A Note on the Fixed Point Property of Non-metric Tree-Like Continua
Authors: Lončar Ivan 
Published: August 2024

The main purpose of this paper is to study the fixed point property of non-metric tree-like continua. It is proved, using the inverse systems method, that if $X$ is a non-metric tree-like continuum and if $h:X\rightarrow X$ is a periodic homeomorphism, then $h$ has the fixed point property (Theorem 2.4). Some theorems concerning the fixed point property of arc-like non-metric continua are also given.

An Example of a Globally Asymptotically Stable Anti-monotonic System of Rational Difference Equations in the Plane
Authors: Burgić Dževad , Nurkanović Zehra 
Published: August 2024

We consider the following system of rational difference equations in the plane: $$\left\{\begin{aligned}%{rcl}x_{n+1} &= \frac{\alpha_1}{A_1+B_1 x_n+ C_1y_n} \\[0.2cm]y_{n+1} &= \frac{\alpha_2}{A_2+B_2 x_n+ C_2y_n}\end{aligned}\right. \, , \quad n=0,1,2,\ldots $$ where the parameters $\alpha_1, \alpha_2, A_1, A_2, B_1, B_2, C_1, C_2$ are positive numbers and initial conditions $x_0$ and $y_0$ are nonnegative numbers. We prove that the unique positive equilibrium of this system is globally asymptotically stable. Also, we determine the rate of convergence of a solution that converges to the equilibrium $E=(\bar{x},\bar{y})$ of this systems.

A Partial Stratification of Secant Varieties of Veronese Varieties via Curvilinear Subschemes
Authors: Ballico Edoardo , Bernardi Alessandra 
Published: August 2024

We give a partial "quasi-stratification" of the secant varieties of the order $d$ Veronese variety $X_{m,d}$ of $\mathbb {P}^m$. It covers the set $\sigma _t(X_{m,d})^{\dagger}$ of all points lying on the linear span of curvilinear subschemes of $X_{m,d}$, but two "quasi-strata" may overlap. For low border rank two different "quasi-strata" are disjoint and we compute the symmetric rank of their elements. Our tool is the Hilbert schemes of curvilinear subschemes of Veronese varieties. To get a stratification we attach to each $P\in \sigma _t(X_{m,d})^{\dagger}$ the minimal label of a quasi-stratum containing it.

Glutathione tripeptide is a small thiol molecule, which protects the body from reactive oxygen forms, aging, exposure to xenobiotics, destructive inflammation, various forms of cell death, and many diseases that are the leading causes of mortality worldwide. Glutathione is found in all animal cells. It ensures optimal performance under the effect of various adverse environmental factors. The report gives an overview of the structure and synthesis of glutathione in the body, its key role in the formation of antioxidant protection, detoxification of exogenous and endogenous xenobiotics. We discuss the participation of the glutathione system in the innate and acquired immune response processes, programmed cell death, cell proliferation, DNA repair and synthesis. The article provides a list of factors that cause glutathione system depletion followed by a decrease in the reserve capacity of the cell, up to its death. The content of glutathione in food products and the possibility of its transport into the internal environment from food are discussed. Changes in the content of glutathione depending on the methods of its introduction into the body are considered. The objective was to provide the variety of physiological aspects of the role of glutathione, to give a complex impression of the importance of this molecule for the body, to demonstrate the significance and possibility of preventing depletion of the glutathione system.

AIM OF THE STUDY: The purpose of the present study was to evaluate demographic characteristics of inmates in the Canton of Zurich (exposure), and investigate the changes in diseases and drug use between 2015 and 2020 (outcome).
METHODS: The study prospectively evaluated 51,989 inmates admitted to the Police Prison Zurich in Switzerland between 1 April 2015 and 31 August 2020 and who were systematically medically assessed. A total of 19,027 (37%) inmates had one or more health conditions, which the authors recorded according to the International Classification of Diseases-10 (ICD-10), in addition to demographic data (country of origin, sex, age, year of imprisonment), as well as details of any drugs used (type and dosage).
RESULTS: The 19,027 inmates with medical conditions had a mean age of 35.4±12.5 years (range 10–89) and comprised 16,489 males (87%). The inmates originated from 170 countries, including 4606 from Switzerland (24.2%), 4227 from Eastern Europe (22%) and 3432 from the Middle East & North Africa (18%). A total of 1631 inmates (9%) were enrolled in the medication-assisted treatment (MAT) programme, and 672 patients (4%) received a psychiatric evaluation. The proportions of foreign prisoners did not increase during the study period. There was a significant increase in the use of antipsychotics from year 1 to 5 (y = 0.866x; R2 = 0.902; p = 0.01) and anticonvulsants from year 1 to 4 (y = 1.27x; R2 = 0.823; p = 0.01), and a significant decrease in the use of analgesics from year 2 to 5 (y = -4.42x; R2 = 0.947; p = 0.03) and antianxiety drugs from year 1 to 4 (y = -3.31x; R2 = 0.989; p = 0.005). Inmates from Switzerland were most likely to use antianxiety drugs, while inmates from the Middle East & North Africa were most likely to use antipsychotics (OR 2.09; CI 1.88–2.34) and anticonvulsants (OR 3.52; CI 2.90–4.29), whereas inmates from Latin and North America were most likely to use herbal medicine (OR 1.50; CI 1.05–2.10).
CONCLUSIONS: The findings of this study could help anticipate needs of prisons as well as improve treatment of disease and assist with substance use or abuse, particularly in the context of migration.

Morfología de las especies invasoras Carpobrotus edulis y Carpobrotus acinaciformis y su propagación en el noroeste de España
Authors: Pasantes Campaña Mateo 
Published: August 2024

Morphologically differentiating closely related species can be difficult. The genus Carpobrotus, which includes numerous globally distributed species, presents thischallenge. In northwest Spain, several studies identify only one species, Carpobrotusedulis. However, in this work two species have been differentiated in the region and clearguidelines for their identification are provided.In addition, an exhaustive analysis is carried out on the expansion of these species overthe years in the area, offering detailed visual information on the advance of these invasiveplants. This analysis not only allows us to better understand the dynamics of the invasion, but also to develop more effective management and control strategies. The combination of precise identification and temporal monitoring of the distribution of Carpobrotus sp. in the northwest of Spain constitutes a crucial tool for the management of these invasive species and the protection of local biodiversity.
Post-Imperial Bacchus: The politics of literacy criticism in Camões studies 1940-2001
Authors: Alves Hélio J. S. 
Published: August 2024

Abstract: A post-imperial approach to Camões cannot ignore the figure of Bacchus. As Camões’s very epic might suggest, Bacchus strongly tends to constitute a non-subject for both “imperial” and “liberal” critics. Given that context, one ought to denounce the politics of criticism apparently sustained by reliable philological practice and show how they silence or put aside a presence that, also through philology, cannot but dominate the meaning of Os Lusíadas.
Africa and the Epic Imagination of Camões
Authors: Blackmore Josiah 
Published: August 2024

Abstract: This article advances arguments about the metaphoric presence of Africa primarily in the ideology of Os Lusíadas (the episode of Adamastor) and secondarily in the chronicles of Gomes Eanes de Zurara. It proposes that Adamastor is a figure of Renaissance melancholy (in both somatic and prophetic terms) and, as such, represents a melding of interior and exterior forms of consciousness or knowledge. Africa and the Moor function in Camões as an index of the “strange,” a principle of Camonian epic in which the foreign and the alien are repeatedly inscribed into expansionist thought and therefore are an integral component to it. Zurara's chronicles establish Africa as a primordial space of imperialism and its attendant historiographic discourse under the sign of Saturn, planet of time and melancholics.
Second Attempt
Authors: Tamen Miguel 
Published: August 2024

Abstract: In his well-known, and often very loose, paraphrase of Psalm 137, Camões suggests that he has “hung on the willow trees / The organs with which I had sung” (11.54-55). This looks prima facie false, since he has already produced at least 53 lines after that event, and will go on to produce many more, to the total of 365. What is the status of a poetic composition that purports to escape the pitfalls of poetry, and, more to the point, what is the use of poetry if not that of perpetuating itself through elaborate excuses for its own emergence?
Bridging the Broadband Gap: Leveraging Public-Private Partnerships to Level Out Internet Inequality
Authors: Wu Zachary 
Published: August 2024

As a result of huge fixed costs to enter the Internet market, providers of reliable broadband connections are often overly hesitant to expand their service to rural areas. Over the past decade, the chasmic separation between those who have high-speed connections and those who do not has only widened, leading to economic inequality. Without access to broadband, millions of Americans are left unable to participate in the economy, which is now more digital than ever. Internet resources are becoming increasingly critical in telework, job searching, education, and more. As such, it is particularly damning when a large subsection of the population faces severe limitations in the quality of their Internet service. Although many solutions have been explored by the government, most have failed to deliver long-lasting improvements to the broadband gap. This paper argues that in order for broadband infrastructure expansion to be effective, the optimal policy solution must harness the strengths of both public and private stakeholders in unison. Whereas private actors like Internet providers have little to no organic incentives to build cables in untapped markets where there is no sufficient guarantee of return, and government actors like federal agencies cannot directly finance these projects for fear of exposing taxpayers to risk, neither privatization nor government intervention is normatively preferable. Rather, when governments and private firms share the responsibility, and by extension, the associated risks, of broadband projects, this framework of public-private partnership offers the most potent solution to status quo inequities.
