RED FLAT LICHEN OF THE ORAL MUCOSA IN THE PRACTICE OF A DENTIST-SURGEON
Authors: Kriventsev A. E , Popkov V. S
Published: September 2021

Currently, in the clinical practice of a dentist-surgeon, patients with various diseases, anomalies and deformities in the oral cavity are often found. The red lichen planus (CPL) is not an exception. This paper discusses the main features of the course of the disease in the oral cavity and possible approaches to therapeutic tactics in surgical intervention. Thus, patients with CPL have edema, hyperemia, multiple or single nodular rashes on the oral mucosa (SOPR), enlarged and painful lymph nodes, and discoloration of the gums. Among the main complaints are pain and bleeding in the area of the changed SOPR, which aggravates the process of surgical intervention and creates certain difficulties for the dentist-surgeon. Due to the spread of this disease among people from 30 to 60 years old, who often require dental care, clinicians need and need to have knowledge about this pathology.
‘My Family and I Are Absolutely against This Law’: Gender Citizenship and Domestic Violence in Contemporary Russia
Authors: Muravyeva Marianna
Published: September 2021

The article examines how post-soviet legal initiatives on prevention of intimate partner and domestic violence relate to the concepts of gender citizenship and “new private” which transformed gender order in the Russian Federation. To explore emerging concepts the article focuses on the discursive practices of the public debate on the draft law “On prevention of family-domestic violence,” which was released by the Federation Council for the online public discussion on 29 November 2019 and became the most debated draft law drawing 11,186 online entries as comments. Using grounded theory to identify main discursive clusters of the public debate, the article offers an analysis of how theories of cultural sovereignty and “new private” are articulated in contemporary Russian public space. This analysis, supplemented by the examination of other legal and policy documents on prevention of violence against women, gender policy and human rights of women, resulted in conclusions that in post-soviet Russia the concept of gender citizenship has been developing in the close relationship with the concept of cultural sovereignty, which provides the State with legitimate ways to exercise a selective approach to the guarantees of human rights and reject gender-sensitive legislation on the grounds of protecting the family as a traditional value at the expense of human rights of women.
«It’s Only a Joke!» What is an Offensive Joke among Adolescents?
Authors: Gulyaev Pavel , Titkova Vera , Khodorenko Daria , Tishchenko Dmitry
Published: September 2021

All of us cannot imagine adolescents' daily communication without humor and making fun of each other. Jokes can help strengthen friendships, smooth out the awkwardness, or maintain status in the group, but sometimes jokes become a means of humiliation and bullying. Despite many studies, determining the demarcation line between comic and aggressive words is quite challenging. This border remains uncertain. This paper aims to identify characteristics in which a joke becomes offensive and can develop into bullying.The article presents the results of a qualitative analysis of 72 interviews with middle and high school students. We identify three situations when a joke is perceived as aggression. Firstly, If a fun statement emphasizes the differences between the adolescent and the group, it makes one feel "inferior" compared to peers. Secondly, the difference in statuses between a speaker and an interlocutor exists, leading to no reply to a joke using a joke. In that case, the joke ceases to be a part of the dialogue and becomes a means of reinforcing inequality. Thirdly, if not all participants are aware of "the rules of the game," they cannot understand the context of reading the joke. That means the statement is interpreted in different ways by the parties, leading to resentment. The findings can help design effective bullying prevention measures in the school environment.
Social Provision of Disabled People in Welfare States: the Scope of Social Benefits and Anti-Crisis Regulation. Part 1
Authors: Kulagina Elena
Published: September 2021

The article consists of two separate publications (Part 1 and Part 2) and analyses social security policy towards people with disability at working age in developed welfare states (social-democratic, conservative-corporatist and neoliberal regimes). Part 1 considers various approaches to reformation of state disability assistance aimed at overcoming “dependency culture” and increasing personal responsibility for wellbeing. The analysis is conveyed on the basis of international research as well as statistical data of the EU and OECD for the past 30 years. The article discusses the reasons for the growing assistance demand, the grounds for tightening the requirements for selection standards as well as the approaches to evaluation of disability. Institutional schemes of social welfare and participation conditions are accounted for. The author analyses the approaches to reducing poverty and inequality: redistribution of state expenditures within disability programmes and alternative support schemes offering people with disabilities a wide scope of social benefits based on research data and individual evaluation of health condition.
Life positions in self-regulation of life activity of the youth
Authors: Zubok Yulia A. , Chuprov Vladimir I. , Lyubutov Alexander S. , Sorokin Oleg V.
Published: September 2021

Recently, the topic of the life positions of young people attracts more attention due to the activation of youth in the socio-political space of the society life: defending their right to participate in the formation of urban space, participation in volunteer and environmental movement, for the preservation of cultural heritage and values ​​of a various spectrum: from traditional to modern. The nature of these and other types of activity is regulated by a life position, reflecting the understanding by different groups of young people of themselves, the meaning of their life, their role in society.

The article examines the essence of the life position of youth, the specifics of its formation within the existing semantic space of reality and the relationship with social activity. On the basis of the concept of socio-cultural self-regulation of life activity developed by the Center for Sociology of Youth of the Institute of Socio-Political Research FCTAS RAS and the data obtained in the course of the Center for Sociological Research, the author analyses the connection between the life position of young people and age, the level of material status and education, as well as with regional living conditions.

The interconnection between the life positions of young people and their ideological attitudes towards individualism and collectivism, trust and distrust of others are described. By using structural and taxonomic modeling of the life process of young people, the interrelationships of their life positions with elements of the socio-cultural mechanism of self-regulation are considered. Thus, the author analyzes the connections between the core of the taxon of habitus of active and passive life positions of young people with archetypes, mental traits, modern features and life-meaning values, types of youth cultures. It has been established that the regulatory function of an active life position is realiszed through both traditional and modern elements of the self-regulation mechanism: by archetypes of glory and idealzation of the past, on the one hand, and rationalism, openness to everything foreign, attitude to the country as a place of residence, on the other. In turn, the regulatory function of a passive life position is predominantly formed under the influence of the conditions of the vital activities of the young people, and the role of youth types of culture and life-meaning values ​​is reduced to their awareness of the semantic content of the formed habitual attitude. The article also analyzes the indicators of the social activity of young people based on their connection with the worldview semantic attitudes.

Authors: Sampiev Israpil M.
Published: September 2021

The article analyses a regional university as a social institution on the example of the case of the Ingush State University. A general description of the university is given. It is shown that a regional university in modern conditions as a social institution acquires special significance both as a scientific institution, and as the main element of the regional educational space, and as a center of an innovative economy. The Ingush University focuses on continuing professional education, that includes pre-university training, secondary vocational education, higher vocational education at various levels, as well as postgraduate and additional vocational education. Opportunities for obtaining secondary vocational and higher education for socially vulnerable segments of the population are expanding. The university is one of the largest employers in the region, therefore, the article emphasises its role in solving the problem of graduates employment. The university provides opportunities for stable employment for representatives of the highest qualifications, who otherwise would not have been able to find an occupation due to the peculiarities of the structure of the depressed regional economy. In addition, the conditions for the development of small innovative enterprises are being formed at the Ingush State University. The driving force behind this process is the Engineering Center, a supplier of a sorbent with a high sorption capacity to the Russian market. The centre is aimed at a long-term solution of problems in the development of modified sorption materials that are used in a wide range of industries, including medicine and agronomy, to eliminate environmental pollution as a result of oil spills, to purify wastewater from various organic substances. The culture-creating role of the university in the space of regional culture is multifaceted. The university, on the one hand, is part of the world cultural and educational community, on the other hand, it works to preserve, develop and spread the culture of the regional peoples. The article analyses the integrative function of the university in the creation and support of a single educational and cultural space as an important condition for state unity and sustainable development of our multinational country. The role of the rector's personality in solving the problems facing the regional university in modern conditions is emphasized.
Families facing the Italian lockdown: Temporal adjustments and new caring practices in shared physical custody arrangements
Authors: Merla Laura , Murru Sarah
Published: September 2021

Objective: This paper investigates the impact of the 2020 Covid-19 related Spring Lockdown in Italy on families practicing shared physical custody (SPC) arrangements for their children.

Background: Those family configurations partly challenge the dominant 'mother as main carer model' that characterizes Italian society. Here, we consider the lockdown as a "challenge-trial" to analyze the strategies that these families have developed to cope with lockdown, and to reveal the overarching structures that contributed to shape this experience of lockdown.

Method: We draw on semi-structured interviews with 19 parents (9 fathers and 10 mothers), part of 12 families practicing SPC.

Results: We propose a typology of custody re-organizations during lockdown and how this affected the division of parental involvement based on a) change/no change in sleepover calendars in favor of mother/father; and b) similar/different arrangements for siblings – a new practice that emerged and also has implications for the division of childcare between parents. Four types are identified where we emphasize new parenting practices and the role played by material housing configurations, relations and tensions between family members, as well as balancing work, school and childcare.

Conclusion: We highlight the usefulness of applying a "challenge-trial" lens to the study of family life under lockdown, and the need to complexify research on gender equality in shared parenting and on sibling relationships in post-divorce families.

Published: September 2021

Highlight Research:The potential calorific value of marine debris obtained from calculating the total waste is 12.05 MJ/kg, which still falls within the incinerator application's standard criteria. AbstractMarine debris, a global environmental issue today, is a major threat to Bali’s seas which are famous for its natural beauty and aggravated by the spread of COVID-19 pandemic. This study aimed to determine the characteristics of marine debris in Bali Island, especially in the southern region and to analyze the feasibility of incineration as one of the waste treatment processes. This research was conducted by utilizing secondary data and literature reviews from related previous studies. Water content and caloric value were measured directly using the ASTM E 790-15 and ASTM D 5865-11a standards. Marine debris generation from 2013 to 2019 tends to decrease from 1.22 kg/km.day to 0.46 kg/km.day. Organic waste (59.4%) comprised the largest marine debris followed by plastic waste (13.4%) and diapers (11.9%). Thermal technology such as incineration can be introduced to treat marine debris. The standard application of incinerator technology is moisture content and caloric value. The water content of marine debris is reportedly 54.56%, therefore, further preliminary processing is needed, especially for waste with high moisture content, such as diapers and organic waste. The potential calorific value of marine debris during the COVID-19 pandemic obtained from calculating the total waste was 12.05 MJ/kg which still did not meet the incinerator application's standard criteria.

Highlight ResearchThe Set Net was identified and recorded.Length and weight of the catch of set net was analyzed. AbstractSet net fisheries are made according to traditional fishing gears method in the coastal waters of Sungai Sembilang, Selangor, Peninsular Malaysia. These fisheries system are the passive structure of gear used to catch fish that swim in shallow water with muddy substrate. This study focused on determining the species variety and the possible future of set net fisheries in Sungai Sembilang. Catch composition of set net was investigated based on the catch data during July to December 2020 and continued from January to February 2021. The catch data was recorded by a research assistant on site during fishing season. The data consist of species, length and weight of all catches recorded. Total catch of 60 fish species belonging to 23 families were captured during this study period. Ariidae (31.73%), Clupeidae (11.56%), and Scatophagidae (7.96%) were determined as dominant families caught this set net. The total dominant catch amount of species Plicofollis argyropleuron (18.71%), Nemapteryx caelata (9.96%), and Anodontostoma chacunda (8.92%) compromised 37.6% of the total catch. This type of fishing gear can be used by local fisherman to catch fishes and can prevent trawl net from come closer to the shore. This study would provide some general useful information about the status of set net fisheries as well as the species abundance caught from the set net.

Despoliated Ecosystem and the Exploited Woman: Victims or Volunteers? A Reading of Kaine Agary’s Yellow-Yellow
Authors: Ohagwam Uchenna
Published: September 2021

The horrendous situation in the Niger Delta region of Nigeria is gradually producing a rich and enduring literature, which paints a vivid picture of the trauma of living in that part of the world. Playwrights, poets, dramatists and literary critics have all lent their contributions in a determined effort at speaking up against the enormity of the environmental degradation in the region; a tragedy brought about by the insensitive exploitation of the region’s natural resources by multinational oil corporations. This study seeks to examine Kaine Agary’s perspective towards the problem as captured in her fictional work, Yellow-Yellow, with focus on the heavy toll it takes on the woman. The dilemma of being caught in the web of either a victim or a volunteer, compels the woman to either dependency or independence. Thus, the paper concludes by making a case for economic independence and argues that it is the surest security for women, especially, the Niger Delta woman.

Linear Buckling Analysis Considering No-compression Property of Metal Grid Shells Stiffened by Tension Braces
Authors: Yamamoto Kenji , Utebi Hayato
Published: September 2021

In order to analyze the buckling behavior of lattice shells stiffened by cables or slender braces without pre-tension, it is necessary to consider the no-compression property of braces. This paper proposes an innovative method of linear buckling analysis that considers the no-compression
property of braces. Moreover, in order to examine the proposed method's validity, its results are compared with the results from a nonlinear buckling analysis with geometrical nonlinearity and material nonlinearity to express the no-compression property of braces. The results show that the
proposed method can well-predict the buckling behaviors of lattice shells stiffened by tension braces.
Modified Gravity and Dark Matter
Authors: Abbas Syed , Akhtar Nasim , Alam Danish
Published: September 2021

At present there is a renewed interest in theories of ”modified” gravity. Here, under a more drastic modification enforced by Galilei group, we obtain a completely new gravitational structure, and which exists in addition to the already available general relativity of today. Correlated with this, we show that in addition, there is a new ”modified” quantum mechanics, in as much as it exists as an independent and new ”pure” non-relativistic quantum me- chanics, and which has no relativistic counterpart. This is in addition to the present quantum mechanics, where the relativistic and non-relativistic structures are counterparts of each other. The above holds, firstly due to the correlation between Galilei group and quantum mechanics. These math- ematical conclusions are consolidated by the fact that there exists a physical Majorana interaction between each neutron- proton pairs in nuclei. Galilei invariance of Majorana exchange in Majorana interaction, shows that the mass here is of pure gravitational nature, and which is immune to the other three forces. This makes an amazing connection between the gravitational force and the quantum mechanics. This pure gravitational mass would man- ifest itself as dark matter of the universe. It is our new modified gravity that generates the dark matter.
Prehispanic Foods Oyster Mushroom (Pleurotus ostreatus), Nopal (Opuntia ficus-indica) and Amaranth (Amaranthus sp.) as New Alternative Ingredients for Developing Functional Cookies

Published: September 2021

Oyster mushroom (Pleurotus ostreatus), nopal (Opuntia ficus-indica) and amaranth (Amaranthus spp.) are pre-hispanic foods widely consumed in Mexico. However, there are no standard products developed with these ingredients as functional cookies. This study evaluated the impact of partial replacement (50%) of whole-wheat flour (WWF) with three formulations of P. ostreatus, nopal and amaranth flours (POF, NF and AF, respectively) in the nutritional/antioxidant properties of fortified cookies. The proportion of flours´ ingredients (WWF:AF:NF:POF) were 100% WWF (traditional cookies), 50:35:10:5 (formulation 1), 50:30:15:5 (formulation 2) and 50:40:5:5 (formulation 3). Proximal composition, phenolic/flavonoid contents, and ABTS+ scavenging activity were determined in flours and cookies. POF, NF and AF possess a high nutritional value comprising polyphenols/flavonoids and a significant antioxidant potential. Total protein, ashes and flavonoids were higher in fortified cookies than controls. Cookies prepared with Formulation 2 -highest nopal level- contained 5.29% of dietary fiber and 5-times higher polyphenol content than control cookies. The ABTS+ scavenging ability was similar in the three enriched cookies (87.73-89.58%) but higher than traditional cookies (75.60%). Applicability of POF/NF/AF for replacing up to 50% of WWF in production of functional cookies was demonstrated. The research promotes renewable local bioresouces for a sustainable agri-food chain, especially edible mushrooms.
Measurement of Adult Human Brain Responses to Breath Holding by Multi-Distance Hyperspectral Near-Infrared Spectroscopy
Authors: Guerouah Zahida , Lin Steve , Toronov Vladislav
Published: September 2021

A major limitation of near-infrared spectroscopy (NIRS) is its high sensitivity to the scalp and low sensitivity to the brain of adult humans. In the present work we use multi-distance hyperspectral NIRS (hNIRS) to investigate the optimal source-detector distances, range of wavelengths, and analysis techniques to separate cerebral responses to 30-s breath holds (BHs) from the responses in the superficial tissue layer in healthy adult humans. We observed significant responses to BHs in the scalp hemodynamics. Cerebral responses to BHs were detected in the cytochrome C oxidase redox (rCCO) at 4 cm without using data from the short-distance channel. Using the data from the 1 cm channel in the two-layer regression algorithm showed that hemodynamic and rCCO responses also occurred at 3cm. We found that the waveband 700-900 nm was optimal for the detection of cerebral responses to BHs in adults.

Published: September 2021

The article is devoted to issues related to the propagation and transformation of vortexes in the optical range of frequency. Within the framework of the traditional and modified model of slowly varying envelope approximation (SVEA), the process of converting vortex beams of the optical domain into vortex beams of the terahertz radio range based on nonlinear generation of a difference frequency in a medium with a second-order susceptibility is considered. The modified SVEA splits a slowly varying amplitude into two factors, which makes it possible to more accurately describe the three-wave mixing process. The theoretical substantiation of the rule of vortex beams topological charges conversion is given – the topological charge of the output radio-vortex beam is equal to the difference between the topological charges of the input optical vortex beams. A numerical simulation model of the processes under consideration has been implemented and analyzed.
Note on the Charged Black Hole Solutions in a Static Quantum Inspired Spacetime: Massive Gravity as Background
Authors: Aounallah Houcine , Zarei Hayade , Rudra Prabir , Majumder Barun
Published: September 2021

In this paper, we explore the black hole solutions with rainbow deformed metric in the presence of exponential form of nonlinear electrodynamics with asymptotic Reissner-Nordstrom properties. We calculate the exact solution of metric function and explore the geometrical prop- erties in the background of massive gravity. From the obtained solution, the existence of the singularity is confirmed in proper limits. Using the solutions we also investigate the thermody- namic properties of the solutions by checking the validity of the first law of thermodynamics. Continuing the thermodynamic study, we investigate the conditions under which the system is thermally stable from the heat capacity and the Gibbs free energy. We also discuss the possible phase transition and the criticality of the system. It was found that the quantum gravitational effects of gravity’s rainbow render the thermodynamic system stable in the vicinity of the singu- larity. From the equation of state it was found that after diverging at the singularity, the system evolves asymptotically into pressure-less dust as one moves away from the central singularity.
Sagacious Epitope Selection for Vaccines, and Both Antibody-Based Therapeutics and Diagnostics: Tips From Virology and Oncology
Authors: Gan Samuel Ken-En , Phua Ser-Xian , Yeo Joshua Yi
Published: September 2021

The target of an antibody plays a significant role in the success of antibody-based therapeutics and diagnostics, and to an extent, that of vaccine development. This importance is focussed on the target binding site – epitope, that sagacious epitope selection in a form of design thinking beyond traditional antigen selection using whole cell or whole protein immunisation can positively improve success. Intrinsic factors that can affect the functioning of resulting antibodies can be more easily selected for with purified recombinant protein production and peptide synthesis to display limited/selected epitopes. Many of these factors stem from the location of the epitope that can affect the accessibility of the antibody to the epitope at a cellular or molecular level, direct inhibition of target antigen activity, conservation of function despite escape mutations, and even non-competitive inhibition sites. Through the incorporation of novel computational methods for predicting antigen changes to model-informed drug design development, superior vaccines and antibody-based therapeutics or diagnostics can now be more easily designed, mitigating failures. With detailed examples, this review highlights the new opportunities, factors and methods of predicting antigenic changes for consideration in sagacious epitope selection.
Protein Structure, Models of Sequence Evolution, and Data Type Effects in Phylogenetic Analyses of Mitochondrial Data: A Case Study in Birds
Authors: Gordon Emily L. , Kimball Rebecca T. , Braun Edward L.
Published: September 2021

Phylogenomic analyses have revolutionized the study of biodiversity, but they have revealed that estimated tree topologies can depend, at least in part, on the subset of the genome that is analyzed. For example, estimates of trees for avian orders differ if protein coding or non-coding data are analyzed. The bird tree is a good study system because the historical signal for relationships among orders is very weak, which should permit subtle non-historical signals to be identified, while monophyly of orders is strongly corroborated, allowing identification of strong non-historical signals. Hydrophobic amino acids in mitochondrially-encoded proteins, which are expected to be found in transmembrane helices, have been hypothesized to be associated with non-historical signals. We tested this hypothesis by comparing the evolution of transmembrane helices and extramembrane segments of mitochondrial proteins from 420 bird species, sampled from most avian orders. We estimated amino acids exchangeabilities for both structural environments and assessed the performance of phylogenetic analysis using each data type. We compared those relative exchangeabilities with values calculated using a substitution dataset for transmembrane helices from a variety of sampled set of nuclear- and mitochondrially-encoded proteins, allowing us to compare the bird-specific mitochondrial models with a general model of transmembrane protein evolution. To complement our amino acid analyses, we examined the impact of protein structure on patterns of nucleotide evolution. Models of transmembrane and extramembrane sequence evolution for amino acids and nucleotides exhibited striking differences, but there was no evidence for strong topological data type effects. However, incorporating protein structure into analyses of mitochondrially-encoded proteins improved model fit. Thus, we believe that considering protein structure will improve analyses of mitogenomic data, both in birds and in other taxa.

The prediction performance of numerical models of tsunami wave pressure on land structures was investigated using blind tests. Two types of numerical models were used, based on the volume-of-fluid (VOF) method. Both models reproduced the experimental results well for water-level time series. For wave-pressure time series, some differences were observed between the two models in the vertical distribution of wave pressure during the initial rise. In both models, however, the experimental results showed that overall trends for total wave force were in good agreement. The experimental results produced a value slightly higher than the maximum wave force, suggesting that caution is needed when designing structures to ensure that wave force is not underestimated.

In the New Courses of Study revised in March 2017, the contents of safety education, including disaster prevention, were significantly enhanced compared with the previous Courses of Study (2008). This can be attributed to the 2011 Great East Japan Earthquake and an increase in the frequency of subsequent natural disasters, as well as changes in the education curriculum stipulated by the Courses of Study, such as the introduction of active learning. Associated with this change, in the field of education, contents that conform to the curriculum of each subject are required. In this research, we first focus on how the contents of the Courses of Study related to disaster prevention have changed in recent years, and discuss what drove the change. In addition, we classify and analyze, in terms of elementary schools, the system of the educational contents related to disaster prevention included in the New Courses of Study. By visualizing the contents of our classification and analysis, we indicate the scope of disaster prevention covered by the New Courses of Study in the field of disaster prevention. Subsequently, we propose ways to manage the scope of disaster prevention in disaster prevention learning in consideration of the comprehensiveness to address the problem.
Determination of residual low-order detonation particle characteristics from IMX-104 mortar rounds
Authors: Bigl Matthew , Beal Samuel , Ramsey Charles
Published: September 2021

The environmental fate and transport of energetic compounds on military training ranges are largely controlled by the particle characteristics of low-order detonations. This study demonstrated a method of command detonation, field sampling, laboratory processing, and analysis techniques for characterizing low-order detonation particles from 60 mm and 81 mm mortar rounds containing the insensitive munition formulation IMX-104. Particles deposited from three rounds of each caliber were comprehensively sampled and characterized for particle size, energetic purity, and morphology. The 60 mm rounds were command-detonated low order consistently (seven low-order detonations of seven tested rounds), with con-sumption efficiencies of 62%–80% (n = 3). The 81 mm rounds detonated low order inconsistently (three low-order detonations of ten tested rounds), possibly because the rounds were sourced from manufacturing test runs. These rounds had lower consumption efficiencies of 39%–64% (n = 3). Particle-size distributions showed significant variability between munition calibers, between rounds of the same caliber, and with distance from the detonation point. The study reviewed command-detonation configurations, particle transfer losses during sampling and particle-size analysis, and variations in the energetic purity of recovered particles. Overall, this study demonstrated the successful characterization of IMX-104 low-order detonation particles from command detonation to analysis.
Alternative analysis for construction progress data spatial visualization
Authors: Boone Jonathan , Sells Bobby , Davis Matthew , McDonald Dan
Published: September 2021

The U.S. Army Corps of Engineers (USACE) construction projects have multiple stakeholders that collaborate with project delivery team members during the execution of these projects. Many of these stakeholders are located across the U.S., which makes virtual interactions a common communication method for these teams. These interactions often lack spatial visualization, which can add complications to the progress reports provided and how the information is received/interpreted. The visualization of project progress and documents would be invaluable to the stakeholders on critical projects constructed by the USACE. This research was conducted to determine alternatives for migrating Resident Management System (RMS) data into a portal web viewer. This report provides proposed solutions to creating these links in efforts to better harmonize data management and improve project presentation.

Unconformity-bounded sequences within the Miocene strata of the Suez Rift reflect a complex interplay between tectonism and sea level fluctuations. Analyses of Miocene outcrops along the Sinai margin of the Gulf of Suez provide new insights into the sequence stratigraphy of this basin. The Miocene strata can be subdivided into seven major sequences separated by biostratigraphically defined time breaks. These lacunae represent depositional sequence boundaries, transgressive surfaces and condensed sections. These basinwide time breaks were related to major tectonic events from rift initiation through rift climax, and post-rift stages. These events include regional sag and fault initiation, fault linkage, footwall uplift, shallowing of detachment depths and increased fault block rotations, regional isostatic uplift, and thermal subsidence. Superimposed on this complex structural evolution were Miocene sea level fluctuations of a magnitude of several tens of meters to a hundred meters. The Sinai outcrops expose the four oldest Miocene biostratigraphic sequences which correspond to two depositional sequences. The lower sequence consists of the Nukhul Formation which was deposited during a transgression (with the higher frequency events recorded as local erosional surfaces, flooding surfaces, and ravinements) and the Mheiherrat Formation which was deposited during a relative high stand. The upper sequence includes the Asl Formation which was deposited during a low stand and the Ras Budran Member of the Ayun Musa Formation which was deposited during the ensuing high stand.

Background: The outbreak of the COVID-19 pandemic has caused extensive public health concerns, posing significant challenges to healthcare services. One particular area of concern is the mental health of psychiatric patients, who are often a neglected group. The aim of this study was to investigate the prevalence of, and associated factors for symptoms of post-traumatic stress disorder (PTSD) among psychiatric patients in China during the COVID-19 pandemic. Methods: Self-reported questionnaires were distributed to patients in four psychiatric hospitals in Beijing, China, between April 28th and May 30th, 2020. Information regarding sociodemographic characteristics, COVID-19 related factors, support, psychosomatic factors, and PTSD symptoms was collected data using a series of scales, such as the Impact of Event Scale-Revised, the 7-item Generalized Anxiety Disorder Scale, the 9-item Patient Health Questionnaire depression scale, and so on. Multivariate regression was used to identify factors related to PTSD symptoms. Results: A total of 1,055 psychiatric patients were included in the final sample. The prevalence of PTSD symptoms was 41.3%. Hierarchical linear regression demonstrated that fear of the pandemic and anxiety were shared associated factors for both symptoms of PTSD and its subscales. Additionally, age was an associated factor for the total PTSD (β = 0.12, p < 0.01), intrusion (β = 0.18, p < 0.001), and avoidance (β = 0.1, p < 0.05) symptoms; depression was an associated factor for the total PTSD s (β = 0.13, p < 0.001), intrusion (β = 0.11, p < 0.01), and hyperarousal (β = 0.19, p < 0.001) symptoms. Conclusions: The prevalence of PTSD symptoms was high among psychiatric patients during the COVID-19 pandemic in China. This study found that age, fear of the pandemic, anxiety and depression are significant associated factors of PTSD symptoms in psychiatric patients during the pandemic. We call for higher awareness and introduction of PTSD interventions to relieve the psychological stress in these patients.
Blockchain Leveraged Cyberbullying Preventing framework

Published: September 2021

The popularity of social media has exploded worldwide over the last few decades and becomes the most preferred mode of social interaction. The internet also provides a new platform through which adolescents are being bullied. Appropriate means of cyberbullying detection is still partial and in some cases very limited. Moreover, research on cyberbullying detection extensively focuses on surveys and its psychological impacts on victims. However, prevention has not been widely addressed. To bridge the gap, this paper aims to detect cyberbullying efficiently. This paper employs a standard machine learning method and natural language processing technique as a part of the detection process in decentralized Blockchain leveraged architecture. We provide a fog based architecture for cyberbullying detection, aiming at relieving the server's load by placing the detection and the prevention of cyberbullying processes at the fog layer. The proposal might offer a probable solution to save users, particularly adolescents from severe consequences of cyberbullying.

BackgroundThis study aims to examine the biomechanical influence of residual varus and valgus deformity after malunion of distal femoral fractures on the knee joint. MethodsWe selected 14 adult cadaver specimens to establish the femoral fractures models and subsequently fixed them at neutral position and malunion positions, i.e. at 3°, 7° and 10° at valgus and varus positions, respectively. Ultra-low pressure sensitive film technology was used to quantitatively measure the stress distribution on the medial and lateral plateau of the tibia.ResultsAt neutral position, with 400 N vertical load applied, the stress values of the medial and lateral plateau of tibia were 1.162±0.114 MPa and 1.103±0.144 MPa, respectively. Compared with those measured at neutral position, the stress on the medial plateau of the valgus tibia significantly increased, while that on the lateral plateau of the valgus tibia significantly decreased (both P<0.05). In contrast, the stress on the lateral plateau of the valgus tibia significantly increased, while that on the medial plateau of the valgus tibia significantly decreased (both P<0.05). The medial plateau of tibia demonstrated significantly higher stress values than those on the lateral plateau at neutral position and 3°, 7°, 10° varus deformities, respectively (all P<0.05), but showed significantly lower values than the those on the lateral plateau at 3°, 7°, 10° valgus deformities, respectively (all P<0.05). Conclusions﻿The residual varus and valgus deformities after mulunion of the distal femoral fracture resulted in significant changes of the stress distribution of the knee joint. Anatomical reduction and firm fixation of distal femoral fracture should be as possible to be obtained to avoid possible varus and valgus deformities.
