Fostering the growth of TPACK among international teachers of developing nations through a cultural exchange program
Authors: Dalal Medha , Archambault Leanna , Shelton Catharyn
Published: October 2020

This study investigated the impact of a semester-long technology course as part of a higher education cultural exchange program for secondary school teachers of developing nations. We integrated quantitative data from surveys that evaluated participants’ technological pedagogical content knowledge (TPACK), with qualitative evidence from participants’ technology-based lesson designs. Analysis across the 16 participants indicated that the course was effective in improving teachers’ TPACK. Teachers reported increases in all TPACK domains, with the largest growth in technological content knowledge and TPACK. However, qualitative analysis suggested greater presence of technological pedagogical knowledge. Teachers learned to consider affordances of technology in accordance with content or pedagogy, but their ability was limited due to resource constraints or students’ readiness. Results suggest that international exchange programs are a valuable way to support teachers of developing nations in building educational technology capacity at their home schools.

Implications for practice or policy:

Technology education should leverage teacher expertise in pedagogical content knowledge.

Developers should consider the contexts of home schools when designing education experiences for international teachers.

Continuing education that gives opportunities for hands-on work (active learning) is an effective way to support development of teachers regarding educational technology.
The Impact of Globalization on the Structural Power Control of Developed States in the 1990s and 2000s
Authors: Waichman Shlomo
Published: October 2020

Due to its very nature, globalization undermines the government control. This paper focuses on the impact of globalization on developed states. In particular, it analyzes how globalization has affected each of the following four institutions: (i) governance, (ii) capital markets, (iii) welfare state, and (iv) labor market. This can be summarized as follows: governments have become limited in their decision making, domestic capital markets have transformed into branches of the global market and thus have not been able to freely promote domestic interests, the welfare state serves capitalism rather than protects the society and reduces inequality, and the labor market experiences the migration of workers to developed states, whereas industries moved offshore to developing states.

PIRACTWO MORSKIE I JEGO IMPLIKACJE DLA BEZPIECZEŃSTWA MORSKIEGO W DRUGIEJ DEKADZIE XXI WIEKU – CASUS SOMALII
Authors: Wardin Katarzyna
Published: October 2020

W artykule zaprezentowano i oceniono strategiczne podejście do problemu piractwa morskiego i jego implikacji w kontekście bezpieczeństwa transportu morskiego. Ukazano problem piractwa w najważniejszych regionach jego występowania, intensywność występowania tego problemu w latach 90. XX wieku oraz jego współczesny aspekt. Zaprezentowano i oceniono działania społeczności międzynarodowej w kontekście zwalczania piractwa morskiego oraz pomocy dla państw dysfunkcyjnych na przykładzie Somalii. Artykuł kończy się wnioskami i prawdopodobnym rozwojem omawianego procederu w kolejnych latach, w których Autorka prognozuje, że wdrożone, jak do tej pory działania przyczyniły się do ograniczenia liczby ataków, ale w niewielkim stopniu przyczyniły się do poprawy sytuacji ekonomicznej ludności somalijskiej. W związku z zanotowaniem rosnącej liczby ataków w latach 2015 i 2016, kolejne lata mogą przynieść dalszą falę renesansu piractwa. Jeżeli udzielana pomoc nie zostanie zintensyfikowana i precyzyjniej wykorzystana, to piractwo morskie pozostanie realnym zagrożeniem dla transportu morskiego.
СОВРЕМЕННЫЙ ТЕРРОРИЗМ КАК ПОЛИТИЧЕСКИЙ И ПСИХОЛОГИЧЕСКИЙ ФЕНОМЕН: АКТУАЛЬНЫЕ АСПЕКТЫ ИНТЕРПРЕТАЦИИ
Authors: ГУТОРОВ (Gutorov) Владимир (Vladimir) , ШИРИНЯНЦ (Shirinyants) Александр (Alexander)
Published: October 2020

В статье анализируются основные направления интерпретации феномена терроризма в современной политической науке и политической философии. В общественном сознании терроризм как важнейший фактор современной политики воспринимается, как правило, весьма поверхностно. Многие современные интерпретации терроризма, при всей их кажущейся внешней объективности, на самом деле постоянно воспроизводят трафаретную историческую логику, основанную на чисто внешнем восприятии терроризма как подрывных акций индивидов и небольших групп, руководствующихся самыми различными политическими мотивами. Данная тенденция постоянно используется средствами массовой информации, закрепляющими в политической памяти шаблонные образы террористов и тем самым ложное восприятие как истинных целей, которые они преследуют, так и тех реальных корпоративных структур, которые финансируют и направляют их деятельность. Повсеместно возникающие дилеммы в трактовках террористической активности в различных регионах мира связаны с господством в современном политическом дискурсе практик насилия, несвободы и чрезвычайных ситуаций, постоянно подпитывающих риторику «войны с террором». Эти практики сами по себе накладывают ограничения на субъективную свободу суждений, способствуя формированию структур «дисциплинарной власти», основные механизмы которой были в свое время всесторонне исследованы в политической философии М. Фуко. В статье обосновывается тезис, согласно которому вопреки устойчивым либеральным стереотипам, государственный терроризм следует рассматривать в теоретическом плане в качестве универсальной основы или «матрицы», в то время как все другие формы индивидуального и группового терроризма, независимо от их социальной, классовой или идеологической ориентации, являются производными от данной основы. В статье отмечается, что адекватные научные определения терроризма способствуют разрушению некоторых историософских концепций, которые в последние десятилетия превратились в устойчивые политические мифы.
COMMERCIAL DIPLOMACY IN A GLOBALIZED WORLD
Authors: Villanueva Lop Guillermo
Published: October 2020

The beginning of 21st century has witnessed the consolidation of a process of globalization, where since the 1980s the hegemonic position of the United States has weakened and the international environment is moving towards a multipolar system with emerging economies adopting an increasing power. In this context, new non-state actors, such as non governmental organizations or multinational firms, have adopted an important role in the stage of international relations that in the past was limited to states and international organizations. The globalization process forced firms to operate internationally, and the financial crisis started in 2008 provoked the contraction of domestic markets and obliged governments and many firms from industrialized economies to look beyond the limits of their home states if they wanted to survive and benefit from the enormous opportunities offered by the new potential foreign markets. In order to achieve this, both governments and multinational firms should adapt diplomacy and its capabilities to their own specific needs. Commercial diplomacy includes policies, practices, instruments and organizational structures that governments and multinational firms should adopt at different levels to survive in today’s rapidly changing global business environment. Only by interacting between them and with the rest of actors within the international sphere, states and multinational firms will benefit from the switch in the balance of economic power.

Ku wolności wyzwolił nas Chrystus (Ga 5,1). Teologiczne aspekty ludzkiej wolności
Authors: Królikowski Janusz
Published: October 2020

The discovery of universal freedom is an achievement of Saint Paul, and an achievement of the Church is a consequent propagation of this fact throughout the centuries. The Christian character of this discovery was already noticed by Hegel. In today’s world, so strongly marked by the search of freedom it is necessary to reiterate the Christian vision of freedom which is a universal one. This vision is profoundly theological in character and deeply rooted in the mystery of redemption brought by Jesus Christ. This article touches upon this fact and points out its certain aspects, especially the soteriological one. Bearing in mind the theology of freedom we cannot ignore its abundant anthropological references. The article recalls the proposition of St. Thomas Aquinas, which has been largely accepted by Catholic theology and constitutes a benchmark of anthropological philosophy which has a special application in ethics. Christian tradition stresses the fact that for a human, freedom is above all “a vocation”. Therefore, on the one hand God’s definite design through Jesus Christ concerning man has to find its eschatological realization, on the other hand man’s freedom which is solidifying in this design has to revel and show itself to the full. Undoubtedly, the eschatological issue in Christian vision of freedom is worth mentioning as well.
Problematyka programów nauczania religii w szkole powszechnej i gimnazjum ogólnokształcącym na łamach „Miesięcznika Katechetycznego i Wychowawczego” w latach 1932-1939
Authors: Ceglarek Roman
Published: October 2020

The educational changes launched in Poland in 1932 included the establishment of new types of schools, such as seven-year common schools and four-year middle schools. Therefore, there was a need for school curricula that would correspond to the new educational system. The National Board of Education first prepared the preliminary drafts and subsequently passed the school curricula. The Catechetic and Pedagogical Monthly analyzed them over the span of the 1930s. Not only the analyses and their results were published in the magazine, but also the contents of the curricula. That is why in pre-war Poland this Catholic periodical became one of the most important information sources on school curricula of religious education. Moreover, it was a source from which successive syllabuses were derived.

Do all dogs go to heaven? Tracking human-animal relationships through the archaeological survey of pet cemeteries
Authors: Tourigny Eric
Published: October 2020

Pet cemeteries provide a unique opportunity to investigate the development of human-animal relationships, yet few archaeological studies of these cemeteries have been undertaken. This article presents an archaeological survey of gravestones at British pet cemeteries from the Victorian period to the present. These memorials provide evidence for the perceived roles of animals, suggesting the development of an often conflicted relationship between humans and companion animals in British society—from beloved pets to valued family members—and the increasing belief in animal afterlives. The results are discussed in the context of society's current attitude towards animals and the struggle to define our relationships with pets through the mourning of their loss.
Turkish Get-Up: Correcting Common Kinematic Errors and Translating Movements to More Complex Lifts
Authors: Collum Connor , Weeks Macy , Schnetzer Allyson , Snarr Ronald L.
Published: October 2020

The Turkish get-up (TGU) is a functional strength exercise that focuses on the quality of the movement as opposed to the shear strength or speed. Proficiency in this movement may improve shoulder and hip strength, stability, and flexibility, which can be beneficial when performing more complex lifts (e.g., deadlift, clean, and overhead press). However, performing this movement without proper technique can lead to kinematic errors and increased risk of injury. This article analyzes the common errors during the TGU and corrective exercises that may translate to improved execution of more complex exercises, ultimately enhancing performance.
The Impact of Pathological Narcissism on Affect Following Social Rejection
Authors: Sasso Scott , Cain Nicole M. , Meehan Kevin B. , Zeng Ruifan , Wong Philip S.
Published: October 2020

Previous research has shown that narcissism is associated with interpersonal difficulties and maladaptive affective responses to social rejection. In the current studies, the authors examined two phenotypes of pathological narcissism, narcissistic grandiosity and narcissistic vulnerability, and their impact on individuals' affective responses in two distinctive social rejection paradigms. Participants from Study 1 (N = 239), recruited from a multicultural university and Amazon's Mechanical Turk, completed Cyberball, a computerized social rejection paradigm. Participants from Study 2 (N = 238) were recruited from a multicultural university and participated in an in vivo group rejection paradigm in a laboratory. Results indicated that following the rejection in both studies, narcissistic vulnerability positively predicted explicit negative affect and state anger. In addition, the positive relationship between narcissistic vulnerability and explicit negative affect was moderated by greater implicit negative affect in Study 2. The implications and limitations of these findings are discussed.

Precise information on synapse organization in a dendrite is crucial to understanding the mechanisms underlying voltage integration and the variability in the strength of synaptic inputs across dendrites of different complex morphologies. Here, we used focused ion beam/scanning electron microscope (FIB/SEM) to image the dendritic spines of mice in the hippocampal CA1 region, CA3 region, somatosensory cortex, striatum, and cerebellum (CB). Our results show that the spine geometry and dimensions differ across neuronal cell types. Despite this difference, dendritic spines were organized in an orchestrated manner such that the postsynaptic density (PSD) area per unit length of dendrite scaled positively with the dendritic diameter in CA1 proximal stratum radiatum (PSR), cortex, and CB. The ratio of the PSD area to neck length was kept relatively uniform across dendrites of different diameters in CA1 PSR. Computer simulation suggests that a similar level of synaptic strength across different dendrites in CA1 PSR enables the effective transfer of synaptic inputs from the dendrites toward soma. Excitatory postsynaptic potentials (EPSPs), evoked at single spines by glutamate uncaging and recorded at the soma, show that the neck length is more influential than head width in regulating the EPSP magnitude at the soma. Our study describes thorough morphologic features and the organizational principles of dendritic spines in different brain regions.
Long-term facial changes and clinical correlations in patients with treated acromegaly: a cohort study
Authors: Du Fengzhou , Chen Qiao , Wang Xiaojun , Guo Xiaopeng , Wang Zihao , Gao Lu , Long Xiao , Xing Bing
Published: October 2020

Background

Facial abnormality is the most significant feature in acromegaly patients. However, it is unclear whether and how patient facial appearance improves after treatment. This study aimed to identify 3D facial changes in acromegaly patients after surgical treatment.

Methods

This study included 30 acromegaly patients who underwent resection of a pituitary GH adenoma. The location and extent of facial changes were identified by comparing baseline and 2-year follow-up 3D images of the face. Relationships between facial changes and GH and IGF-1 were evaluated with simple or multivariable linear regression models.

Results

Significant soft tissue improvements were observed in acromegaly patients with complete remission, especially in the nose and lip region. Significant reductions in nasal width (3.46 mm, P < 0.001), tip protrusion (1.18 mm, P = 0.003), face curve length (3.89 mm, P = 0.004) and vermilion area (1.42 cm3, P = 0.001) were observed at the 2-year follow-up. Further, changes in nasal width were associated with decreases in GH (β = 4.440, P = 0.017), the GH nadir (β = 4.393, P = 0.011) and IGF-1 (β = 5.263, P = 0.002). The associations were maintained after adjusting for confounders.

Conclusions

Acromegaly patients achieved considerable facial improvements after surgical treatment. The change in nose width was associated with GH and IGF-1 decrease. Better control of patient hormone levels after surgery improves patient facial recovery.
Leveraging Multiple Layers of Data To Predict Drosophila Complex Traits

Published: October 2020

The ability to accurately predict complex trait phenotypes from genetic and genomic data are critical for the implementation of personalized medicine and precision agriculture; however, prediction accuracy for most complex traits is currently low. Here, we used data on whole genome sequences, deep RNA sequencing, and high quality phenotypes for three quantitative traits in the ∼200 inbred lines of the Drosophila melanogaster Genetic Reference Panel (DGRP) to compare the prediction accuracies of gene expression and genotypes for three complex traits. We found that expression levels (r = 0.28 and 0.38, for females and males, respectively) provided higher prediction accuracy than genotypes (r = 0.07 and 0.15, for females and males, respectively) for starvation resistance, similar prediction accuracy for chill coma recovery (null for both models and sexes), and lower prediction accuracy for startle response (r = 0.15 and 0.14 for female and male genotypes, respectively; and r = 0.12 and 0.11, for females and male transcripts, respectively). Models including both genotype and expression levels did not outperform the best single component model. However, accuracy increased considerably for all the three traits when we included gene ontology (GO) category as an additional layer of information for both genomic variants and transcripts. We found strongly predictive GO terms for each of the three traits, some of which had a clear plausible biological interpretation. For example, for starvation resistance in females, GO:0033500 (r = 0.39 for transcripts) and GO:0032870 (r = 0.40 for transcripts), have been implicated in carbohydrate homeostasis and cellular response to hormone stimulus (including the insulin receptor signaling pathway), respectively. In summary, this study shows that integrating different sources of information improved prediction accuracy and helped elucidate the genetic architecture of three Drosophila complex phenotypes.

Мета: визначити особливості функціональних порушень кульшових суглобів, що сформувались внаслідок дисплазії у дітей дошкільного віку.

Матеріал і методи: у дослідженні, яке проводилося протягом 2014–2019 рр., взяла участь 131 дитина дошкільного віку (середній вік 5,6±0,5 років). Учасників було поділено на дві групи: основну (ОГ, n=68) – діти з односторонньою ДКС за анамнезом (виявлено за результатами аналізу медичних карт) та групу порівняння (ГП, n=63) – діти без порушень з боку кульшових суглобів. Для оцінки результатів використано метод тензодинамометрії (мануальний м’язовий тестер на базі датчика механічного зусилля “EXPANDER”) та метод гоніометрії.

Результати:результати дослідження показників електротензодинамометрії м’язів нижніх кінцівок у дітей ОГ свідчать про достовірне зниження сили м’язів-абдукторів стегна (m. gluteus medius, m. gluteus minimus, m. tensor fasciae latae) ушкодженої кінцівки відносно інтактної у кульшовому суглобі (інтактна – 85,8±6,8 та уражена 54,5±4,9 ( ±S), (p ≤0,05)) та гіпертонус м’язів-аддукторів стегна (m. gracilis, m. adductor longus, m. adductor brevis) з боку ураженої кінцівки відносно інтактної кінцівки (інтактна – 68,2±4,4, уражена – 95,8±4,1, ( ±S), (p ≤0,05). Під час вивчення показників тензодинамометрії у дітей з ДКС виявлено сильний прямий кореляційний взаємозв’язок між станом м’язового апарату і розвитком привідної контрактури кульшового суглоба (коефіцієнт кореляції між показниками сили м’язів-абдукторів стегна та амплітудою відведення – r = 0,7 (сильний зв’язок, p < 0,05).

Висновки: тензодинамометричне дослідження м’язів дало можливість виявити зниження тонусу м’язів-абдукторів стегна, biceps femoris, m. semitendinosus, m. semimembranosus, m. quadriceps femoris, m. sartorius. Результатом дисбалансу функціональної активності м’язів є формування торсійно-вальгусної деформації кульшового суглоба, яка вимагає поетапного індивідуального проведення реабілітаційно-корекційних втручань.

Мета: визначити динаміку показників техніко-тактичних дій (одноборства) команди «Металіст-1925» у Чемпіонаті України за 10 календарних ігор на своєму полі.

Матеріал і методи: теоретичний аналіз і узагальнення даних науково-методичної літератури, методи педагогічних спостережень, методи математичної статистики. Реєстрація та аналіз техніко-тактичних дій (одноборства) здійснювалися в іграх Першості України в першій лізі команди «Металіст-1925». Було проаналізовано 10 ігор, що відбулися у м. Харків.

Результати:визначена динаміка кількісних і якісних показників техніко-тактичних дій (одноборства) команди Металіст-1925 за 10 ігор Чемпіонату України за перший та другий тайми протягом 15 хвилинних відрізків. За перший тайм командою «Металіст-1925» було виконано 54 техніко-тактичних дії, з них 57 з негативним показником, коефіцієнт браку склав – 37%. Кількість одноборств у другому таймі склала 192, з яких 100 з негативним показником, коефіцієнт браку склав – 58,3%, що значно вище, ніж у першому таймі. Це, в першу чергу, пояснюється тим, що у другому таймі накопичується втома, тому гравці частіше допускають помилки. Аналізуючи динаміку техніко-тактичних дій (одноборства) за 15 хвилинні відрізки, можна зробити висновок, що найбільша кількість одноборств за 10 ігор була виконана гравцями у період з 76 по 90 хвилину (71 дія), а найменша кількість була виконана з 1 по 15 хвилину (37 дій). Найбільша кількість негативних дій була зареєстрована з 46 по 60 хвилину (35 дій), де коефіцієнт браку склав 60,3 %, а найменша кількість з 1 по 15 хвилину (11 дій), де коефіцієнт браку склав 27,9 %.

Висновки: отримані кількісні та якісні показники техніко-тактичних дій (одноборства) гравців команди «Металіст-1925» у Чемпіонаті України в більшості ігор не відповідають еталонним моделям висококваліфікованих футболістів, що дає підставу для корегування навчально-тренувального процесу.

Creating Ethical Research Partnerships – Relational Accountability in Action
Authors: Henry Robert , Tait Caroline , UP STRAIGHT
Published: October 2020

Research that focuses on Indigenous street gangs is primarily derived from the experiences and expertise of individuals who work in the criminal justice system or community-based organizations and not street gang members themselves (Grekul & LaRocque, 2011). The primary reason for this is that it is difficult to build research relationships with individuals who, for the majority of their lives, have tried to keep their lives hidden from those who they consider as outsiders. However, it is these narratives of those who have been directly involved with street gangs that provide the greatest insight into what attracts individuals to join, the realities of street gang life, and what is needed to support individuals to exit street gangs. The current article examines how relational accountability framed within the 4Rs (Kirkness & Barnhardt, 1991) was used to engage in a photovoice research project that focused on how Indigenous male ex-gang members came to construct their notions of masculinity within local street gangs. To engage the men in the research, relationships were built with STR8 UP, a community-based gang intervention program located in Saskatoon, Saskatchewan. By building relationships, the foundational components to Indigenous research, trust between researcher and participants was established where modifications within the research methods could occur to engage the men’s participation more fully. The current article also examines the importance of critical reflexivity within relational accountability, as it provides researchers with a tool to understand their social privileges and how this can impact the research process

The project has created resources that are culturally relevant, appropriate, and accessible to Inuit patients and the healthcare providers working with them. Not only are we helping to educate and empower Inuit patients and their families, but also better educating healthcare providers around the importance of cultural knowledge in cancer care. Our ultimate goal is to improve health outcomes by increasing awareness and understanding of cancer among Inuit communities. This project is a collaboration between Pauktuutit Inuit Women of Canada and the Canadian Cancer Society. It highlights how partnerships with organizations, both big and small, and connected with the community, can have a real impact.
On the effect of the meridional contour shape on the power characteristics of a centrifugal compressor wheel

This work is concerned with the development of approaches to the optimal aerodynamic design of centrifugal compressor wheels, which is due to the use of centrifugal stages in compressors of modern aircraft gas turbine engines and power plants. The aim of this work is a computational study of the effect of the meridional contour shape of a centrifugal compressor wheel on its power characteristics. The basic method is a numerical simulation of 3D turbulent gas flows in centrifugal wheels on the basis of the complete averaged Navier¬–Stokes equations and a two-parameter turbulence model. The computational study features: varying the shape of the hub and tip part of the meridional contour over a wide range, formulating quality criteria as the mean integral values of the wheel power characteristics over the operating range of the air flow rate through the wheel, and a systematic scan of the independent variable range at points that form a uniformly distributed sequence. As a result of multiparameter calculations, it was shown that in the case of a flow without separation in the blade channels of a wheel with a given starting shape of the meridional contour, varying that shape has an insignificant effect on the wheel power characteristics. It is pointed out that in similar cases it seems to be advisable to aerodynamically improve centrifugal wheels by varying the shape of their blades in the circumferential direction rather than in the meridional plane. This conclusion was made using rather a “coarse” computational grid, which, however, retains the sensitivity of the computed results to a variation in the centrifugal wheel geometry. On the whole, this work clarifies ways of further aerodynamic improvement of centrifugal compressor impellers in cases where the starting centrifugal wheel is a well-designed wheel with a flow without separation in the blade channels. The results obtained may be used in the aerodynamic optimization of centrifugal stages of aircraft gas turbine engines.
On the choice of a parking orbit for a service spacecraft
Authors:   Institute of Technical Mechanics of the National Academy of Sciences of Ukraine and the State Space Agency of Ukraine, Holdshtein Yu.M.
Published: October 2020

At present, the requirements for increasing spacecraft active life and operational reliability and reducing spacecraft operation costs become more and more stringent. Because of this, on-orbit servicing becomes more and more attractive. One of the most promising ways to increase the efficiency of transport operations in space is to carry out on-orbit servicing using reusable spacecraft with low-thrust solar electrojet engines. The aim of this paper is to develop a mathematical model for the choice of an optimal low near-Earth parking orbit for a reusable service spacecraft. The case of noncoplanar near-circular orbits of spacecraft and a shuttle scenario of their servicing is considered. The solution of the problem of choosing an optimal parking orbit for a reusable service spacecraft involves repeated solutions of the problem of determining the delta-velocity of the service spacecraft’s orbital transfers between its parking orbit and the orbits of the serviced spacecraft. In this connection, using the averaging method, a mathematical model is developed for the analytical determination of orbital transfer program controls and trajectories and assessing orbital transfer energy expenditures. With its use, a mathematical model is developed for the choice of a service spacecraft’s optimal parking orbit. The objective function is the total delta-velocity of the service spacecraft’s orbital transfers from its parking orbit to the orbits of the serviced spacecraft and vice versa with the inclusion of the orbital transfer frequency. The optimizable parameters are the service spacecraft parking orbit parameters. The use of the proposed models is illustrated by an example of service spacecraft parking orbit optimization. What is new is the mathematical models developed. The results obtained may be used in the preliminary planning of on-orbit servicing operations.

Lviv is a city with a centuries-old history that is easy to adapt to introduce a new direction in tourism for Ukraine - urban geotourism. Urban geotourism is an innovative form of tourism, the basis of which is the use of objects of modern cities for the promotion of geology, educational activities and tourism business needs. Lviv is a city with high geotourist potential due to its unique geomorphological, geological position, well-developed tourist infrastructure, good information support and a large concentration of unique easily accessible diverse geo-tourist objects. The study of urban geosites for the needs of geotourism, the study of potential objects illuminating the interconnection of geology and architecture in the development of the historical urban landscape in Lviv have only just begun. Currently, there is a summarized short characteristic of the urbanistic complex of Lviv’s geotourist sites and their classification was developed. They are divided into two supergroups (natural, anthropogenic), four groups (natural formations, natural processes, geotourism trails, natural-cultural, mining), two subgroups (polytypic, monotypic), 11 types and 19 categories. The geotourist sites of Lviv have scientific, cognitive, culturalaesthetic value, are easily accessible, important for the educational process and in the case of their popularization will become attractive geo-tourist attractions. They are an important link for restoring Earth’s history, exhibiting the geological structure of Lviv’s territory, demonstrating new approaches to geotourism that combine nature, history and culture. Their study will allow the geomorphological and geological features of the city to be shown , allow us to get acquainted with the history of geological development, and help draw attention to the stone material used in the organization of urban space. Combining stone monuments with the cultural and tourist aspect is a great approach for disseminating geological knowledge.

Useful information was obtained about the environmental condition of this region such as energy, sediment location, origin, sediment carrying path, pond evolutionary process, and tectonic conditions and origins of sediments by studying physical and geochemical sediment changes processes in place and time, distribution of sediments and elements in lagoon bed, and also identification the effective factors on sediment distribution model. In this regard, 59 sediment samples were taken from Siyah Keshim lagoon and were analyzed chemically and aggregation by XRF and ICP-MS technic. Adaptation of data by Folk diagrams showed that this region is placed in a range of sand, muddy sand, sand with a little gravel, muddy sand with a little gravel, and silty sand. Weak to medium sorting and negative tilting shows sediment in a coastal area. Geochemical evidence shows that SiO2/Al2O3 ratio in these sediments is 2.6-3.7. In addition, Na2O value shows relatively low sediment investigation for sediments of this lagoon. Moreover, determination of the weathering effect in origin place by the chemical index of alteration (CIA) and chemical weathering index (CWI) shows intensive chemical alternation on sediments. Index of combined variety was averagely 1.54 in the studied sediments and show that sediments resulted from the first cycle sediment. Using tectonic separating diagrams based on the primary and secondary oxidants percentage show the sediment in the active continent margin (ACM), continent-island arc (CIA), and oceanic island arc (OIA) and shows that the studied sediments are related to subduction margin.

The article is devoted to the problem of constructing the optimal transport route of a bus excursion tour of a tour operator according to the minimal length criterion. Transportation expenses are an important part of a bus tour cost, and their minimization is a required condition for route development and planning. To solve this problem, the authors used the tour route calculating method as a kind of transport task, namely the task of the salesman. To solve this problem, one of the varieties of the transport problem, namely the salesman traveling problem, is applied. The essence of the traveling salesman problem is to find the shortest route between cities, if the distances between them are known. The beginning of the route and its end coincide, that is, the route is cyclic. The most popular in Ukraine sightseeing tours of tour operators to the Transcarpathian region are taken for the optimization. A mathematical model of the traveling salesman problem is made to construct an optimal transport route. The solution was found using the Microsoft Excel’s Solver add-in application program package. To solve the problem by this method, it was reduced to a special form and additional variables were introduced. The analysis helped the tour operator to check the existing sightseeing bus routes by the minimal length criterion. The results allowed making assumptions about the need to change some popular routes of Ukrainian tour operators in order to reduce transport costs. The method of bus tours evaluation of tour operators according to the minimal length criterion allows to check the tourist transportation optimality while planning the route and developing their own tourist product. The introduction of modern digital technologies and software to optimize the territorial organization of tourist routes is proposed, which will help tour operators of Ukraine in the design of bus tourist trips to nature and recreational locations in tourist regions. The development of an optimal model for the transportation of tourists on the highways and the reduction of their costs for consumption of transport services will contribute to the development of tourist trips in Ukraine. The necessity of using methods of geolocation of tourist resources for the construction of routes for visiting natural and cultural-historical monuments and tourist centers has been determined. The application of the proposed method will allow tour operators to reduce transport costs and, as a consequence, the total cost of the tourist product.

Published: October 2020

Based on a rigorous analysis of fish collections of the Instituto Amazónico de Investigaciones Científicas (Sinchi) and new collections by us, we report new Colombian records and geographical range extensions for freshwater fish species. The new occurrences include representatives of four taxonomic orders, eight families, and 13 genera. Our findings expand the geographic ranges of fish species within the Amazon and Orinoco basins and include species reported from Colombia for the first time. This information is fundamental for completion of species inventories, as well as analyses of freshwater fish diversity patterns at macroecological scales. In addition, our data provide useful information for the formulation of strategies for the conservation, management, and sustainable use of biodiversity.

A novel antibacterial strategy: histone and antimicrobial peptide synergy
Authors: Duong Leora , Gross Steven P. , Siryaporn Albert
Published: October 2020

The rate at which antibiotics are discovered and developed has stagnated; meanwhile, antibacterial resistance continually increases and leads to a plethora of untreatable and deadly infections worldwide. Therefore, there is a critical need to develop new antimicrobial strategies to combat this alarming reality. One approach is to understand natural antimicrobial defense mechanisms that higher-level organisms employ in order to kill bacteria, potentially leading to novel antibiotic therapeutic approaches. Mammalian histones have long been reported to have antibiotic activity, with the first observation of their antibacterial properties reported in 1942. However, there have been doubts about whether histones could truly have any such role in the animal, predominantly based on two issues: they are found in the nucleus (so are not in a position to encounter bacteria), and their antibiotic activity in vitro has been relatively weak in physiological conditions. More recent studies have addressed both sets of concerns. Histones are released from cells as part of neutrophil extracellular traps (NETs) and are thus able to encounter extracellular bacteria. Histones are also present intracellularly in the cytoplasm attached to lipid droplets, positioning them to encounter cytosolic bacteria. Our recent work (Doolin et al., 2020, Nat Commun), which is discussed here, shows that histones have synergistic antimicrobial activities when they are paired with antimicrobial peptides (AMPs), which form pores in bacterial membranes and co-localize with histones in NETs. The work demonstrates that histones enhance AMP-mediated pores, impair bacterial membrane recovery, depolarize the bacterial proton gradient, and enter the bacterial cytoplasm, where they restructure the chromosome and inhibit transcription. Here, we examine potential mechanisms that are responsible for these outcomes.

Published: October 2020

Polyacrylamide ferrogels with embedded magnetic nanoparticles of metallic nickel (Ni) and nanoparticles of nickel coated with a carbon shell (Ni@C) were synthesized by radical polymerization in water. The effect of the carbon shell on the interaction of Ni and Ni@C nanoparticles with polyacrylamide matrix and on swelling ratio of the ferrogels has been studied. The deposition of carbon on the surface of Ni nanoparticles worsens their interaction with polyacrylamide but at the same time elevates the water uptake by ferrogels.
