Published: August 2020

BACKGROUND. Congenital abnormalities of the kidneys and urinary tract in children are included in the concept of CAKUT (con­genital anomalies of the kidney and urinal tract) - a syndrome and are often accompanied by changes in the cardiovascular system, which requires an interdisciplinary approach when observing them. THE AIM: to evaluate the nature and frequency of morphofunctional disorders ofthe cardiovascular system in children with CAKUT syndrome and optimize their medical follow-up. PATIENTS AND METHODS. 120 children were examined-90 with CAKUT syndrome (group 1) (24 - the doubling of the urinary tract, 36 - with congenital hydronephrosis, 30 - with polycystic kidney disease), and 30 practically healthy children (group 2). In group 1, there were 38 (42.2%) boys and 52 (57.8%) girls aged 4 to 16 years (average age 8±5.82 years), in group 2-13 (43.3%) boys and 17 (56.7%) girls aged 4 to 15 years (average age 6±6.73 years). A comprehensive examination of the urinary and cardiovascular systems was performed using ultrasound diagnostics and Holter monitoring of ECG and blood pressure. Statisti­cal processing was performed using the program "Statistica 8.0"("Stat Soft Inc., USA"). RESULTS. In CAKUT syndrome, often chronic infection was registered in children with a doubling of MVP (91.7%), hydronephrosis (88.9%). Persistent and increased crystalluria was observed in every third patient (33.3%) with a doubling of MVP, in 47.2% of children with hydronephrosis, and in almost 2/3 of patients (73.3%) with the polycystic disease. In children with CAKUT syndrome, congenital heart disease was de­tected in 15.0% of cases, with a high frequency of small heart abnormalities with a predominance ofthe left ventricular false chord (38.9%) and mitral valve prolapse (33.6%). CONCLUSION. The data obtained by us justify the need to include in the standard of dispensary observation of children with urinary tract congenital malformation examination by a pediatric cardiologist 1 -2 times a year with additional examination ofthe cardiovascular system (ECG, heart ultrasound, and daily blood pressure monitoring).

Published: August 2020

BACKGROUND. The study of the prognostic significance of markers of tubular dysfunction in patients with the acute coronary syndrome (ACS) and arterial hypertension (AH) is highly relevant, due to the unity of pathogenetic mechanisms and their consequences that develop during an acute coronary event. PURPOSE. Analysis of the influence of tubular dysfunction indi­cators on the risk of cardiovascular complications in patients with hypertension in the late period after ACS. PATIENTS ANDMETHODS. The study included 103 patients with hypertension and ACS. All patients included in the study underwent coronary angiography (CAG) with stenting of the coronary arteries. Before CAG, clinical and anamnestic data were collected, labora­tory (including creatinine and urea, potassium and sodium, plasma osmolarity), and instrumental diagnostic methods were used. The concentration of potassium and sodium in the daily urine, potassium and natriuresis, osmolarity of urine, and the calculated osmolar clearance index (ОС) were determined. Impedance spectrometry was performed to determine the water balance of the body's liquid media. After 17.0±0.51 months, the endpoints of the study were registered: AMI, NS, stable stress angina, repeated myocardial revascularization (RM), and death. RESULTS. It was found that an increase in ОС is associated with the risk of developing repeated RM in the late period after ACS (x2-criterion = 3.89, p = 0.04). Among the indicators of the electrolyte balance of urine, a statistically significant effect on the risk of repeated RM was found with an increase in the con­centration of potassium in the urine (x2-criterion = 4.63, p = 0.03) and daily potassium urea (x2-criterion = 4.85, p = 0.03). The ОС index and an increase in the electrolyte balance of urine were considered and justified as markers of tubular dysfunction. The complex effect of increasing the ОС and reducing the volume of intracellular fluid from the proper values (x2-criterion = 6.16, p = 0.4) on the risk of repeated RM was established. It was found that when the balance of the volume of total fluid and CA is changed, the risk of developing repeated RM is potentiated. It is shown that with the excessive introduction of fluid volume into the body, mainly intravenously and an increase in ОС, the risk of developing repeated RM increases significantly. CONCLU­SION. The study revealed that the presence of tubular dysfunction can be considered as a predictor of adverse cardiovascular prognosis in patients with ACS and hypertension. For a comprehensive analysis of the risk value, it is necessary to control homeostasis and individual selection of the volume of intravenous infusions.

Published: August 2020

BACKGROUND. The increasing prevalence of chronic kidney disease is a global trend as well in general as in terminal kidney failure in particular. Of great interest is the analysis of the impact of mineral and bone disorders on the risk of cardiovascular complications and, first of all, acute myocardial infarction (AMI ). THE AIM: to assess the impact of bone mineral disorders on the risk of AMI in patients with stage 5D chronic kidney disease. PATIENTS AND METHODS. It was conducted a prospective (three-year) cohort study of 85 patients with CKD S5D treated with programmed hemodialysis. At the first stage, it were reg­istered the risk factors and clinical manifestations of CKD 5 St, as well as indicators that characterized bone mineral disorders (levels of blood inorganic phosphate, calcium, parathyroid hormone, 1,25(OH)D, fibroblast growth factor (FGF-23), a-Klotho). Signs of calcification of the heart valves and aortic wall were also determined. The second stage involved a re-examination of patients after 3.1±0.1 years, as well as registration of endpoints, which were identified as cases of fatal and non-fatal AMI. RESULTS. After 3 years of follow-up, the following endpoints were registered: nonfatal AMI - 6 cases, fatal AMI-4 cases. The risk of AMI increased in the presence of initial persistent hyperphosphatemia and 1,25(OH)D3 deficiency, as well as calcifica­tion of heart valves and high FGF-23 values, but only in combination with hyperphosphatemia and 1,25(OH)D3 deficiency. Hyperparathyroidism also increased the risk of AMI in conditions of a deficit of 1,25(OH)D3. The risk of nonfatal AMI cases was also increased by the presence of aortic calcification and its severity. The risk of AMI increases in the presence of initial persistent hyperphosphatemia and a deficit of 1.25 (OH)D3, as well as CCS, high FGF-23 values, but only in combination with hyperphosphatemia and a deficit of 1.25(OH)D3. Hyperparathyroidism also increases the risk of AMI in conditions of a deficit of 1.25(OH)D3. The risk of nonfatal cases of AMI also increases the presence of aortic calcification and its severity. CONCLU­SION. The risk of AMI increases in the presence of initial persistent hyperphosphatemia and a deficit of 1,25(OH)D3, as well as calcification of the heart valves, high FGF-23 values, but only in combination with hyperphosphatemia and a deficit of 1,25(OH) D3. Hyperparathyroidism also increases the risk of AMI in conditions of a deficit of 1.25(OH)D3. The risk of nonfatal cases of AMI also increases the presence of aortic calcification.

BACKGROUND. Determining the pathogenetic mechanisms of small-caliber renal artery remodeling in chronic glomerulone­phritis (GN) is an urgent task of nephrology, the implementation of which will allow establishing new diagnostic and therapeutic approaches to patients management. THE AIM: To evaluate the influence of hemodynamic, tubulointerstitial, and endothe- liotropic risk factors on the probability of remodeling of interlobular arteries in an experimental model of glomerulonephritis. MATERIALS AND METHODS. The experiment included 45 individuals of white mongrel rats, 3 of which were used to prepare an antigen suspension (AS), and 42 rats were divided into 4 groups: 9 individuals in the main groups (with the introduction of only AS, with the introduction of an incomplete Freund adjuvant, with AS and sodium chloride, with AS and perindopril) and 6 ratsin the control group. Glomerulonephritis was formed in the main groups of the experiment. Systolic blood pressure (SAD), the protein level in the urine, and the presence of edematous syndrome were monitored initially, on the 15th, 30th, and 60th day of the experiment. The size of the interlobular artery (MA) was determined by the morphological study, and the expression of VEGF and TGFp in the kidneys. RESULTS. Morphological signs of glomerulonephritis were obtained in all the main groups of the experiment as early as day 15. The greatest increase in SAD, protein in the urine, the presence of edematous syndrome in groups with the introduction of AS and AS with sodium chloride was found. The highest expression of VEGF and TGFp was found in these groups of rats. In the group with AS with perindopril, normotension was formed, the protein level was lower than in rats with AS with or without the use of sodium chloride, and there was no edematous syndrome. The expression of VEGF and TGFp was minimal. Interlobular artery remodeling in established groups of AS an AC with sodium chloride. In the remain­ing groups of rats, the size of the interlobular arteries was comparable to the control group. CONCLUSION. The leading role of systemic blood pressure in the remodeling of small-diameter kidney arteries in glomerulonephritis has been established. Despite the presence of active glomerulonephritis in rats, the structure of small arteries does not change during the formation of normotension.

Published: August 2020

BACKGROUND. The leading role in the development of vulvovaginitis in girls of pre-school age belongs to the extragenital diseases, including recurrent urinary tract infections. The study of medical and social factors that affect the development of reproductive health disorders is of urgent importance. THE AIM: to study the medical and social risk factors for recurrent vul­vovaginitis in preschool girls suffering from urinary tract infections. PATIENTS AND METHODS. A prospective controlled study was conducted in 107 girls aged 3-6 years, including group 1 (n=45) - patients with vulvovaginitis against the background of recurrent uncomplicated urinary tract infection; group 2 (n=32) - patientswith an isolated form of vulvovaginitis; group 3(n=30) - girls of health groups 1 and 2. The main parameters of social and biological anamnesis are analyzed. Statistical analysis was performed using the program "SPSS Statistics V. 17.0" ("SPSS Inc. IBM Company", USA). RESULTS. Patients with a combined form of vulvovaginitis, in comparison with patients with isolated vulvovaginitis, more often lived in rural areas, were from large families, belonged to the group of preschool children who do not attend preschool educational institutions, in their families, the monetary income was lower than the subsistence minimum (p<0.001). The lowest level of hygiene was observed in pa­tientswith isolated forms of vulvovaginitis. In patientswith combined forms of vulvovaginitis, in comparison with patientswith isolated vulvovaginitis, gestational complications were significantly higher: 22.2% had gestational pyelonephritis, 13.6% had a premature birth, and 22.2% had a cesarean section (p <0.05). CONCLUSION. Patients with vulvovaginitis and recurrent UTI have a burdened social and biological history. In dispensary management, an interdisciplinary approach is required, taking into account the identified medical and social risk factors.
Factors of immune protection in the pathogenesis of urinary infections (literature review)
Authors: Krutikov E. S. , Zhitova V. A.
Published: August 2020

In recent years, ideas about the pathogenesis of urinary tract infections have been changed significantly. Various pathogenetic factors of microorganisms and new defense mechanisms against them have been discovered. A significant part of pathogens is inactivated by the first line of defense - innate immunity which includes epithelial barriers (mucous membranes), cellular (phagocytes, dendritic cells, NK-cells) and humoral (chemokines, cytokines, complement) components, as well as antimi­crobial proteins). The second and more specific line of defense is the acquired (adaptive) immune system - humoral (B-cells, antibodies) immunity and cellular (T-cells) immunity. However, epithelial cells play an important role in the immune response. These cells interact with the components of both innate immunity and acquired one. Antimicrobial proteins are one of the most ancient and primitive components of the immune system and they are very widely spread in nature. More than 800 antimicro­bial proteins have been described and more than 100 of them have been found in the human body. The mechanism of these proteins is mainly connected with the violation of the bacterial membrane integrity. Nevertheless, some proteins can inhibit protein and/or DNA synthesis. The most common protein in the urine is uromodulin (Tamm-Horsfall protein), synthesized in the thick ascending section of the Henle loop. Uromodulin does not have direct antimicrobial activity, but it is involved in the pathogenesis of many inflammatory kidney diseases. In addition, uromodulin acting through the TLR4 signaling pathway pro­motes the maturation of dendritic cells, thereby further activating innate and acquired immunity. Currently, the role of antimi­crobial proteins and dendritic cells in the pathogenesis of the infectious process is being actively studied. It will probably have a significant practical value. Thus, the development of urinary tract infections is the process of competing for the interaction of the uropathogenic and the macroorganism. The treatment of these diseases (especially chronic) should not be limited to the use of antibacterial drugs. An important component of the pathogen eradication is to increase the activity of its own protective mechanisms.
Overcoming the unique history: heritage education as an instrument of cultural democratization in the Federal District
Authors: Pacheco Karolline
Published: August 2020

This article aims to reflect on the challenges and potential of heritage education in the context of the Federal District from a sociomuseological perspective. Considering that memory is the foundation for the construction of social identity and that this process is permanently redefined in the dialogical relationship with the other, heritage and museums are important instruments to reestablish these dialogues of diversity. In the face of museums and cultural spaces that reiterate the consecrated discourse about the construction of Brasilia, privileging specific names and facts, how to effectively enforce the relationship between heritage, identity and citizenship? I seek through experience as an educator in a cultural space to reflect on perceptions, potentialities and approaches that aim to overcome the unique history including other voices in this relationship in view of an education for autonomy and cultural democratization.

Memories of pain and construction of exhibitions: talking about femicide
Authors: Coronado Gabriela
Published: August 2020

Violent deaths of women for gender reasons, also known as femicides, continue to increase their numbers in Mexico, which has placed the country as one of the most dangerous places to be a woman. The growth of crimes and the impunity that surrounds them has generated indignation in different sectors of society and has led them to mobilization, one of these actions is “No Estamos todas” translated as 'We are not All Here', which through illustration seek to make visible these violences. Based on the premise that museums have a social function, therefore exhibitions should be active in promoting human rights and gender equality. This article presents an analysis of the exhibits of “No Etamos Todas” from a sociomuseological perspective. These actions took place in November in Portugal and in March in Mexico. Even when they share the same purpose of making the public aware and raising awareness about feminicide and transfeminicide, the languages used in these exhibitions were different, while the first sought to explain the seriousness of the crimes, the second focused on the victims of this violence. These two experiences are analyzed using Pierre Mayrand's exhibition process guide.

Heritage and anthropological concept of culture: a longstanding relationship
Authors: Fuenzalida Maria P. J.
Published: August 2020

This work aimed at discussing the association made between the anthropological concept of culture and the broadening of the scope of the notion of heritage that has occurred since the beginning of the 21st century, specifically with regard to the policies established for the protection of intangible cultural heritage. It has been argued that because it is polysemic, the anthropological concept of culture had been related to the notion of heritage since the first quarter of the 20th century, that is, almost a century before. What has changed is the meaning attributed to both categories. In addition, it was discussed that an expansion of the heritage category is the result of the action of the most diverse social actors in the demand for differential cultural rights, operating with a specific political-cultural grammar, which dynamized enunciations such as multiculturalism, cultural diversity and representation, seeking a non-hierarchical vision of culture, which directly impacted on the conceptualization of heritage and the policy of protection of cultural goods. To this end, as a way of delimiting the discussion, it was decided to work with documents produced by the United Nations Educational, Scientific and Cultural Organization (UNESCO) in the period, since it is a protagonist agent and arena with regard to policies for the protection of cultural goods.

Published: August 2020

Activation of the surface of cotton fabrics before chemical copper plating is proposed to be carried out by applying dispersed copper particles. For this purpose, physical and chemical processes that occur in thin layers of copper chloride solutions under the influence of electromagnetic solar rays of the visible spectrum are used. Initially, copper chlorides interact with cellulose, which is the main component of the tissue, and form copper monochloride. It is shown that this interaction is stimulated by solar rays. After that, the fabric is moistened with a solution of ascorbic acid and again exposed to sunlight. Under the action of photons of solar radiation, electrons in a semiconductor acquire additional energy and restore copper to the elemental state, and the vacancies formed are filled with electrons due to the oxidation of ascorbic acid. As a result of these processes, a film is formed on the surface of the tissue containing copper particles that can catalyze chemical copper plating.

Authors: Youssef Hany M.
Published: August 2020

In the present work, silica nanoparticles functionalized with folic acid (Nano-SiO2-FA) were synthesized and characterized thru elemental analysis, infrared spectroscopy (FT-IR), Brunauer-Emmett-Teller (BET) surface area determination, and scanning electron microscope (SEM). Nano-SiO2-FA was examined as a sustainable and promising sorbent for preconcentration of Al(III) from natural water samples by sorptive-flotation (SF) separation technique before its determination by flame atomic absorption spectrometry (FAAS). A several trials were made in lab, to determine the feasibility of using Nano-SiO2-FA as a sorbent and oleic acid as a surfactant. The influence of: solution pH, temperature, shaking time, surfactant, sorbent and Al(III) concentration and the presence of foreign ions that affect the sorptive-flotation process were investigated. Good results attained under optimum circumstances, at pH 3.5 and ~25�C, according to which nearly 100% of aluminum was separated. The procedure was successfully applied to recover aluminum spiked to some natural water samples. Moreover, a sorption and flotation mechanism is suggested.

Published: August 2020

In this research, a thin film of silver nanowires (AgNWs) is made by varying the number of layers onto a polycarbonate substrate using a spray coating process. AgNWs were obtained via the polyol method using silver nitrate (AgNO3) as rare materials, Polyvinyl pyrrolidone (PVP) as a reducing agent and ethylene glycol (EG) as a solvent. The coating material used is AgNWs solution with a concentration of 10% in ethanol, which has a diameter and length of 176.13 nm and 28.58 �m, respectively. The optical conductivity for third layers were 1.80 � 105 S.m−1,1.98 � 105 S.m−1, and 2.32 � 105 S.m−1 by the gap energy of 3.84 eV, 3.81 eV, and 3.79 eV at a wavelength of 550 nm. The greater the number of layers, the higher the optical conductivity. The smaller energy gap indicates that the material absorbs more energy, so the absorbance value is higher. The sheet resistance of AgNWs thin films in variations of each layer was 119.2 Ω.sq−1, 20.6 Ω.sq−1 and 4.98 Ω.sq−1. The lower the layer resistance, the higher the density of AgNWs and the thicker the layer. Based on the SEM images by cross-section technique, the thickness of AgNWs thin films obtained by 44.244 μm, 69.126 μm, and 100.028 μm for each layer. AgNWs thin films could be used as transparent conductive electrodes for optoelectronic applications.

Refractive errors are the most prevalent ocular disorders in paediatric ophthalmology having a higher occurrence in children with disabilities. This paper evaluated the refractive status of the disabled children and identified the influence of Vitamin D on this status. The study group was represented by 160 children (80 clinically healthy � group 0, 80 having different physical and/or mental disabilities � group 1) with ages between 5-16 years old, ophthalmologically examined between January 2019-January 2020. The prevalence of refractive errors was analysed according to the blood level of Vitamin D; the prevalence of the identified refractive errors was 35% in the group of children with disabilities (16% myopia, 14% astigmatism, 5% hyperopia) and 36% in the group of clinically healthy children (16% astigmatism, 10% myopia, 10% hyperopia). In group 1, an acceptable level (20-30 ng/mL) of Vitamin D was found in 61.54% of children with myopia, 25% in those with hyperopia, and 18.18% in those with astigmatism, the rest showing insufficiency of Vitamin D. Both children with disabilities/clinically healthy shown ocular refractive errors, the difference between the two groups being statistically insignificant (1%). The presence of Vitamin D in the blood in normal or insufficient levels suggests a strong correlation of its levels with the appearance of ocular refraction disorders.

In order to study comparatively the behaviour of the bone-implant interface at mechanical stresses depending on the length of the implant turns, we chose a complex case, a total bimaxillary edentate. 7 implants were virtually inserted into the maxilla (2 pterigoid implants in the lateral regions and 3 implants in the frontal region), and 4 implants were inserted into the mandible (two in the premolar regions and two corresponding to the canines). The FEA analyzes were performed separately for the maxilla and for the mandible, applying a force of 200N on each type of implant. The critical areas, in which the extreme values of the strains develop, are located into the bone on the neck-implant level, and its apex level, regardless of the type of implant and regardless of the maxillary or mandibular area where the implants were virtually inserted. Implants with small turns induce lower stresses and deformations, compared to implants with large turns.

Acute myeloid leukemia (AML) is a malignant hematological disease caused by the abnormal hematopoietic system. Its specific pathogenesis is still unclear. Therefore, we have carried out a series of related studies. Firstly, co-expression analysis of acute myeloid leukemia related genes in the Human Mendelian Genetic Database (OMIM) was carried out, and a co-expression module was constructed. Further enrichment analysis of module-related genes with Go and KEGG was carried out. Subsequently, the modules are analyzed by Crosstalk to show their interaction. Also, pivot prediction is used to identify critical factors in the regulatory module and potential target drugs. Results A total of 14 co-expression modules were obtained, which were found to be significantly involved in cell proliferation and apoptosis, Ras and Wnt signaling pathways. The modules with higher connectivity (UBB, RAC1, TP53, PIK3CA) were also counted. Also, it is found that there is significant crosstalk between these modules. On the other hand, we screened 2815 drivers of regulatory modules, including TP53, E2F1, MYC-based transcription factors, and non-coding RNA (ncRNA) dominated by microRNA-320a, microRNA-193b-3p, and microRNA-93-5p. Finally, many regulatory drugs (Copper, Artenimol, Indomethacin, etc.) with targeted pathogenic genes were predicted. Overall, this study explores the underlying pathogenesis of acute myeloid leukemia and predicts the related regulatory drugs. The results of this study provide a new method and theoretical basis for follow-up mechanism research and treatment strategy.

Holidays have the power to reflect the nation's views, imagination, vision and national values about the scientist and man through artistic images. In addition, holidays form and strengthen feelings such as national pride and national pride, which are composed of such principles as nationhood, popularity, heroism, beauty, grandeur, as well as aesthetic pleasure, aesthetic interest, aesthetic taste and formation of aesthetic ideals – forming a composition of aesthetic perception that distinguishes people from other life events.

In this article, the stages of development of holidays and their artistic and aesthetic features will be studied and studied on a scientific and theoretical basis. Also, the philosophical-aesthetic analysis of the concept of the holiday, the history of its development and scientific-methodological aspects are studied.

Automating creativity assessment with SemDis: An open platform for computing semantic distance
Authors: Beaty Roger E. , Johnson Dan R.
Published: August 2020

Creativity research requires assessing the quality of ideas and products. In practice, conducting creativity research often involves asking several human raters to judge participants’ responses to creativity tasks, such as judging the novelty of ideas from the alternate uses task (AUT). Although such subjective scoring methods have proved useful, they have two inherent limitations—labor cost (raters typically code thousands of responses) and subjectivity (raters vary on their perceptions and preferences)—raising classic psychometric threats to reliability and validity. We sought to address the limitations of subjective scoring by capitalizing on recent developments in automated scoring of verbal creativity via semantic distance, a computational method that uses natural language processing to quantify the semantic relatedness of texts. In five studies, we compare the top performing semantic models (e.g., GloVe, continuous bag of words) previously shown to have the highest correspondence to human relatedness judgements. We assessed these semantic models in relation to human creativity ratings from a canonical verbal creativity task (AUT; Studies 1–3) and novelty/creativity ratings from two word association tasks (Studies 4–5). We find that a latent semantic distance factor—comprised of the common variance from five semantic models—reliably and strongly predicts human creativity and novelty ratings across a range of creativity tasks. We also replicate an established experimental effect in the creativity literature (i.e., the serial order effect) and show that semantic distance correlates with other creativity measures, demonstrating convergent validity. We provide an open platform to efficiently compute semantic distance, including tutorials and documentation (https://osf.io/gz4fc/).

Published: August 2020

Historically, airlines and airports considered air cargo as a by-product. However, by looking for additional sources of revenue, airlines and airports became aware of the potential of air cargo. In this study, the competitiveness of European airports with respect to air cargo will be discussed. The relevant characteristics determining the competitiveness of an airport with respect to air cargo are identified by an extensive literature review and by interviews with industry-specialists. These characteristics can be divided into four different components: territory, air cargo marketplace, airport operations and product differentiation. Each component consists of several factors affecting airport competitiveness for cargo. This study can be used by airports to help assessing and enhancing its air cargo strategy, whereas (potential) shareholders are given an additional instrument to check whether an investment in an airport makes would be viable or not.
SPATIAL PATTERNS OF DOMESTIC AIR PASSENGER TRAFFIC GENERATION IN NIGERIA
Authors: Chukwuka Bardi Emmanuel
Published: August 2020

This study aims at analyzing the spatial patterns of domestic air passenger traffic generated by the interacting city-pairs in Nigeria’s air transportation system at five points in time – 2003, 2006, 2010, 2014 and 2018 to establish the spatial and temporal changes that have taken place over time. It also examined the relationships between the populations of the cities and the volumes of domestic air passenger traffic generated by the cities to establish the impact of population on the traffic generating capacity of the cities. The volumes of domestic air passengers handled by each city, the percentage share of total traffic, the populations of the cities, the Pearson’s Product Moment Correlation Coefficient and the student’s ‘t’ test were used for the analyses. The study revealed that Lagos was the dominant domestic air passenger traffic generation centre. It established that few centres generated most of the domestic air passenger traffic in Nigeria and that the spatial pattern of traffic generation tended more towards concentration than dispersal. The study also found that there were statistically positive relationships between the populations of the cities and the volumes of traffic generated by the cities. Balanced regional development is recommended, among others, to help redistribute population among the cities in the air transportation system in Nigeria so as to increase their air passenger traffic generating capacity.

Explosive Nucleosynthesis in Near-Chandrasekhar Mass White Dwarf Models for Type Iax Supernovae: Dependence on Model Parameters
Authors: Leung Shing-Chi , Nomoto Ken’ichi
Published: August 2020

The recently observed diversity of Type Ia supernovae (SNe Ia) has motivated us to conduct the theoretical modeling of SNe Ia for a wide parameter range. In particular, the origin of Type Iax supernovae (SNe Iax) has been obscure. Following our earlier work on the parameter dependence of SN Ia models, we focus on SNe Iax in the present study. For a model of SNe Iax, we adopt the currently leading model of pure turbulent deflagration of near-Chandrasekhar mass C+O white dwarfs (WDs). We carry out two-dimensional hydrodynamical simulations of the propagation of the deflagration wave, which leaves a small WD remnant behind and ejects nucleosynthesis materials. We show how the explosion properties, such as nucleosynthesis and explosion energy, depend on the model parameters, such as central densities and compositions of the WDs (including the hybrid WDs), turbulent flame prescription, and initial flame geometry. We extract the associated observables in our models and compare with the recently discovered low-mass WDs with unusual surface abundance patterns and the abundance patterns of some SN remnants. We provide the nucleosynthesis yield tables for applications to stellar archeology and galactic chemical evolution. Our results are compared with the representative models in the literature.

We use MMT spectroscopy and deep Subaru Hyper Suprime-Cam (HSC) imaging to compare the spectroscopic central stellar velocity dispersion of quiescent galaxies with the effective dispersion of the dark matter halo derived from the stacked lensing signal. The spectroscopic survey (the Smithsonian Hectospec Lensing Survey) provides a sample of 4585 quiescent galaxy lenses with measured line-of-sight central stellar velocity dispersion (σ

. The independent spectroscopic and weak lensing velocity dispersions probe different scales, ∼3 kpc and ≳100 kpc, respectively, and strongly indicate that the observable central stellar velocity dispersion for quiescent galaxies is a good proxy for the velocity dispersion of the dark matter halo. We thus demonstrate the power of combining high-quality imaging and spectroscopy to shed light on the connection between galaxies and their dark matter halos.
Bayesian Dynamic Mapping of an Exo-Earth from Photometric Variability
Authors: Kawahara Hajime , Masuda Kento
Published: August 2020

Photometric variability of a directly imaged exo-Earth conveys spatial information on its surface and can be used to retrieve a two-dimensional geography and axial tilt of the planet (spin–orbit tomography). In this study, we relax the assumption of the static geography and present a computationally tractable framework for dynamic spin–orbit tomography applicable to time-varying geography. First, a Bayesian framework of static spin–orbit tomography is revisited using analytic expressions of the Bayesian inverse problem with a Gaussian prior. We then extend this analytic framework to a time-varying one through a Gaussian process in the time domain, and present analytic expressions that enable efficient sampling from a full joint posterior distribution of geography, axial tilt, spin rotation period, and hyperparameters in the Gaussian process priors. Consequently, it only takes 0.3 s for a laptop computer to sample one posterior dynamic map conditioned on the other parameters with 3072 pixels and 1024 time grids, for a total of ∼3 × 106 parameters. We applied our dynamic mapping method to a toy model and found that the time-varying geography was accurately retrieved along with the axial tilt and spin rotation period. In addition, we demonstrated the use of dynamic spin–orbit tomography with a real multicolor light curve of the Earth as observed by the Deep Space Climate Observatory. We found that the resultant snapshots from the dominant component of a principal component analysis roughly captured the large-scale, seasonal variations of the clear-sky and cloudy areas on the Earth.
