Risk Management Strategies in the Ancient Agricultural Society
Authors:   Korean Ancient Historical Society, Lee Huikyung
Published: September 2022

In the Proto-Three Kingdoms period, as the characteristics of an intensive agricultural society emerged, new types of risk management strategies were expected to emerge and differ according to regional conditions. In this paper, various types of archaeological data were analyzed to identify risk management strategies related to risk prevention, self-assumption, and pooling. First, the types and quantities of crop and livestock remains were analyzed to identify risk prevention strategies such as diversification and the use of environmentally sensitive species, and second, wild animal and plant remains and hunting-related tools were analyzed to identify risk prevention strategies based on food diversification. Lastly, the third attempt was to reveal risk self-assumption and pooling strategies through analysis of storage patterns.
As a result of the analysis of archaeological data, it was found that in the central region of the Proto-Three Kingdoms period, various foods were used as possible, and millet with low environmental sensitivity were mainly cultivated to prevent risk, and risk was assumed and shared with limited storage pooling strategies. Differences between regions or sites were observed in detail in risk prevention strategies such as crop diversity, the proportion of hunter-gathering, and the proportion of broomcorn millet and Barnyard millet with different environmental sensitivity, and it was estimated that these differences were affected by environmental conditions. The risk management strategy, which appeared in the central region of the Proto-Three Kingdoms period, was thought to show that maintaining a stable subsistence was important rather than taking risks to obtain high profits.
A Critical Review of the Chronology of the Bangudae Petroglyphs in Korea
Authors:   Korean Ancient Historical Society, Kang Bong Won
Published: September 2022

The objective of this paper is to reexamine the chronology of the Bangudae petroglyphs established in 1980 and generate a new chronology. This paper argued that the chronology of the rock art should be dated to the ‘Neolithic.’ According to the old chronology of the Bangudae rock art formulated in 1980, the date ranges between the Korean Bronze and Early Iron Ages (BC 300-100 AD). This chronology is still playing a critical role in Korean archaeological and historical societies and supported by a number of rock art researchers.
In particular, since the Korean National History text books are adopting the old chronology, almost all the Korean students have been significantly influenced by it. In the mean time, various material evidence discovered at different archaeological sites suggests that the rock art may have been engraved much earlier than ‘the Bronze and Early Iron Ages.’ Based on newly collected materials, many researchers have been arguing that the rock art may have been manufactured during the Korean Neolithic (ca. 4000-3000 BC).
This paper pointed out some problems that the old chronology has and focused on a few variables and archaeological context necessary to formulate a new chronology of the Bangudae petroglyphs. This paper emphasized the importance of the interpretation and appropriate archaeological explanation of the motifs in which we are interested. To testify the new date of the rock art, ecofact and artifacts such as whale bone, whaling gears, oceangoing vessels and oars, obsidian discovered in Ulsan and southeastern part of Korean peninsula were examined in conjunction with archaeological context. This paper focused on the subsistence patterns and frequency of shell midden of both the Neolithic and Bronze Ages, hunting-fishing and stone tools related to agricultural practices.

Published: September 2022

Background: Postmenopausal bleeding is bleeding from the genital tract one year after menopause. The incidence is 4-11%. It is one of the cardinal signs of endometrial carcinoma. There is 10% risk of genital cancer and 10% risk of significant pathology and needs evaluation. In majority of them, it is due to benign condition such as endometrial atrophy or polyp. The aim of the present study was to evaluate the endometrial thickness by transvaginal ultrasound and to correlate with the histopathological pattern of the material obtained by hysteroscopic guided biopsy or curettage.Methods: A retrospective analysis of all the patients attending the outpatient department from January 2017 to December 2019 was done. This study was undertaken at M.S. Ramaiah Medical College and Hospitals. All patients with postmenopausal bleeding were evaluated clinically, then they underwent PAP smear, transvaginal ultrasound for endometrial thickness. This was followed by hysteroscopic guided biopsy and curettage. The material obtained was sent for histopathological examination as it is the gold standard for further management.Results: A total of 89 patients were enrolled for the study. The final results revealed atrophic endometrium in 35.95%, hyperplasia without atypia in 20.2%, polyps in 11.2% and endometrial carcinoma in 6.7%.Conclusions: In postmenopausal bleeding assessing endometrial thickness by transvaginal ultrasound is ideal. Hysteroscopy is a simple technique to evaluate the uterine cavity and take biopsy for histopathological examination, which is the gold standard.

Authors: Vijan Tanya S. , Mane Suwarna , Kumar Sushil
Published: September 2022

Background: Anaemia is a major public health problem worldwide. Haemoglobin (Hb) cut-off in anaemia should be taken as 11 gm/dl in the first and third trimester and 10.5 gm/dl in the second trimester, and a post-partum Hb of 10.0 gm/dl. The aim of the study is to compare the efficacy of iron-sucrose versus ferric carboxymaltose (FCM) in the treatment of postpartum anaemia.Methods: A prospective randomized interventional study of 132 post-partum females was conducted at a tertiary care hospital, over a 6-month period. Post-partum females delivered via normal vaginal delivery or caesarean section with Hb levels of above 7 gm/dl and below 9.9 gm/dl were randomized into 2 groups. Iron deficit calculated, in mg, according to Ganzoni’s formula. One group received intravenous FCM – 500 mg in 250 ml normal saline (NS) over 30 minutes and the other received intravenous iron sucrose - each ampoule containing 200 mg in 100 ml NS over 30 minutes up to a maximum dose of 1000 mg. Follow up done after 15 days, 4 weeks and 6 weeks. The data was tabulated and compared using statistical analysis.Results: At a 4 and 6 weeks follow up, the mean rise in hemoglobin (Hb) of group A (1.4 g/dl) was significantly greater than that of group B (0.89 g/dl).Conclusions: The study concludes that thought efficacy of drugs is similar, injection FCM shows a prompt rise in Hb, allows a higher dose to be dispensed in a single seating and is more significant in improving quality of life over a period of time even though it has a marginally higher cost.

Published: September 2022

Breastfeeding is the natural way of feeding a new-born. The COVID-19 scenario makes breastfeeding more challenging than usual periods. This study aimed to describe the breastfeeding experiences of mothers with COVID-19 infection. Qualitative data were collected from thirteen COVID-19-infected immediate postnatal mothers through google form questionnaires and in-depth interviews. The COVID-19 infected mothers faced difficulties in feeding their babies. Some of the mothers couldn’t be fed colostrum. Severe stress, lack of family and professional support, COVID-19 infection, and inadequate breastmilk production are the hindering factors affecting the breastfeeding habit of mothers. The main breastfeeding problems are apprehension of spreading the infection to the baby, physical separation due to COVID-19 infection, difficulty in latching, and reluctance to breastfeed after formula feeding. Even though there are lots of problems in breastfeeding among mothers and babies, breastfeeding must be initiated and maintained for the benefit of the mother and baby.

Published: September 2022

A collision tumor is the co-existence of two adjoining but histologically distinct tumors without histological admixture in the same tissue or organ. The most common histological combination of collision tumor in the ovary is the coexistence of mature teratoma with mucinous cystadenomas. The incidence of adnexal mass in pregnancy is 0.05-2.4% of which 94-99% are benign. The 1-6% maybe malignant requiring more extensive surgical procedures that increases likelihood of pregnancy loss. Ovarian tumors first diagnosed during pregnancy often present a challenge for diagnosis and management. Hence accurate knowledge of tumor characteristics, especially the ultrasound appearance and gestational age at diagnosis, are the key prerequisites for establishing the most effective plan of management for the pregnant women. To the best of our knowledge this report of huge collision tumor with successful pregnancy outcome is first of its kind.

Background: GISTs are rare abdominal tumors, encountered as the most common mesenchymal neoplasms of the gastrointestinal (GI) tract leading to GI bleeding. We report a changing trend of diagnosis and management in Indian patients.Methods: The retrospective data was collected from medical records and 62 cases of GIST from 2003 to 2020 in General surgical unit of BHU. They were divided in three groups. In group A (36) patients only surgery, group B (14) patients surgery than adjuvant chemotherapy and in group C (12) who received neoadjuvant chemotherapy then surgery. Preoperatively, USG and CT scans of the abdomen were the main investigations, others being upper gastrointestinal endoscopy and chest x-ray confirm by histopathological and immunohistochemical evaluation.Results: The mean age at presentation was 42.8 years (range 17-74 years) and mean duration of symptoms was of 5 months (range 10 days-2 years). It was from the stomach, (06) duodenum (14) jejunum, (06) ileum, (1) caecum and (4) from the mesentery and (4) from retroperitoneum. 44 cases had low grade benign tumors and 18 malignancies. In group A, 22 (61%) patients showed recurrence in group B, 06, (42%) patients showed recurrence and group C, 02 (33%) patient showed recurrence.Conclusions: Most of the tumours were benign and surgical resection is the mainstay of treatment. However, the patients in which only surgery was done showed maximum recurrence and patients who received neoadjuvant chemotherapy then surgery followed adjuvant chemotherapy showed minimum recurrence.

Published: September 2022

Background: The best ethically acceptable source of cadavers for dissection by medical students is voluntarily donated bodies of people during their lifetime. The main objective of this research was to study the knowledge and attitude of medical students towards body donation.Methods: This was a cross-sectional study involving undergraduate students from a medical institute of Delhi. Sample size of 281 was calculated by taking estimated prevalence of knowledge about the concept of body donation as 88%, 99% confidence interval and 5% sample error. Participants were randomly selected from each year by using random number tables. Data collection was done by using a pre-designed pre-tested semi-structured questionnaire. Data entry and analysis was done by using SPSS version 20 software.Results: The overall knowledge about body donation among medical students was found be poor in many aspects. Their feelings regarding body donation were mostly positive but only a small proportion (22%) were willing to do so, main reasons for unwillingness being disrespectful behaviour towards cadavers (39.7%), lack of approval by family (34.6%), not being comfortable (33.8%) and religious beliefs (18.4%). Higher levels of knowledge were found in females, but a more positive attitude was found in males and those studying in earlier years of graduation (p<0.05).Conclusions: Medical students were found to have poor knowledge about body donation with higher level of knowledge among females. Despite having positive feelings towards body donation, majority were not willing to do so.
A comprehensive review on the role of yoga in the management of type- 2 diabetes mellitus and its benefits over physical exercise in type 2 DM
Authors: Alla Deekshitha , Santhosha Mrudula Alla Sai
Published: September 2022

Diabetes mellitus (DM) is a chronic metabolic disorder characterized by hyperglycemia. It is caused either due to defective secretion of insulin or due to increased insulin resistance of peripheral tissue. The incidence of DM has increased in past decade due to sedentary lifestyle, altered dietary patterns, obesity etc. DM increases morbidity and mortality of individuals, thereby requiring great attention. In recent era, insulin and oral hypoglycemic agents are used in majority to treat DM. Recent studies have shown that simple lifestyle changes like dietary changes, yoga and physical exercise are highly beneficial in reducing the burden of disease. This review focusses on yoga as an intervention in reducing the morbidity from the disease. It highlights the benefits of yoga over physical exercise in halting the progress of disease. Physical exercise is not feasible in patients with obesity, cardio vascular diseases and older age group. Yoga is a physical, psychological and spiritual intervention that is more feasible than physical exercise.
Proptech in Latin America and the Caribbean: How Technology Can Help Reduce the Housing Deficit

Published: September 2022

Recognizing the widespread concern that disruptions created by technology have not yet benefited middle- and low-income households, this study explores the potential of PropTech to positively impact the housing challenges in the region, with a particular focus on the poor or vulnerable populations. This study reveals several emerging trends that offer insight to those thinking about digital transformation in the housing and real estate sector for Latin America and the Caribbean and serve as the foundation for more research. PropTech startups are defined broadly as fast-growing actors that are developing technology-based business models for housing real estate markets. This includes companies operating on most phases of the housing value chain, from the housing units supply side (land, construction, access to services, and home improvement) to the demand side (financing, renting, buying, selling, and commercializing units). PropTech startups mainly address two key issues in the traditional real estate market: lack of transparency and processes inefficiencies. Reducing costs and making information available equalizes the markets playing field. The opportunity for PropTech startups to develop business models that cover lower income brackets is still largely unexplored. Currently, profitable businesses are mostly serving high-income bracket groups. Thus, large-scale solutions that would make investing in the low-income segment profitable remain an opportunity for PropTech companies to target. Also, opportunities remain for startups to explore housing solutions that strengthen adaptation to climate change and curb harmful environmental impact through technology innovations through retrofitting efforts or the repurposing of existing units. The report pays special attention to the different links in the value chain and highlights success stories that are having an impact on the current housing market, resulting in a snapshot of scalable, private-sector-led solutions currently deployed to solve pressing housing problems in the region.

Published: September 2022

The Inter-American Development Bank (IDB) was founded in 1959 as an initiative of Latin American and Caribbean (LAC) countries and the United States to support the development of the region through an institution in which LAC countries would play a leading role through their majority capital and voting shares but with significant participation of the United States. The Agreement Establishing the Inter-American Development Bank (the Agreement; IDB 1959/1996) articulated the desired balance of responsibilities and power between LAC and the United States. It also provided that the IDB's governance would center around three governing bodies: the Board of Governors (BOG), the Board of Executive Directors (EXD), and Senior Management. The objective of this evaluation, requested by the EXD, was to assess the extent to which existing institutional arrangements at the IDB allow it to operate effectively and efficiently while providing sufficient accountability, transparency, and stakeholder voice in decision making. The evaluation focused on four dimensions: (1) effectiveness--the extent to which the IDB's governance arrangements allow the institution to effectively set strategic objectives, provide means to attain those objectives, and monitor performance; (2) efficiency--the degree to which the costs (in both money and time) of the IDB's governing bodies to perform their assigned roles and responsibilities are consistent with their priorities; (3) accountability and transparency--the extent to which the IDB's governance arrangements render the IDB governing bodies accountable to its shareholders for the responsibilities delegated to them, and the ability of secondary stakeholders, such as civil society, project beneficiaries, and private sector entities, to access information; and (4) voice--the extent to which the IDB's governance arrangements provide the shareholders and secondary stakeholders with an adequate voice in decision making.

Published: September 2022

This paper addresses a problem of false positive detection filtering in surveillance video streams. We propose two methods. The first one is based on automatic hard negative mining from a video stream, which is then used for fine-tuning of the baseline detector. The second one is the detector output filtering by analyzing the frequency of detection of visually similar samples. We demonstrate the proposed methods on cascade-based detectors, but they can be applied to any detector that can be trained in a reasonable amount of time. Experimental results show that the proposed methods improve both the precision and recall rate, as well as reducing the computational time by 47%.

The virtual self-image acts not only as a significant element of interpersonal interaction. It also plays a crucial role in the self-determination and self-categorization of the user in his environment. The virtual self-image performs the most important function of a filter and repeater of external influences, including negative ones. The purpose of the article is to identify the relationship between the choice of coping strategies of Internet users and the components of their virtual images. Methodology and methods: the Lazarus-Folkman Coping test and the author's method “Content and structural components of the virtual image of the Internet user's self-image”. Statistical analysis of the data obtained during the study was carried out using the SPSS 26.0 software and the Pearson correlation coefficient. The study involved 80 (n = 80) students of Yakubov Crimean Engineering-Pedagogical University (age from 17 to 26 years, 71% women, 29% men, M = 21.06; SD = 2.54) Results: the coping strategies chosen by the user are reflected in the content and structural components of the virtual self-image.  The prevailing coping strategies of the user are reflected in the content and structural components of the virtual self-image. The confrontational coping strategy has a significant connection with the behavioral (remp = .249) and communicative (remp = .240), reflexive (remp = -.353) components of the virtual self -image; self-control – with visual (remp = .332), behavioral (remp = .573), auditory (remp = .345), and reflexive (remp = .491); social search – with visual (remp = .336), behavioral (remp = .663), rating (remp = .250), auditory (remp = .331) and reflexive (remp = .288); acceptance of responsibility – with behavioral (remp = .444), communicative (remp = .385), auditory (remp = .378) and reflexive (remp = .281); flight-avoidance strategy – with communicative (remp = .482), rating (remp = .241) and auditory (remp = .433); problem solving planning – with behavioral (remp = .294); positive overestimation – with visual (remp = .273), behavioral (remp = .250), auditory (remp = .274). Conclusion: The user constructs their self-presentation in the virtual space based on his preferred strategies of behavior in difficult situations, thereby building long-term protection against threats in real and virtual space.

Political morality of modern Russian youth: values, representations, attitudes
Authors:   Lomonosov Moscow State University, Selezneva Antonina V.
Published: September 2022

In modern socio-humanitarian science, there is a certain lack of research on the moral priorities of young Russian citizens as regulators of their life in the state and society. The study presented in the article was aimed at identifying the political values, ethical representations and attitudes of young people that guide them in assessing the sphere of politics and in their relationships with the state and other political actors. The theo-retical and methodological basis of the study was the political-psychological ap-proach, in which values, ideas and attitudes are considered from psychological posi-tions in the structure of moral and political consciousness. The empirical basis of the study was the materials of the All-Russian questionnaire survey and focus group dis-cussions with young people conducted in 2020-21. The results of the study show that young people consider moral values and norms to be a measure of political relations, albeit a rather relative one. It imposes on politicians the moral demands of sincerity, honesty, work for the benefit of citizens, concern for the public interest. Young peo-ple leave politicians the right to make mistakes, they are ready to forgive politicians for many mistakes, except for those that are associated with a threat to life and health of people and have serious consequences. Young people consider corruption, wars and violence, violation of laws and rights of citizens to be immoral actions in politics themselves. The meaning-forming foundations of the moral assessment of the sphere of politics by young people are the political values of freedom, human rights, justice, security, self-realization. Young people's representations about duty are differentiat-ed: they recognize the duty of a person, but reject the duty of a citizen. Young people are not ready to take responsibility for others, and sometimes for themselves too. They place the responsibility for providing public goods and satisfying their needs on the state. This reflects paternalistic attitudes, traditional for our political culture. The political morality of youth is contradictory and often relativistic.
Meanings deviations of Russian youth at work
Authors:   Institute of Socio-political Research, Branch of the Federal Center of Theoretical  and Applied Sociology of the Russian Academy of Sciences, Sorokin Oleg V.
Published: September 2022

The relevance of the problem of studying the sense deviations of Russian youth at work is due to: changes in the nature of integration of young people at work, on the one hand, and features of self-regulation of deviant behavior of this socio-demographic group in the field of labor relations, on the other. Young people's choice in favour of meanings deviations is seen as a consequence of intensification of the processes of instrumentalization and rationalization of young people at work. These processes are reflected in the growth of social subjectivity of young people through active completion and reconstruction of their social reality. On the basis of empirical data obtained in the course of research by the Center of Sociology of the Youth of ISPR FCTAS RAS, the author analyzes the relationship between the value compo-nents of the image of work, the qualities inherent in the sphere of work and deviant meanings in the cultural space of youth, which allows us to study the sense orienta-tion of self-regulation of deviant behavior of youth in this sphere. The purpose of the analysis is to substantiate the mechanism of self-regulation of the deviant behavior of Russian youth at work. The study of deviant meanings contained in this mechanism makes it possible to determine different types of self-regulation of deviations in the youth environment in the context of the transformation of modern Russian society.
Fault Diagnosis of Rotary Machines Using Machine Learning
Authors: Brandao Iago M. , Costa Cesar da
Published: September 2022

Classification of faults in rotary machines using machine learning is gaining attention in the field of science and engineering. In rotating machinery, misalignment is a common fault. This type of fault has been extensively studied in the literature using the vibration signals produced by rotary machines. This study proposes an approach based on machine learning techniques to diagnose misalignments in rotary machines under various conditions. A personalized diagnostic fault approach is proposed to detect misalignment faults. The approach includes three steps. First, the data acquisition model is developed to obtain signals (fault samples). The rotor vibration signals in stationary rotation conditions were obtained by two inductive proximity sensors with analog output, and the data were collected by a data acquisition device. Then, to generate the faulty training samples, each data acquisition signal is transformed to the frequency domain using Fast Fourier Transform (FFT). Finally, using the samples obtained through the feature selection techniques, machine learning algorithms Random Forest, Naïve Bayes and SVM were evaluated, resulting in classifications with different efficiencies. The results show that the SVM algorithm outperforms the Naïve Bayes and Random Forest algorithms when the same number of features is used. The proposed personalized diagnostic approach was applied to detect faults of rotating electrical machines misalignment with success.

Noises in marine seismic data are one of the biggest obstacles in seismic imaging. The most significant step in seismic data processing is the removal of seismic noise, which can be classified as instrument and background noise. Noise attenuation usually results in improved seismic interpretation by increasing the signal-to-noise ratio. In this study, we will focus on attenuating these seismic noises with several data processing techniques. A number of denoising examples describing swell, strumming/tugging, cavitation, which are background type noises, and streamer-mounted device noise (Nautilus), which is an instrument type noise, were illustrated by analysing a marine 3D seismic dataset which recorded by Oruc Reis Research Vessel in Black Sea project of MTA (Mineral Research and Exploration). This study was achieved by implementing f-x prediction filter (SPARC, DENOISE3D) and f-k filter (DWATT) in t-x domain, radon filter (RADATT) in Tau-P domain by the use of Geovation 2.0 software.
Classification of Publications by Document Types in Web of Science and Scopus: Similarities, Differences and their Value in the Analysis of Publication Activity
Authors: Mokhnacheva Yuliya
Published: September 2022

The article presents comparative data concerning the types of the same publications in two of the world’s leading scientific information systems – Web of Science and Scopus – and publishers. The paper shows significant differences in the typification of documents in a sample of 4338 most actively cited works with Russian authorship of various types for the period 2010-2020. The article shows that the type of publication is not an obvious criterion: the same work can be assigned a different type depending on the source of information. The revealed discrepancies of information from various sources give grounds for a certain skepticism in the correctness of the formulation of tasks in the analysis of publication activity concerningthe accounting of publications of only certain types. The results of the study suggest that if it is necessary to take into account only certain types of publications, information about the types of documents should be verified with the original information from publishers.

Introducción: El estudio o trabajo independiente es una estrategia que desarrolla el estudiante para alcanzar los objetivos formativos propuestos. Diversos países consideran al estudio independiente dentro de los créditos del programa formativo. Objetivo: Evaluar el estudio independiente en los estudiantes del cuarto año del programa de Estomatología de la Universidad Peruana Cayetano Heredia. Material y Métodos: El estudio fue transversal, observacional y descriptivo. La población estuvo conformado por 49 estudiantes del cuarto año matriculados en el Programa de Pregrado de Estomatología de la Universidad Peruana Cayetano Heredia, en el año 2021. El cuestionario en Google forms estuvo constituido por cuatro dimensiones y once preguntas, fue enviado por correo electrónico institucional. La encuesta fue validada (Alfa de Cronbach=0,96). Resultados: El 81,6% fueron mujeres. El promedio de horas que dedicaron al estudio independiente entre lunes y viernes fue de 3 horas (DS=1,4; Mín=1; Máx=6) y en días sábado y domingo fue de 3,4 horas (DS=1,4; Mín=0; Máx=7). El 38,8% consideraron que no fue suficiente el tiempo que dedicaron al estudio independiente. Como actividad regular, emplearon 4,2 horas para un método de caso y para realizar actividades de laboratorio de ortodoncia, y como actividad ocasional, 8,4 horas para el portafolio. En la dimensión personal el 71,4% tenían responsabilidades en sus hogares, dimensión emocional65,3% presentaron tensión o estrés, y en la dimensión física, 14,3% presentaron problemas de salud. El 57,1% consideraron que fue adecuado el ambiente de estudio y el 81,6% que fue importante el estudio independiente. Conclusiones: El estudio independiente sumado a las actividades lectivas, implica diez horas de dedicación del estudiante del cuarto año, entre los días lunes y viernes, lo cual puede representar una sobrecarga de horas que límite sus actividades personales y responsabilidades.

Mucocele is an inflammatory lesion of the common salivary gland in the oral cavity, generated by the accumulation of saliva, from the rupture of the minor salivary gland duct. The objective of this report was to describe a case of extravasation phenomena treated with high-power diode laser in association with photobiomodulation. The patient presented a nodular, exophytic lesion on the lower lip, similar in color to the mucosa, measuring 2 cm in diameter. Excisional biopsy was performed with high-power diode laser. Immediately after surgery and weekly thereafter, photobiomulation was performed with lower-power diode. After one-month, total repair of the surgical wound was observed, with minimal scarring, without lesion recurrence during 14 months of follow-up. Therefore, the treatment protocol used proved to be an effective, safe and fast alternative, bringing greater comfort to both professional and patient during the trans and postoperative periods.

Compartmental models that dynamically divide the host population in categories such as susceptible, infected and immune constitute the mainstream of epidemiological modelling. Effectively such models treat infection and immunity as binary variables. We constructed an individual based stochastic model that considers immunity as a continuous variable and incorporates factors that bring about small changes in immunity. The small immunity effects (SIE) comprise cross immunity by other infections, small increments in immunity by sub clinical exposures and slow decay in the absence of repeated exposure. The model makes qualitatively different epidemiological predictions including repeated waves without the need for new variants, dwarf peaks (peak and decline of a wave much before reaching herd immunity threshold), symmetry in the upward and downward slopes of a wave, endemic state, new surges after variable and unpredictable gaps, new surge after vaccinating majority of population. In effect the SIE model raises alternative possible causes of the universally observed dwarf and symmetric peaks and repeated surges, observed particularly well during the Covid-19 pandemic. We also suggest testable predictions to differentiate between the alternative causes for repeated waves. The model further shows complex interactions of different interventions that can be synergistic as well as antagonistic. The model suggests that interventions that are beneficial in the short run can also be hazardous in the long run.

Controlled deposition of CoCrFeNiMo0.2 high entropy alloy (HEA) micro-particles was achieved using laser induced forward transfer (LIFT). Ultra-short laser pulses, 230 fs of 515 nm wavelength, were tightly focused into ∼ 2.4 μm focal spots on the ∼50 nm thick plasma-sputtered films of CoCrFeNiMo0.2. The HTA films were transferred onto glass substrates by magnetron sputtering in vacuum (10−8 atm) from the thermal spray coated substrates. The absorption coefficient of CoCrFeNiMo0.2 α ≈ 6 × 105 cm−1 was determined at 600 nm wavelength. The real and imaginary parts of refractive index (n + iκ) of HEA were determined from reflectance and transmittance using nano-films.

Published: September 2022

In this article we have estimated the value of “Opportunity Driven Entrepreneurship” in Europe. We use data from European Innovation Scoreboard-EIS of the European Commission for 36 countries in the period 2010-2019. We use Panel Data with Fixed Effects, Panel Data with Random Effects, WLS, Pooled OLS, and Dynamic Panel. Our results show that “Opportunity Driven Entrepreneurship” is positively associated, among others, to “Innovation Friendly Environment” and “Turnover Share Large Enterprises”, while it is negatively associated, among others, to “Sales Impacts” and “R&D Expenditure Business Sectors”.

Published: September 2022

Although impending urbanization is a well-acknowledged problem, there is a rising concern about how the urban forms will change and what can be the impacts on the global energy demand. As hubs of economic, social and cultural activities, cities are major energy consumers and GHG emissions. Energy consumption is a technical or a spatial problem? From Newman and Kenworthy to today, several studies have tried to shed light on this nexus. In this work, the controversial paradigm of urban density is discussed as a key component of the fight against climate change impacts. Concerning energy consumption, an in-depth bibliometric analysis is developed to identify the interdependencies of the terms. As a key ‘promise’ of an efficient urban configuration, density has been the core of diverse studies but with still under exploration arguments. This work provides a way forward for planners seeking to design strategies related to dense urban tissues exploring controversial paradigms as a key solution for energy-efficient problems.

After surgery, oral cavity healing occurs in a hostile environment and requires proper oral care and hygiene to accelerate recovery. The aim of the current study is to investigate and compare the bioreactivity characteristics of chlorhexidine based (CHX) mouth rinse and a novel bone bioactive liquid (BBL) mouth rinse on oral healing within seven days application post-surgery. A randomized, double blind clinical trial conducted in 81 patients. The mouth rinses were applied twice a day for a period of 7 days. The visual analog scale (VAS) protocol was applied to measure pain index. Early wound healing score (EHI) was determined in evaluate the oral cavity healing progress. No adverse effects were observed using the mouth washes, but CHX resulted in teeth staining. CHX and BBL were sufficient to reduce pain over a period of 7 days. However, the BBL group demonstrated a statistically significant reduction in VAS stating day 4. Relative to CHX group, the EHI scores were significantly higher in the BBL group, independent from the tooth location. No gender differences were observed in both VAS and EHI scores. Relative to the commercially available CHX, BBL mouth rinse reduced pain and accelerated oral cavity healing. Suggesting an improvements of oral cavity microenvironment at the wound site that mediates soft tissue regeneration.
