The influence of oral contraceptives on the exercise pressor reflex in the upper and lower body
Authors: Pereira T. J. , Edgell H. 
Published: July 2024

AbstractPrevious research has demonstrated that oral contraceptive (OC) users have enhanced cardiorespiratory responses to arm metaboreflex activation (i.e., postexercise circulatory occlusion, PECO) and attenuated pressor responses to leg passive movement (PM) compared to non‐OC users (NOC). We investigated the cardiorespiratory responses to arm or leg metaboreflex and mechanoreflex activation in 32 women (OC, n = 16; NOC, n = 16) performing four trials: 40% handgrip or 80% plantarflexion followed by PECO and arm or leg PM. OC and NOC increased mean arterial pressure (MAP) similarly during handgrip, plantarflexion and arm/leg PECO compared to baseline. Despite increased ventilation (VE) during exercise, none of the women exhibited higher VE during arm or leg PECO. OC and NOC similarly increased MAP and VE during arm or leg PM compared to baseline. Therefore, OC and NOC were similar across pressor and ventilatory responses to arm or leg metaboreflex and mechanoreflex activation. However, some differences due to OC may have been masked by disparities in muscle strength. Since women increase VE during exercise, we suggest that while women do not display a ventilatory response to metaboreflex activation (perhaps due to not reaching a theoretical metabolite threshold to stimulate VE), the mechanoreflex may drive VE during exercise in women.
Decompositions of Inequality and Poverty by Income Source
Authors: Urban Ivica , Bezeredi Slavko , Leventi Chrysa 
Published: July 2024

Abstract
There is ample empirical literature on the contributions of different income sources to total income inequality. In contrast, studies estimating the contributions of income sources to income poverty are scarce. This paper presents a new decomposition of the Foster–Greer–Thorbecke poverty index, based on a marginal approach previously employed to decompose income inequality. We apply these marginal decompositions to data for 15 EU countries and classify six income sources according to their impact on inequality and poverty. Our results indicate that there are significant differences in the contributions of income sources to poverty compared to their respective contributions to inequality.

AbstractObjectivesThe research aims to investigate the effect of vitamin D supplementation on the efficacy ofHelicobacter pylorieradication therapy and to find new drug combinations for the eradication of the bacterium.MethodsA total of 128 children participated in the research. They were distributed under the following criteria: group A were children who tested positive forH. pyloriand were treated with the standard so-called triple therapy including vitamin D; group B were children who tested positive forH. pyloriand received the standard triple therapy without including vitamin D in the treatment; and group C were children who tested negative forH. pylori. After endoscopic examination, additional venous blood samples were taken from the children to determine vitamin D levels. A controlled study was carried out 45 days after the initial treatment.ResultsThe overall success rate of eradication therapy was 84.1 %. In group A, the success rate of treatment was 93.5 %, contrary to group B, where the success rate was 75 %. Although there was a difference in the percentage ofH. pylorieradication therapy in the main group compared to the control group, there was no significant difference in group B. The success rate of eradication is p=0.082.ConclusionsFollowing the research results, the addition of vitamin D to the standard triple therapy regimen forH. pylorihad no effect. It can therefore be concluded that vitamin D does not significantly increase the efficacy of eradication therapy.

Abstract
The geometry and sharpness of the cutting tool have a substantial impact on the final product’s quality. The geometry of cutting edges is altered throughout the machining process, and wear causes the cutting edge to become dull. This causes increased surface roughness, dimensional inaccuracy, cutting forces, chatter, and vibration. The present research focuses on tool wear (Vb) under dry machining conditions during ball end milling of Ti6Al4V alloy. The experiments are conducted using the full factorial design of experiments with three parameters, viz. feed (f), depth of cut (A
t), and rotational speed (S) at three levels. A total of 27 experiments are conducted with one replicate. Artificial neural network (ANN) with 3-18-2-1 architecture is used for the study of the tool wear monitoring (TWM) system. Results revealed that the TWM model is highly adequate, with R
2 = 99.89% and R
2adj = 99.65%. The percentage contribution of A
t is the highest, amounting to 80.6%, followed by feed of 12.46%. The rotational speed has the least contribution to tool wear, amounting to 1.5%. From ANN modeling, R
2 value testing is found to be 0.9974, which is close to unity and reveals that the trained model excellently fitted the testing data. The model accuracy is also found to be 96.46%.
Transforming Artistic Practice: Collingwood, Adorno, and the Diseases of the Mind
Authors: Schaefer Max 
Published: July 2024

Abstract
This paper addresses the views of R.G. Collingwood and Theodor Adorno on the role of amusement and art in what each of them saw as the crisis of contemporary Western civilization. We will begin by showing how the aesthetic theories of Collingwood and Adorno develop out of their shared concerns about the harmful effects of amusement and bad art on the consciousness of human beings. We will argue that a productive dialogue between these two figures clarifies that the value of art consists in its ability to remedy the corruption of the mental and emotional lives of human beings and in helping to fashion a different social and political order. As part of this, we will show how, despite appearances, Adorno’s aesthetic cognitivism and Collingwood’s expression theory of art agree with and complement one another in significant ways. In establishing this point, this work will leave us with an understanding of art that is more comprehensive and better equipped to address the crisis of contemporary Western society.

Authors: Amran Muhammad S. , Roslan Muhammad Z. , Sommer Werner 
Published: July 2024

Abstract

Purpose of review
The current rise of digital technologies is causing adolescents to spend more time on their digital devices, especially since the lockdown period of the pandemic. Adolescents are among those who are affected by lifestyle changes and are at risk of digital addiction due to the overuse of digital technologies. This opinion paper discusses the possible risk of loneliness among adolescents due to the overuse of digital devices. In this article, we would like to propose the concept of digital abuse and its risk of loneliness, as well as discuss some proposed solutions by referring to recent statistics and research evidence to reduce digital abuse among adolescents.

Recent findings
Evidence from previous studies highlights the association between digital addiction and loneliness among adolescents. Overusing digital devices among adolescents is also associated with various physical and psychological side effects.

Summary
Recent findings support the rapid rise of digital device usage among adolescents and its contributions to digital use. More research is needed to support existing interventions, provide early screening, and combat digital addiction to protect adolescents from the risks of loneliness due to the overuse of digital devices.

Published: July 2024

Abstract

Objectives
Adolescent suicide is a significant global public health concern. Although numerous studies have investigated factors that influence the risk of suicide among adolescents around the world, limited data are available in the Malaysian context, especially among the diverse ethnic communities of Sarawak. This study aimed to determine the factors associated with the risk of suicide among adolescents in Sarawak, Malaysia.

Methods
A community-based cross-sectional study was conducted among 1,344 adolescents in Sarawak using face-to-face interviews. Hierarchical binary logistic regression analysis was performed to identify factors that determine the risk of suicide among adolescents.

Results
Two predictive models were constructed. Both models revealed that being female (OR=1.578, 95 % CI: 1.191, 2.092, p=0.001), having Malay ethnicity (OR=1.733, 95 % CI: 1.236, 2.429, p=0.001) and having a disease significantly increased the risk of suicide (OR=1.895, 95 % CI: 1.221, 2.942, p=0.004). In particular, Model 2, which showed a better fit, found that occasional religious practice (OR=1.610, 95 % CI: 1.126, 2.303, p=0.009), poor parental relationships (OR=1.739, 95 % CI: 1.035, 2.922, p=0.037) and higher addiction (OR=1.015, 95 % CI: 1.008, 1.022, p=0.001), depression (OR=1.919, 95 % CI: 1.241, 2.968, p=0.003), and stress (OR=2.707, 95 % CI: 1.689, 4.340, p=0.001) scores were significantly associated with an increased risk of suicide.

Conclusions
This study sheds light on multiple factors that contribute to the risk of suicide among adolescents in Sarawak. These findings underscore the importance of holistic prevention strategies, including psychological and social dimensions, to mitigate the risk of suicide in this population. Further research is warranted to understand the complex interplay of these factors and guide the development of targeted interventions.
Vague Disagreements: Vagueness Without Arbitrary Stipulation
Authors: Magnell Elsa 
Published: July 2024

Abstract
According to Ruth Chang (2002, 2022), incommensurability in hard cases cannot be cases of vagueness. This is because vagueness, unlike hard cases, can always be resolved by arbitrary stipulation, leaving no resolutional remainder or substantive disagreement. Contrary to this, I argue that Chang’s argument fails because proponents of the vagueness view are in no way necessarily committed to the claim that vagueness always can be resolved by arbitrary stipulation. In fact, there seems to be no reason to assume that vagueness could not accommodate our intuitions about resolutional remainder and substantive disagreements in a satisfying way. If we want a simple theory, and if at least some incommensurability is vagueness, this could then be a reason for understanding incommensurability as vagueness; and perhaps even rejecting parity.

Published: July 2024

Abstract
This study develops a 3D model of a Christmas tree using cathodic protection technology and conducts numerical simulations on the Q355ND framework of a shallow Christmas tree. The boundary element method is employed for modeling, examining the distribution of protection potentials under varying corrosion layer breakage rates, anode numbers, and positions. The influence of sacrificial anode parameters on the cathodic protection effect of the Christmas tree is also investigated. The findings reveal that when the breakage rate of the anticorrosion layer reaches 35 % during Christmas tree operation, the sacrificial anode fails to provide complete protection. However, if the coating breakage rate is 10 %, reducing the number of anodes by six can still achieve a protection potential of −850 mV. Thus, it is imperative for Christmas trees to maintain a corrosion protection layer breakage rate below 35 %. Beyond this threshold, sacrificial anodes exhibit minimal effectiveness in preserving their integrity.
Mechanical analysis of hybrid structured aircraft wing ribs with different geometric gaps
Authors: Akdoğan Tümay Battal , Sülü İsmail Yasin 
Published: July 2024

Abstract
Wing ribs, which play a critical role in aviation, are an important design element, especially for unmanned aerial vehicles. Aircraft wing ribs are structural elements that generally extend from the wing root to the tip, used to maintain the shape of the wing, provide aerodynamic stability and add durability to the wing surface. In this study, the wing root rib of the MQ-1B Predator unmanned aerial vehicle were modeled with cavities with different geometric structures and its mechanical behavior were examined. Wing rib structures were created from circular, elliptical, slot and beam geometry gaps. The hybrid structure was created by considering the combined use of Carbon–Kevlar–Aramid. In the hybrid structure, the thickness of each fiber layer was taken into account as 0.25 mm and the wing rib consisted of six layers. The effects of different fiber angles in hybrid composite structures were also examined. As a result of the analyses, equivalent stress (von-Mises stress) and total deformation results were examined.

Abstract
Demographic change is causing society to age. At the same time, technological progress is changing the way ageing individuals are cared for and medically treated. Several smart wearables and garments have recently been developed for this purpose. Based on previous research, we see a research gap in the use of smart clothing in the care and support of elderly people, especially with regard to concrete application potentials and example products. The aim of this study was to provide an overview of the latest studies and developments in smart clothing with a focus on usability and acceptance for an elderly individuals. A systematic literature search was performed in five databases using a predefined set of keyword. A total of 169 articles published between 1/2000 and 2/2023 were identified and assessed. The literature search followed a previously prepared research protocol according to the criteria of a systematic literature search. The research field of smart clothing is expanding with smart shirts being a major focus; however other products are also being investigated, each with specific capabilities. In particular, vital parameters are constantly optimized; representative products are described and assessed according to their potential applicability to elderly people. The future applications of smart clothing in health care are promising. Many studies on basic applications of smart textiles have been done, and some studies have already involved older people. Furthermore, newly developed suggestions for possible categorizations of smart wearables as well as smart clothing as a subtype are presented based on the researched literature. We found an overall positive impression of the development and application of smart clothing, especially in geriatric settings. However, aspects such as data collection, skin compatibility, wearing comfort, and integration of geriatric factors into known acceptance models need further investigation. Over the last two decades, there have been many developments in the field of smart clothing. For the care and support of elderly people, smart clothing is an important development with great potential. Continued advancement in these products is needed to adequately address the special needs of older people.

Published: July 2024

Abstract
In recent years, the massive use of pharmaceuticals has led to the detection of a large number of relevant residues in water. As emerging contaminants, pharmaceuticals residues in the environment pose a major threat to human health and ecosystems. Covalent organic polymers (COPs) possess high stability, uniform pore size, and easy functionalization, which have attracted great attention in water treatment. In this study, a novel covalent organic polymer was successfully studied by a simple synthesis method, combining p-phenylenediamine (Pd) and isophthalaldehyde (Is) via a Schiff-base (referred to PdIs-COP), which was used as an absorbent for the removal of indomethacin from aqueous solutions. The composite was characterized with scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) specific surface area and thermogravimetric (TGA) analysis. The effect of changes in the pH values and the adsorption time on the adsorption capacity was also investigated. The results of this study indicated that the absorbent had a high adsorption capacity for indomethacin. The adsorption capacity of PdIs-COP for indomethacin is 92.86 mg g−1 at pH of five and a contact time of 2 min. This shows that PdIs-COP is a novel material with good affinity for pharmaceuticals.
Istraživanje, razvoj i inovacije u Hrvatskoj (prvi dio) – Nacionalni inovacijski sustav i strateški dokumenti do 2020.
Authors: Banić Tomišić Zrinka , Crnić Duplančić Ivana 
Published: July 2024

Inovacije su ključne za razvoj gospodarstva i društva. Hrvatska je još krajem prošlog stoljeća počela razvijati inovacijski sustav, a odgovarajuće strategije i politike nakon ulaska u EU veže uz europske. One su važne za sve dionike inovacijskog sustava, posebice znanstvenu zajednicu i poslovni sektor jer, među ostalim, financijska sredstava usmjeravaju u prioritetna područja i aktivnosti. Dobro postavljen inovacijski sustav i dobro usmjerene inovacijske strategije preduvjeti su za kompetitivnost gospodarstva i bogatstvo društva. <br />
Ovaj rad donosi pregled strateških dokumenata u području inovacija i razvoja nacionalnog inovacijskog sustava (NIS), s posebnim fokusom na Strategiju pametne specijalizacije (S3) 2016. – 2020., te preporuke međunarodnih organizacija za unaprjeđenje istraživanja, razvoja i inovacija (IRI) u Hrvatskoj. Glavnim dosadašnjim rezultatima u području IRI-ja i razvoja NIS-a može se smatrati sljedeće: 1) prepoznata je važnost IRI-ja za gospodarstvo i društvo te potreba suradnje znanstvene zajednice s poslovnim sektorom i komercijalizacije rezultata istraživanja; 2) ministarstva nadležna za znanost i gospodarstvo postala su sunadležna za inovacijske strategije; 3) donesene su prve inovacijske strategije; 4) proces poduzetničkog otkrivanja, kao temelj S3, postao je i temelj NIS-a (pristup “odozdo prema gore”); 5) osnovane su agencije/institucije za financiranje projekata IRI-ja; 6) osnovani su uredi za transfer znanja i tehnologije da bi se podržala komercijalizacija rezultata istraživanja i ojačala suradnja znanstvene zajednice i poslovnog sektora; 7) povećana su ukupna ulaganja u IRI. <br />
Daljnji razvoj NIS-a, rezultati IRI-ja te potencijalni pomak Hrvatske na ljestvicama uspjeha u inoviranju uvelike će ovisiti o implementaciji međunarodnih preporuka u S3 do 2029. kao i o provedbi S3 u praksi.

Published: July 2024

Mikroplastika (MP) posljednjih desetak godina izaziva zabrinutost znanstvene zajednice zbog velike prisutnosti u okolišu, dok mogući štetni učinci još nisu u potpunosti poznati. MP su čvrste, polimerne čestice, s dodanim aditivima, netopljive u vodi dimenzija od 1 µm do 5 mm. Dosad je dokazana prisutnost MP-a u različitim dijelovima okoliša, poput tla, oceana, jezera, sedimenata i izoliranih područja poput Marijanske brazde. Ljudi su izloženi MP-u unosom kontaminirane hrane. Mnogobrojna istraživanja rezultirala su pronalaskom znatne količine MP-a u pitkoj vodi, flaširanim pićima, soli, morskoj hrani i sl. Zakonska ograničenja i dalje nisu na izravan način obuhvatila MP kao skupinu onečišćivala, ali se direktivom EU-a do 2024. godine želi usvojiti metodologija za kvantificiranje MP-a s ciljem uvrštavanja MP-a na popis praćenih onečišćavala. Postojeće metode analize MP-a, iako u razvoju, najčešće uključuju spektroskopske metode poput infracrvene spektroskopije s Furierovom transformacijom (FTIR) i Ramanove spektroskopije, koje mogu pružiti informaciju o veličini, broju i obliku čestice, ali i o tipu polimera. No, unatoč napretku, još uvijek ne postoje standardizirane metode za usporedbu rezultata različitih istraživanja. U ovom preglednom radu glavni je cilj pružiti pregled metoda analize i izazova s kojima se istraživači suočavaju. Kroz analizu raznih metoda, poput destruktivnih (pirolize) i nedestruktivnih (kao što su spektroskopske metode), dobiva se širi uvid u tipove polimera, broj, veličinu i oblik čestica. Međutim, nedostatak standardiziranih protokola za pripremu uzorka, analizu i obradu podataka otežava usporedbu rezultata i smanjuje pouzdanost istraživanja. Stoga je ključno propisati eksperimentalne uvjete da bi se osigurala kvaliteta istraživanja i omogućila meta-analiza te pregled prisutnosti MP-a u različitim okolišnim matricama.
Politeness strategies in Oprah Winfred’s talk show “Adele one night only “: gender and cultural pragmatics study
Authors: Surjowati Ribut , Kusnowati Siti 
Published: July 2024

The purpose of this paper is analyzing the types of politeness strategies employed by Oprah Winfred (OW) in her interview with Adel, a famous American singer, in her program called Adele One Night Only. it is descriptive qualitative study within the framework of pragmatic study. 12 data were obtained from YouTube which presented a talk show entitled “Adele One Night Only” hosted by Oprah Winfrey. The data were analysed using Brown’s and Levinson’s (1987) theory of politeness. The analysis started by exploring the forms of negative politeness from the host’s utterances, and continued to the forms of negative politeness. In each of the analysis, the writer explained the host’s hidden purposes and the expectations from the interviewee and the correlation between gender, culture and types of politeness strategies used from the point of communication aims and cultural values.The findings shows that OW used positive politeness with eight different strategies and negative politeness with 4 different strategies. The politeness strategies employed by OW were meant to build friendly and warm communication as if they are intimate friends and these findings support the theory that most women like talking which aims to keep in touch, especially with friends and relatives.
