Biocompatibility and Surface Integrity of Zirconia Ceramics Treated by Laser-plasma Driven Shock-waves
Authors: Shukla Pratik , Zhang Vincent , Shen Xiaojun , Villapún Victor M. , Cox Sophie , Swanson Phillip
Published: November 2022

This is a multi-disciplinary paper focused on the preliminary results of deploying laser shock treatment (LST) to ZrO2 ceramics. This work has significance in several industrial sectors for components that will benefit from strengthening. These components are, namely: dental implants; cutting and drawing tools; valves, bearings, pressure vessels, heat exchangers and high-performance scissors and knives, where modification of hard, brittle materials properties such as that of a ZrO2, can yield a performance boost. To elucidate the influence of LST on ZrO2 ceramics, an Nd: YAG laser was used, exhibiting (operating at discrete) laser energies of 17 mJ, 85 mJ and 170 mJ, a 2 mm spot size, a pulse repetition rate of 5 Hz and pulse duration of 10 ns was deployed at 532 nm wavelength. Investigation of ZrO2 ceramic surface integrity revealed a transition from a crack-free topology to a surface dominated by fractures, as the laser energy increased from 85 mJ to 170 mJ. Residual stresses obtained by incremental hole drilling (IHD) were measured to be tensile in the upper layer and the sub-surface layer. However, compression of -595 MPa was found in the sub-surface of the ZrO2 ceramic to a depth of 350 µm after LST, particularly in the transverse direction. Biological analysis metabolic activity measurements, indicated a rise in activity for all samples as the contact time increased (24 h, 3 d and 7 d). The as-received surface revealed a more limited change in metabolism, retaining similar biochemical levels during the first 3 days followed by a slight increase after a week of cultivation, bringing about significant increase in activity in all LST surfaces, relative to the as-received condition. This suggested that a ZrO2 LST exhibited enhanced cell response, particularly, after 7 days of contact-time. The overall outcome of this introductory paper, not only showed that ZrO2 ceramics, can be laser shock treated/peened, to induce some possible beneficial mechanical and physical effects, microstructural and surface topography changes, but also showed that LST can facilitate improvement in cell response to the ZrO2 ceramic. This opens-up, new prospects for treatment of ZrO2 based ceramics for biological applications such as tooth implant screws, where avoiding fractures from mechanical loading, strength enhancement, as well as biocompatibility are all important.

BACKGROUND

Post-stroke depression (PSD) is the most common psychiatric disorder after stroke and affects recovery of neurological function, ability to return to society, and quality of life of the survivors. Telehealth has been shown to improve depressive symptoms and quality of life of post-stroke patients. However, evidence from clinical trials has not been systematically synthesized.

OBJECTIVE

This study aims to systematically evaluate the effectiveness of telehealth interventions in reducing depression and anxiety symptoms of post-stroke depression.

METHODS

The Cochrane Library, PubMed, CINAHL, PsycINFO, CNKI and Wanfang Database were searched to identify randomized controlled trials (RCTs) on effectiveness of telehealth interventions for post-stroke depression from inception to November 30, 2021.The quality of included studies was assessed using the Cochrane risk of bias tool. Data extraction and quality assessment were conducted by two reviewers independently. RevMan 5.4 software was used for Meta-analysis. Data would be synthesized by either the fixed-effect (I2≤50%) or random-effect (I2>50%) model according to a heterogeneity test.

RESULTS

A total of 10 studies with 1717 participants were included, of which 8
were eligible for meta-analysis. Compared with the control group, the anxiety score of the telemedicine group was lower, with statistical significance (SMD=-1.05, 95%CI-1.22 to -0.89, P<.001), while no significant differences in scores in depression (SMD=-0.16, 95%CI-0.67 to 0.36, P=.54), quality of life (SMD=0.00, 95%CI-0.18 to 0.18, P=.99), limb function (SMD=0.46, 95%CI-0.26 to 1.18, P=.21), and daily living ability (SMD=1.95, 95%CI-1.39 to 2.29, P=.67) were observed.

CONCLUSIONS

Telehealth interventions could availably reduce anxiety symptoms in post-stroke patients, while it had equal salutary effects on depression with the conventional nursing. Therefore large-scale, high-quality randomized controlled trials are needed to further explore the potential of telehealth interventions in terms of mental health for post-stroke patients.

Tindak Tutur Ilokusi dalam Lirik Lagu EP “Miracles in December” Karya EXO
Authors: Leandro Jose , Prasetyanti Keren , Pniel Amanda , Megasari Jayanti
Published: November 2022

The communication process in a song lyrics’ story involves a speaker and a speech partner. Song lyrics are essential to reflect the message of a song. Therefore, the researcher sought to know the meaning, purpose, and context of speech in the song lyrics in the extended play (EP) entitled “Miracles in December” by EXO that consists of five songs: “Miracles in December”, “Christmas Day”, “The Star”, “My Turn to Cry”, and “The First Snow”. The researcher chose the “Miracles in December” EP as an object because this EP has elements of interesting speech acts to study in pragmatics. In this study, researchers use a theoretical approach which will focus on discussing illocutionary speech acts from Searle's theory. The method in this research is descriptive qualitative with the use of listening and note-taking techniques. The results of this study prove that in the “Miracles in December” EP there are 156 data of illocutionary speech acts consisting of 100 data of assertive, 29 data of directive, 15 data of expressive, and 12 data of declarative.
Barriers to Women Participation in Formal and Traditional Governance in Ghana
Authors: Dawda Tanko Daniel
Published: November 2022

Mainstreaming women through gender specific policies is an acknowledged precondition for achieving meaningful development in any developing country such as Ghana. Regrettably, it is only recently that issues of women participation have been recognized as such in the context of policy reforms in both administrative and local government arenas in Ghana. Even with that, recent local government reforms in Ghana have not given opportunity for the creation of quota for women in grassroots democratic institutions. In the context of governance, women’s concerns had surfaced intermittently and have merely been highlighted in political party manifestoes and agenda. Most areas of Ghana are rural and lack essential services. And considering their role in rural community development, the state of women’s participation in the governance process is crucial and deserves special attention if development is to be delivered in a more sustainable and efficient manner. To do this effectively, the obstacles to women participation must be unveiled and eliminated to overcome some of the challenges in rural development delivery. The study established that there are serious challenges in gender balancing both in terms of formal and traditional governance policy and reform agenda in Ghana. Consequently, female representation in both formal and traditional governance systems has been very minimal. Some suggestions have been recommended as the way forward in overcoming the obstacles to women participation in governance processes.

ASSESSING THE HIERARCHICAL HAMILTONIAN SPLITTING INTEGRATOR FOR COLLISIONLESS N -BODY SIMULATIONS
Authors: Aguilar-Argüello G. , Valenzuela O. , Velázquez H. , Clemente J. C. , Trelles J. A.
Published: November 2022

The large dynamic range in some astrophysical N -body problems led to the use of adaptive multi-time-steps; however, the search for optimal strategies is still challenging. We numerically quantify the performance of the hierarchical Hamiltonian Splitting (HHS) integrator for collisionless simulations using a direct summation code. We compare HHS with the constant global time-step leapfrog integrator, and with the adaptive one (AKDK). We find that HHS is approximately reversible, whereas AKDK is not. Therefore, it is possible to find a combination of parameters such that the energy drift is considerably milder for HHS, resulting in a better performance. We conclude that HHS is an attractive alternative to AKDK, and it is certainly advantageous for direct summation and P3M codes. Also, we find advantages with GADGET4 (Tree/FMM) HHS implementation that are worth exploring further.

Published: November 2022

The first analysis of the light curves of contact binaries ROTSE J135349.8+305205 (CB1) and 1SWASP J150957.5-115308 (CB2) using the Wilson-Devinney code is presented. Both binary systems are of the A-subtype with a shallow fill-out (20.8% and 15.8% respectively) and a difference in temperatures between the components of < 200 K. A mass-ratio of 0.302 is found for CB1, while for CB2 the interesting value of 0.904 is found. The short periods, 0.246 d for CB1 and 0.229 d for CB2, and their spectral type K suggests that these systems are near the shortest period limit. The absolute elements are estimated using GAIA parallaxes. CB2 is found to be at the beginning of its evolution, while CB1 will approach the final evolutionary stage. The sum of the component masses of CB1 is 0.813 M☉, below the mass limit of 1.0 − 1.2 M☉ assumed for the known contact binary stars.
SIMULATIONS OF UNEQUAL BINARY COLLISIONS EMBEDDED IN A TURBULENT GAS CLOUD FAR FROM A MASSIVE GRAVITATIONAL CENTER
Authors: Arreaga-García G.
Published: November 2022

We simulate the collapse of a turbulent gas cloud, in which we choose two sub-clouds. A translational velocity $\vec{r}_L$ or $\vec{r}_R$ is added, so that the sub-clouds move towards each other to collide. The radius and pre-collision velocity of the sub-clouds are chosen to be unequal, and both head-on and oblique collisions are considered. The simulations are all calibrated to have the same total mass and initial energy ratio α = 0.16, which is defined as the ratio of thermal energy to gravitational energy. We compare low-β models to a high-β models, where β is defined as the ratio of kinetic energy to gravitational energy. Finally, we consider the turbulent cloud to be under the gravitational influence of an object located far enough, in order to approximate the tidal effects by means of an azimuthal velocity Vcir added to the cloud particles apart from the translational and turbulent velocities mentioned above. We compare a low-Vcir model with a high-Vcir one.
AN ASTROPHYSICAL PERSPECTIVE OF LIFE. THE GROWTH OF COMPLEXITY
Authors: Sánchez F. , Battaner E.
Published: November 2022

The existence of life is one of the most fundamental problems of astrophysics. The intriguing existence of progressively complex and apparently improbable living beings should be a general tendency of life in the Universe. We are looking for general physical laws governing the growth of complexity in any astrophysical environment. We posit the existence of a vital scalar field. This scalar is sensitive to the gradient of the inverse of specific entropy, such that its distribution tends to very high values in the interior of living beings. Besides the classical mutations, vital field driven mutations only produce decrements of entropy. The field equations give rise to the existence of vital waves. This theory is able to deal with both the origin of life and the evolution of life. We show that the growth of complexity is accelerated by the vital field.
OBSERVATIONAL CONSTRAINTS ON THE HD 5980 WIND-WIND COLLISION

Published: November 2022

Analysis of spectral line profile variations observed over 6 decades in the Wolf-Rayet system HD 5980 lead to the conclusion that Star A, the variable member of the system, has always dominated the wind collision zone (WCZ), contrary to suggestions that before 1994 the stronger wind belonged to its close companion, Star B. The observed variations are caused by a combination of physical occultations, wind eclipses and emission and absorption originating in the WCZ. The effects caused by the leading WCZ branch, which folds around Star B, are clearly seen as it crosses our line of sight to Star A during the secondary eclipse. These effects can inform on the WCZ velocity and density structures. We speculate that differences in line profiles at the same orbital phase but at different epochs may be linked to changes in the WCZ radiative properties. The 2017-2020 spectra indicate that HD 5980 was in a higher activity state than during 2010-2015.
Bollywood Actresses’s Evolving Figure Consciousness & Role in Hindi Cinema: Comparative Study From 1950 to 2020
Authors: Pavhare Pravin D. , Rajput Dr. Amrita
Published: November 2022

Abstract: Bollywood is the name given to the Hindi film business because it is based in Bombay (Mumbai). For decades, Bollywood has been a popular source of entertainment for millions of people not only in India but also around the world. Dada Saheb Phalke launched the Indian cinema business with silent films, and from that time until now, Bollywood has experienced numerous ups and downs and undergone significant changes in terms of technology, fashion, and the impact of political, social, and cultural developments in the nation. The primary Hero (protagonist), The Heroine (his love interest), and the Villain (his enemy) are a few aspects that, despite all these variations, are consistent and common in Bollywood film plots. These components can be found in any Bollywood film from any era. Without it, a Bollywood film is incomplete. The Bollywood heroine has been the style symbol for decades, from Madhubala and Nargis of the 1950s to Sridevi and Madhuri Dixit of the 90’s to Deepika and Katrina of the 2020s. They might be seen as a reflection of the social and cultural attitudes about beauty parameters of the period. Women, in addition to young girls, also look up to and emulate these heroines for their beauty, fashion sense, and way of life. This study paper analyses the changes in the attractiveness and Physical appearance of Bollywood heroines, as well as the reasons for these changes.

Employee engagement refers to the commitment and willingness of employees to go beyond their defined tasks for ensuring the success of their organization. Prioritizing the development of engaged workers reaps substantial rewards for organizations in terms of productivity, efficiency, and effectiveness (Chiwawa, 2022). Employees’ job engagement has gained momentum in the past few decades, mainly due to the changing work dynamics, workforce diversity, and globalization (Awan, Aslam, & Mubin, 2019). The aim of this study is to identify the determinants of employee engagement in the emerging market among Silite zone teachers through a cross-sectional descriptive and explanatory research design. The total population of the study is 5,902, using Yamane’s formula 375 has been selected as a sample size with a stratified and simple random sampling technique. The collected data were analyzed by using correlation and regression models and a general linear model of univariate analysis of variance through SPSS version 26. The results of the study revealed that reward and recognition, work-life balance, training and development, and job characteristics are significant in determining employee engagement, whereas communication was found to be insignificant. The study recommends that Silite zone schools reconsider and continue the good work in reward and recognition practices, balancing employee work life, its ways of training and development for the teachers, and improving the job character.

ÖZET

Aksaray İli ve çevresinde 2015-2019 yılları arasında gerçekleştirilen Paleolitik Çağ konulu yüzey araştırmalarında önemli sonuçlar elde edilmiştir. Bu sonuçlardan bir tanesi 2018 yılında Armutlu Kasabası çevresinde keşfedilen taş kaynaklarıdır. Bu kaynaklar, Paleolitik Çağ sürecinde yontmataş alet yapımı için tercih edildikleri için detaylı şekilde incelenmişlerdir. Bu çalışmada hem arkeolojik hem de jeolojik analizler yer almaktadır. Taş kaynaklarının yontmataş alet yapımında tercih edilebilmeleri için yontulduklarında keskin kenar vermeleri ve ince taneli bir yapıda olmaları gerekir. Bu tanıma uygun olan çok sayıda taş türü vardır fakat detaylı bilgi içeren örnek sayısı azdır. Bu nedenle yontmataş yapımında kullanılan taş kaynaklarının jeokimyasal olarak da incelenmesi ve değerlendirilmesi önem arz etmektedir. Bu bağlamda söz konusu alanda yer alan tüm kaynaklar arkeolojik ve jeolojik olarak sınıflandırılarak analiz sonuçlarıyla birlikte ortaya konulmuştur. Bu sayede ileride bu tarzda yapılacak olan çalışmalar için de bir örnek teşkil edecektir.
Changes of intestinal microbiota in colorectal cancer and its potential ability to predict disease
Authors: Lu Fang , Zhou Jie , Lu Dongjia , Ye Li , Liang Hao , Lan Liuyan , Yang Xiping , Cui Ping , Huang Jiegang
Published: November 2022

Background：It is controversial whether colorectal cancer (CRC)
impacts intestinal microbial alpha (α) diversity, and although some
studies have suggested an association between intestinal microbiota and
cancer risk, few have been used as a marker for CRC diagnosis.
Methods：By searching PubMed and BioProject databases, we
reanalysed published raw 16S ribosomal RNA (rRNA) gene sequences and
metadata. We calculated α-diversity indices, screened the differentially
enriched genera and species shared among different studies, identified
potential CRC markers, and finally assessed the overall trend of these
indices. Results：The pooled analysis showed that based on the
fixed-effects model, α-diversity of the cancer group was lower than that
of the non-cancer group, and there was significant heterogeneity.
Heterogeneity was significantly reduced or eliminated when grouped by
geographic region, study scope, and sequencing platform. We also found
an association between gut microbiota and CRC. The genera
Fusobacterium, Parvimonas, GemellaCampylobacter, and Peptostreptococcus were only enriched
in the cancer group, while Faecalibacterium, Subdoligranulum, and
Fusicatenibacter were dominant in the non-cancer group. At the
same time, we also provide some evidence that Fusobacterium,
Gemella, Faecalibacterium, and Subdoligranulum have
diagnostic value in several studies and may be potential diagnostic
markers of CRC. Conclusions： This analysis indicates an
association between CRC and microbiota composition, and microbial
markers could be used as diagnostic indicators of CRC. However, future
studies should include more cohorts and wide sample sizes to identify
the role of the different microbiota in CRC.
Managing Peri-Mitral Flutter
Authors: W Michael Lim , Kistler Peter
Published: November 2022

The exponential rise in the incidence of peri-mitral flutter has
paralleled the increasing use of more extensive atrial substrate
ablation for atrial fibrillation (AF). Given the relative paucity of
randomised evidence to support its role in AF management, mitral isthmus
ablation should largely be reserved for patients with peri-mitral
flutter. Catheter ablation for peri-mitral flutter is challenging due to
complex anatomic relationships. The aim of this report is to review the
anatomic considerations and approaches to catheter ablation for
peri-mitral flutter.

underwent angioplasty of the bilateral superior renal arteries twice.
This highlights the need for a multidisciplinary approach in treatment.
Exponential forms and wavefunctions of the octonion angular momenta
Authors: Weng Zi-Hua
Published: November 2022

The paper aims to explore the exponential forms of octonion angular
momenta in the electromagnetic and gravitational fields, researching the
influencing factors and physical properties of octonion wavefunctions.
J. C. Maxwell first utilized the quaternions and vectorial terminology
to describe the electromagnetic theory. Nowadays, the scholars apply the
quaternions and octonions to study the electromagnetic fields,
gravitational fields, and quantum mechanics and so forth. The
application of octonions is able to describe the physical quantities of
electromagnetic fields and gravitational fields, including the octonion
field strength, field source, linear momentum, angular momentum, torque,
and force and others. According to the characteristics of octonions, the
octonion physical quantities can be rewritten into the exponential
forms. In particular, either the angular momentum or electromagnetic
moment may be dominant under certain circumstances, in the octonion
spaces. The product of the octonion angular momentum and Planck’s
constant can constitute a nondimensionalized octonion exponential form.
As a result, the octonion wavefunctions can be obtained from the
exponential forms of octonion angular momenta. When the direction of
multidimensional unit vector in the octonion wavefunction cannot be
determined, the imaginary unit can be used to substitute the
multidimensional unit vector. As a compensation measure, it is necessary
to replace one single octonion wavefunction, relevant to a
multidimensional unit vector, with several wavefunctions related to the
imaginary units. The dimension number of unit vector may be interrelated
to the color number of color charges in the quantum chromodynamics.
A re-examination of the circumscription of Saxifraga mengtzeana (Saxifragaceae)

Published: November 2022

In the Flora of China account (Pan et al. 2001) of Saxifraga mengtzeana
Engl. & Irmsch., eight synonyms were attributed to it and one variant,
recognised as S. epiphylla Gornall & Ohba, was split from it. This
study re-evaluates the taxonomic status of some of the synonyms and of
the segregated species in the light of new evidence presented here.
Morphological and molecular evidence demonstrate that populations from
north-western Yunnan and Sichuan are genetically differentiated from
those in south-eastern Yunnan and neighbouring Guangxi. Observations in
the field and in cultivation show that the peltate petiole attachment
diagnostic of S. mengtzeana var. peltifolia Engl. & Irmsch. is
developmentally labile. Similar observations combined with molecular
data show that viviparous phenotypes, formerly treated as S. epiphylla,
although largely under genetic control, occur sporadically throughout
the ranges of both northern and southern taxa. Populations from
north-western Yunnan and Sichuan are best recognised as S. geifolia
Balf.f., whereas those from south-eastern Yunnan and neighbouring
Guangxi are S. mengtzeana. Peltate-leaved variants of the latter are
given no status and are relegated to complete synonymy. Viviparous
phenotypes of S. mengtzeana are demoted to the rank of forma, as f.
epiphylla; analogous phenotypes of S. geifolia are newly described as f.
vivipara. Keywords China, Saxifragaceae, Phylogeny, Morphology, Taxonomy

Securing Critical National Infrastructure Against Hacktivist
Authors:   School of Technology Ghana Institute of Management & Public Administration  GreenHills, Accra, Ghana, Timothy Kwaku
Published: November 2022

The acts of hacktivists in today's modern world might have extremely negative repercussions for the order and peace of countries. Hacktivists, by the very nature of their methodology, invariably target important government installations. This research focuses mostly on investigating the myriad of approaches that may be taken to cyber-secure important national infrastructure against the maneuvers that can be carried out by hacktivists. Inferences are drawn in this study from hacktivism episodes that occurred in the past and were documented by a variety of sources, some of which may be verified. A four-point cyber security plan for important national infrastructure has been developed as a way to provide direction for the execution of cybersecurity measures by key state facilities. This scheme was inspired by the ideas presented previously. Keywords: Critical National Infrastructure, Security, Hacktivists, Cyberspace, Hacking, Cybercrime

This article advances a retrospective review of Portugal´s role in the European Union, especially within the Common Foreign and Security Policy (CFSP), considering the case analysis of Timor-Leste´s process of independence. The evolution of Portuguese foreign policy is exposed, in its various phases, since the establishment of democracy, an evolution that demonstrates the Europeanization of Portuguese foreign policy and its importance in East Timor’s independence process. This contribution analyses several factors and conditions that led to the resolution of East Timor issue and its link to Portugal’s role within the framework of the CFSP.
A paz enquanto dependência: uma análise da dimensão econômica do processo de reconstrução pós-bélica no Timor-Leste
Authors: de Souza Rocha Fábio , Blanco Ramon
Published: November 2022

The post-war reconstruction process became the main reference for action in favor of peace in the world after the cold war period. In this sense, studying it corresponds to analyzing which vision of peace, applied in a practical way, is dominant in the world from this period onwards. Thus, the objective of this paper is to identify in the post-war reconstruction process of East Timor the economic dimension impacts of the peacebuilding instrument, from the analytical tools of the Marxist Dependency Theory. The hypothesis is that the role of International Financial Institutions in the economic dimension of East Timor peacebuilding was responsible for creating favorable structures to dependence and, consequently, an incompatible scenario with the new UN perception of peace.
A génese da formação das FALINTIL: contributos para a edificação do Estado
Authors: Brás Bernardino Luís Manuel
Published: November 2022

This essay, told in the first person, aims to analyse the transformation process that took place in 2001, between Aileu and Metinaro, when the National Liberation Armed Forces of Timor-Leste (FALINTIL) gave rise to the Defence Forces of Timor-Leste (FDTL). Following the 1999 referendum, in the context of the United Nations Mission (UNTAET), the formation of FALINTIL-FDTL began in 2001 and constituted one of the central pillars for the construction of the Timorese State. This strategy materialised on May 20, 2002, when the independence of East Timor was formally declared, at a time when the Timorese Armed Forces had already assumed their role as guarantors of the Constitution and central elements of the Rule of Law in the pursuit of security and development of the country.
A ascensão eleitoral do Rassemblement National de Marine Le Pen
Authors: Carvalho João
Published: November 2022

In April 2022, Marine Le Pen passed for the second consecutive time to the second round of the presidential elections against the incumbent president Emmanuel Macron. Twenty years early on, her father, Jean-Marie Le Pen, caused a political earthquake at the European level after attaining a similar presence in the second round of the presidential ballot. In comparison to the 17.8 per cent of the vote obtained by Le Pen in the second round, Marine’s electoral support in 2022 more than doubled this figure, as she collected 41.45 per cent of the popular vote in 2022. This trend demonstrated an impressive growth of electoral support of the French far right, which was the party family with most electoral support at the presidential ballot. This research will review the Front National development under Le Pen’s leadership, as well the electoral ascension and political programme of Marine that led to the rebranding of the party into Rassemblement National.
