Abstract

Introduction: Systemic inflammation plays a key role in the pathophysiology of acute coronary syndrome (ACS), having a direct effect in promoting the progression and rupture of vulnerable coronary plaques. The aim of this study was to investigate the association between inflammatory biomarkers and the type of ACS (ST-elevation myocardial infarction – STEMI, non-ST-elevation myocardial infarction – NSTEMI, or unstable angina – UA) in patients with confirmed heart failure.

Material and Methods: This study included a total of 266 patients admitted to the Clinical Department of Cardiology of the County Emergency Clinical Hospital of Târgu Mureș – Cardiac Intensive Care Unit (CICU) for ACS of various types (UA, NSTEMI or STEMI) between January 1, 2017 and December 31, 2020, in whom the diagnosis of heart failure was established based on clinical and paraclinical data. From the total number of patients, 36 were hospitalized for UA and 230 for MI, of which 165 were STEMI and 65 were NSTEMI.

Results: Only hs-CRP and IL-6 were significantly higher in MI compared to UA. Mean hs-CRP was 4.9 ± 4.5 mg/mL in patients with UA vs. 20.4 ± 42.2 mg/mL in patients with MI (p = 0.001), and mean IL-6 was 7.2 ± 13.8 pg/mL in UA vs. 31.6 ± 129.2 pg/mL in MI (p <0.0001). ICAM seems to have had a greater discriminating power between STEMI and other types of ACS in those with heart failure, having a value more than double in those with STEMI (216.1 ± 149.6 ng/mL vs. 448.2 ± 754.4 ng/mL, p <0.0001).

Conclusions: In patients with heart failure, the increase of inflammatory biomarkers such as hs-CRP is associated with the development of an acute myocardial infarction but not with its type. Adhesion molecules, especially ICAM, are elevated in patients with STEMI compared to other types of ACS, indicating a potential role of endothelial alteration in the development of an ACS when it adds to systemic inflammation linked to heart failure.

Abstract

Background: Monoclonal antibody therapy is currently an additional treatment option to reduce exacerbations and improve symptom control in patients with severe eosinophilic asthma (SEA) that is uncontrolled despite treatment with high-dose inhaled corticosteroids and long-acting beta-2 agonists. Benralizumab, a monoclonal antibody that binds to the interleukin-5 receptor (IL-5), significantly reduces symptoms and annual exacerbations, as well as the use of systemic corticosteroids in patients with SEA. However, few studies are available on the effectiveness of this biological treatment in real life. The aim of this case series was to evaluate the efficacy of benralizumab by analyzing changes in clinical parameters and blood eosinophils in patients with SEA.

Methods: We analyzed four patients with SEA who started treatment with benralizumab. The history of symptoms and exacerbations, eosinophil counts, data regarding the oral corticosteroid dose, need for rescue treatment, spirometry measurements and asthma control questionnaires (ACT) regarding the level of asthma control were recorded. A positive response to treatment was defined by a significant reduction in eosinophil counts, increased ACT scores, and lower rates of exacerbations.

Results and conclusions: Benralizumab monoclonal antibody was effective in all four patients. This was shown by a reduction in exacerbation rates, symptom severity, and lower dose of oral corticosteroids and rescue medication. This novel treatment was well tolerated by the analyzed patients, thus indicating that benralizumab is an attractive choice for patients due to eosinophilic count reduction as well as the less frequent dosing schedule. However, further studies are required, on larger populations.

Abstract
Oral dentures are subjected to mechanical and chemical cleansing processes. However, these processes alter the physical and mechanical properties of denture acrylic resins. This study analyzes the surface roughness of conventional heat-cured (HC) polymethacrylate, light-cured (LC) urethane dimethacrylate, and prepolymerized computer-aided design/computer-aided manufacturing (CAD/CAM) dental acrylic resins. The materials were subjected to combined surface treatment of mechanical brushing, thermal cycling, and immersion in chemical disinfectants (corega, chlorhexidine gluconate [CHG], and sodium hypochlorite) to simulate 1 year of clinical use. The surface roughness of the resin specimens before and after surface treatment was evaluated using a noncontact profilometer. Statistical tests based on analysis of variance revealed significant interactions between resin type and disinfectants, indicating that the effects of these two factors were interdependent. The highest and lowest surface roughness was observed in HC resins immersed in CHG and CAD/CAM resins immersed in sodium hypochlorite. Among the materials, HC resins demonstrated the overall highest mean roughness, followed by LC and CAD/CAM resins. Regarding the disinfectant use, the highest mean roughness was observed in disks immersed in CHG, followed by those immersed in corega and sodium hypochlorite. The prepolymerized CAD/CAM acrylic resin demonstrated superior surface quality following combined surface treatments. The HC and LC resins exceeded the roughness threshold and the reported roughness values for acrylic resins following surface treatments. Among the disinfectants tested, sodium hypochlorite produced overall low roughness values.
Rethinking Mass Communications in Norway
Authors: Bastiansen Henrik G. 
Published: October 2021

Abstract
The present article discusses the importance of the early years of mass communications in order to understand the shaping of them – the power of creating mass media for whole nations. It begins with references to scholars studying large nations and asks whether their results can be generalized to smaller countries. Therefore, it uses Norway as a case study. To what degree were Norway’s four major mass media – press, film, radio and television – formed institutionally in their early years? And if they were formed in this way, how long did the consequences of such a formation last? These questions have been neglected topics in research, so in order to answer them we also need to rethink the connections between the different media.
Ontology and the Mathematization of the Scientific Enterprise
Authors: Arenhart Décio Krause Jonas R. B. , da Costa Newton C. A. 
Published: October 2021

Abstract
In this basically expository paper we discuss the role oflogic and mathematics in researches concerning the ontology of scientific theories, and we consider the particular case of quantum mechanics. We argue that systems of logic in general, and classical logic in particular, may contribute substantially with the ontology of any theory that has this logic in its base. In the case of quantum mechanics, however, from the point of view of philosophical discussions conceming identity and individuality, those contributions may not be welcome for a specific interpretation, and an altemative system of logic perhaps could be used instead of a classical system. In this sense, we argue that the logic and ontology of a scientific theory may be seen as mutually inftuencing each other. On the one hand, logic contributes to shape the general features of the ontology of a theory; on the other hand, the theory also puts constraints on the possible understanding of ontology and, respectively, on possible systems of logic that may be the underlying logic ofthe theory.
Objects as Limits of Experience and the Notion of Horizon in Mathematical Theories
Authors: Livadas Stathis 
Published: October 2021

Abstract
The present work is an attempt to bring attention to the application of several key ideas of Husserl ‘s Krisis in the construction of certain mathematical theories that claim to be altemative nonstandard versions of the standard Zermelo-Fraenkel set theory. In general, these theories refute, at least semantically, the platonistic context of the Cantorian system and to one or the other degree are motivated by the notions of the lifeworld as the pregiven holistic field of experience and that of horizon as the boundary of human perceptions and the de facto constraint in reaching limit-idealizations. Moreover, 1 try to give convincing reasons for the existence of an ultimate constitutional ‘vacuum’ of a subjective origin that is formally refiected in the application of a notion of actual infinity in dealing generally with the mathematical infinite.
The Worldwood of the Cinematic Image
Authors: Martins José Manuel 
Published: October 2021

Abstract
A close analysis of the specifically cinematographic procedure in Akira Kurosawa’s ‘Dream’ Crows reveals it as an articulated and insightful philosophical statement, endowed with general relevance conceming ‘natural’ perception, phenomenological Erlebnis, mechanical image and aesthetic rapture. The antagonism between the Benjarninian lineage of a mechanical irreducibility of the cinematic image to anthropocentric categories, and the Cartesian tradition of a film-philosophy still relying on the equally irreducible structure of the intentional act, be it the one of a deeply embodied and enworlded counsciousness, in accounting for the essential structure of film and spectator (and their relation), i.e., the antagonism between the decentering primacy of the image and the self-centered primacy of perception, cannot be settled through a simple Phenomenological shift from occularcentric, intentional counsciousness to its embodyment ‘ in-the-world’ as yet another carrier of intentionality.
Still it remains to be explained what is it in the mechanical image that is able to so deeply affect the human flesh, and conversely, to what features in the human bodily experience is its mechanical other, the fascinating image, so successfuly adressing? It should be expected from the anti-Cartesianism of both the early and the late Merleau- Ponty the textual support for an approach to the essential condition of passivity in movie watching, that would be convergent with Benjamin. The Chapter ‘Le sentir’, in Phénoménologie de la perception, will offer us the proper guide to elucidate what we are already perceiving and conceiving in Kurosawa’s film, where the ex-static phenomenological body of the aesthetical contemplator ‘ enters the frame’ like the Benjaminian surgeon enters the body and like the painter - and always already like our deepest levei of ‘sensing’, previously to any act of cousciousness - ‘just looses himself in the scene before him’. The Polichinello secret of cinema watching is nonetheless too evident to be seen, and that is where Phenomenological description and reduction are still required.

Published: October 2021

Abstract
The influence of temperature and sulfuric acid concentration on the enthalpy and the rate of heat release during the reaction of Norwegian and Australian ilmenites with sulfuric acid was determined. The experimental results obtained from calorimetric measurements were compared with theoretical calculations based on the oxide composition and the phase composition of the raw material. Experimentally determined heat of reaction for Norwegian ilmenite (900–940 kJ/kg) and Australian ilmenite (800–840 kJ/kg) showed good agreement with theoretical calculations based on the phase composition of the raw material. It was found that the enthalpy of ilmenites decomposition reaction does not depend on the concentration of sulfuric acid in the concentration range from 83% to 93%. It was also demonstrated that the temperature and concentration of sulfuric acid have a significant impact on the thermokinetics of the decomposition process, increasing the value of the average rate of temperature change.

Authors: Valeš Roman , Dvořák Bohumír , Krupka Jiří 
Published: October 2021

Abstract
This work deals with a study of the effect of temperature on the cyclohexylamine disproportionation to dicyclohexylamine, conjointly with the thermodynamic analysis of this process. The laboratory experiments were carried out in a glass tubular continuous-flow reactor in a gaseous phase at the reaction temperature 433–463 K over a nickel catalyst. The results show, that the temperature has a trifling effect on equilibrium conversion of cyclohexylamine. However, temperature affects the formation of hydrocarbons, benzene and cyclohexane, and dehydrogenation products of dicyclohexylamine, i.e. N-cyclohexylidenecyclohexanamine and N-phenylcyclohexylamine. The latter one is the dominant product of dicyclohexylamine dehydrogenation. The disproportionation of cyclohexylamine has slightly exothermic character. At the experimental reaction temperature range, the cyclohexylamine disproportionation is spontaneous reaction and other reactions of this process are non-spontaneous.

Abstract
Lake ecosystems are important elements of hydrological regime, the quality of these ecosystems is affected by anthropogenic actions, and therefore, a variety of organisms, living in these habitats depend on the applied management solutions. Due to human activities freshwater ecosystems suffer from loss of biodiversity and increased eutrophication. Therefore, important aspects related to lake management include knowledge about the water quality, ecosystem response to climate change as well as increased risks of appearance and spreading of invasive species. Water quality, content of oxygen, nutrients, phytoplankton and distribution of macrophytes, including invasive species were analysed in Balvu and Pērkonu lakes. Presence of invasive species Canadian waterweed (Elodea canadensis) was detected, however, common reed (Phragmites australis) can be considered as expansive species. The analysis of current situation and existing management measures indicates persistent spreading of those species. Significant changes of lake water quality and climate may increase possible spreading of other, more aggressive, invasive species, for example – Nuttall’s waterweed (Elodea nuttallii).

Era globalisasi tidak hanya dapat memberi perubahan ke arah keberhasilan individu tetapi juga menyebabkan berkurangnya sikap nasionalisme, yaitu pengikisan identitas nasional bangsa. Budaya-budaya luar yang begitu mudah diserap oleh setiap masyarakat Indonesia, seperti gaya bahasa, fashion, perilaku, gaya berbicara, hingga pola pikir juga memberikan sumbangan terhadap nasionalisme tersebut. Penelitian ini bertujuan untuk mengembangkan alat ukur sikap nasionalisme. Ada tujuh aspek yang digunakan dalam menyusun skala sikap nasionalisme ini yaitu toleransi, tanggung jawab, rela berkorban, sopan santun, peduli terhadap sesama, bersedia menggunakan produk dalam negeri, dan mencintai budaya sendiri. Sebanyak 100 mahasiswa Universitas Malikussaleh, Aceh Utara dilibatkan dalam uji coba alat ukur ini. Hasil penelitian menunjukkan nilai reliabilitas yang tergolong tinggi yaitu 0.808. Dengan kata lain alat ukur sikap nasionalisme ini dapat dipercaya. Hasil analisis eksploratori yang dilakukan peneliti menghasilkan lima komponen penyusun sikap nasionalisme yang terdiri dari 38 item.
