix. Here, the payoffs are a measure of the feeling of personal satisfaction for making (or not) a charitable contribution. Numerical simulations are performed in order to find out how the population size, the payoff for simultaneous donations, the probability of spontaneous donation, and the proportions of the distinct charitable behaviors affect the number of donors. The simulations reveal that an increase in the proportion of impure altruistic behavior improves the engagement in charitable projects if the donations motivated by pure altruism occur with low probability. The practical implications of this study can be especially relevant in times of economic crisis, like the one we are experiencing.
Factions in Nondemocracies: Theory and Evidence From the Chinese Communist Party
Authors: Francois Patrick , Trebbi Francesco , Xiao Kairong
Published: March 2023

This paper theoretically and empirically investigates factional arrangements within the Chinese Communist Party (CCP), the governing political party of the People's Republic of China. Using detailed biographical information of political elites in the Central Committee and provincial governments, we present a set of new empirical regularities within the CCP, including systematic patterns of cross‐factional balancing at different levels of the political hierarchy and substantial faction premia in promotions. We propose and estimate an organizational economic model to characterize factional politics within single‐party nondemocratic regimes and its economic implications.
Turing tests, catfishing, and other technologies of transgender rage
Authors: Publius Xavia Andromeda
Published: March 2023

This autoethnography traces Susan Stryker’s articulation of transgender rage through the monstrous cyborg figure of the catfish (people who pretend to be someone else online), examining the passing politics of the Turing Test and its trans foundations. The author’s disidentification with catfish characters in Glee, Pretty Little Liars, and Gossip Girl allows these characters to transmit and produce transgender rage, illustrating the strengths and weaknesses of taking a disidentificatory approach to transphobic texts.
Teaching trans studies through fan fiction in college English classrooms
Authors: Wu Peizhen
Published: March 2023

Trans studies has usually been taught within gender studies and women's studies programs. Yet, as trans studies has become highly interdisciplinary, trans awareness is still an issue in many fields; thus, incorporating trans discussions in courses in multiple disciplines is imperative. This study demonstrates how the firsthand teaching experience of a student-centered, literary-theory-related undergraduate course unit given by the English department incorporated trans studies through fan fiction. Particularly, we utilized the theoretical concept of nonbinary genders and its resistance to the heteronormative and heteropatriarchal system via a study of Loki's gender fluidity in the Loki miniseries, some exemplary transgender fan fiction, and the Omegaverse. Fandoms and fan fiction can be valuable course materials to create a comfortable space for students from different backgrounds to actively engage, discuss, and think critically about trans topics and trans theories. In this sense, this course unit explores the possibility of teaching trans studies beyond gender studies classrooms as well as courses focusing primarily on trans studies, encouraging more students to understand trans concepts and become trans allies.

Conservation of angular momentum and the existence of absolute time and space
Authors: Paglietti A.
Published: March 2023

The law of balance of angular momentum is shown to imply the existence of absolute time, a fundamental physical quantity that is independent of the motion or position of the observer. Absolute time implies the notion of absolute simultaneity, which in turn leads to the notion of absolute
distance between two points. The existence of absolute space follows as a consequence. These concepts apply to every field of physics to which the angular momentum balance law applies and, in particular, to the theory of special relativity. This paper also shows that in a vacuum, the independence
of the speed of light from the motion of its source makes it possible to determine the absolute positions of all points in space. The same independence also allows us to determine the state of absolute rest or motion of a reference frame from within the frame itself.
The role of the algebraic presign of the terms in the particles partition function
Authors: Arneth Borros
Published: March 2023

The algebraic sign of the first two terms of the novel partition function describing quantum chromodynamics and the standard model in particular, i.e., the sign of a and b, seems to play a decisive role in the calculation of the particle energies and masses. This role is discussed in
the following.
Double slit interference: Part I
Authors: Oldani Richard
Published: March 2023

Feynman referred to interference as “the only mystery,” and we continue to pursue that idea here by examining the theory behind it with heightened scrutiny. Three interpretations are described: The standard model, Feynman’s sum-over-paths, and Einstein’s
photon model. The standard model bases its arguments on the wave function and its subsequent collapse. The sum-over-paths model is equivalent to the standard model, but it explains interference by avoiding use of the wave function and its conceptual problems due to collapse. The Einstein model
is the most challenging for it is revolutionary and intuitively demanding. We critique the three models by studying their treatment of polarized light. In Part II, the interference of low intensity light will be discussed.
Testing a Planck scale mechanism by applying to matter a law for light: A new gravity theory that closely mimics standard theory
Authors: Kerr J. M.
Published: March 2023

The Planck scale is thought to be where space, time and matter as we know them begin, and seems to be vital to physics. Our ideas about that scale are unclear. String theory is dependent on supersymmetry, which unexpectedly has not been found—this leaves no reliable picture. In
some views the world is chaotic there, making it hard to explain the order at larger scales. Direct experiment cannot reach that scale, but indirect experiment and mathematics can. It would be wrong to assume, because of string theory, that only complex mathematics is relevant. This paper
is the second of three from a conceptual basis with a small group of simple but lateral assumptions about the structure of space, and the nature of light and matter. It leads to interpretations, in some areas to rederivations, in others to new mathematics that closely mimics existing physics.
Two spinoffs from the main theory are dimensional quantum mechanics [J. M. Kerr, Phys. Essays 33, 1 2019)], and here Planck scale gravity (PSG), in which a gravity mechanism reproduces Newtonian theory and parts of general relativity (GR). In a simple approach, the result is essentially
to test the idea that matter at a small scale is similar to light, as both are waves in the fabric of the dimensions, traveling in different directions through the structure of space, which takes the form of parallel cylinders. If one assumes matter travels at c around the circumference
of the cylinders, making loops at the Planck scale not unlike the closed string, one can apply to matter a law normally applied to light. What comes out is the mathematics of gravity, with what might be seen as “smoking gun evidence” (p. 11), showing that every point on any trajectory
through a gravitational field is connected to every other point on it. PSG is mathematically different from GR, but it mimics it across a range of physics, in most cases to eight decimal places. It is conceptually equivalent to GR in many areas including gravitational waves, and diverges in
a few places, leading to testable predictions.
Fundamentals of unified physics
Authors: Bacchieri Alfredo
Published: March 2023

This work is based on the following three premises: (1) Equality c = u with u = (‐2u)1/2 as the total escape speed (from all the masses in the universe) and u the total gravitational potential;
given a value of the universe mass, as shared by many physicists, u tends to c, hence constant on Earth. Moreover, the above equality implies the massiveness of light, which regards the second premise: (2) Structure of light: Longitudinal/sinusoidal particles, photons,
moving along rays, having parameters λ (their length) and frequency ν (their number, of the same ray, flowing in a time unit); now, if photons and electron should have, at their impact, opposite direction, a circling electron could fall into its nucleus, hence the third
premise. (3) A structure of the electron where its charge is not uniformly distributed, but it can be considered as a point particle fixed on the electron surface, facing the atom nucleus during the electron orbits; the electron charge corresponds to the photons-electron impact point, where
photons are absorbed and released. Due to these structures, the photons-electron impacts will force the involved electron to move, with a radial velocity w, toward wider orbits. On these bases, and according to the classical mechanics laws, we found, but not limited to, these results:
The measured speed of light, constant on Earth because of the equality #1, turns out to be also invariant whatever the relative motion observer-source (of light) is: In short, during the interaction photons-electron, due to both the electron radial velocity and its Doppler effect,
if the photons frequency decreases, then their length will increase (and vice versa) always inducing the invariant c. [The equality c = u has a cosmological reason: If c > u, all the visible masses, following the photons
mass moving toward the infinity, would be dispersed from each other; if c < u all masses would collapse, while, for c = u, the photons mass (as well as neutrinos mass, as shown) will ensure an endless balance between dispersion and collapse.] The
gravitational redshift and the claimed time dilation depend, like c, on the variation of the total potential. On H atom, the number of the electron circular orbits turns out to be n = 1, 2…137; the electron orbital speed along its ground-state
(g-s) orbit becomes v 1 = c/137, while the electron charge g-s orbital speed is v o = αc with α being the fine-structure constant. As for the claimed fall of circling electrons into their
nucleus due to their supposed photons emission, we found that the circling electrons are emitting the previously absorbed photons only during the spiral path from higher toward lower orbits; this emission avoids their fall. Then we show that the compensation velocity (to
restore the resonance source-detector located at different heights) has opposite direction with respect to the one predicted by relativity.
Active Learning Strategies in Higher Education in the Arab World
Authors: Abdelgwad Mohamed Hassan
Published: March 2023

Through this chapter there is reflection on using active learning strategies for agricultural education in the Arab world. There are difficulties with utilizing specific active learning strategies that encourage student learning and achieve important graduate attributes. Changing teacher and faculty perceptions about learning strategies and focusing on students' higher order thinking requires a lot of training, orientation, and mind shifting. Learning through specific active learning techniques, such as vocational, simulation, case studies, and using technology, supports student learning. It is particularly important to use instructional ways that encourage deep learning and analysis with agricultural problems and deficits. Professional development and hands-on learning changes perceptions of teachers through agricultural education in the Arab world. Many aspects relevant to using active learning in agricultural education perfectly in Arab world countries are clarified.
Establishing Career Advancement Centers in Egypt's Faculties of Agriculture for Human Resources Career Development
Authors: El-Shafie Emad
Published: March 2023

The agriculture sector is extremely important for Egypt's economy. For achieving food security objectives, within the SDGs 2030, the Agricultural Human Resources (AHRs) need systematic and regular training and lifelong learning. Faculties of agriculture (FAs) prepare and qualify researchers, technicians, and specialists in all areas of agriculture. Career advancement centers (CACs) need to be established in all FAs to provide lifelong opportunities to all AHRs' categories that need to cope with the ever advancing agricultural developments. To secure effective functioning of CACs, the different units needed, within their structures, are suggested. As a conclusion, establishing a CAC in each FA, is necessary and urgent for activating and maintaining its extension education, out-reach function of development, and serving the surrounding communities, especially rural communities. The currently working CACs need all types of support from the government, agri-business, and civil society organizations.
Crisis Resolution Through Insolvency Proceedings in Modern Times
Authors: Dubrovski Drago
Published: March 2023

Crises in business occur at different levels and in different dimensions, and often cannot be managed without the help of insolvency proceedings and insolvency law. Crisis management in these cases is extremely challenging and risky, although often the last way out of an acute crisis situation. The Slovenian normative regulation and the business and insolvency practices in place give companies that find themselves in an acute crisis and require the protection of the court a limited formal and practical opportunity to successfully manage (remedy) the resulting crisis and thus ensure their survival and further development, but the insolvency procedure alone cannot be successful if the other business conditions are not ensured to be fulfilled. Taking into account the theoretical findings and research results, the chapter additionally concludes that insolvency law in companies (creditors and debtors) is insufficiently known to managers, thus making it practically less useful in crisis resolution procedures.
