Published: June 2020

Enriched coal as an energy source has a number of undeniable environmental and economic advantages, and has a higher calorific value. Important characteristics that affect the technological process of coal flotation are the particle size distribution, the shape of the coal particles and their surface texture. Screen analysis is the most common method for determining the granulometric composition of granular media. However, it is not sensitive to the shape of the particles and the nature of their surface. With the sieve method of analysis, there is no direct measurement of any axes of the particle, except the case when the particle is ball-shaped. In this case, its size coincides with the edge length of the square mesh of the sieve. Thus, two particles of completely different shapes can pass through the same sieve opening. Our task was to develop a simple technique that allows identifying the shape and texture parameters of particles of the bulk material. To solve the problem in question, the algorithm implemented in MATLAB (Image Processing Toolbox) and the concept of fractals are used. A method for estimating the shape and texture of bulk material particles based on digital image processing has been proposed. The particle size distribution curves are constructed, obtained by sieving method and image processing method. It was found that these curves are in good agreement with each other. Digital image processing is an alternative to identifying the important quality characteristics of bulk materials.
Does Scientific Uncertainty in News Articles Affect Readers’ Trust and Decision-Making?
Authors: Hendriks Friederike , Jucks Regina
Published: June 2020

Even though a main goal of science is to reduce the uncertainty in scientific results by applying ever-improving research methods, epistemic uncertainty is an integral part of science. As such, while uncertainty might be communicated in news articles about climate science, climate skeptics have also exploited this uncertainty to cast doubt on science itself. We performed two studies to assess whether scientific uncertainty affects laypeople’s assessments of issue uncertainty, the credibility of the information, their trust in scientists and climate science, and impacts their decision-making. In addition, we addressed how these effects are influenced by further information on relevant scientific processes, because knowing that uncertainty goes along with scientific research could ease laypeople’s interpretations of uncertainty around evidence and may even protect against negative impacts of such uncertainty on trust. Unexpectedly, in study 1, after participants read both a text about research methods and a news article that included scientific uncertainty, they had lower trust in the scientists’ assertions than when they read the uncertain news article alone (but this did not impact trust in climate science or decision-making). In study 2, we tested whether these results occurred due to participants overestimating the scientific uncertainty at hand. Hence, we varied the framing of uncertainty in the text on scientific processes. We found that exaggerating the scientific uncertainty produced by scientific processes (vs. framing the uncertainty as something to be expected) did not negatively affect participants’ trust ratings. However, the degree to which participants preferred effortful reasoning on problems (intellective epistemic style) correlated with ratings of trust in scientists and climate science and with their decision-making. In sum, there was only little evidence that the introduction of uncertainty in news articles would affect participants’ ratings of trust and their decision-making, but their preferred style of reasoning did.
Third-Person Perceptions and Calls for Censorship of Flat Earth Videos on YouTube
Authors: Landrum Asheley R. , Olshansky Alex
Published: June 2020

Calls for censorship have been made in response to the proliferation of flat Earth videos on YouTube, but these videos are likely convincing to very few. Instead, people may worry these videos are brainwashing others. That individuals believe other people will be more influenced by media messages than themselves is called third-person perception (TPP), and the consequences from those perceptions, such as calls for censorship, are called third-person effects (TPE). Here, we conduct three studies that examine the flat Earth phenomenon using TPP and TPE as a theoretical framework. We first measured participants’ own perceptions of the convincingness of flat Earth arguments presented in YouTube videos and compared these to participants’ perceptions of how convincing others might find the arguments. Instead of merely looking at ratings of one’s self vs. a general ‘other,’ however, we asked people to consider a variety of identity groups who differ based on political party, religiosity, educational attainment, and area of residence (e.g., rural, urban). We found that participants’ religiosity and political party were the strongest predictors of TPP across the different identity groups. In our second and third pre-registered studies, we found support for our first study’s conclusions, and we found mixed evidence for whether TPP predict support for censoring YouTube among the public.
Pro-Science, Anti-Science and Neutral Science in Online Videos on Climate Change, Vaccines and Nanotechnology
Authors: Erviti M. Carmen , Codina Mónica , León Bienvenido
Published: June 2020

Online video has become a relevant tool to disseminate scientific information to the public. However, in this arena, science coexists with non-scientific or pseudoscientific beliefs that can influence people’s knowledge, attitudes, and behavior. Our research sets out to find empirical evidence of the representation of pro-science, anti-science and neutral stances in online videos. From a search on Google videos, we conducted content analysis of a sample of videos about climate change, vaccines and nanotechnology (n = 826). Results indicate that a search through Google videos provides a relatively small representation of videos with an anti-science stance, which can be regarded as positive, given the high potential influence of this search engine in spreading scientific information among the public. Our research also provides empirical evidence of the fact that an anti-science stance is more frequent in user-generated content than in videos disseminated by other types of producers.
Spreading (Dis)Trust: Covid-19 Misinformation and Government Intervention in Italy
Authors: Lovari Alessandro
Published: June 2020

The commentary focuses on the spread of Covid-19 misinformation in Italy, highlighting the dynamics that have impacted on its pandemic communication. Italy has recently been affected by a progressive erosion of trust in public institutions and a general state of information crisis regarding matters of health and science. In this context, the politicization of health issues and a growing use of social media to confront the Coronavirus “infodemic” have led the Italian Ministry of Health to play a strategic role in using its official Facebook page to mitigate the spread of misinformation and to offer updates to online publics. Despite this prompt intervention, which increased the visibility and reliability of public health communication, coordinated efforts involving different institutions, media and digital platform companies still seem necessary to reduce the impact of misinformation, as using a multichannel strategy helps avoid increasing social and technological disparities at a time of crisis.
Africa and the Covid-19 Information Framing Crisis
Authors: Ogola George
Published: June 2020

Africa faces a double Covid-19 crisis. At once it is a crisis of the pandemic, at another an information framing crisis. This article argues that public health messaging about the pandemic is complicated by a competing mix of framings by a number of actors including the state, the Church, civil society and the public, all fighting for legitimacy. The article explores some of these divergences in the interpretation of the disease and how they have given rise to multiple narratives about the pandemic, particularly online. It concludes that while different perspectives and or interpretations of a crisis is not necessarily wrong, where these detract from the crisis itself and become a contestation of individual and or sector interests, they birth a new crisis. This is the new crisis facing the continent in relation to the pandemic.
German Media and Coronavirus: Exceptional Communication—Or Just a Catalyst for Existing Tendencies?
Authors: Wormer Holger
Published: June 2020

The Covid-19 pandemic has immediate effects on science journalism and science communication in general, which in a few cases are atypical and likely to disappear again after the crisis. However, from a German perspective, there is some evidence that the crisis—and its accompanying ‘infodemic’—has, above all, accelerated and made more visible existing developments and deficits as well as an increased need for funding of science journalism.

Abstract In recent years, there has been a steady increase in the incidence of bladder cancer (RMP) in our country. So, over the past ten years there has been an increase in the number of cases of primary diagnosis of RMP by more than 1.5 times, which corresponds to 77.1 cases per 100,000 population. At the same time, mortality in the first year for the same time period decreased from 22.4% in 2008 to 14.4% in 2019. In 75% of patients, this disease is diagnosed at an early stage (the tumor spreads to the muscle layer — non-muscle-invasive forms of RMP), which allows organ-preserving treatment. One of the factors influencing these indicators is the introduction of new diagnostic search methods into the routine of doctors. Such methods include: photodynamic and narrow-spectrum diagnostics when performing cystoscopy, as well as other methods of increasing the visualization of hidden tumors.

Published: June 2020

At the present time primary-multiple malignancies are of interest in connection with the frequency of prevalence, which remains at the rather high level and continues to grow up, therefore increasing the relevance of this pathology in clinical oncology and everyday practice. With the exception of the treatment of primary multiple malignancies requiring a multimodal approach, as well as in the case of the use of complex treatment in conjunction with chemotherapists and radiotherapy specialists. In the past three decades, the development of screening tests that prevent and detect some cancers at an early, more treatable stage, and treatment advances have increased the 5‑year relative survival rate for all cancers to 66%. In addition to concerns about cancer recurrence, survivors also worry about their risk of developing a new cancer. Prostate cancer is a leader in terms of morbidity and mortality in the world, just as often are found in combination with other malignant tumors. However, given the high detectability of prostate cancer, primary patients are currently receiving radical treatment, and if metastatic prostate cancer is detected, they are receiving drug treatment, which improves the survival and quality of life of patients. Soft tissue sarcomas are rare malignant tumors that develop in the connective tissues and remain poorly understood due to the fact that they make up less than 1% of all malignant diseases. One of the main methods for treating soft tissue sarcomas is the surgical method. Soft tissue sarcomas are difficult to treat and therefore it is imperative that surgeons and other specialists have experience in treating this disease. Studies show that patients with this pathology show better results if they receive treatment in specialized cancer centers that have experience in treating soft tissue sarcoma. This article demonstrates the clinical case of surgical treatment of a patient with primary multiple retroperitoneal tumors and metastatic prostate cancer.

Published: June 2020

Purpose of the study. Improving the work of the admission department of a large multidisciplinary hospital with the help of new organizational technologies.

Materials and methods. The basis of the study is N.I. Pirogov Samara State Clinical Hospital No. 1. The paper used methods of organizational modeling and statistical analysis.

Results. Prior to the introduction of new organizational patient-oriented technologies, the following problems were identified in the hospital admission department: mixing flows of planned and emergency patients, patients with a neurological and cardiology profile, patients receiving paid services; the inability to provide resuscitation in the ward; ineffective routing and coordination of patients; the start time for medical care ranged from 30 minutes to 3 hours. After improving the organization of medical care in the admission department, the infrastructure, the order of the department, the staffing of the department and the logistics of patients changed. The flows of patients were divided, zones for emergency patients were allocated: the “red zone” is intended for patients in an extremely serious condition with impaired vital functions; The "yellow zone" is intended for patients who are in a serious condition or in a state of moderate severity, with impaired self-movement, the "green zone" is intended for patients whose health condition does not threaten life. As a result of the introduced changes, the time to begin providing medical care to patients in serious condition was reduced to 1–2 minutes, the time spent by patients in the admission department was reduced to an average of 40 minutes, the number of outpatients received over the past three years increased by 37.7% (from 15528 to 21387).

Conclusion. As a result of improving the work of the admission department, the time spent by patients in the admission department was reduced; increased throughput of the department; qualitative and quantitative indicators of work have changed.

Purpose of the study. A comparative analysis of the intensity of lipid peroxidation and the functioning of various units of the antioxidant system in the blood of patients with malignant pancreatic lesions and with chronic pancreatitis.

Patients and Methods. The content of malondialdehyde (MDA) and diene conjugates, the activity and content of antioxidant enzymes (superoxide dismutase, catalase, glutathione reductase, glutathione peroxidase), the content of reduced glutathione and blood thiol status, as well as the content of vitamins E and A (as indicators of the non-enzymatic link of the antioxidant system), were studied in the blood of 51 patients before treatment and 22 donors. Based on a histological study of tumors, patients were divided into groups: neuroendocrine pancreatic cancer, pancreatic adenocarcinoma, pancreatic adenocarcinoma with a neuroendocrine component; a group of patients with chronic pancreatitis was also identified.

Results. According to most of the studied parameters, neuroendocrine cancer differs from pancreatic adenocarcinoma in a more pronounced imbalance in the functioning of all units of the antioxidant system, which contributes to a greater intensification of free radical processes. Chronic pancreatitis was characterized by a lower content of all the studied antioxidant enzymes, as well as a decrease in the thiol status of the blood as compared with a malignant pancreatic lesion, which was possibly associated with the highest MDA level in the plasma of patients with chronic pancreatitis. At the same time, the content of vitamin E in chronic pancreatitis was significantly higher than for adenocarcinoma and adenocarcinoma with a neuroendocrine component.

Conclusions. The most pronounced violation of oxidative status is one of the metabolic features of neuroendocrine cancer. Differences revealed in patients with neuroendocrine cancer, adenocarcinoma and pancreatitis can be useful both in the diagnosis of different types of pancreatic lesions and for assessing the state of patients during treatment.
Synergistic ideas in oncology: prospects for practical implementation
Authors: Evstratova E. S. , Petin V. G.
Published: June 2020

The review is devoted to the analysis of the problem of synergistic ideas application in oncology after simultaneous combined application of agents. An example of the determination and quantification of the synergistic enhancement ratio is presented. It is emphasized that independent addition is determined by product of probabilities of the effects induced by each agent applied separately. Elevated temperatures synergistically enhance the lethal effect of ionizing radiation and chemical compounds used in the treatment of cancer. Analyzing the dependence of the synergistic effect on the acting temperature after its simultaneous application with ionizing radiation or cisplatin, the existence of an optimal temperature ensuring the greatest synergistic interaction was shown for cultured mammalian and yeast cells. The universal regularities of the manifestation of synergism, independent on the agents, biological objects and tests used, are noted. The greatest synergy is observed with the simultaneous application of agents. The synergism recorded as a result of the combined effects of two factors is observed only with a certain ratio of the effects induced by each agent. Synergism depends on the intensity of the factors used — the current temperature, the dose rate of ionizing radiation or the concentration of chemical agents. These universal patterns have been demonstrated for proand eukaryotic cells, including oncological origin. The existence of universal patterns of synergism indicates the need to develop a new paradigm and theoretical model of synergism, which should take into account the identified patterns. An original biophysical concept of synergistic interaction is proposed. Concrete results are presented that demonstrate the possible ways of using the ideas of synergism in oncology by achieving the greatest synergistic enhancement ratio for the combined effects of various physical and chemical agents. It is concluded that the knowledge and the application of the ideas and general patterns of synergy described in this paper can be useful for specialists using the simultaneous action of various agents to optimize combined treatment methods in modern oncology.
Mitochondria of transformed cell as a target of antitumor influence
Authors: Frantsiyants E. M. , Neskubina I. V. , Sheiko E. A.
Published: June 2020

Mitochondria are intracellular organelles in eukaryotic cells that participate in bioenergy metabolism and cell homeostasis, including ATP generation through electron transport and oxidative phosphorylation in combination with oxidation of metabolites by the tricarboxylic acid cycle and fatty acid catabolism via β-oxidation. the production of reactive oxygen species, as well as the initiation and implementation of apoptosis. Mitochondria play a crucial role in cellular energy metabolism and the regulation of programmed cell death. mitochondria activate numerous signaling pathways associated with cell death. Mitochondria have the ability to control the activation of programmed cell death by regulating the translocation of proapoptotic proteins from the intermediate space of mitochondria to the cytosol. This is the reason for the emergence of a new discipline — mitochondrial medicine. The review examined and analyzed scientific publications on the role of mitochondria in the life support of transformed cells, the study of their functioning and structurally functional dysfunctions, as part of mitochondrial medicine. Mitochondrial medicine is a developing discipline whose significance stems from the central function of mitochondria in the production of adenosine triphosphate, the generation of reactive oxygen species, and cell death due to necrosis or apoptosis. Consequently, mitochondrial dysfunction plays an important role in the pathophysiology of cancer, many other common diseases and side effects of drugs. Perhaps the combined use of modulators of mitochondrial metabolism and antitumor therapy will contribute to the emergence of a new direction in antitumor treatment, which will significantly increase the effectiveness of cancer treatment.

Intergroup Perception of Men and Women with Different Levels of Negative Traits
Authors: Baleva M.V.
Published: June 2020

Objectives. The study of male and female intergroup perception in terms of categorization by personal similarity and attractive / repulsive personal traits.
Background. Today, the question of the basic factor in the attitudes formation remains highly relevant. Two of the strongest “competitors” claim to this role — homophilia and prosocial traits. Knowing the specific gravity of factors forming the relationship to the Other can help in the developing of effective forecasts for psychological compatibility and impression effects.
Study design. A quasi-experimental design was used. Indicators of objective and subjective personal similarity of respondents with the object of perception (in consideration of gender) were regarded as independent variables. The relation to the object (including cognitive, emotional, and behavioral components) was measured as a dependent variable.
Participants. 414 students 18—24 years old, 86 male and 328 female.
Measurements. Short Dark Triad; Attitude Scale. Stimulus material — video interview with a young man or young woman.
Results. The effect of depolarization of the “good” and “bad” objects of the opposite sex was revealed for respondents with a high level of Dark Triad. This regularity is determined by gender specificity, and also “works” differently in the case of different Dark Triad traits and attitude components. Subjective awareness of similarities with the “bad” object leads to the most radical revision of his personal valence.
Conclusions. Personal valence of the perceived object plays the key role in attitudes towards the Other. The factor of homophilia plays the secondary role, but in the case of inter-sexual perception it can lead to leveling and even inversion of the “good” and “bad” Other assessments.
Spectroscopy of a chemically peculair delta scuti-type star: 60 tau

In this study, a detailed spectroscopic analysis of 60 Tau is presented. 60 Tau is a Delta Scuti-type pulsating variable and it is also a metallic-lined (Am) star. The pulsation mechanism of Delta Scuti stars have been thought to be well understood and it was also suggested that metallic-lined stars did not exhibit pulsations. However, in recent studies, particularly with Kepler and TESS observations, many metallic-lined Delta Scuti stars have been found. Additionally, it turned out that the current pulsation mechanism of Delta Scuti stars including metallic-lined ones has not fully understood. Therefore, to make a reliable investigation for the driving mechanism of Delta Scuti variables, we need to know precise fundamental stellar (mass, radius) and atmospheric (Teff, log g, microturbulence) parameters of these variables. Hence in this study, the atmospheric parameters, projected rotational velocity and the chemical abundances of 60 Tau were obtained by using the high-resolution and high signal-to-noise spectra. The position of the star is found in the H-R diagram and the Delta Scuti instability strip using Gaia luminosity.
Comparison of greedy matching methods on cigarette usage of individuals in Turkey
Authors: NAZMAN Ezgi , OLMUŞ Hülya
Published: June 2020

There has been a growing interest in using observational studies to estimate treatment effects on outcomes where treatment selection is often influenced by covariates. Recently, propensity score matching (PSM) method has increasingly being used to reduce bias in estimated treatment effect for observational studies. Greedy Matching (GM), one of the PSM methods, is widely preferred in many studies because of the calculation simplicity of the method. However, GM is still open to be evaluated in terms of bias reduction and classification performances. For this purpose, data including cigarette usage of 17242 individuals in Turkey were used for the comparison of nearest neighbor, caliper, stratification, Mahalanobis metric, and combined propensity score and Mahalanobis metric matching methods in terms of average standardized bias, bias reduction, and accuracy rate. The stratification-matching method should be preferred for not only low standardized bias and high bias reduction, but also high accuracy rate.

Published: June 2020

A stationary field experiment of a reduced soil tillage was implemented at a Hypogley (Hypogleyic soils A–Gso–Gr soil horizon sequence) soil type of Eastern Croatia during three seasons and set up as a split-plot randomized block design in four repetitions. The tillage systems (TS) were as follows: 1) conventional tillage, i.e., plowing at 30 cm (CT), 2) disking up 10-12 cm (DT), 3) soil loosening up to 35 cm (LT), 4) no-tillage (NT). The experiment was designed to compare the penetration resistance (PR), soil moisture (SM), and bulk density (BD) at different TSs and soil depths. A cone penetrometer was used to measure the PR with 10 prods per TS, accompanied with a measurement of SM with a soil auger on every 10 cm, with four samples up to a 40-cm depth. The BD was determined by metal cylinders on every 10 cm up to a 30-cm depth, being weighed and dried thereafter to obtain an absolutely dry sample, and then calculated using absolutely a dry soil sample mass (m_s) and the soil volume (V). The PR and SM were significantly influenced by the TS and soil depth. The CT had the significantly lowest PR at all depths, while the DT has manifested a significantly higher PR at a soil depth amounting to 10 to 20 cm. The PR on NT were significantly diverse from the CT at all soil depths. The BD varied significantly concerning the TS and the soil depth. Subsequent to the three years, the CT had a significantly smaller BD at a depth amounting from 0 to 10 cm, and a significantly higher BD at 20- to 30-cm depth, compared to reduce the TS.

Background: Hypotrophy is a major contributor to neonatal mortality and morbidity in underdeveloped countries. In Madagascar, efforts have been made to improve this situation, particularly with regard to prevention and early treatment. This prevention is mainly focused on the search for determining factors. Fetal Alcohol Syndrome (FAS) is not yet mentioned in Madagascar although more than 9% of Tananarivian women drink alcohol. A study was conducted in our department to determine the relationship between maternal alcohol intake and hypotrophy.Methods: The prospective study was carried out in the pediatrics department of the Joseph Raseta Befelatanana University Hospital Centre, on hospitalized hypotrophic newborns (below the 10th percentile) over a period of 3 months from December 1, 2018 to February 31, 2019. In the newborn, authors studied facial features, neurological abnormalities and associated malformations. For the mother, alcohol consumption, pregnancy information was analyzed. The character of FAS could thus be classified.Results: Author counted 21 hypotrophs among the 128 newborns hospitalized during this period. The facial abnormalities observed were: upper lip thickness abnormality (9.5%) and retrognathism (4.7%). Neurological signs described were: difficulty sucking (76.1%), hypotonia (66.6%), restlessness (9.5%), hyper-responsiveness (9.5%), hypertonia (9.5%) and tremor (4.7%). Two organ malformations (9.5%) were seen: cardiac and biliary tract malformations. Only one mother (4.7%) admitted having taken alcohol during pregnancy. Seven cases of familial alcoholism were reported. At the end of this study, we were able to identify only one case of doubtful FAS (4.7%), 2 cases of suspected FAS (9.5%) and 1 case of confirmed FAS (4.7%).Conclusions: This syndrome remains under-diagnosed in Madagascar due to the lack of staff training on FAS and the non-systematization of the search for its signs during systematic visits.

Published: June 2020

Background: Neonatal death is one of the major contributors (50%) of Under-five child mortality and 70% of the infant mortality. The main causes of neonatal deaths are prematurity and low birth weight (LBW). This study was undertaken to assess newborn foot length and determine its usefulness in identifying LBW/Preterm Babies.Methods: This is a cross sectional hospital based study of 173 newborn babies, done in KIMS Hospital, Bengaluru. All live newborn infants were included in the study. Newborn babies with lower limb congenital anomalies were excluded from the study.Results: Out of 173 newborn, 99 babies were male (57%) and 74 were female (43%). 122 (70.5%) were term and 51(29.5%) were preterm. 48 (38%) were SGA, 120 (69%) were AGA and 5 (3%) were LGA. Their gestational age ranged from 28 to 40 weeks. In this study positive Correlation between foot length and gestational age was found with the “r” value of 0.823. The study also showed a positive correlation between foot length and weight with the “r” value of 0.831.Conclusions: This study has a good correlation of Foot length with gestational maturity and birth weight. Foot length of 7.45cm can be used as a cut- off point for differentiating between term and preterm babies. Derived equation from this study can be used by ASHAs and Anganwadi workers for the estimation of gestational age in resource poor situations and refer the preterm newborns to higher centres for further management as early as possible to prevent long and short term complications of prematurity.
