Published: November 2022

AbstractBacterial infection is one of the biggest health issues in animals and humans. Antibiotic is commonly used in bacterial infection therapy, yet antibiotic misuse can lead into bacterial antibiotic resistance. This means antibiotic is less effective in therapy of resistant bacteria. Green betel leaf has been known as traditional herbal medicine with rich essential oil and consists of phenol with several derivatives that have antibacterial activity. The results of the research that have been carried out can be reported that green betel leaf has the potential to be antibacterial. This herbal can be used as alternative therapy because it is easy to get and have low-level toxicity. In this study we try to discuss about green betel leaf (Piper betle L) as antibacterial with activity against Gram-positive and Gram-negative bacteria by analyzing the component of the active compound and mechanism of action.keywords: antibacterial activity; green betel leaf; Piper betle L AbstrakInfeksi bakteri menjadi masalah yang sudah sering terjadi dan berdampak buruk bagi kesehatan manusia dan hewan.

Low-Density Lipoprotein (LDL) extracted from egg yolk (LDL) has recently known can eliminate the adverse effect associated in the use of fresh egg yolk. The role of LDL in liquid preservation at 4°C of ram sperm has not been explored. This research evaluates the effects of substituting egg yolk with LDL in ram sperm preservation at 4 °C on 5 days. The objective of this research was to assess the effects of substituting egg yolk with LDL for use as an extender in sperm preservation at 4°C, as well as on spermatozoa motility, viability, morphology, plasma membrane, and acrosome integrity, for 5 days. The semen was subsequently divided into five and diluted with Tris–fresh egg yolk (K), Tris–LDL5% (LDL5), Tris–LDL10% (LDL10), Tris–LDL15% (LDL15), and Tris–LDL20% (LDL20). The result showed a significant difference between LDL to fresh egg yolk for ram sperm quality (P<0.05). The effectiveness of LDL on sperm quality decreased following by its concentration. Even though up to 20% concentration of LDL, it can not preserve the quality of diluted semen for motility, viability, and plasm membrane integrity.

Abstract

OBJECTIVE
To evaluate the effect of a multidose acyclovir protocol on koi herpesvirus (KHV) viral load and mortality in a cohabitation challenge.

ANIMALS
180 koi fish.

PROCEDURES
Forty fish (shedders) were immersed in a 0.5 KHV plaque-forming units/mL static bath for 8 hours. Mock shedders were treated similarly but exposed to cell culture media. KHV shedders were then transferred into 8 tanks (5 shedders per tank) containing 10 naïve fish (cohabitants) each. Fish in the acyclovir group (AT) received a 10 mg/kg acyclovir intracoelomic injection 1, 3, and 6 days after the first confirmed KHV mortality. Positive controls (PC) were treated similarly but received sterile saline injections. Negative controls (NC) were exposed to mock shedders. Morbidity and mortality were evaluated daily for 50 days post-challenge. Quantitative PCR was used to determine viral load in the gill biopsies of shedders and cohabitants collected at days 19 (T1), 22 (T2), 25 (T3), 34 (T4), and 50 (T5) post-challenge.

RESULTS
Survival curves analyzed by the Gehan-Breslow-Wilcoxon method revealed a delayed onset of mortalities and a significantly lower KHV load at T2 and T3 detected in AT cohabitant fish (P = .042) compared to PC group. However, there were no significant differences in overall mortality or viral loads at T5.

CLINICAL RELEVANCE
The acyclovir protocol used in this study did not control viral infection or mortality at the end of the 50-day trial. Shorter intervals between injections could improve outcomes, but the additional stress inflicted by handling should be considered. Exploring other therapeutic alternatives and doses is warranted.
Here Be Dragons: The Evolution of Cyberspace from William Gibson to Neal Stephenson
Authors: Donets Pol , Krynytska Nataliya 
Published: November 2022

Abstract
The article focuses on the evolution of cyberspace from a myth-critical perspective: the presence of irrational and fantasy elements in seemingly rational and scientific cyberpunk as a subgenre of hard science fiction. Our research primarily focuses on two significant works: William Gibson’s Sprawl trilogy (1984-1988), an icon of early cyberpunk, and Neal Stephenson’s Snow Crash (1992), a switch to postcyberpunk. Moreover, we consider the other works of a broad genre of cyberpunk including The Matrix movies and conclude that the cyberpunk of the 1980s and 1990s presented cyberspace as an enchanted Terra incognita and blurred the line between rationality and irrationality, technology and magic. Emerging as a way of escaping the real world, as hope for immortality, transcendence or transgression (Foucault), the cyberpunk ‘matrix’ followed in the footsteps of fantasy, myth, religion, and utopia. In our view, the postcyberpunk ‘Metaverse’ of the 1990s is more ironical and ‘realistic’ as it appears, and the more familiar and routine the cyberspace became to people, the less romantic and mysterious it turned out to be. Nevertheless, the nostalgic attempts to return to the old, fantasy model of cyberspace were made in postcyberpunk almost immediately after its emergence.
Abortion Travels in Contemporary American Cinema: Parental Consent and the Bumpy Ride to Termination in Eliza Hittman’s Never Rarely Sometimes Always and Rachel Lee Goldenberg’s Unpregnant
Authors: Andreescu Raluca 
Published: November 2022

Abstract
Although abortion was legalized in 1973 through the US Supreme Court’s landmark decision in Roe v. Wade, it is state legislatures that have ultimately acted as the final arbiters on the matter ever since. As a result, only over the course of the last decade, more than two hundred abortion restrictions have been enacted nationwide in the United States. As more and more restrictions are put in place in an attempt at policing women’s bodies, the practice that came to be known somewhat inappropriately as ‘abortion tourism’ is becoming increasingly common. More and more women travel across state lines in order to benefit from a safe procedure while evading the legal limits imposed upon them in their home states. This is even more acutely so in the case of young, under-age women, as only a few states do not have parental consent statutes covering abortion provisions. It is against this background that my article discusses two recent movies which tackle the issue of teen pregnancy and ‘abortion mobility,’ Never Rarely Sometimes Always (2020) and Unpregnant (2020). I look at how both travel narratives illustrate, in different genres and manners, the hurdles (young) women have to navigate to gain access to necessary medical care and expose the state-sanctioned obstacles to abortion in two stories about female friendship and empathy above all.
Topological Methods in Signal Processing
Authors: Volić Ismar 
Published: November 2022

Abstract
This article gives an overview of the applications of algebraic topology methods in signal processing. We explain how the notions and invariants such as (co)chain complexes and (co)homology of simplicial complexes can be used to gain insight into higher-order interactions of signals. The discussion begins with some basic ideas in classical circuits, continues with signals over graphs and simplicial complexes, and culminates with an overview of sheaf theory and the connections between sheaf cohomology and signal processing.

Published: November 2022

AbstractThis paper introduces and compares the various techniques for identification and analysis of low frequency oscillations in a power system. Inter-area electromechanical oscillations are the focus of this paper. After multiresolution decomposition of characteristic signals, physical characteristics of system oscillations in signal components are identified and presented using the Fourier transform, Prony’s method, Matrix Pencil Analysis Method, S-transform, Global Wavelet Spectrum and Hilbert Huang transform (Hilbert Marginal Spectrum) in time-frequency domain representation. The analyses were performed on real frequency signals obtained from FNET/GridEye system during the earthquake that triggered the shutdown of the North Anna Nuclear Generating Station in the east coast of the United States. In addition, according to the obtained results the proposed methods have proven to be reliable for identification of the model parameters of low-frequency oscillation in power systems. The relevant analyses are carried out in MATLAB coding environment.

Published: November 2022

Abstract
This paper specifies and compares the ancillary services used by transmission system operators in selected countries within ENTSO-E (European Network of Transmission System Operators-Electricity) for operational needs of their transmission systems. The comparison of the ancillary services’ unit prices is also given. In addition, analyses of various experiences gained by ENTSO-E countries within their electric power systems in relation to initiatives supporting the power generation from renewable energy sources (RES) and the methods of their integration into the electric power system were made. Namely, depending on the total amount of RES, depending on the incentive system for electricity production from RES and the development of an organized electricity market, different balancing responsibility models for electricity producers from RES were established.
Management framework for higher education institution-based community innovation labs
Authors: Păunescu Carmen , Ruohonen Anna , Spencer Nicholas , Vavură Nicolae Marius 
Published: November 2022

Abstract
The paper aims at defining the management framework for community innovation labs (CILs) linked to higher education institutions (HEIs) by applying the Delphi method. CILs are regarded as experimental settings established in HEIs aimed at addressing societal challenges. Specifically, the research study investigated the following questions: (1) What is the HEI-based CIL purpose and role, which is beneficial to society; (2) What kinds of governance, business method, capabilities and core activities are necessary for the establishment of viable CILs in HEIs; and (3) What forms of added value generated by CILs have the most potential for benefiting society? Results indicate that during 2020s it is expected that CILs will play a significant role in designing the local, regional or country innovation agenda. Also, they are expected to establish networks of people and multi-disciplinary teams that can address various societal challenges, while aiming at catalysing deeper, more sustainable and more creative approaches to systemic change. In addition to reinforcing the conceptualisation of a HEI-based CIL, the research results indicate understandings of the role and priorities of HEIs in CILs. This, then, leaves open how a CIL can manifest across and within communities when operationalized through this developing management framework. The ongoing process of shaping the effective CIL governance and HEI collaboration calls for dialogue, exploration and pilot solutions.

Published: November 2022

Abstract
The COVID-19 pandemic disrupted higher education worldwide. Higher education institutions needed to adapt very rapidly to the crisis and a new environment, and also needed to revise their role in society. Higher education institutions can contribute to social innovation through research, education and helping to address citizens’ issues and communities’ needs, which is why the creation of social labs by higher education institutions has increased in the last decades. Social labs are spaces where higher education institutions experiment and test new ideas. However, social labs at higher education institutions are still a relatively new phenomenon and have not yet been examined sufficiently. Moreover, it is not fully known how COVID-19 affected social labs’ activities and impacted their establishment. To reflect on the current reality, this article focuses on two research questions: (1) How were social lab activities and partnerships affected during the pandemic? and (2) What impact has COVID-19 had on social labs? To answer these questions, a quantitative survey was conducted, and the data was analysed by quantitative and qualitative methods. The results showed that the biggest challenge lies in organisational processes and human resources management. Yet, it should be noted that COVID-19 also provided opportunities. They are mainly linked with an impulse to develop innovations and increase digitisation in social labs. The study showed that social labs with flexible organisational processes and human resource management were more successful in their adaptation to crisis conditions caused by COVID-19. In summary, this article provides insight into social labs in higher education institutions by bridging an existing knowledge gap in scientific literature, and expands on it by investigating pandemics as having a crisis impact on social lab development.

Published: November 2022

The development of well-targeted physical activity facilities, especially in residential areas, can improve the function of physical activity facilities not only as a means to maintain public health but also as a means of disease management. Designers, as subjects who can manipulate the human-built environment have a significant influence on how the built environment or the place where humans move can meet health requirements to improve well-being. Physical activity is significant to maintain health and improving immunity, besides that, physical activity has also been proven to be used as a means of treating various diseases. Recommendations for appropriate physical activity for certain diseases must be explicitly planned and in accordance with the conditions of each city area. This study uses qualitative and quantitative methods to examine the suitability of data on chronic diseases that develop in the city of Bandung to be able to plan appropriate physical activity facilities for residential areas. The results showed that the physical activity facilities provided had to be varied in terms of aerobic, anaerobic, interval training, and balance training, which could be adapted to people's preferences.
