Published: November 2023

Recently, fiber-metal laminates have gained high attention from material scientists and engineers, particularly when it comes to impact-critical applications. When compared to metallic alloys and composite materials, fiber-metal laminates offer several distinguishing advantages. This work intends to evaluate the low-velocity response of kenaf fiber-reinforced polypropylene metal-composite laminates with various fiber compositions, in line with the current trend of using natural fiber as possible reinforcement in composite materials. In addition, a comparison was made between the low-velocity impact response of non-treated and chemical-treated kenaf fiber-reinforced composite-metal laminates. A hot molding compression technique was employed to fabricate the laminates. Low-velocity impact tests were performed based on ASTM D7136 to determine the peak force, maximum displacement, and energy absorption of the materials. The results confirmed that NaOH treatment and increased fiber content resulted in a higher peak force of NaOH-treated kenaf-based metal laminates. For NaOH-treated laminates, the peak force of laminates with 70 wt% was found to be 11.20% higher than laminates with 50 wt% at the impact energy of 60 J. At fiber content of 70 wt%, the peak force of NaOH-treated laminates is 2.14% greater than that of untreated laminates when subjected to low-velocity impact with an energy level of 60 J. However, laminates with low fiber content and without NaOH treatment manifested higher maximum displacement and energy absorption due to the ductile behavior of such materials.
Democratizing dual enrollment: Beyond economic rationales
Authors: Duncheon Julia C. , Hornbeck Dustin
Published: November 2023

Dual enrollment (DE) is a popular reform in the United States that allows high school students to take college courses through partnerships between school districts and institutions of higher education. DE programs have been scaling rapidly, but participation is stratified by race and class, and research reveals little about the quality and content of DE courses. These limitations stem, in part, from a lack of theorizing around what purpose DE reform can and should serve, both in the lives of youth and for communities writ large. Situated in literature on the purpose of education in capitalist democracies, this study employs qualitative content analysis to examine the rationales for DE coursework, as depicted in state-level policy documents. Findings indicate that DE policy rationales are depicted almost entirely in neoliberal economic terms. We argue that, while economic benefits are important, the almost exclusive emphasis on economic outcomes has led to rapid scaling of a curricular reform with insufficient attention to teaching, learning, and equity. To maximize the potential benefits of DE reform, we call for imagining its democratic possibilities.
Strategi Pemagaran dalam Ujaran Bahasa Jepang: Analisis Wawancara Jalanan Kanal Youtube Ask Japanese

Published: November 2023

This study reviews the hedging phenomena in Japanese speech found in street interview Ask Japanese. The hedging can be seen in interviewees’ answers to the interviewer’s questions. The data source used in this study is videos uploaded to Youtube by channel Ask Japanese. The reason for choosing such data source is that the videos are recorded impromptu, and thus, they show the realization of hedging in utterance naturally without any make-up. There are, in total, two videos of interview that is analyzed. The theories used are hedging as semantic phenomenon and hedging as pragmatic phenomenon. This research employs qualitative method that is involving analyzing data that have been transcribed and codified beforehand. In the videos used, there are 234 cases of hedging found. After keen observation, it is revealed that those cases of hedging are not realized in the same way. They can be classified into 6 types of strategies according to their realization in speech, namely (i) hedging by emphasizing subjectivity, (ii) hedging by expressing uncertainty, (iii) hedging by creating common ground, (iv) hedging by approximation, (v) hedging by exemplification, and (vi) hedging by downtoning.

Authors: Stabentheiner Edith , Gross Andrea , Soja Gerhard , Grill Dieter
Published: November 2023

The ozone sensitive tobacco cultivar Be!W3 (Nicotiana tabacum L.) was used to monitor ozone pollution for one vegetation period (beginning of May till end of September) in Graz, a city of approximately 240 000 inhabitants in the south of Austria. The plants were exposed for 14 days in standardized shaded exposition racks. The insensitive tobacco cultivar BelB was used as a control. The leaf necroses characteristic for ozone damage were well correlated with ozone dose (AOT 40) with the exception of the first exposition period in May. The reliability of the evaluation of visible symptoms on tobacco leaves was confirmed by computer­ aided image analysis. It was possible to identify the spatial and temporal ozone distribution within a project area.
The multifunctional LBC-Corpora: different aims depending on the user
Authors: Flinz Carolina
Published: November 2023

Corpora are nowadays the primary source of many dictionaries and the core element of various platforms and information systems. Lexicographers have therefore a variety of new possibilities which were unthinkable in the past with different types of corpora available for use in the data collection phase of the lexicographic process (Flinz 2021). Not only lexicographers, but also other types of users (academics, translators, teachers, students etc.) can profit from them, especially when corpora are public and can be accessed using corpus linguistic tools (Ballestracci/Buffagni/Flinz 2020; Flinz/Farina 2020). The LBC-corpora are monolingual specialized comparable corpora, already online (http://corpora.lessicobeniculturali.net/) and, as monitor corpora (Lemnitzer/Zinsmeister 2015: 140), they will be augmented over time. They can be analysed using the open source tool NoSketchEngine (Billero 2020). The LBC-Corpora are also the lexicographic primary source of the LBC multilingual dictionary, which is in preparation: the provisional entry lists of different languages (Spanish, German, and French) are now ready (Billero/Farina/Nicolás Martínez 2020) and together with a selection of KWICS, which have been carefully selected following a quantitative-qualitative procedure (for German see Buffagni/Flinz/Ballestracci in prep.), will soon be online (Flinz et al. in prep.). The purpose of this paper is to reflect on the LBC-corpora from a double perspective: from the user of the LBC-platform and from the lexicographic team. In the first case following an overview of the principal characteristics of the LBC-Platform, the focus will be on the accessible corpora showing the tools which can be used (§ 2). In the second case the LBC-corpora will be examined in their function as a data basis for the LBC-Dictionary (§ 3). The attention will be on the data preparation phase: after discussing the procedure for the realization of the LBC-provisional lemma candidate lists, the focus will be on the adopted procedure for finding equivalence relations and for the individuation of other types of relations between the entries (synonymy, belonging to the same semantic field etc.). In § 4 the focus will be on the LBC-provisional lemma candidate lists and their related KWICs. Conclusions and an outlook to the future can be found in the last section (§ 5).
A novel way of extracting full-fledged terminologies from multilingual texts
Authors: Gromann Dagmar , Heinisch Barbara , Wachowiak Lennart , Lang Christian
Published: November 2023

Terminology as a term refers to terminology science and simultaneously to practically curated terminological resources (TR). The latter fall within the scope of language resources. Manually curating such a TR is labor- and time-intensive. Thus, it has been a long-standing research endeavor to reduce this effort by automating the TR creation process. However, to this point such endeavors have focused on terms rather than on interrelations. Instead of directly interrelating terms, they are conventionally grouped by synonymy and equivalence into concepts, and relations are established between concepts. This paper introduces preliminaries of terminology science and practice, common models of interrelating terminological concepts, and especially focuses on a new way to define terminological relations and a system to extract terminological information from texts across domains and languages by means of recent neural methods.
Anonymity and Online Search: Measuring the Privacy Impact Of Google’s 2012 Privacy Policy Change
Authors: Cooper James C.
Published: November 2023

One of the most vexing problems in privacy policy is identifying consumer harm from unwanted observation; because it is highly subjective and is likely to vary greatly throughout the population, it doesn’t lend itself to easy measurement. Yet, these types of situations increasingly are the focal point of privacy policy discussions, including the Supreme Court’s recent decisions regarding standing and the FTC’s recently announced commercial surveillance rulemaking. The primary approach to attempt to quantify subjective harms has been to measure consumers’ willingness to exchange personal data for money in an experimental setting. This study takes a different tack, using field data to measure actual consumer response to a real-world reduction in the anonymity of online search. In March 2012, Google began to combine user information across platforms. To the extent that Google’s policy change reduced the anonymity associated with Google search, it may have diminished incentives to search sensitive topics. Using Google Trends (GT) data and a difference-in-difference estimator with top non-sensitive search terms as the control group, the results suggest that there was a 3–7 % short-term (1–2 months) reduction in sensitive search (relative to the non-sensitive search control group), as measured by GT. I examine heterogenous treatment effects, and find that the largest measured impact is for health-related search. There is no measured difference in reaction between high- and low-privacy demand states.
Hubert Treiber and the
Sociology of Law
of Max Weber: From the Ideal Types of Legal Rationality to the Plurality of Law
Authors: Coutu Michel
Published: November 2023

Hubert Treiber has established himself as one of the world’s leading scholars of Weber, in particular of his Sociology of Law. Especially, Treiber defends Weber’s decisive contribution to legal pluralism, comparable to Eugen Ehrlich’s, although from a quite different perspective. Indeed, it is not possible to analyse Weber’s distinction between state and non-state law (a central distinction for legal pluralism) without taking into consideration what he means, sociologically, by “law” on the one hand and by “the state” on the other. Weber’s ideal typical construction of social relations under the category “law” requires an Archimedean point, which is the formal rationality of law, closely associated, at the end of an historical development, with the efforts of legal abstraction and systematisation by the proponents of Pandectism in modern Germany. In the following text, linked to some of Treiber’s major works, the author addresses first Weber’s analysis of the rationalities of law, and then deals with the question of the plurality of law, as these two aspects are closely intertwined.
RZZ‐Spindly and CENP‐E form an integrated platform to recruit dynein to the kinetochore corona
Authors: Cmentowski Verena , Ciossani Giuseppe , d'Amico Ennio , Wohlgemuth Sabine , Owa Mikito , Dynlacht Brian , Musacchio Andrea
Published: November 2023

Chromosome biorientation on the mitotic spindle is prerequisite to errorless genome inheritance. CENP‐E (kinesin‐7) and dynein–dynactin (DD), microtubule motors with opposite polarity, promote biorientation from the kinetochore corona, a polymeric structure whose assembly requires MPS1 kinase. The corona's building block consists of ROD, Zwilch, ZW10, and the DD adaptor Spindly (RZZS). How CENP‐E and DD are scaffolded and mutually coordinated in the corona remains unclear. Here, we show that when corona assembly is prevented through MPS1 inhibition, CENP‐E is absolutely required to retain RZZS at kinetochores. An RZZS phosphomimetic mutant bypasses this requirement, demonstrating the existence of a second receptor for polymeric RZZS. With active MPS1, CENP‐E is dispensable for corona expansion, but strictly required for physiological kinetochore accumulation of DD. Thus, we identify the corona as an integrated scaffold where CENP‐E kinesin controls DD kinetochore loading for coordinated bidirectional transport of chromosome cargo.

The accumulation of misfolded and aggregated proteins is a hallmark of neurodegenerative proteinopathies. Although multiple genetic loci have been associated with specific neurodegenerative diseases (NDs), molecular mechanisms that may have a broader relevance for most or all proteinopathies remain poorly resolved. In this study, we developed a multi‐layered network expansion (MLnet) model to predict protein modifiers that are common to a group of diseases and, therefore, may have broader pathophysiological relevance for that group. When applied to the four NDs Alzheimer's disease (AD), Huntington's disease, and spinocerebellar ataxia types 1 and 3, we predicted multiple members of the insulin pathway, including PDK1, Akt1, InR, and sgg (GSK‐3β), as common modifiers. We validated these modifiers with the help of four Drosophila ND models. Further evaluation of Akt1 in human cell‐based ND models revealed that activation of Akt1 signaling by the small molecule SC79 increased cell viability in all models. Moreover, treatment of AD model mice with SC79 enhanced their long‐term memory and ameliorated dysregulated anxiety levels, which are commonly affected in AD patients. These findings validate MLnet as a valuable tool to uncover molecular pathways and proteins involved in the pathophysiology of entire disease groups and identify potential therapeutic targets that have relevance across disease boundaries. MLnet can be used for any group of diseases and is available as a web tool at http://ssbio.cau.ac.kr/software/mlnet.

Published: November 2023

This study aimed to investigate the role of mitochondrial-related protein Mfn2 in polycystic ovary syndrome (PCOS) and its impact on oocyte development. The pathological features of PCOS model mice were confirmed by hematoxylin–eosin staining and immunohistochemistry. The expression of Mfn2 and mitochondrial-related proteins in PCOS oocytes and granulosa cells was detected by qRT-PCR and Western blot. Mitochondrial quantity was measured by Mito-Tracker staining, and the structure of mitochondria-associated ER membranes (MAMs) was observed by transmission electron microscopy. The results showed that Mfn2 was significantly downregulated in PCOS oocytes and granulosa cells, and its expression was inhibited in oocytes at different developmental stages. Moreover, the structure of MAMs was also disrupted. Downregulation of Mfn2 expression led to a reduction in mitochondrial quantity in oocytes and granulosa cells, as well as disruption of MAM structure, while overexpression of Mfn2 had the opposite effect. In conclusion, this study indicates that Mfn2 affects the development of PCOS oocytes by regulating MAMs and may be involved in maintaining the stability of MAM structure and function, thereby affecting mitochondrial quantity and function. These findings provide new insights into the pathogenesis and treatment of PCOS.
Influence of temperature regimes of synthesis on the structure of glassy GeS2
Authors: Rosola I.J. , Tsyhyka V.V. , Tsyhyka M.V.
Published: November 2023

The effect of synthesis temperature regimes on the structure and some physical properties of glassy germanium disulfide was examined using the methods of dilatometry and Raman scattering of light. It is concluded that the bond angle disorder increases and the formation of stronger Ge–S bonds in the tetrahedral structure depends on the increase in the synthesis temperature of glassy GeS2. Significant changes in the structural grid of glass also occur when the thermal history of the sample varies in the temperature interval of vitrification.

Authors: Njim E.K. , Sadiq S.E. , Tahir M.S. Al-Din , Flayyih M.A. , Hadji L.
Published: November 2023

This work synthesized a thermoplastic polymer with varying densities along one direction using additive manufacturing technology to study the dynamic and static characteristics of functionally graded viscoelastic materials (FGVMs). To describe the mechanical properties of FGVMs, an analytical formulation based on the sigmoid-law formulation was proposed. The experimental program is conducted on 3D-printed samples, and various tests are conducted to examine the performance of such materials. Furthermore, the finite element method was used to evaluate the structural system's flexural properties. The influences of FG parameters and geometrical properties on flexural and reverse bending fatigue life are analyzed. The results show that increasing porosity from 10% to 30% at a power-law index (k = 2) reduces bending strength by 31.25 percent and deflection by around 11.2 percent for VE samples. Changing the power-law exponent from 0.5 to 10 increases fatigue strength by 35 %.

Abstract. Vehicles are called suborbital if they either move along a ballistic trajectory with a flight velocity sufficient to reach altitudes of up to 100 km or more, but insufficient for becoming an orbiter, or fly to altitudes of 100 km or more strictly vertically, but do not become artificial satellites of the planet, even if they reach sufficient velocity at some point. In both the first and second cases, this will be considered a space flight if its height exceeds 100 km (the Kármán line). Despite the active development of the suborbital rocket science in the world as a means of solving many scientific and technical problems in the space and defense industries, scientific research and engineering education, the development of suborbital rocket science in Ukraine has so far remained, at best, at the level of achievements of the 1960s and 1970s and has been supported by numerous amateurs. This article presents the results of the creation and development of a design and technological system for the development and operation of ultralight suborbital rocket systems as the basis for the creation of new models of domestic space rocket systems, rocket and missile weapons systems, the development of innovative technologies in the field of rocket science in general,  practical training of highly qualified specialists for the space industry. This paper presents structural and layout diagrams of the developed suborbital rockets, design and technological solutions for the creation of on-board radio-electronic equipment and rocket engines, design modeling, bench and flight tests. The presented design and technological system is already used today at Oles Honchar Dnipro National University for comprehensive practical training of specialists in the field of creation and operation of rocket technology and missile and rocket weapons.

Annotation. Recent success in development of the technology stipulated the appearance of advanced additive manufacturing aimed to shift conventional subtractive manufacturing from its position in the engineering field. Thus, for LPRE manufacturing there is an obvious advantage of additive manufacturing in terms of ability to produce single-piece parts with complex geometry must be seriously considered. In the modern world there is a constant competition between complex engineering decisions and cost efficiency of the production on the market of liquid propellant rocket engines. On the one hand, mixing head is one of the most demanding parts of LPRE in terms of designing. On the other hand, the earliest stage of its development starts with the choice of a type of mixing elements to ensure combustion stability, efficiency, and overall production cost [1]. Typically this step requires advanced knowledge in the real characteristics of produced injectors, or extensive experimental study should be carried out otherwise. In this work a problem of determining the characteristics of additively manufactured swirl injectors is considered. Laser Powder Bed Fusion [10] was chosen as a production method using Haynes 230 as a main material. A range of the swirl injectors with varied geometrical parameters was manufactured. Hydraulic testing was carried out in a wide range of Reynolds numbers for determining flow characteristics. Typically, discharge coefficient and spray angle are the desired values to know. Sauter mean diameter and film thickness were not studied due to lack of equipment. Considering a problem of prediction of the main characteristics of the produced injectors, a review on known equations for calculation of the main parameters was performed. Comparative analysis between calculated and experimental data was carried out. Results show that there is severe discrepancy between calculated values of characteristics of injectors and experimentally obtained data for additively manufactured swirl injectors. Even though the conducted study gives a base to form consistent conclusions of the behavior of the obtained characteristics, additional investigation is required.
Adaptive synergetic control for electronic throttle valve system
Authors: Mutlak Ahmed F. , Humaidi Amjad Jaleel
Published: November 2023

This study has developed adaptive synergetic control (ASC) algorithm to control the angular position of moving plate in the electronic throttle valve (ETV) system. This control approach is inspired by synergetic control theory. The adaptive controller has addressed the problem of variation in systems parameters. The control design includes two elements: the control law and adaptive law. The adaptive law is developed based on Lyupunov stability analysis of the controlled system, and it is responsible for estimating the potential uncertainties in the system. The effectiveness of the proposed adaptive synergetic control has been verified by numerical simulation using MATLAB/Simulink. The results showed that the ASC algorithm could give good tracking performance in the presence of uncertainty perturbations. In addition, a comparison study has been made to compare the tracking performance of ASC and that based on conventional synergetic control (CSC) for the ETV system. The simulated results showed that the performance of ASC outperforms that based on CSC. Moreover, the results showed that the estimation errors between the actual and estimated uncertainties are bounded and there is no drift in the developed adaptive law of ASC.

Published: November 2023

Blue swimming crab (BSC) (Portunus pelagicus) is the main fisheries commodity in Banten Bay, with the highest catch of catch occurring in the west monsoon. Increased fishing efforts have reduced the catch, as indicated by a decrease in the average size of carapace width. Overfishing might influence the life cycle and population structure of the BSC. This research aims to analyze the growth and mortality of the Blue Swimming Crab in Banten Bay, especially in the west monsoon. Blue swimming crab samples were obtained from the catch of fish trap and gillnet fishermen with landing sites around the Karangantu Archipelago Fishing Port. Growth, age, and mortality were predicted based on the measurement of total carapace width and body weight. Data were analyzed using Fisat II and Microsoft Excel. The frequency distribution of carapace showed one mode class which normally was distributed consisting of only one age structure group (cohort). The relationship between carapace width and weight of males or females resulted in a slope value (b>3) and was positive allometric, indicating that both sexes had a faster weight gain than the increase in carapace width. Growth parameters resulted asymptotic length (L∞); male 176.75 mm and female 176.46 mm. The growth was relatively fast, with a growth coefficient value of more than one. The mortality showed that the fishing mortality value (F);in males was 3.47 /year and in females 2.69/year was greater than the natural mortality value (M); males 1.25/year and females 1.22/year. Blue Swimming Crabs in Banten Bay had overfished as shown by the high fishing mortality value and there were still many BSC that were caught below the legal size allowed. Thus, catches should be controlled to keep the population and for sustainable fisheries.
Antioxidant and antithrombotic activities of the Distichochlamys citrea leaves extract

Published: November 2023

Distichochlamys citrea (DC) is an endemic ginger species used in treating associated-heart diseases in traditional medicine in Vietnam. However, scientific evidence to support the local use of this plant was limited. The present study aimed to investigate the antioxidant and antithrombotic activities of D. citrea extracts for the first time. The antioxidant activity of DC extracts was assessed by scavenging DPPH radical and measuring their total phenolic content (TPC). The antithrombotic activity was evaluated by inhibiting platelet aggregation and prolonging blood coagulation. Volatile components elucidated by GC-MS were docked with typical platelet receptors, including COX-1 and P2Y12. Results showed that the methanol extract of D. citrea exhibited a stronger DPPH scavenging ability (IC50 = 0.33 ± 0.00 mg/mL) and a higher TPC (8.09 ± 0.21%) than other extracts (p < 0.05). On the other hand, the hexane extract of D. citrea (DC-HX) had a remarkable inhibiting impact on ADP-, collagen- and ristocetin–induced platelet aggregation in a dose-dependent manner (Pearson’s correlation, r > 0.90, p < 0.05). In contrast, this extract did not lengthen the clotting time through any factors, such as PT (prothrombin time), and TT (thrombin time), except for APTT (activated partial thromboplastin time) at 4 mg/mL of the extract. GC-MS revealed that oxygenated hydrocarbons (54.45%) dominated the volatile profile of DC-HX, followed by sesquiterpens (37.18%) and diterpenes (6.66%). In the platelet aggregation process, several compounds in DC-HX were firmly bound to COX-1 and P2Y12, which might partly explain the significant antiaggregatory activity of this fraction. In conclusion, Distichochlamys citrea may be a potential source of active phytoconstituents for treating radicals- and cardiovascular-associated diseases.

A educação ambiental permite que pessoas construam valores sociais, conhecimentos, habilidades, atitudes e competências voltadas à conservação ambiental. Este estudo pretendeu estimular crianças na prática de observação de aves, para promover a educação ambiental, o letramento científico e o protagonismo infantil. O projeto #vempassarinhar consistiu em 12 encontros presenciais bimestrais, entre 2021 e 2023, com duração de 1,5h. Estes encontros incluíram uma apresentação teórica e uma caminhada para a observação de aves, com o auxílio de binóculos, em uma de três áreas localizadas no Estado do Rio Grande do Norte, Brasil: Parque Ecológico Mauricio de Oliveira e campus universitário da UFERSA, em Mossoró, e área verde e costeira em Tibau do Sul. O público-chave incluiu principalmente crianças de 7 a 11 anos, da rede pública de ensino. Como instrumento de apoio à aquisição do conhecimento, foram utilizados desenhos impressos para colorir, de aves nativas, e a prática de dobradura de papel. Participaram deste projeto 60 crianças e 20 jovens, sendo registradas, no total, 28 espécies de aves. Mais da metade das crianças e jovens demonstraram alguma habilidade na identificação das aves, reconhecendo características típicas, como cores das penas e formato do bico e da cauda e no uso de binóculos. Embora a atividade de pintura e dobradura de papel tenha sido opcional, todas as crianças optaram por realizá-las, seguindo o mesmo padrão de coloração da espécie-chave. A prática de observação de aves, quando conduzida de forma adequada, pode contribuir para habilidades e competências voltadas à conservação e sustentabilidade ambiental.

Urticaria is a common disease; its various clinical variants are diagnosed in 15–25% of people in the global population, and a quarter of all cases belongs to chronic urticaria. The prevalence of acute urticaria is 20%, and 2.1–6.7% in child population, whereas acute urticaria is more common in children than in adults. The prevalence of chronic urticaria in adults in the general population is 0.7 and 1.4%, and 1.1% in children under 15 years of age, according to the systematic review and meta-analysis, respectively. This article covers features of epidemiology, etiology, and pathogenesis of the disease with particular focus on differential diagnostic search. Guidelines on treatment and step-by-step therapy scheme (both based on principles of evidencebased medicine) for pediatric patients were presented. Clarification on the analysis of the therapy efficacy and the degree of disease activity was given.
Enhance resilience in timber connections with shape memory alloy and densified veneer wood

Dowel-type timber connections are commonly found in historic buildings and require reinforcement and repair to ensure that their resilience against natural disasters is maintained. This study aims to enhance the resilience of dowel-type connections by equipping them with shape memory alloy (SMA) dowels and densified veneer wood (DVW) reinforcement. The research findings reveal that the performance of SMA bars under cyclic bending is superior to that of steel, in terms of self-centring effect and ductility. Dynamic testing of the SMA-dowelled timber connections shows that connections using SMA exhibit lower residual deformation and better self-centring than those using steel. Additionally, the DVW reinforcement improves not only the self-centring but also the resistance of the SMA-dowelled connection. The comparison between solid bars and tubes shows that the solid bars perform better in terms of damping, resistance and self-centring. These results demonstrate the potential of developing resilient timber connections and improving the performance of SMA-dowelled timber connections.
Grouting effects in rectangular pipe jacking: centrifuge modelling and field data
Authors: Cao M. , Ma X.
Published: November 2023

Extensive field monitoring and a series of centrifuge model tests of grouting for rectangular pipe jacking were carried out to investigate the mechanism of grouting and its effects. An innovative jacking grouting device was developed to model the entire grouting process in a centrifuge test. Validation work was carried out by comparing the ground settlement between the centrifuge model test results and the field results, and reasonable agreement was obtained. The experimental results show that grouting slurry with low fluid loss and high viscosity is more conducive to controlling ground settlement during tunnelling; the ground settlement is strongly influenced by the grouting pressure. Within a certain range, increasing grouting pressure is conducive to controlling settlement; however, excessive grouting pressure will lift the ground surface.

Published: November 2023

Introduction: This article is the product of research on reducing the number of intermediaries by making use of Crowdfunding as an alternative source of low-cost financing, developed at the Universidad Distrital Francisco José de Caldas, in 2023. Problem: Although the term Crowdfunding is not new in the financial field, it is not very well known by the community, which means that it has not been applied as a recurrent financing alternative for projects or businesses in Colombia. Objective: This article presents a collaborative financing model for higher education institutions in Colombia, mainly for research groups oriented to the generation of new knowledge or spin-offs, with the aim of providing alternatives to classical financing models. Methodology: A literature review was conducted using the PRISMA methodology to identify, evaluate, and synthesize the existing body of knowledge produced by researchers, academics, or professionals. Results: The scope of this literature review encompasses the different types of crowdfunding, including its evolution over time and its inclusion in various economic areas. Additionally, it helps to visualize the level of knowledge about this concept among different university groups. Conclusion: The literature review examines the state of crowdfunding in Latin America, highlighting the lack of research compared to other regions. The impact of crowdfunding in various sectors, including technology,finance, and legislation, is emphasized. Furthermore, the need for theoretical reflection on how crowdfunding affects projects in the Southern Cone region is noted. The objective is to increase understanding and knowledge of crowdfunding among Latin American entrepreneurs and young people.
Ockham’s Razor, or the Murder of Concreteness. A Vindication of the Unitarian Tradition
Authors: De Monticelli Roberta
Published: November 2023

The notion of de re truth (Conte, 2016) is put to work in this paper (§ 1). It introduces us to a confrontation between a metaphysics of desertic landscapes, as presented in a stunning poem by Achille Varzi and Claudio Calosi, The Tribulations of Philosophye (§ 2), and an ontology of the lifeworld, as a long-term project based on the key concept of bonds (De Monticelli, 2018). The rich and structured objects of the everyday world are infinite sources of information and cognitive adventure (§§ 3, 3.1., 3.2). Or so I will claim against Varzi’s skepticism about ordinary language, common sense, and ontological realism (§ 4). Far from encouraging our minds to stick to concrete individual things, Ockham’s Razor has been the murder weapon in the dismission of concreteness and the sensible world from the intellectual horizon of Modernity (§§ 5, 6). The “Unitarian Tradition” is a half-playful denomination of a quite real, albeit ignored, alternative theory of individuality (and hence concreteness), brilliantly represented by Boethius, Duns Scotus, and Leibniz. Classic phenomenology quite independently revived it and brought it up to modern analytic standards of rigor and formality (§ 7).
Subjective Meanings and Normative Values in Alfred Schutz’S Philosophy of Human Action
Authors: Morujão Carlos
Published: November 2023

In his explanation of human action Alfred Schutz resorts mainly to Max Weber’s notion of subjective meaning and Husserl’s notion of type. For him subjective meaning seems more important to understand human action than the fact that social actors internalize normative values. Accordingly, validity has mainly to do with projects of action, with fulfilled (or unfulfilled) expectations and to the stock of knowledge available, along with the actor’s system of relevances. This raises two characteristic Schutzian problems: 1) the relation between the subjective meaning of an action and the objective criteria (namely, the juridical and the ethical ones) according to which any action can be evaluated; 2) the relation between an actor and his fellow human beings that arguably share the same system of relevances and act in the same normative framework. In this paper, I intend to offer an analysis of these issues, resorting mainly to Schutz’s 1934 book Der Sinnhafte Aufbau der Sozialen Welt, and in some unpublished manuscripts.
L’ottimizzazione della terapia basata sull’integrazione dell’ecocardiografia e dei peptidi natriuretici in pazienti ambulatoriali con scompenso cardiaco
Authors: Dini Frank L.
Published: November 2023

Lo scompenso cardiaco è una condizione progressiva che conduce alla riduzione della portata cardiaca e/o all’elevazione delle pressioni di riempimento del ventricolo sinistro. Risulta tuttavia complesso valutare la gravità del quadro clinico solamente sulla base dei dati clinici. La classificazione originale Diamond-Forrester, basata sui parametri emodinamici del cateterismo destro, permette di ricavare informazioni sulla portata cardiaca e riconoscere la presenza di segni indiretti di congestione polmonare. Essa è stata introdotta per valutare la gravità e trattare i pazienti, classificandoli in categorie denominate: warm/dry, cold/dry, warm/wetecold/wet. Più recentemente la valutazione invasiva del profilo emodinamico è stata sostituita da valutazioni non invasive ottenute con l’ecocardiografia. È possibile ricavare così stime del flusso anterogrado (portata cardiaca) e della pressione di riempimento del ventricolo sinistro sia in casi acuti che cronici. Questa classificazione può essere utilizzata per identificare i pazienti ad alto rischio di eventi avversi, eventualmente in associazione alla valutazione dei peptidi natriuretici (PN), e per personalizzare la terapia per antagonizzare i sistemi neuroumorali, ridurre la congestione e preservare la perfusione tissutale e renale. I maggiori benefici della terapia medica condotta in accordo alle Linee Guida sono da attendersi nei pazienti con profilo warm-dry, che sono quelli che più frequentemente rispondono con il rimodellamento ventricolare inverso, mentre trattamenti più selettivi e personalizzati guidati dall’ecocardiografia e dai PN sono necessari in pazienti con congestione persistente e/o ipoperfusione tissutale e renale per raggiungere gli obiettivi terapeutici e per evitare la stimolazione ulteriore dei sistemi neuroumorali come effetto dell’uso inappropriato di farmaci vasodilatatori o inotropi negativi. Pertanto, il monitoraggio emodinamico attraverso indicatori clinici, strumentali e bioumorali permette l’implementazione della terapia attraverso la personalizzazione del trattamento farmacologico e degli interventi.
Performance evaluation of ceramic insulators coated with titanium dioxide films to reduce soiling

Published: November 2023

The soiling of in-service electrical insulators exposed to the atmosphere is a major problem in power transmission lines. Several inorganic and organic particulate materials are deposited on insulator surfaces forming a layer that could become conductive in the presence of moisture. This produces different phenomena that could deteriorate the insulating properties of the material and eventually lead to its rupture, affecting the electrical energy supply. Currently, a method based in the application of a titanium dioxide film is being developed. This method tries to minimize the pollution accumulation on the porcelain insulators without affecting their electrical properties. In this work the performance of two different thicknesses of the coating film on the porcelain insulators was evaluated by means of contact angle, adhesion, leakage current, dry-flashover voltage and erosion laboratory tests. Finally, the in-service behavior of coated and no-coated insulators installed in a power transmission tower was evaluated. The coated insulators showed a good performance in the laboratory tests. Moreover, before 5 months of exposure in the energized power line, a decrease in the soiling was observed.
