description: Background and Aims: Cenicriviroc (CVC) is a C-C chemokine receptors type 2 and 5 dual antagonist under evaluation for treating liver fibrosis in adults with nonalcoholic steatohepatitis (NASH). Year 1 primary analysis of the 2-year CENTAUR study showed that CVC had an antifibrotic effect without impacting steatohepatitis. Herein, we report the final data from year 2 exploratory analyses. Approach and Results: This was a randomized, controlled study of adults with NASH, nonalcoholic fatty liver disease activity score ≥4, and NASH Clinical Research Network stage 1-3 fibrosis. Participants in arms A and C received CVC 150 mg or placebo, respectively, for 2 years; arm B received placebo in year 1 and switched to CVC in year 2. Liver biopsy was performed at baseline, year 1, and year 2. Of 289 randomized participants, 242 entered year 2. At year 2, 24% of patients who switched to CVC and 17% who remained on placebo achieved ≥1-stage fibrosis improvement and no worsening of NASH (P = 0.37). Twice the proportion on CVC who achieved fibrosis response at year 1 maintained benefit at year 2 (60% arm A versus 30% arm C), including 86% on CVC who had stage 3 fibrosis at baseline. Over 2 years, a similar proportion on CVC or placebo achieved ≥1-stage fibrosis improvement and no worsening of NASH (15% arm A versus 17% arm C). In patients with fibrosis responses, we observed consistent reductions in levels of N-terminal type 3 collagen propeptide and enhanced liver fibrosis scores, while increases in aspartate aminotransferase-to-platelet ratio index and Fibrosis-4 scores were consistently observed in nonresponders. Safety profile was comparable across groups. Conclusions: CVC was well tolerated, and year 2 data corroborate antifibrotic findings from year 1. The majority on CVC who achieved fibrosis response at year 1 maintained it at year 2, with greater effect in advanced fibrosis. ClinicalTrials.gov number, NCT02217475 (CENTAUR).

description: Aim: To assess the extent of gaps between root dentine and titanium or fibreglass post restorations following cementation with a self-adhesive resin cement. Methodology: Fourteen root filled maxillary central incisors restored with prefabricated posts made of Fibreglass (n = 7) or Titanium (n = 7) and cemented with RelyX Unicem 2 were imaged by rapid, high-resolution phase contrast-enhanced micro-CT (PCE-CT) in a synchrotron X-ray imaging facility (ID19, ESRF, 34 KeV, 0.65 µm pixel resolution). Reconstructions were used to measure canal, cement and post perimeters and cross-sectional areas and interfacial gaps at 0.1 mm increments in the root canal space, along the cervical region of the tooth. Remnants of endodontic sealer (AH Plus), when present, were also quantified. Mann–Whitney and 2-way ANOVA tests were used to compare findings within slices and between the two post groups. Pearson correlation coefficients (r) were determined between the interfacial gaps and the other measured parameters. Results: Clearly detectable gaps were found in 45% (±14%) of the interfaces between dentine and cement, along the canal in the cervical area of the tooth beneath the core. The length of interfacial gaps was moderately correlated to the canal cross-sectional area, to the canal perimeter and to the canal area filled by cement (R = 0.52 ~ 0.55, P < 0.001). There was no significant difference between samples with fibreglass or titanium (P > 0.01). Both post types had defect-free interfaces with cement. Endodontic sealer remnants were found on ~10% of the canal walls and were moderately correlated to the presence of gaps. Approximately 30% of the sealer-affected interfaces exhibited no detachment between dentine, sealer and cement. Conclusions: Self-adhesive cements had interfacial gaps along substantial regions of the root canal surface, which was not correlated with the amount of cement in the canal. PCE-CT proved to be an excellent non-destructive method to study root canal restorations of hydrated samples in 3D.

description: Bakalářská práce pojednává o vnímání vlastního života populací homosexuálně orientovaných mužů, kteří jsou nakažení virem HIV, žijí v Ústeckém kraji a jsou registrováni jako infikované osoby. Dále pak pojednává o jejich vnímání sociálních služeb v kraji a služeb sociální práce. Teoretická část se zaměřuje nejen na popis viru HIV a nemoci AIDS z obecné roviny, mechanismu fungování viru, léčby a dalších specifik onemocnění, ale také popisuje homosexualitu, její vznik a souvislost s virem a dále související pojem stigmatizace, neboť lze vyvodit, že virus sociálně stigmatizuje ty, kteří jím trpí. Empirická část si klade za cíl zjistit vnímání života gayů s HIV virem v Ústeckém kraji jejich očima. Formou polo-strukturovaných rozhovorů se proto zabývá jejich subjektivním hodnocením, názory a spokojeností z obecné životní roviny a dále také související otázkou stigmatizace.

description: We explore how the extraordinary properties of Rydberg atoms can be employed to impact the motion of ultracold ground state atoms. Specifically, we use an off-resonant two-photon laser dressing to map features of the Rydberg states on ground state atoms. It is demonstrated that the interplay between the spatially varying quantization axis of the considered Ioffe-Pritchard field and the fixed polarizations of the laser transitions provides the possibility of substantially manipulating the ground state trapping potential.

description: The circadian system is composed of coupled endogenous oscillators that allow living beings, including humans, to anticipate and adapt to daily changes in their environment. In mammals, circadian clocks form a hierarchically organized network with a 'master clock' located in the suprachiasmatic nucleus of the hypothalamus, which ensures entrainment of subsidiary oscillators to environmental cycles. Robust rhythmicity of body clocks is indispensable for temporally coordinating organ functions, and the disruption or misalignment of circadian rhythms caused for instance by modern lifestyle is strongly associated with various widespread diseases. This review aims to provide a comprehensive overview of our current knowledge about the molecular architecture and system-level organization of mammalian circadian oscillators. Furthermore, we discuss the regulatory roles of peripheral clocks for cell and organ physiology and their implication in the temporal coordination of metabolism in human health and disease. Finally, we summarize methods for assessing circadian rhythmicity in humans.
Il mondo di ieri e la terra del futuro. Ricordando Stefan Zweig, europeo, cosmopolita, pacifista

description: The article reviews the life and work of Stefan Zweig, playwright, journalist, biographer, historian and poet, born in Vienna on November 28, 1881, who committed suicide on February 22, 1942 in Petropolis, Brazil. Raised in Vienna, a cosmopolitan metropolis, in a Jewish family, as cosmopolitan as the city, assimilated into the culture of the Habsburg Empire – «a great and mighty empire» and «a world of security», Zweig experienced the collapse of what he calls «yesterday’s world», the European society, preceding World War that was perhaps more globalized than it is today. Perhaps nothing gives a better idea of the abyss the world has fallen into since World War I, writes Zweig, than the limitation on freedom of movement. Before 1914, everyone went where they wanted and stayed there as long as they wanted. «The world of security and creative reason in which we were born, where we grew up and where we felt like our own” was shattered “into a thousand pieces like an empty clay pot» by the World War one, then by the crises of the Twenties and Thirties, then by totalitarianisms. Escaping Nazism, Zweig becomes an exiled, taking refuge first in England, then in Latin America, in Brazil. There he discovers the world of the future, in this mixed Brazil which seems to ignore the tension and violence around the question of race that is destroying Europe. The Brazil that Zweig describes in his latest work, Brazil, Land von Zukunft, may be idealised. However, the enhancement of hybridisation was so foreign to the European thought at the time that one can only be grateful to Zweig for carrying the theme. The fascination with “the land of the future” couldn’t, however, console Zweig for the end of yesterday’s world. The writer could not survive Europe’s “suicide”.

description: There is a dearth of research on Holocaust survivors who immigrated to Brazil before, during, and after World War II. Also missing is a comprehensive analysis of how former Nazis escaped to the country after the War. This “co-existence” of Jewish survivors and Nazis within the same geographical location at the same time is a topic of great complexity, which I explore in this paper. In the first section of this paper, I will briefly address Brazil’s political history, while at the same time, its identity as an immigrant country, with a historically multi-ethnic cultural and demographic make-up, by analyzing the census data available. To explore how Jews negotiated their new position as survivors, immigrants, and members of a minority group who, while lived with the possibility of coexisting with war criminals, in section two, I analyze the memoirs of Aleksander Laks and Sabina Kustin, who, in different ways, transferred their fears from the old world to their new realities, due to imagined or real Nazi presence, which afflicted their existence and identity as Jews in Brazil. In the last section, I address the question of Nazi presence in Brazil. Using newspaper articles and governmental documentation, I highlight strategies used by war criminals such as Herbert Cukurs and Gustav Franz Wagner, to live freely in Brazil, and evade justice.

description: In resting-state functional connectivity experiments, a steady state (of consciousness) is commonly supposed. However, recent research has shown that the resting state is a rather dynamic than a steady state. In particular, changes of vigilance appear to play a prominent role. Accordingly, it is critical to assess the state of vigilance when conducting pharmacodynamic studies with resting-state functional magnetic resonance imaging (fMRI) using drugs that are known to affect vigilance such as (subanesthetic) ketamine. In this study, we sought to clarify whether the previously described ketamine-induced prefrontal decrease of functional connectivity is related to diminished vigilance as assessed by electroencephalography (EEG). We conducted a randomized, double-blind, placebo-controlled crossover study with subanesthetic S-Ketamine in N = 24 healthy, young subjects by simultaneous acquisition of resting-state fMRI and EEG data. We conducted seed-based default mode network functional connectivity and EEG power spectrum analyses. After ketamine administration, decreased functional connectivity was found in medial prefrontal cortex whereas increased connectivities were observed in intraparietal cortices. In EEG, a shift of energy to slow (delta, theta) and fast (gamma) wave frequencies was seen in the ketamine condition. Frontal connectivity is negatively related to EEG gamma and theta activity while a positive relationship is found for parietal connectivity and EEG delta power. Our results suggest a direct relationship between ketamine-induced functional connectivity changes and the concomitant decrease of vigilance in EEG. The observed functional changes after ketamine administration may serve as surrogate end points and provide a neurophysiological framework, for example, for the antidepressant action of ketamine (trial name: 29JN1556, EudraCT Number: 2009-012399-28).

description: Background and Aims: Zone-dependent differences in expression of metabolic enzymes along the portocentral axis of the acinus are a long-known feature of liver metabolism. A prominent example is the preferential localization of the enzyme, glutamine synthetase, in pericentral hepatocytes, where it converts potentially toxic ammonia to the valuable amino acid, glutamine. However, with the exception of a few key regulatory enzymes, a comprehensive and quantitative assessment of zonal differences in the abundance of metabolic enzymes and, much more important, an estimation of the associated functional differences between portal and central hepatocytes is missing thus far. Approach and Results: We addressed this problem by establishing a method for the separation of periportal and pericentral hepatocytes that yields sufficiently pure fractions of both cell populations. Quantitative shotgun proteomics identified hundreds of differentially expressed enzymes in the two cell populations. We used zone-specific proteomics data for scaling of the maximal activities to generate portal and central instantiations of a comprehensive kinetic model of central hepatic metabolism (Hepatokin1). Conclusions: The model simulations revealed significant portal-to-central differences in almost all metabolic pathways involving carbohydrates, fatty acids, amino acids, and detoxification.

description: During World War II, Mexico kept a selective and restrictive migratory politics towards the Jewish exile. Even though that politics was not singular in the region, it surprises that Mexico received only a group of 2,000 refugees. Despite this, Mexico became a permanent shelter for many refugees. The analysis focuses on the story of a survivor of the Holocaust -Bronislaw Zajbert- who was forced to move from his house in Lodz to be sent with his family to the ghetto of the city and emigrated first to Venezuela and later to Mexico. His experience swinging between the moving and the fixing contrasts the intensive mobility of those who managed to move in Europe to run away from Nazism. Their journey to Latin America emerges as a convergent experience while Mexico offered them in both cases the chance of finishing their displacement. It is an exploratory study that investigates how the individual experience of the transit impacted the construction of an affective and material home in Mexico.

description: The suitability of using a Nal crystal as a fast coincidence gamma ray detector was investigated using the multichannel "fast-slow" delayed coincidence method to obtain prompt time resolution curves with a Na²² gamma ray source at Nal temperatures of 170, 185, 200°K. A comparison of the time resolution curve obtained using two NE 102 plastic scintillators (FWHM: 640 psec) with that using a cooled Nal scintillator and a NE 102 scintillator (FWHM: 680-psee) showed that Nal is a satisfactory fast coincidence gamma ray detector at 185°K.
Analysis of doubly and triply ionised indium

Year: 2011

description: Emission spectra of Indium have been photographed over the spectral range from 340A° (177A° in 2nd order) to 9500A° using the disruptive electrodeless and spark in helium sources. About 4000 lines of Indium have been measured and 36% of these lines are classified as belonging to the spectra of InI,InII, Inlll, InlV and InV. The analyses of Inlll and InlV have been revised and extended to include 4d¹ºns(n=5 to 12), `4d¹ºns(n=5 to 9), 4d¹ºnd (n=5 to 9) and 4d¹ºnf(n=4 to 7). Polarisation theory has been applied to 4d¹ºng(n=5 to 9) and 4d¹ºnh (n=6 to 9) series and the ionization potential deduced from this is reported to be 226191.3 cm⁻¹. The dipole polarizability of the 4d¹º core is estimated to be 3.48a₀³ . Most of the expected terms of 4d⁹ 5s5p and 4d⁹ 5s6s are established for the first time. Some of the levels of 4d⁹ 5s5d are also added as well as some levels from the higher configurations 4d⁹ 5s7s and 4d⁹ 5s6d. In triply ionised Indium the new additions are to the 4d⁹5d, 4d⁹ 6d, 4d⁸5s and 4d⁹6p configurations. Houston's theory of intermediate coupling has been successfully applied to 4d⁹ns (n=5,6 and 7) terms. Tentative values are given to several levels of 4d⁸5s5p and 4d⁹4f terms. The double limit of InlV is calculated from 4d⁹ns series as 461875 cm⁻¹ and 468989 cm⁻¹. Experimental results are compared with the theoretical calculations for some of the configurations of Inlll and InlV.
Network analysis of the characters in A Game of Thrones: seeking for a predictive model of their death
Creators: name: Massari, Arcangelo
Publisher: name: Zenodo
Year: 2021

description: In the context of quantitative literary analysis studies, this research aims to verify the existence of a predictive model of characters' death in literary works. Using George R. R. Martin's book of A Game of Thrones as a model, the weighted degree, eigenvector centrality, betweenness centrality and local clustering coefficient for each node were calculated. After that, a monadic level test of logistic regression took place between these measures and the life and death condition of the characters at the end of the book. The outcome of the test did not lead to rejecting the null hypothesis, since no statistically significant relationship was found, but it did lead to interesting reflections on the work and poetics of George Martin, whose search for realism leads him intentionally to decree the death of his characters regardless of their centrality.

description: Following the coming to power of Hitler, in 1933, the Nuremberg Laws, in 1935, and the consequent annexing of Austria to Germany, in 1938, the situation of the Jewish community, in Europe, becomes desperate. This determined a wave of migration, towards the whole world. The Congress of Evian, convened by the President of the United States of America, Franklin D. Roosevelt, gathered delegations from 32 countries, in the purpose of identifying a solution for these Jewish refugees and a country willing to shelter them. The Congress of Evian concluded, in the general indifference of its representatives, with the only aid offer, by the Dominican Republic. This work provides an historical review of the events, before and after the Congress of Evian, as well as, an anthropological reflection on the older refugees’ and their descendants’ perspective, concerning their agricultural settlement in Sosúa, in the North of the Dominican Republic. This study also analyses the role of the dictator Rafael Leónidas Trujillo, in the negotiations, by the Dominican Republic, with the United States of America and the DORSA, which will finance the hosting plan for the Jewish refugees. This constitutes the backdrop of this scarcely known history, also light and shadows of the multiple reasons for the Dominican regime making this deal, although, this cannot be separated from the final paramount outcome of having saved lives.

description: Let $\mathcal{C}_1$ be the largest component of the Erdős--Rényi random graph $\mathcal{G}(n,p)$. The mixing time of random walk on $\mathcal {C}_1$ in the strictly supercritical regime, $p=c/n$ with fixed $c>1$, was shown to have order $\log^2n$ by Fountoulakis and Reed, and independently by Benjamini, Kozma and Wormald. In the critical window, $p=(1+\varepsilon)/n$ where $λ=\varepsilon^3n$ is bounded, Nachmias and Peres proved that the mixing time on $\mathcal{C}_1$ is of order $n$. However, it was unclear how to interpolate between these results, and estimate the mixing time as the giant component emerges from the critical window. Indeed, even the asymptotics of the diameter of $\mathcal{C}_1$ in this regime were only recently obtained by Riordan and Wormald, as well as the present authors and Kim. In this paper, we show that for $p=(1+\varepsilon)/n$ with $λ=\varepsilon^3n\to\infty$ and $λ=o(n)$, the mixing time on $\mathcal{C}_1$ is with high probability of order $(n/λ)\log^2λ$. In addition, we show that this is the order of the largest mixing time over all components, both in the slightly supercritical and in the slightly subcritical regime [i.e., $p=(1-\varepsilon)/n$ with $λ$ as above].

description: This study set to determine influence of family stability and peer group pressure ecological factors on risk taking behaviour among adolescents in secondary schools in Kajiado North SubCounty, Kajiado County. The area has numerous ecological factors that could influence the behaviour of adolescents. Since the area is home to a lot of the working population of the adjacent Nairobi City County, people from various backgrounds have immigrated there. As such, the values held by the inhabitants of the area are not easy to define. In this context, adolescents are prone to indulge in risky behaviours such as drug abuse, unprotected sex, and gang behaviour among others that could impact their lives negatively. This study adopted the Ecological Systems Theory. The study is also cross-sectional in nature. Data was collected from 267 students and 15 principals sampled using stratified proportionate sampling and total population sampling techniques. These were sampled from the 15 public secondary schools in Kajiado North Sub-County. Data from students was collected using questionnaires while the principals were interviewed. Pretesting of the questionnaires was undertaken to establish their reliability and validity. Descriptive and inferential statistics were used to analyse the data. Data from interviews was analysed thematically and the findings obtained used to verify those from students’ questionnaires. The findings obtained show that family stability and peer pressure influence risk-taking behaviour in adolescents. The study’s formulated hypotheses were tested at 95% confidence level using multiple regression analysis. The result showed that 3.7% (R2 = 0.037) variation in the level of risk taking behaviour was attributed to independent variables. The study recommends that family stability plays a crucial role in the risk-taking behaviour of students, it is important to ensure that cohesiveness in the families is encouraged. Teachers should be at the forefront for checking negative behaviours in schools so as to protect the spread of such behaviours among peers.
Specific heat and entropy of $N$-body nonextensive systems

description: We have studied finite $N$-body $D$-dimensional nonextensive ideal gases and harmonic oscillators, by using the maximum-entropy methods with the $q$- and normal averages ($q$: the entropic index). The validity range, specific heat and Tsallis entropy obtained by the two average methods are compared. Validity ranges of the $q$- and normal averages are $0 < q < q_U$ and $q > q_L$, respectively, where $q_U=1+(ηDN)^{-1}$, $q_L=1-(ηDN+1)^{-1}$ and $η=1/2$ ($η=1$) for ideal gases (harmonic oscillators). The energy and specific heat in the $q$- and normal averages coincide with those in the Boltzmann-Gibbs statistics, % independently of $q$, although this coincidence does not hold for the fluctuation of energy. The Tsallis entropy for $N |q-1| \gg 1$ obtained by the $q$-average is quite different from that derived by the normal average, despite a fairly good agreement of the two results for $|q-1 | \ll 1$. It has been pointed out that first-principles approaches previously proposed in the superstatistics yield $additive$ $N$-body entropy ($S^{(N)}= N S^{(1)}$) which is in contrast with the $nonadditive$ Tsallis entropy.

ON THE RELATION OF METAPHYSICS TO PHYSICS

Publisher: name: Zenodo
Year: 2023

description: Ignoring a crucial nuance in using the concept of metaphysics is "Does physics come first or metaphysics?" It makes it difficult to answer the question. The nuance under consideration is related to the "two-sided" structure of metaphysics. Metaphysics as a science refers to two types of phenomena with the existence of metaphysical principles - things that cannot be entered into concepts, closed to interpretation, and things that are realized through experience.

description: We present quantum theory of a membrane propagating in the vicinity of a time dependent orbifold singularity. The dynamics of a membrane, with the parameters space topology of a torus, winding uniformly around compact dimension of the embedding spacetime is mathematically equivalent to the dynamics of a closed string in a flat FRW spacetime. The construction of the physical Hilbert space of a membrane makes use of the kernel space of self-adjoint constraint operators. It is a subspace of the representation space of the constraints algebra. There exist non-trivial quantum states of a membrane evolving across the singularity.

description: Women experiencing perinatal mental-health illness have unique needs. The present study analyzes preliminary data about the effectiveness of MBDH in treating postpartum women with affective and anxiety disorders. We analysed 33 mothers with affective and/or anxiety disorders treated at the MBDH with their babies between March 2018 and December 2019. All women were assessed at admission, discharge and three months after discharge. Outcomes included symptoms of depression (EPDS) and anxiety (STAI-S), mother-infant bonding (PBQ) and functional impairment (HoNOs). We also assessed the clinical significance of changes in patients’ scores on these scales and patient satisfaction. At discharge, no patients still met the full criteria for the main diagnosis. Between admission and discharge, symptoms of depression and anxiety, mother-infant bonding, functional impairment and autonomy in caring for babies improved significantly. These gains were maintained at three months follow-up. Patient satisfaction was high. These preliminary results suggest that multidisciplinary intervention for postpartum women with affective or anxiety disorders at the MBDH improves maternal psychopathology, mother-infant bonding and mothers’ ability to care for their babies. MBDHs are a promising approach for delivering specialised perinatal mental-health care for mother-baby dyads.

On the interaction of low energy pions with nuclei
Creators: name: Scherk, Leonard Raymond
Publisher: name: University of British Columbia

description: The optical interaction of low energy( ≤30 MeV) pions with nuclei is discussed. In particular, it is shown that, since the nuclear density enters the low energy pion-nucleus interaction in a very direct manner, this interaction provides a sensitive means of investigating such properties of the nuclear density.as the diffuseness of the nuclear surface. A geometric discussion of the structure of the low energy pion-nucleus interaction is given which emphasizes the analogy between adding the scattered pion waves in the nuclear medium and adding electric potentials in a classical dielectric. The parameters of the optical potential which represents the interaction are taken to be those calculated by earlier authors who have used a multiple-scattering formalism to deduce the details of the-optical interaction from a microscopic point of view. The interaction is strongly momentum-dependent and the local part of the interaction is repulsive. It is shown that in optical scattering and absorption, the resonance aspects of the problem depend mainly only upon the height of the local potential barrier (~15 MeV) because of the long wavelength of the pion inside the nucleus. The optical absorption of low energy pions is shown to be sensitive to the diffuseness of the nuclear surface through the strong suppression of momentum-dependent absorption near the top of the potential barrier. It is argued that low energy pions can therefore be used to resolve the conflicts which presently exist in the information available from several experiments concerning the distribution of neutrons in the nuclear surface. The ideas developed in discussing the optical absorption of pions are extended to the excitation by pions of rotational states in strongly deformed nuclei. It is shown that, unlike the excitation cross sections obtained with more conventional interactions (such as the Coulomb interaction) , the excitation cross sections obtained from the pion-nucleus optical interaction depend strongly upon such characteristics of the nuclear density as its surface thickness. The rotational model of strongly deformed nuclei is assumed and an analysis of the excitation cross sections is made in the Distorted Wave Born Approximation. It is shown that the sensitivity to the nuclear surface thickness in the excitation cross sections arises from the suppression of the excitation processes due to the momentum-dependent interaction near the top of the potential barrier. It is suggested that the excitation of rotational levels in strongly deformed nuclei by pions can therefore be used to carefully examine the distribution of neutrons in the surfaces of strongly deformed nuclei.

description: We determine the axial, scalar and tensor isovector charges of the nucleon, sigma and cascade baryons as well as the difference between the up and down quark masses, mu−md. We employ gauge ensembles with Nf=2+1 nonperturbatively improved Wilson fermions at six values of the lattice spacing in the range a≈(0.039–0.098)  fm, generated by the coordinated lattice simulations (CLS) effort. The pion mass Mπ ranges from around 430 MeV down to a near physical value of 130 MeV and the linear spatial lattice extent L varies from 6.5M−1π to 3.0M−1π, where LMπ≥4 for the majority of the ensembles. This allows us to perform a controlled interpolation/extrapolation of the charges to the physical mass point in the infinite volume and continuum limit. Investigating SU(3) flavor symmetry, we find moderate symmetry breaking effects for the axial charges at the physical quark mass point, while no significant effects are found for the other charges within current uncertainties.
CHANGES IN LANGUAGE DUE TO NEW PHYSICS

Year: 2023

description: The purpose of this article is to show the expansion of language with the development of science. New theories introduced into physics caused very serious problems. Especially the so-called "new physics" of relativity and quantum theories forced us to search for a suitable scientific language to keep pace with the scientific reality that opened before us. The new physics damaged the deterministic mechanism. The scheme also changed the perception of language used by the scientific community. This situation, not only scientists, but also many people who use this language, felt the need to change the everyday language they use to describe scientific reality. In other words, this situation changed the types and fields of concepts used in physics along with the new physics.
