Sexual dimorphism of the body size of a multicolored lizard in the south-eastern Lower Volga
Authors: Mishustin Stanislav S. , Polynova Galina V.
Published: January 2022

The investigation in the population structure of the western subspecies of the multicolored lizard ( Eremias arguta deserti Gmelin, 1789) was carried out in semi-deserts of the Lower Volga region. The purpose of the study was to find out the features of the population morphometric data. The main research methods: measuring the length of the trunk and tail with an accuracy of up to a millimeter, statistical data processing using the Kolmogorov - Smirnov test in the STATISTICA 12 program. Statistical analysis showed the presence of sexual dimorphism in the population in terms of body parameters: the length of the tail of males is significantly greater than that of females. The calculation of the statistical significance of the differences between the average length of the trunk and the length of the tail confirmed that males and females have longer tails than the trunk. Yet sexually mature males and females do not differ significantly from each other in terms of body size. At the same time, females have a certain variability of morphometric data, which serves as one of the main indicators of intra-population variability.
Study of the role of natural and anthropogenic factors in the formation of water quality in small rivers on the example of the Veletma river in the Nizhny Novgorod region
Authors: Smirnova Maria V. , Batanina Anastasia I.
Published: January 2022

Small rivers of Central Russia often experience a high anthropogenic pressure, and at the same time their study and measures taken to preserve them are incomparably more modest than for large rivers. On the example of the Veletma river in the Nizhny Novgorod region, the factors affecting the formation of the water quality of the small river are considered. The ecological and geographical characteristics of the Veletma river are given. It is shown that the current methodology for assessing the water quality of large rivers by the Specific Combinatorial Water Pollution Index does not allow to determine what is the contribution of anthropogenic pressure to the deterioration of water quality, and what is the contribution of natural factors. Studies of a number of physical and chemical characteristics of the waters of the Veletma river have shown that on a short section of the river, which is less than 400 m, there are significant changes in the physical and chemical composition of water, reaching 45-95%. Such significant changes are associated on the one hand with the influence of the treatment facilities of the city of Navashino, and on the other hand, with the special location of the lake Zelenoe in the path of the river. Satellite images of the Veletma's confluence with the lake Zelenoe show the plume. It is suggested that the lake is characterized by the same processes that take place in the confluence of large and medium-sized rivers into the seas and lakes, called marginal filter, in which not only suspended but also dissolved impurities are retained. This fact is confirmed by laboratory studies.

Published: January 2022

The possibility of utilization of overburden rocks of the Chernovsky brown coal and Baleysko-Taseevsky gold occurrences (Trans-Baikal Region) in the road construction industry is studied. Polymeric additives Cryogelite and StabOL were chosen as stabilizing additives in the compositions of road-building composites. The initial mineral samples were examined by methods of atomic emission spectrometry with inductively coupled plasma, powder diffraction, and infrared spectroscopy. It was found that the introduction to formulation of composites with use of overburden rocks of 8 wt. % Portland cement and 10 wt. % fly ash, as well as stabilizing additives Cryogelit (Chernovskoe occurrence) and StabOL (Baleysko-Taseevskoe occurrence), allows to obtain samples with strength grade M40 and frost resistance grade F15. The biotesting method proved that the obtained composites do not have an acute toxic effect on test objects and are safe for the environment and human health.
Environmental disciplines taught to foreign students participating short term exchange programs in RUDN University: experience and approach
Authors: Ledashcheva Tatyana N. , Pinaev Vladimir E.
Published: January 2022

The article examines experience and approaches of teaching to foreign students who came to the Institute of Environmental Engineering of the RUDN University for short-term exchange programs (2-3 months). The short duration of the exchange programs imposes additional restrictions on the order of studying the material - it is necessary to give an idea not only about the requirements of environmental protection legislation applied, for example, in Russia and the European Union, but also to give students the opportunity to actively participate in the classes during the workshops, taking into account the adaptation period when in their thoughts they are still at home, but are already in the host country. As an example, the courses conducted at the RUDN for students from Indonesia who arrived to participate the program Sustainability management and studying Environmental Impact Assessment and Management of Environmental Risks courses. The experience of teaching these disciplines shows the expediency of practical tasks related to the homeland of students - this allows them not only not to miss their homeland, but also to study in more detail the requirements of their country legislation related impact assessment on the environment, but also the impact of various types of industries on the environment. Thus, the students not only does not fall out of the educational context in home country for several months, but also independently receive more in-depth knowledge. As an exam at the end of the course, it is advisable not to give a traditional test with questions, but to prepare a project that can be carried out jointly with colleagues who have remained at the university in their homeland and allows applying the knowledge gained through the exchange program to create a visually evaluated result (project) on environmental protection in their homeland.

Konsepsi Demokrasi Menurut Al-Qur'an
Authors: Bahri Samsul Bahri , Nurkhalis Nurkhalis , Rizki Muhammad
Published: January 2022

Demokrasi dipahami sebagai sistem di mana warganya bebas mengambil keputusan berdasarkan suara mayoritas. Demokrasi merupakan salah satu sistem pengelolaan kekuasaan yang dipandang paling cocok untuk diterapkan di negara-negara modern dewasa ini. Sebagai sumber petunjuk bagi manusia, al-Qur’an tentu tidak membiarkan umatnya mengalami kebuntuan dalam menemukan konsepsi mengenai sistem penyelenggaraan kekuasaan. Konsepsi mengenai demokrasi dengan demikian diyakini terakomodasi dalam al-Qur’an. Atas dasar itu, permasalahan utama yang perlu dicarikan jawabannya adalah, bagaimanakah konsepsi demokrasi dalam al-Qur’an? Tulisan ini berupaya mengeksplorasi ayat-ayat al-Qur’an untuk menemukan jawaban yang diharapkan. Data untuk tulisan ini dikumpulkan dengan mengikuti langkah-langkah pengumpulan data dalam tafsir mawḍṻ’i, terutama langkah kedua dan ketiga. Data berupa ayat-ayat al-Qur’an tersebut dianalisis dengan mengikuti langkah-langkah selanjutnya dalam tahapan penafsiran secara tematik tersebut. Hasil analisis menunjukkan bahwa terma al-Qur’an yang merepresentasikan makna demokrasi adalah syūrā. Dalam syūrā ditemukan norma yang mengatur keharusan melakukan musyawarah dalam urusan-urusan duniawi, baik urusan keluarga, muamalah, maupun urusan bidang politik. Konsep demokrasi dalam bentuk syūrā disebutkan dalam QS. al-Baqarah (2): 233, QS. Āli ‘Imrān (3): 159, dan QS.al-Syūrā (42): 38. Terdapat tiga poin hubungan ayat-ayat al-Qur’an tentang demokrasi dan demokrasi masa kini. Pertama, kewajiban melakukan temu pendapat dan melarang diktator. Kedua, kebebasan mengeluarkan pendapat. Ketiga, menghargai pendapat yang lebih unggul dari hasil musyawarah. Keempat, suara mayoritas diperhitungkan dengan melindungi hak-hak minoritas.
Moscow and Petersburg in Tolstoy’s “War and Peace”
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Shcherbakov Viktor I.
Published: January 2022

Moscow and St. Petersburg have repeatedly become the subject of comparative characterization in Russian literature. Leo Tolstoy in his novels also tried to outline and compare the characters of two Russian megacities, traditionally competing with each other. In “War and Peace”, Moscow is depicted in detail and with love, while St. Petersburg is shown schematically and aloof. The comparison of two capitals is extremely contrasting here — “de salon” Petersburg and “people’s” Moscow are presented as antipodes and remain so during the Napoleonic invasion. The article clarifies ideological and psychological roots of this mythologeme. It is shown that it is based on both objective historical reasons (the vigorous development of St. Petersburg in the 19th century and the lag of Moscow, which then had the appearance of a “provincial” city), and Tolstoy’s deeply personal sympathies and antipathies, to which he strove to impart a universal character.
Concerning the World Harmony and the Human Debt in the Epic Novel “War and Peace” (Symbolism of Petya Rostov’s Premortal Dream)
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Pavlova Irina B.
Published: January 2022

The article is related to the issue of the highest expediency of the world order, the organic connection between the earthly and the heavenly, the musical harmony of the universe and the purpose of man, the moral duty of an individual and all mankind on the example of analyzing Petya Rostov’s dreamy vision before his death. The dreams of a young hero are a revelation associated with the issues of the universe, they become omens to the lesion of dark, destructive elements and victories of ordering and beauty over evil and ataxia. The salvation of Russian people became possible with the spiritual union of the nation, the awakening of the “swarm” principle. This fragment of the epic novel clearly reflected the artist’s cosmology, which is close to the ideas of ancient Greek philosophy, the teachings of the Pythagoreans, Plato, and the ethical views of the founder of German classical philosophy I. Kant. In the events of the Patriotic War of 1812, the writer saw the manifestation of those patterns that, from his point of view, govern the universe, the predetermined course of history, the triumph of the correct world order.

Published: January 2022

La infraestructura vial es uno de los entes más importantes en el desarrollo económico de una región, ya que permite el traslado de bienes y servicios de un territorio a otro, sin embargo, este sector genera grandes afectaciones en el medio ambiente, representados en emisiones, consumo de energía y contaminación. Por tal motivo, en la actualidad se han implementado algunas alternativas sostenibles que permitan la construcción/ mantenimiento de vías de una manera amigable con el medio ambiente, una de ellas es la utilización de Asfalto Natural “MAPIA” para el mantenimiento de vías, sin embargo, al ser un material compuesto por poco contenido de asfalto y bastante granular, sus aplicaciones han sido sólo en vías de poco tránsito. En este orden de ideas, el presente estudio consistió en agregar “MAPIA” a una MDC-19 junto con “GCR” (Grano de caucho reciclado) con el fin de evaluar las propiedades volumétricas en base a las normativas colombianas. Se seleccionó dos porcentajes de Mapia 4 y 6% y se procedió a realizar diseño de mezclas por el método Marshall, finalmente se obtuvo valores favorables en cuanto a la estabilidad y flujo, lo que podría significar su uso en vías con tráficos NT2 y NT3.

Sustainability reporting and financial performance: Evidence from Australia's electricity companies
Authors: Mamun Mehadi
Published: January 2022

This study, based on the stakeholder theory, explores the relationship between Australia’s electricity companies’ sustainability reporting practices and their financial performance. This paper uses the GRI G4 sector-specific guidelines to examine Australia’s electricity companies’ disclosure level on sustainability, return on assets to assess the companies’ performance, and descriptive statistics and multiple regression to test hypotheses. Relying on the secondary data collected from companies’ annual reports, websites, corporate social responsibility (CSR) reports, or standalone sustainability reports, the regression results show that the sustainability reports have a connection with the companies’ performance. Additional analysis also reveals that only economic and social performance disclosures of sustainability reporting significantly influence the companies’ performance. Though earlier studies on the relationship between sustainability reporting and financial performance have mostly been based on international data, this paper inspects the connection between the adoption of sustainability reporting and the financial performance of electricity companies within Australia that provide essential services to society and have a significant influence on sustainable development. Moreover, this research arbitrates prior inconsistent findings (Garg & Gupta, 2020; Bhattacharyya & Rahman, 2019; Sila & Cek, 2017) and adds to the sustainability reporting and firms’ performance literature

Published: January 2022

Objectives Endoscopic endonasal transsphenoidal adenomectomy (TSA) is
the most frequently performed skull base surgery and researchers have
recently focused on preserving nasal function. The transseptal approach
is a promising procedure owing to its less injury to nasal mucosa.
Therefore, we conducted this study to investigate whether the
transseptal approach could reduce nasal morbidities with comparable
neurosurgical outcomes. Study design Retrospective chart review. Setting
Single-institution tertiary care centre. Participants 25 patients of
transseptal approach from January 2019 to December 2020 and 25 patients
of transnasal approach from January 2017 to December 2018. Main outcome
measures Lund-Kennedy endoscopic scores, 22-item sinonasal outcome test
(SNOT-22) scores, TIB smell identification tests (TIBSIT®) scores, the
rate of gross total resection, endocrine control, and postoperative
complications were collected. Results The postoperative SNOT-22 (4.40
vs. 7.36, P =.005) and Lund-Kennedy endoscopic scores (2.72 vs, 5.08 at
2 weeks, 0.88 vs. 3.52 at 1 month, 0.48 vs. 2.12 at 3 months, 0.04 vs.
1.76 at 6 months, all adjusted P < .01) were significantly
lower in the transseptal group, while the TIBSIT scores were not
significantly different (41.6 vs. 42.4 preoperatively, P = .68; 41.6 vs.
40.2 postoperatively, P = .46). The rates of gross total resection,
recovery of hormonal abnormalities, and complications were not
significantly different. In multivariate analysis, the transseptal
approach remained an independent factor for lower SNOT-22 scores and
Lund-Kennedy endoscopic scores. Conclusion The transseptal approach
provides better recovery of nasal mucosa and intact olfactory function
without compromising neurosurgical outcomes.
Is a community state reachable, and why?
Authors: Herve Mathieu de Goër de , Thomas Colin , Cosme Maximilien , Warren Philip , Gaucherel Cédric
Published: January 2022

Deterministic models have difficulties to take into account
stochasticity during community assembly. As a tool to circumvent this
problem, we present a qualitative discrete-event model, where
consequences of interspecific interactions are described as rules. This
model provides a map of all possible future dynamics for a given system,
which allows to exhaustively describe the possible pathways during an
assembly process. Such a description does not rely on species traits
details and is insensitive to stochastic effects. This allows to show
that subsets of species are sometimes impossible to reach starting from
larger sets of species, and therefore to question the reachability of
community states during the system’s dynamics. Applying the model to an
experimental dataset studying the collapse of protist communities, we
obtain a very good theory-experiment agreement. We finally discuss what
the notion of reachability can bring to community assembly.
EVALUATION OF RIGHT VENTRICULAR PERFORMANCE IN PATIENTS WITH POSTOPERATIVE CONGENITAL HEART DISEASES USING DOPPLER TISSUE IMAGING AND CARDIOPULMONARY BYPASS INDICES

Published: January 2022

The RV is considered “the forgotten side of the heart”; however,
limited studies have focused on its evaluation . The RV helps manage
various cardiovascular diseases. Its function is a strong determinant of
the prognosis for patients with congenital heart defects, ischemic heart
disease, pulmonary arterial hypertension, congestive heart failure, and
cardiomyopathy. Therefore, its function should be assessed accurately.
Although cardiac magnetic resonance imaging remains the gold standard
for the noninvasive measurements of RV size and function, it is
time-consuming, expensive, and sometimes not feasible in everyday
clinical practice. Echocardiography is the first and the only method
used frequently for RV evaluation because of its availability and
cost-effectiveness. The complex anatomy of the RV and its trabeculated
myocardium that impedes clear endocardial border tracing, unfavorable
position within the thoracic cavity, and high dependence on the loading
conditions of traditional RV systolic function indices make the
echocardiographic analysis of the RV somewhat challenging. The RV
primarily helps pump blood coming from the systemic venous system to the
pulmonary trunk. The first parts to contract are the inlet and
trabeculated myocardium, and, after 25–50 ms, the conus contracts. The
RV functions as a high-volume, low-pressure pump; the contraction of
predominantly longitudinal fibers as well as afterload and preload
influence the RV’s performance. In addition, RV systolic synchrony,
atrioventricular synchrony, and ventricular interdependence. A previous
study has reported that 20%–40% of the RV volume outflow and systolic
pressure is caused by the contraction of the left ventricle (LV). RV
dyssynchrony potentially reduces the cardiac output or increases the
filling pressure. Thus, maintaining the sinus rhythm and
atrioventricular synchrony is crucial for the performance of the RV,
particularly in the case of chronic RV failure and acute RV infarction.
The current guidelines for cardiac chamber quantification suggest
sonographers to use multiple acoustic windows to precisely observe the
right heart from various perspectives. Because no single index of
contractility that perfectly describes RV performance exists, various
parameters need to be measured. In the clinical practice, the most
common and feasible indices that can be used to evaluate the RV systolic
function are Doppler tissue imaging, tricuspid annular plane systolic
excursion (TAPSE), derived tricuspid lateral annular systolic velocity
(S′ wave), and fractional area change (FAC).
Diversity and Composition of Soil Microorganisms between Abandoned and Selective-Farming Farmlands in an Antimony Mining Area
Authors: Du Yihuan , Duan Renyan , Zhang Yaqi , Yang Li , Lin Yuxiang , Yucai Luo
Published: January 2022

Background and Aims Land abandonment and selective farming are two
common management methods to restore the soil conditions of low
pollution farmland in mining areas. The soil microbial community plays
an important role in farmland soil restoration, however, few studies
have compared the composition and diversity of soil microorganisms
between the abandoned farmlands (AFS) and selective-farming farmlands
(FFS). Here, the effects of AFS and FFS on soil properties and microbial
diversity were evaluated in an antimony (Sb) mining area in southern
China. This study aimed to identify effective land management methods in
terms of positive or negative changes in soil environment and bacterial
diversity. Results Due to the influence of long-term fertilization, the
nutritional properties (e.g., available N, P, and K) of soil in FFS were
significantly improved and the microbial alpha diversity including Chao1
index, Simpson index, Shannon index, and Pielou-e index significantly
increased, compared to AFS. At the phylum level, FFS had higher relative
abundances of Chloroflexi, Acidobacteria, Gemmatimonadetes, and
Rokubacteria, and lower relative abundances of Firmicutes,
Actinobacteria, and Bacteroidetes. At the genus level, FFS had higher
relative abundances of Acidothermus, Haliangium, and Rokubacteriales,
and lower relative abundances of Bacillus, Rhodococcus, Sphingomonas,
and 67-14. Redundancy analysis indicated that soil heavy metal content
and soil fertility were closely correlated with the soil microbial
community. Altogether, selective farming of low pollution farmland in
the mining area can improve soil properties and soil microbial
diversity.

A rapidly convergent approximation scheme for nonlinear autonomous and non-autonomous wave-like equations
Authors: Das Prakash , Panja M.M.
Published: January 2022

In this work, an efficient approximation scheme has been proposed for getting
accurate approximate solution of nonlinear partial differential equations
with constant or variable coefficients satisfying initial conditions in a
series of exponential instead of an algebraic function of independent
variables. As a consequence: i) the convergence of the series found to be
faster than the same obtained by few other methods and ii) the exact
analytic solution can be obtained from the first few terms of the series of
the approximate solution, in cases the equation is integrable. The
convergence of the sum of the successive correction terms has been
established and an estimate of the error in the approximation has also been
presented. The efficiency of the present method has been illustrated through
some examples with a variety of nonlinear terms present in the equation.
Using an unmanned aerial vehicle (UAV) for lake management: ecological status, lake regime shift and stratification processes in a small Mediterranean karstic lake
Authors: Moreno Jose Luis , Ortega Jose Fernando , Moreno Miguel Ángel , Ballesteros Rocío
Published: January 2022

High-resolution remote sensing imagery by unmanned aerial vehicles (UAVs) has been used as a tool for the environmental management of natural resources. Monitoring programmes that evaluate the ecological status of water bodies according to the Water Framework Directive (WFD) involve significant costs and sampling efforts that can be reduced by using UAVs. UAV imagery was used to measure some metrics of the “macrophytes and phytobenthos” biological quality element (BQE), which is required to assess the ecological status of European lakes; e.g. the percentage cover of hydrophytes and helophytes. Eight UAV flights took place during an annual cycle (July 2016 to July 2017) in a small karstic lake located in southeast Spain. Limnolog¬ical surveys of physicochemical (temperature, conductivity, dissolved oxygen, pH) and biological (pigments) parameters were simultaneously performed to correctly interpret the UAV images. For each flight performance, an orthomosaic of georeferenced RGB images was obtained, and the different features of interest were monitored and quantified by an automated identification and classification system (the LAIC software). The UAV images allowed us to not only evaluate the lake’s ecological status by measuring macrophyte metrics, but to also detect relevant ecological events for environmental management. A gradual burial process of charophyte meadows by the proliferation of periphytic cyanobacterial was detected in an early state by UAV images. Stratification processes, such as hypolimnetic sulphur bacteria blooms or metalimnetic white colloidal layers, were also ob¬served by UAV imaging. We conclude that UAV imagery is a useful tool for environmental lake management.
In vitro AND in silico EVALUATION OF THYMOQUINONE AS POTENTIAL ANTICANCER AGENT IN HUMAN ACUTE MYELOID LEUKEMIA HL-60 CELLS
Authors: TEKİN KARACAER Neslihan
Published: January 2022

This study aims to explore the cytotoxic, apoptotic and autophagic effects of thymoquinone on human acute myeloid leukemia. The cytotoxic effects of thymoquinone were determined with 3-(4, 5-dimethylthiazol-2-yl)-2 and 5-diphenyltetrazolium bromide (MTT) tests. B-cell lymphoma 2 associated X protein (Bax), B-cell lymphoma 2 (Bcl-2), caspase 3, mammalian target of rapamycin (mTOR), phosphatidylinositol-3-kinase (PI3K), and protein kinase B (AKT) gene expression analyzes were studied with quantitative real-time polymerase chain reaction (qRT-PCR). AutoDock Tools 4.2 software was applied to research the potential binding of thymoquinone in the active sites of Bax, Bcl-2, caspase 3, mTOR, PI3K, and AKT proteins. Thymoquinone caused a cytotoxic effect on HL-60 cells (Human leukemia cell line) with a value of 16.35 µM. Bcl-2 expression was decreased in all concentrations applied compared to the control. A decrease in caspase 3 expression level was detected in the cells treated with 10 µM, 15 µM, and 25 µM thymoquinone compared to the control. Thymoquinone induced an important decrease in mTOR and PI3K expressions compared to the control at all doses, while AKT decreased at a dose of 15 µM. The docking outcomes showed that thymoquinone interacts with the active site amino acids of apoptotic and autophagic proteins via hydrophobic interactions and hydrogen bonding. The present findings suggest that thymoquinone can stimulate autophagy by prevention of PI3K/AKT/mTOR pathway in HL-60 cells and may become a new target for the therapy of acute myeloid leukemia.

Evaluation of knowledge and attitudes of physicians in Turkey about body donation processes
Authors: Kurtoğlu Olgunus Zeliha , Yeşil Kayabaşı Çisem
Published: January 2022

Objectives: Individuals who want to get information about body donation sometimes apply to physicians instead of Anatomy Departments in Turkey. The aim of the study was to evaluate the knowledge and attitudes of physicians who are frequently consulted by body donors. Methods: In this descriptive study, questionnaire form which consisted of three parts and 20 questions was prepared. In the first part, demographic informations; in the second part; the physicians’ answers to frequently asked body donation questions and physician responsibilities in the process; in the third part, the physicians’ request for information was questioned. The survey was conducted online. Results: Of the 238 physicians from 33 different provinces (aged between 25–68 years, 58.8% female, 41.2% male), 62.6% were specialist, 37.4% were non-specialized. 12.6% of them stated that at least one person applied to them for body donation. While only 52.5% of the physicians chose the Anatomy Departments to direct the donor, 35.3% chose the Organ Donation Units. 80.3% did not know that the body of an individual who did not fill out the donation form could be donated by their relatives and 29.4% did not know that body donation does not prevent organ donation. 90.8% of the physicians stated that they needed to be informed about the laws and procedures related to cadaver donation. Conclusion: The study reveals that physicians do not have enough information about body donation and they demand to be informed about it. The findings should be carefully evaluated as a factor that may adversely affect the decision of the body donor who cannot be properly guided by the physicians.

The key missions for the members of the RAB are to participate in three of five activities: (1) the PRS journal club on Facebook, (2) the PRS Grand Rounds (a multipronged and multitopic live lectures with question-and-answer series)2 via Facebook, (3) creation of PRS promoting videos on their own social media pages, (4) supporting PRS and PRS Global Open as a peer-reviewers, and (5) voting on the journal’s social media pages.

The search for a true leader to take on the role as the Founding Resident Ambassador for the Journal of Diagnostics and Treatment of Oral and Maxillofacial Pathology was an uneasy task. After an extensive search, we are honored to start a collaboration with an oral and maxillofacial surgery (OMS) resident from the state of Alabama in the United States of America. John M. Le, DDS, MD and his colleagues in the Department of Oral and Maxillofacial Surgery at the University of Alabama at Birmingham have made a serious impact on global oral and maxillofacial surgery specialty. Moreover, their article contribution to our journal in 2020 made a huge influence by attracting an international community of readers to our journal, making us enormously proud. The masterpiece was dedicated to the use of zygomatic implants for restoration of complex nasal defects. Thereby, the current academic achievements and research activities of Dr. Le serves as a model for other OMS residents in training. In general, his clinical interests include, but is not limited to head, neck and oral oncology and reconstructive surgery.

We aimed to investigate the somatic distress and psychological symptoms levels of cancer patients, and analyze the influencing factors on somatic distress during COVID-19 pandemic. This cross-sectional study included 216 eligible cancer patients. The Patient Health Questionnaire-15, Post-Traumatic Stress Disorder (PTSD) Checklist for DSM-5, The Depression, Anxiety and Stress Scale-21, the Brief Resilience Scale, the Stressful Life Events List due to Pandemic were administered to the participants. The moderate to severe somatic distress rate was % 38 and probable PTSD rate was 20.4%. Depression, anxiety and stress symptoms were 36.1%, 49.1% and 45.4%, respectively, from mild to extremely severe. There were substantial association between somatic symptoms severity and high PTSD, anxiety, depression, and stress symptoms levels. Low education, high anxiety levels, high experience stressful life events, and low psychological resilience predicted high somatic distress. This study demonstrates the high risk of somatic distress, PTSD, depression, anxiety and stress in patients with cancer during the pandemic. In addition, somatic distress may indicate high levels of psychological symptoms, high experience stressful life events, and low psychological resilience. It underscores the need to assess psychological status during the pandemic, especially those with high level somatic symptoms.

Islands, especially smaller ones, are characterized by discontinuity of space and are considered as some of the least accessible areas. In this paper, we seek to shed light on the accessibility problems that islands face from the point of view of island residents. This shift in emphasis considers additional aspects to accessibility that include the availability of connections to access services required to cover the needs of island residents and the different destinations where these may be available, and the time that one may have to spend to get to these destinations in order to use these services. An alternative measure of accessibility is proposed, based on the time required to travel; this is then applied to three different Greek islands in the Aegean Sea. The accessibility of the residents of these islands to selected services is compared with that of settlements in continental Greece of similar population and distance to the capital Athens. The findings clearly demonstrate the adversities that island residents have to face, especially for smaller islands, where accessing selected services may require as many as four destinations, with virtual distances 4 to 6 times longer than ‘real distances’.

Cabai merupakan komoditas hortikultura yang memiliki nilai ekonomis tinggi, namun dalam budidayanya terdapat beberapa kendala dari hama dan penyakit. Penyakit yang sering ditemui yaitu penyakit kuning dan penyakit keriting daun yang disebabkan virus. Virus yang menyerang cabai biasanya ditularkan serangga vektor. Penelitian ini bertujuan untuk mengetahui respon serangga vektor yang tertarik pada masing-masing perlakuan warna mulsa yang akan berdampak pada insidensi dan intensitas penyakit. Percobaan dilakukan menggunakan tujuh warna mulsa plastik dan diulang sebanyak tiga kali, dan menggunakan rancangan acak kelompok (RAK). Variabel yang diamati meliputi insidensi dan intensitas penyakit kuning dan penyakit keriting daun, serta bobot dan jumlah buah cabai. Hasil percobaan menunjukkan bahwa penggunaan mulsa warna tidak berpengaruh pada insidensi penyakit virus kuning maupun insidensi penyakit virus keriting serta pada bobot buah dan jumlah buah cabai. Namun warna mulsa biru, kuning, merah, dan putih menghasilkan intensitas penyakit virus kuning maupun virus keriting yang lebih tinggi dibandingkan dengan mulsa warna hitam, coklat, dan hijau.
