Authors: Nedi Syahril , Effendi Irwan , Tanjung Afrizal , Elizal Elizal 
Published: June 2023

Background: The application of phytoremediation by utilizing plants has been used to control oil pollution in waters. One of the plants that can act as a phytoremediator is the hyacinth because this plant can reduce various pollutants including petroleum hydrocarbons. This study aims to study the reduction ability of petroleum hydrocarbons at different concentrations including improving water quality. Methods: This study consisted of one treatment (petroleum hydrocarbon) consisting of five factors with three replicates. The treatments consisted of 10 ppm (E1), 30 ppm (E2), 50 ppm (E3), 70 ppm (E4), 90 ppm (E5), and (E0) without aquatic plants as controls. The treatments were observed daily and measured from the first day (D-1), the seventh day (D-7), and the 14th day (D-14). The water quality in each treatment was also measured, such as water temperature, pH, and dissolved oxygen. Results: The results showed that the hyacinth plant was able to reduce hydrocarbon in terms of total petroleum hydrocarbon (TPH) by 79% while it was only between 17–27% naturally without the hyacinth. The reduction of TPH in the water was in line with the decrease of chlorophyll in the leaves of hyacinths, and it was followed by the increase of dissolved oxygen in the water media. Conclusions: In conclusion, hyacinths can reduce petroleum hydrocarbons and they can improve the water quality as well.

Published: June 2023

Aim of the studyFor individuals with depression, depression self-efficacy is important. This study sought to understand the factors that are associated with depression self-efficacy.Subject or material and methodsParticipants (N = 275) in a trial of an internet-based depression intervention completed the Depression Self-Efficacy Questionnaire [1].ResultsA 3-way (gender * treatment experience * family history of depression) interaction predicted depression self-efficacy. Women with treatment experience reported significantly lower self-efficacy scores compared to those without treatment experience. For men, however, family history of depression moderated the relationship between past treatment experience and self-efficacy. Thus, among men with family history of depression, those without prior treatment experience had the highest depression self-efficacy scores and those with prior treatment experience – the lowest, but this pattern was not observed in men with unknown or no family history of depression.DiscussionSelf-efficacy of depression appears to vary based on gender, past treatment experience, and the individuals’ family history of depression, and for some individuals, past treatment experience may be associated with reduced self-efficacy.ConclusionsFindings suggest possible targets for intervention aiming at increasing depression self-efficacy.

Authors: Karatoprak Serdar , Donmez Yunus Emre 
Published: June 2023

Aim of the studyPandemics have negative physical and mental effects on children and adolescents. However, our knowledge about the factors related to the mental problems experienced in this process is limited. This study aimed to examine the association between resources of Covid-19 related information exposure and sociodemographic characteristics and mental health problems during pandemics.Subject or material and methodsThis study was carried out with 1030 children. The sociodemographic characteristics of the participants and exposure to information flow about the Covid-19 pandemic were recorded. Psychiatric problems were assessed using the DSM-5 Level-2 Anxiety Scale, DSM-5 Level-2 Depression Scale, DSM-5 Level-2 Sleep Disorder Scale.ResultsThe mean age was found as 10.45 years. It was determined that 33% of the participants had moderate/high level anxiety symptoms and 16.1% had moderate/high level depressive symptoms. Girl gender was related with anxiety-depression symptoms and sleep disorders, living in urban area was related with anxiety symptoms, increasing age and presence of death due to Covid-19 were associated with depression symptoms. It was determined that information exposure through TV, internet and peer conversations is associated with anxiety-depression symptoms, and information exposure via internet and family conversations was associated with sleep disorder symptoms.Discussion.ConclusionsMeasures to be taken for both sociodemographic risk factors and the negative consequences of resources of information exposure may reduce the negative psychological effects of pandemics on children.
An exploration of the reach of the #MakeSpace4Research hashtag
Authors: Pope Felicity , Brady Richard , Tinkler Linda 
Published: June 2023

Background: Use of social media to communicate with and engage health professionals is increasing. A communications campaign at Newcastle upon Tyne Hospitals NHS Foundation Trust used a Twitter hashtag to improve the visibility of nursing, midwifery and allied health professionals research. Aim: This study aimed to explore the reach of the #MakeSpace4Research campaign during its first 12 months. Methods: Between November 2018 and 2019, data on all tweets containing #MakeSpace4Research were examined using an online analytical tool. The studied variables were: total reach; total impressions; unique authors; total retweets; total mentions; and top tweeters. All these were collated using two separate variables: matching tweets and impact. Findings: #MakeSpace4Research appeared in 6884 tweets, involving 1085 individual Twitter accounts, resulting in more than 16 million impressions. Mentions and impressions both increased threefold, and unique authors more than doubled over the 12-month period. A spike in activity was noted after the campaign was launched at a nursing, midwifery and allied health professionals research conference in May 2019. Conclusion: The #MakeSpace4Research campaign has the potential to connect online communities of research-interested nurses, midwives and allied health professionals.
Gender differences in acute care treatments for cardiovascular diseases
Authors: Girleanu Isabela , Connolly Leona , McCabe Catherine 
Published: June 2023

Background: This narrative review aimed to identify gender-related differences in multiple cardiovascular disease treatments and to provide an overview of the possible causes to aid in establishment of a cardiovascular disease (CVD) risk profile. Methods: A narrative review methodology was used. A systematic search of two databases, PubMed and CINAHL, sourced 245 articles. Results: Seven articles met the inclusion criteria. Three recurrent themes emerged from the literature. These were gender differences in the burden of CVD, gender differences in symptom presentation and gender differences in management and treatment of CVD. Conclusion: CVD can be expressed differently in women and men. Different approaches to diagnosis and treatment are required. The studies included in this review reflect findings reported in research conducted more than 10 years ago, suggesting that more focus is needed to define and add gender-related indicators to current risk assessments and management strategies.
Study of Hydrodnamic Pumping Effects of Fixed Axis Rotation in Eccentric Annular Flow Field
Authors: Guo Tong , Luo Tao , Lin Tianliang , Chen Qihuai , Ren Haoling , Yu Yuanhua 
Published: June 2023

Hydrodynamic effect is one of the key phenomena in journal bearing lubrication. Many researches have been carried out on the supporting force of journal bearing, the motion of suspension shaft and the lubrication effect. This paper studies the hydrodynamic effect from another point of view, that is, the pumping effect caused by the rotation of the eccentric shaft with fixed axis. The clearance between the rotor and the stator is divided into two sections by the inlet port and the outlet port. Their mathematical models are established and studied in polar coordinates. The pressure distribution and pumping flowrate in the flow field are studied theoretically. Under the conditions analyzed in this paper, an output flow larger than 90 ml/s could be generated, overcoming a load pressure of 0.5 MPa. In addition, the pressure distribution and pumping flowrate of the mechanism are affected by the pumping outlet orientation. According to the analysis results of the output angle range from π/8 to 3π/4, when the pump outlet angle is set near 3π/8 to π/2, the pumping flowrate reaches the maximum value of 91.83 ml/s, and nearly half 48% of the inflow liquid can be pumped out to the outlet.
Symmetry-free algorithm for spectrum allocation: parallel implementations and evaluation
Authors: Rouskas George N. , Gupta Shubham , Sharma Priya 
Published: June 2023

Our symmetry-free model for spectrum allocation (SA) in networks of
general topology leverages two properties: (1) SA is equivalent
to a connection permutation problem, and (2) in assigning
spectrum, it is sufficient to consider the allocation made by the
first-fit (FF) algorithm. This model opens up algorithmic approaches
that altogether sidestep spectrum symmetry, i.e., eliminate
from consideration the exponential number of equivalent solutions
resulting from spectrum slot permutations. Recursive FF (RFF) is such
an algorithm; it applies FF recursively to search the connection
permutation space and solve the SA problem optimally. Moreover,
parallelism is inherent in the spectrum symmetry-free model, as the
connection permutation space may be naturally decomposed into
non-overlapping subsets that can be searched independently.
Accordingly, RFF admits multi-threaded implementations that may be
tailored to the computing environment at hand. In this work, we
present two strategies for parallelizing the execution of RFF, and we
evaluate them experimentally using a comprehensive set of metrics. Our
experiments indicate that RFF explores a vast number of symmetry-free
solutions, and for moderate-sized networks, it takes mere seconds to
yield solutions that are either optimal or very close to the lower
bound.

Inscribed versus Invoked Attitudes: Appraisal Among Indonesian Teenagers in English Captions on Instagram
Authors: Himmawati Dian Rivia , Munandar Aris , Sajarwa Sajarwa 
Published: June 2023

On Instagram, Teenagers’ captions in English do not always describe the picture but symbolically express their feelings to their friends as a whole. In this case, English captions enhance status and authority and reveal the attitudinal evaluation related to feelings and values. This paper aims to discuss the self-presentation between Indonesian female and male teenagers on their emotional, critical and evaluative stance reflecting on English captions on Instagram when the captions talk about friends and their relationship. Appraisal theory proposed by Martin and White to reveal the attitudinal evaluation is applied in this study. From 500 English captions, 90 captions deal with 155 appraising items about friends. They are 112 female appraised items and 43 male appraised items. Caption's screenshots are used to collect the data. The invoked attitude data are coded by examining posted photos. The result of the research is (1) male and female teenagers prefer to express their attitude by using inscribed attitude rather than invoked attitude, (2) male teenagers expresses moreattitude through Affect, while female teenagers express more through Judgment, (3) negative appraisal is to used to emphasize the positive values in the form of a counter concession, for male teenagers to highlight togetherness, while for female teenagers are more focused on empathy, (4) both female teenagers and male teenagers use negation to show a positive attitude related to judgment propriety (ethical Judgment). Therefore, writing captions on Instagram provide an opportunity for male and female teenagers to express their attitudes as they imagine to show their strength without physically confronting the interlocutor.
Capillary Schwarz symmetrization in the half-space
Authors: Lu Zheng , Xia Chao , Zhang Xuwen 
Published: June 2023

AbstractIn this article, we introduce a notion of capillary Schwarz symmetrization in the half-space. It can be viewed as the counterpart of the classical Schwarz symmetrization in the framework of capillary problem in the half-space. A key ingredient is a special anisotropic gauge, which enables us to transform the capillary symmetrization to the convex symmetrization introduced in Alvino et al.https:/doi.org/10.1016/S0294-1449(97)80147-3.
The portrayal of women in Jordanian proverbial expressions: A thematic analysis
Authors: Al Rousan Rafat Mahmoud , Shatnawi Hadeel Nidal 
Published: June 2023

Abstract
Proverbial expressions are linguistic elements that represent the images and values of a society. This study examines the portrayal of women in Jordanian proverbial expressions. It attempts to answer the following question: How are women portrayed in Jordanian folk proverbs? To this end, seventy-eight Jordanian proverbs related to women were collected through interviews and from published folklore books. Employing thematic analysis, the data were classified into eight categories, namely, women as wives, unmarried women, women as mothers, women as daughters, widowed women, divorced women, women as relatives-in-law and women in general. The analysis also shows that women are represented both negatively and positively in all categories. However, the negative image of women depicted in the proverbs exceeds the positive one. Based on the conclusions, some future research was suggested.
Cerebral asymmetries in the processing of opaque compounds in L1 Polish and L2 English
Authors: Hwaszcz Krzysztof , Kędzierska Hanna 
Published: June 2023

Abstract
We report the results of a cross-modal priming study investigating the processing of opaque compound words, when followed by figuratively and literally related primes, in L1 (Polish) and L2 (English). Additionally, the half-divided visual field paradigm was used to verify which cerebral hemisphere is responsible for semantic decomposition, and whether the language status will lead to different activation patterns. The left hemisphere is generally believed to process the more salient or conventional meanings of figurative expressions, and the right hemisphere their less salient or unconventional meanings. However, this assumption has not so far been verified for compounds. The results suggest that both the figurative and the literal meanings of opaque compounds were processed significantly faster by the left hemisphere in the case of L1 Polish. No statistically significant differences were obtained for L2 English. At the same time, English compounds were overall processed significantly faster than Polish compounds.

Vitamin C and epigenetics: A short physiological overview
Authors: Pavlovic Voja , Ciric Milan , Petkovic Milan , Golubovic Mladjan 
Published: June 2023

Abstract
In recent years, ascorbic acid (vitamin C) has acquired great interest due to its multiple functions, which results in homeostasis of normal tissues and organs. On the other hand, it has been shown that epigenetic modifications may have an important role in various diseases and therefore are a focus of the extraordinary investigation. Ascorbic acid serves as a cofactor for ten-eleven translocation dioxygenases, which are responsible for deoxyribonucleic acid methylation. Also, vitamin C is required for histone demethylation, since it acts as a cofactor of Jumonji C-domain-containing histone demethylases. It seems that vitamin C may be a mediator between the environment and the genome. The precise and multistep mechanism of ascorbic acid in epigenetic control is still not definitely determined. This article intends to provide the basic and newly discovered functions of vitamin C that are related to epigenetic control. Also, this article will help us to better understand the functions of ascorbic acid and will provide the possible implications of this vitamin in the regulation of epigenetic modifications.
Parua magnis: Die Villenbeschreibungen des jüngeren Plinius im intertextuellen Größenvergleich (epistulae 2,17 und 5,6)
Authors: Beer Beate 
Published: June 2023

Abstract
Despite the frequent use of the antithesis of parua and magna in Latin literature, the expression parua magnis in Pliny 5,6,43–44 need not be read as proverbial but as a quotation of Vergil, georg. 4,176. This attribution follows from the naming of Vergil and of Aratus in epist. 5,6,43–44. Combined allusions as in 5,6,43–44, consisting of a quotation, the naming of the author and/or narrative structures, are a pattern in the corpus of the younger Pliny’s correspondence. The context of georg. 4,169–179, too, supports the attribution of the phrase as a quotation, since in Vergil’s lines a comparison of genres is made, which Pliny adopts for his own literary positioning in the descriptions of villas in epist. 2,17 und 5,6. Further, the attribution to Vergil’s didactic poem, in combination with the reference to Aratus, which other interpretations hardly take into account, permits a new understanding of the narrative structure of the villa descriptions and their allusive affinity not only to ecphrasis but also to didactic poetry.
Was the Commentary on Vergil by Aelius Donatus Extant in the Ninth Century? A Reappraisal
Authors: Danovi Vittorio Remo 
Published: June 2023

Abstract
That the Vergilian commentary by Aelius Donatus – one of the most influential late-antique commentaries that have not survived – was extant in the ninth century and available to some Carolingian scholars is still a widespread belief. The evidence in support of this thesis is said to have been provided by the Harvard Servianist J. J. H. Savage in three articles published between 1925 and 1931. In these articles, Savage claimed that a few marginal notes in one of the ninth-century primary witnesses to the DS scholia, the so-called ‘Vergil of Tours’ (Bern, Burgerbibliothek, Ms. 165), were drawn almost directly from Donatus’ commentary and that a marginal note in a roughly coeval Servian witness (Bern, Burgerbibliothek, Ms. 363) provided information about a place where a copy of the commentary could be found. A re-examination of the two manuscripts shows that the evidence adduced by Savage does not stand scrutiny and that the terminus post quem for the loss of Donatus’ commentary should be antedated by at least one century.
The Social Networking Function of Cicero’s Prefaces to the Philosophical Works
Authors: Dowson Christopher 
Published: June 2023

AbstractThe value of theprohoemiaor ‘prefaces’ to Cicero’s later philosophical works, composed in the last years of his life, has not yet been settled. Two schools of thought have emerged somewhat more clearly in recent times: one places a greater value on the prefaces as tools for understanding Cicero’sphilosophicaas a whole, the other applies a more skeptical approach, using a degree of caution as to the nexus between the prefaces and the treatises to which they were affixed. The article advocates for the latter camp, however not only to temper the recent emphasis the optimists have placed on the prefaces as key interpretive elements to the dialogues, but to refocus their importance as extensions of Cicero’s personal and social networking with other Roman elites of his time. I rely on two main lines of argument: the anecdotal evidence from Cicero’svolumen prohoemiorum, “book of prefaces”, mentioned in a letter to Atticus in 44bce, as well as a broader analysis of a deeper disconnect between Cicero’s prefatory rhetoric regarding Latin philosophical vocabulary compared with Greek and his translation practices in his treatises.
