Ecotourism in Russian Karelia: Emergence, development, opportunities
Authors: Osipov Alexander
Published: August 2019

This review article examines the development of ecotourism in national parks in the Republic of Karelia over the last 30 years. In Russia, the term “ecotourism” has appeared in newspapers and scholarly articles since the 1990s and its popularity is still increasing. The authorities in the Republic of Karelia have argued that tourism and especially ecotourism have the potential to become a major sector of the Republic’s economy. This article focuses on the meaning of this term internationally, and especially in the context of Russia and Karelia, and considers this definition through the lens of conventional historiography. The key issue of this research is the triangular relationship between ecotourists, local communities and wildlife conservation areas or national parks, where ecotourism functions as a major tool, connecting all these points. This paper applies comparative historical research methods as part of a qualitative approach, analysing a variety of primary sources including archive materials, interviews and forum discussions. The article concludes that the slow growth of ecotourism, despite the attempts of regional authorities and the assistance of the European Union, is due to several reasons including remote locations, poor infrastructure and the lack of symbolic meaning for national parks.

Exercise is a stress factor, acting on the body, leads to changes in the hemostatic system and in particular - the fibrinolytic activity. The aim of the study was to compare the genetic characteristics of the athletes, the natives of the European north, with phenotypic markers of hemostasis. Method of sampling - continuous. The study involved athletes engaged in different sports, with sports category of the first and above, followed by the Arkhangelsk center of sports medicine. Using PCR and ELISA methods indicators of fibrinolysis and six polymorphisms of genes of the hemostatic system proteins have been evaluated. Research of hemostasiological status and genetic polymorphisms of some hemostatic system proteins in the group of athletes have revealed susceptibility to decreased activity of fibrinolysis and increase blood coagulation potential. The reason for the differences due to the higher, compared with the European, incidence of adverse associated trait in relation to polymorphisms of fibrinogen - 40.5 % in the athletes (CI: 30.3 - 51.1 %) against 20 % in the European population; platelet fibrinogen receptor - 25% (CI: 16.3 - 34.8 %) against 13 % in the European population, plasminogen activator inhibitor - 77.4 % in the athletes (CI: 67.9 - 85.7 %) against 53-61 % in the European population. A direct correlation between the presence of adverse gene polymorphism of plasminogen activator inhibitor-1 and this factor was revealed, which indicates the phenotypic expression of genetically determined depression of fibrinolysis.

Due to the intensive development of coastal zones of upper reaches of the Kuban River basin - the main waterway of the North Caucasian and the Southern Federal districts, pollution of surface water with chemical elements and connections takes place. It creates conditions for background development of various diseases, the water run-off decreases at the head of the main basin formation. Considering exclusive importance of health resort, recreational and climate mountain orographical system of Karachay-Cherkessia which is Kuban River "cradle" carrying out geoenvironmental and balneological monitoring is of main priority. This paper investigates the role of the mountain rivers from the point of view of water resources in medico-ecological comfort of a tourist and technogenic complex: Teberda - Dombai. Possibilities of qualitative assesment of these resources, as well as some related problems are discussed in this paper. Recommendations for effective management of a catchment basin while solving ecological-and-health problems of the mountain resort are provided.

Authors: Dernovoy B F
Published: August 2019

Cardio-hemodynamics and systemic hemocirculation of a person before and after cold test influence in contrast year seasons was investigated to study the influence of environmental temperature on various parts of the cardiovascular system. Heart rate, speed and time of transaortic blood flow in the aortic root were measured by echocardiography. Systolic and diastolic blood pressure was measured by tonometer on the stages of cardio-hemodynamics study. It was established that the person in clinostatic body position and in a state of relative rest had lower diastolic blood pressure, speed transaortic blood flow and performance of the heart in December than in June. The study showed that the body's response to cold test influence in the summer was characterized by decreased systolic blood pressure, increased heart rate and short-term reduction of cardio-hemodynamics. In winter, the period of low air temperature local freezing caused at first increase of systolic blood pressure, and in succeeding period decrease of systolic blood pressure relative to baseline values. Wherein, change in cardio-hemodynamics and chronotropic function of the heart was not found. The results showed reduced peripheral vascular tone, less venous return to the heart with a decrease of cardio-hemodynamics and myocardial performance of a person in the cold season. The reaction of the cardiovascular system to the local freeznig was more obvious in the summer and was accompanied by a positive chronotropic effect, decreased intracardiac and systemic hemodynamics during the period of circulatory homeostasis of the body after the test.

Published: August 2019

The main approaches of psychophysiological investigations of horme regulation and their development from studying the connection of cognitive processes with the prevailing rhythms of the brain electric activity and the neurovegetative system manifestations to revealing the phase changes in the brain activity foci have been analyzed in the literature review. The data on the sex differences of psychophysiological activity provision have been summarized and the possibilities of its improvement through various methods of biological feedback have been shown. Special attention has been paid to the fact that while studying horme in the majority of cases its organization is estimated by the efficiency parameter, while at present regulation is regarded as the manifestation and the dynamics of various physiological processes. In this connection, it has been suggested: while studying the horme regulation consider it as a content independent, different in complexity and heterogeneity, prolonged system-information process of human activity organization. This process is supposed to reflect a certain condition, have its own individual characteristics and properties provided by neurophysiological mechanisms, the initial level of energy resources and connected with individual features of information management and energy expenditure. On the basis of the data on trainability and on using the biological feedback a conclusion has been drawn that the combined estimation of the efficiency of activity regulation in the conditions of absence or presence of an external feedback makes it possible to adequately estimate the adaptive abilities as well as to control, to predict and if necessary to correct the functional condition of the human body.

Published: August 2019

Nozologically formed borderline mental disorder (BMD) in combatants have a lower prevalence of mental disorders unlike a painful level. Blurred diagnostic criteria do not allow to attribute to the category of BMD the short-term outage of disturbance of mental adaptation - transient affective and behavioral reactions (TABR). In order to develop the expectancy model of TABR formation an analysis of personality characteristics of 649 combatants of the Interior Ministry have been carried out. Intermittent TABR in anamnesis revealed in 311 persons, such states and other violations of mental adaptation was not recorded in 338. Four years later, after the trip to zones with special service conditions, according to the I. Kotenev's method and Bass-Dark's test combatants revealed signs of maladjustment and high levels of physical aggression. Based on the data the TABR model has been designed using logistic regression and method of forced variables input. It was found that the risk of TABR formation increases with a decrease in the indicator "the invasion of the symptoms" scale and by increasing the parameters in the scale of "hyperactivity symptoms," "distress and maladjustment," "signs of post traumatic stress disorder" "physical aggression" and "verbal aggression". This shows that TABR more often appear in combatants with increased excitability in everyday life and a high level of physical aggression, while the symptoms of re-experiencing the traumatic event are not the triggering factor of TABR formation. This technique was proposed to use in medical and psychological support of personnel to prevent formation of TABR in combatants.
CHARACTERISTIC OF BRAIN ELECTROBIOLOGICAL ACTIVITY IN ELDERLY WOMEN WITH DIFFERENT LEVEL OF COGNITIVE DISORDERS
Authors: Deryabina I N
Published: August 2019

The paper shows the study results of a brain electrobiological activity in elderly women with various level of cognitive impairment. Importance of early diagnostic of cognitive disorders and applicability of methods of functional brain imaging in revealing disorders in higher cortical functions are shown in the paper. To assess cognitive functions we applied express-method of evaluating of cognitive functions during normal aging. According to the test results three groups were formed: 1 - women without cognitive disorders, 2 -with mild cognitive impairment, and 3 - with moderate cognitive impairment. The EEG was registered for all participants by means of 128-channel system GES-300. Absolute spectral power for all bands was calculated. According to the spectral analysis it has been revealed that higher power of the slow-wave rhythms is characteristic of groups with disorders of cognitive functions. Prevalence of a delta rhythm in the general EEG has been also stated. These changes are perhaps caused by dysfunction of the activating cholinergic systems and cortical structures, and also both dyscirculatory and structural changes of brain matter.
Writers as Leaders of Nation: Typological Convergence of I. Franko and P. Kulish
Authors: Nakhlik Yevhen
Published: August 2019

The article draws a parallel between P. Kulish’s and I. Franko’s disposition to the age-related ideological autorevision. It is argued that, experiencing evolution of the worldview and creative work, revising his own early radical social impulses caused by the ‘national radical stage’ (Franko’s deﬁnition) of liberation movement in Halychyna, mature Franko in 1896 – 1907 got closer to the views of P. Kulish, especially those of the late period of his life (1874 – 1897). Like the latter, Franko defended the right to worldview evolution and changing views. These typological coincidences consisted also in the movement from the center-left forces to the right-centered ones; the transition to the primacy of the national idea over the social one; the drastic national self-criticism and simultaneous emphasis on the nation-building and state-building; gradual reorientation from the idea of social revolutionary development of society to evolutionary progress and moderate “means and ways of acting and speaking” (as Franko called it); the warnings against admiring communist illusion, against ochlocracy; and, ﬁnally, in the focus on the leading role of the nationally conscious Ukrainian intellectuals in the liberation struggle. Ideological and formal parallels between Franko and Kulish were revealed not only in the letters and journalism, but also in Franko’s practice of grounding his works on the materials of the national, biblical and Christian history and mythology (i. e. literary historicism and mythologism, focused on the present, the future and the author’s personality; symbolic autobiography). From this point of view it is worth to compare:  “Pisnia Budushchyny” (“Song of Future”) – “Try Braty” (“Three Brothers”); “Pokhoron” (“Funeral”), “Ivan Vyshenskyi” – “Velyki Provody” (“Great Farewell Procession”), “Marusia Bohuslavka”, “Dramovana Trylohiia” (“Drama-like Trilogy”); “Moisei” (“Moses”) – “Mahomet i Khadyza” (“Muhammad and Hadiza”), “Duma-Perestoroha, Velmy na Potomni Chasy Potribna” (“Warning Reﬂ ections that will be Needed in Future”); “Strashnyi Sud” (“The Last Judgement”) – “Kulish u Pekli” (“Kulish in Hell”); “Slavianska Oda” (“Slavic Ode”) – “Tsarski Slova” (“Royal Words”).
Censor History of Kulish’s Novel “The Black Council”: Introductional Remarks
Authors: Fedoruk Oles
Published: August 2019

A censor history is one of the most important issues in the textual study of Kulish’s novel “The Black Council”. However, this problem has never been considered before by the Ukrainian scholars, and even more general issue, i.e. “Kulish and the Censorship”, was not involved much into the ﬁeld of research. This paper gives an introduction to this topic shedding some light on the censor history of “The Black Council”.Relations between Kulish and the tsarist censorship in different times were ambiguous which was caused by several reasons. The ﬁrst one was individual approach of the censors to his works which might be connected, in particular, with the trial of Saints Cyril and Methodius Brotherhood (1847). Other reason was general persecution of the Ukrainian literature, especially after the Ems Ukase (1876). In order to circumvent censorship Kulish published his works also abroad. Before Kulish was arrested he wrote his works without paying particular attention to the censorship.

The ﬁrst writer’s concerns about possible restrictions that might be imposed on his works by the censorship arose with the novel “The Black Council”. Kulish’s arrest radically changed circumstances of his life and creative activity. Until 1856 he had to submit his works to prior censorship consideration and used pseudonym Nikolai M. (the name of his friend Nikolai Makarov) to avoid these restrictions. The Third Department of His Imperial Majesty’s Personal Chancellery allowed Kulish to publish his works on the base of the general censor regulations only in April 1856. In a short time Kulish sent the manuscript of “The Black Council” to the censorship committee.
Panteleimon Kulish as “the First Truly National Ukrainian Writer”
Authors: L Ivashkiv Vasyl
Published: August 2019

The essay develops I. Franko’s statement about P. Kulish as the ﬁrst truly national Ukrainian writer who aimed at working totally for the sake of his people’s needs. The author underlines that such a desire was Kulish’s natural urge, as the mentioned goal arose for him back in the ﬁrst half of the 1840s. In particular, he planned to publish everything that vividly reﬂ ected the life of the Ukrainians throughout centuries.

In the early period of his activity Kulish worked mainly as a folklorist. He recorded and studied Ukrainian folklore in its natural environment. This work resulted in a unique ethnological edition “The Notes on Southern Rus” as well as his widely known ‘farmstead philosophy’. Kulish’s writing activity evolved from his desire to provide a complex picture of his people’s centuries-long heroic history in the poetic epopee “Ukraine” to creating his ﬁ rst Ukrainian historical novel “The Commoners’ Council.

A Chronicle of 1863”. The pan-Ukrainian level of “The Notes on Southern Rus” and “The Commoners’ Council” was supported with Kulish’s own phonetic spelling system, i.e. ‘kulishivka’ which laid the foundation of the modern orthography. Kulish’s writing and ethnological activity was also based on his urge to raise the contemporary Ukrainian language to the literary level. With such a purpose he published the almanac “Khata” (“The House”) and did a lot for the full-scale functioning of the ﬁrst Ukrainian literary magazine “Osnova” (“The Foundation”). Kulish’s translation activity became another important part of his work as the ﬁrst national writer. His translations of the Bible, works by W. Shakespeare, G. G. Byron, J. W. Goethe, F. Schiller and other outstanding classics of the world culture were signiﬁ cant for all Ukraine.
Description of Νecropolis in “The Commoners’ Council”: Issue of Sources
Authors: Nazarenko Mykhailo
Published: August 2019

Both in the magazine publication of 1846 (“Kyivan Pilgrims of the 17th Century”) and in the Russian 1857 version of “The Commoners’ Council” Panteleimon Kulish claimed that the epitaphs from the Assumption Cathedral of the Kyiv-Pechersk Lavra were taken from Afanasii Kalnofoyskyi’s “Teraturgema” (1638) and translated into Russian. However, the comparison of the texts shows that the translations were actually taken from Mykhailo Maksymovych’s paper “On Tombstones in Pechersk Monastery” (1840). Other quotations with references to the “Teraturgema” were borrowed from the work of metropolitan bishop Yevhenii (Bolkhovitinov) “Description of Kyiv Perchersk Lavra” (1826).

 The Kyivan episodes of “The Commoners’ Council” were mainly based on two Maksymovych’s papers from “Kiievlianin” (“The Kyivan”) almanac (1840), the aforementioned one and “Overview of Old Kyiv”. Kulish did not mention any of these sources in the novel’s footnotes. This fact should be considered in the context of the system of references that the writer built in “The Commoners’ Council”. Unlike many authors who worked in Walter Scott tradition, Kulish didn’t use footnotes in “The Commoners’ Council” in order to acknowledge and justify certain anachronisms and time distortions.

The writer referred to the testimonies of the witnesses of historical events, even after he had received an information from the people of the 19th century (Shevchenko, for instance), to the folkloric texts, and his own observations. The works of historians were important for him as far as they offered published collections of the authentic documents, but not as the sources of concepts. No intermediaries could stand between the historian novelist and the depicted age.
‘Eastern Poems’ by P. Kulish at Crossroads of Asian Mysticism and European Romanticism
Authors: Lanovyk Mariana , Lanovyk Zoriana
Published: August 2019

The paper considers the main Panteleimon Kulish’s epic poems “Marusia Bohuslavka”, “Baida, Prince Vyshnevetskyi”, “Muhammad and Hadiza” with the focus on their oriental background. The idea of the eastern orientation of P. Kulish originates from the works of V. Shchurat, V. Ivashkiv and others. The main attention is drawn to the fact that Kulish was considerably acquainted with eastern cultures and religious systems (especially those of Near East and Middle East which he had to know as a translator of Bible) and often used eastern concepts in his philosophic and literary works. The researcher traces the inﬂuence of different factors in Kulish’s ‘Eastern poems’ at the levels of ideology and imagery. The analysis reveals that the main sources of the author’s creative ideas were the eastern religious mystical systems (such as Islam, Suﬁ sm) as well as European Romantic works, in particular those by Lord Byron and P. B. Shelley, that were created under the same inﬂuence of the eastern philosophic doctrines and philosophy of Spinoza. This content was most vividly embodied in Kulish’s ‘cordocentric’ doctrine contrasting with ‘ratiocentric’ European philosophies. The emphasis on the concept of the heart and emotional sphere is most eloquent and obvious in the image of Woman that is interpreted as the eastern category of eternal femininity. The eastern focus is also noticeable at the thematic level (the concepts of Truth, Love, and Eternity). The main poetical peculiarities of the analyzed works are found in the mystical thinking and belief in the sacred power of the Word. Thus the language of the poems is very allegoric, enigmatic, and mysterious; it rather veils the main meaning than reveals it. So it results in double meaning or multiplicity of interpretations and demands reading the poems with a search for a certain code or cipher for decoding the author’s imagery and parabolic content. That is why the poems leave the impression of paradoxical thinking and remain difﬁcult for understanding which relate them to the works by Lord Byron and P. B. Shelley (“Revolt of Islam”). Probably this combination of Asian mysticism and European philosophies was the main reason why some critics accused Kulish of being ‘non-synthetic’ personality (S. Yefremov). But oriental focus reveals the new way for understanding and interpreting the poems by Kulish, as well as his philosophic doctrine and personal position in life.
Coloristic Expressive Tools in Prose by Volodymyr Drozd
Authors: Brayko Oleksandr
Published: August 2019

The paper deals with coloristic means in the works by the well-known Ukrainian writer-Sixtier. It focuses on the functions of colors and color effects in the text, their analogues in painting, and the role of the colors in showing semantic and mood accents or expressing some implicated meanings. The researcher traces accordance of the literary means with expressive resources of painting art as they are recorded in the theory of art.

Throughout all the periods of the writer’s creative work the prose by V. Drozd shows the author’s attention to the plastic wealth of the outside world and its coloristic potential. The search for the graphic forms of a psychological analysis, as well as the mood dominant, the background of event, the expressive color markers of semantic accents or meaningful image components of exposition, and, after all, the very painting-like modeling of the landscape or interior, stimulated new graphic experiments that renewed and deepened aesthetic impact of a literary work on a reader, due to the culture of visual perception and constructive imagination.

The ﬁrst attempts of verbal design and color rendering in V. Drozd’s works still testify to his literary apprenticeship showing excessively decorative nature, unambiguity of semantic associations, bright hues and chromatic saturation that looks rather as adopted from pictures and not taken from nature. Such artistic approach to the theme generates enormous, and at the same time ideologically typical, pathos associated with aesthetics of socialistic realism and therefore with the teaching function of art.

The development of coloristic culture in the works of the prose writer is rooted in his attention to the rich range of hues, their emotional and expressive potential, and also in the author’s desire to show a psychological action in a more plastic and suggestive way. In order to reproduce the coloristic variety of sensory experience and underline important semantic implications the writer skillfully works on the parameters of achromatic light environment which becomes symbolized or transformed in a fantastic and hyperbolic way due to the expressive function of light markers.

The light and color contrasts or combinations of hues may underline some essential semantic aspects of the verbal picture components within the reproduction of a landscape. The analysis of ﬁgurative and modeling means proves the artistic functionality of the verbal analogues of painting in V. Drozd’s prose, and its consistency with the aesthetic dominants of the Sixtiers.

Authors: Qian H. , Kudashev S. , Plotnikov V.
Published: August 2019

We conducted two sets of experiments, one is under steady-state conditions and the other under pulsating conditions. We focused on measuring the heat transfer characteristics of plate heat exchangers under different pulsation conditions. In the experiment, we control the mass flow of the hot fluid to circulate at a rate of 0.722 kg/s. The mass flow rate of the cold fluid is 0.05-0.18 kg/s, and the pulsation frequency is 0.45-2.23 Hz. We measured different mass flows at different pulsation frequency. The data analysis shows that when the pulsation frequency is 1.78 Hz, the heat transfer coefficient reaches a maximum of 4415.73 w/(m2·k), and the corresponding cold fluid mass flow rate is 0.155 kg/s, and compared with the heat transfer characteristics of the plate heat exchanger under steady flow, it is found that the average increase in the heat transfer coefficient during the transition to the pulsating mode was 20%.

Authors: Shvaiba D.
Published: August 2019

In recent years, the financial and economic recovery increasingly rests on the problems of development of the transport network and energy. The measures are taken in recent years, including the reform of monopolies, have not led to a significant increase in investment in these segments of the economy. To some extent, this is due to the lack of institutional criteria to ensure the openness of their work, as well as control over the effective expenditure of funds. In order to resolve these tasks, the Government of the Republic of Belarus will implement measures aimed at the subsequent implementation of institutional reforms and stimulating the pace of financial and economic recovery. We need urgent measures aimed at improving the institutional system, including the creation of accurate and clear ‘rules of the game’ for all subjects, ensuring an increase in the confidence of all subjects of financial, economic and political activity in the Belarusian society. The previously mentioned instruments of the mechanism of ensuring the socio-economic security of Belarus form a strong base for the continuation of sustainable development for the long term. In addition, in order to stimulate financial and economic growth, it is necessary to implement tax policy, which is obliged to promote the increase of competitiveness and the rise of business activity of economic entities, as well as to guarantee the reduction of the tax burden for business, including reduction of the value added tax rate in the medium term, simplification of procedures for calculation and payment of taxes and streamlining of tax audits and reporting.

Impacts of Tamarix (L.) Litter and Mycorrhizal Amendments on Baccharis salicifolia (Ruiz & Pav.) Pers. Competitiveness and Mycorrhizal Colonization
Authors: Murray Leeland , Schutte Brian J. , Ganguli Amy C. , Lehnhoff Erik A.
Published: August 2019

Tamarix spp. are ecological threats in the Southwest U.S.A. because they displace native vegetation, increase soil salinity, and negatively affect soil microbial communities. After Tamarix L. removal, legacy effects often necessitate restoration to improve ecosystem services of Tamarix-impacted communities. Commercial mycorrhizae fungal inoculation has been recommended to improve restoration success, although inoculation treatments are rarely tested on lesser-known facultative riparian species. Our study asked two questions: (1) Can a commercial mycorrhizal fungal inoculant increase native Baccharis salicifolia (Ruiz & Pav.) Pers. (mule-fat) performance against Tamarix chinensis Lour. (i.e., tamarisk) and is this influenced by tamarisk leaf litter? (2) Is mycorrhizal colonization of mule-fat roots influenced by tamarisk stem density and leaf litter? A greenhouse experiment was performed with mule-fat cuttings in soil collected from a tamarisk monoculture. Treatments were factorial combinations of tamarisk stem densities (0, 1, 2, 3, 4 stems pot−1) with or without mycorrhizal inoculation and tamarisk litter. There were five replications and two greenhouse runs. The total biomass of both species was determined and mule-fat arbuscular mycorrhizal colonization rates were determined via the magnified intersection method. Increasing tamarisk biomass negatively affected mule-fat biomass, but there were interactions with tamarisk biomass, litter and mycorrhizal inoculation, with litter and inoculation increasing mule-fat growth at high tamarisk biomass. Arbuscular mycorrhizal colonization was high in all treatments, yet at higher tamarisk stem densities, inoculation and litter improved colonization. Interestingly, litter did not negatively impact mule-fat as predicted. Moreover, litter and mycorrhizal inoculum interacted with tamarisk to improve mule-fat growth at higher tamarisk biomass, suggesting an opportunity to improve restoration success when in competition with tamarisk.

Papillary thyroid carcinoma (PTC) variants exhibit different prognosis, but critical characteristics of PTC variants that contribute to differences in pathogenesis are not well-known. This study aims to characterize dysregulated immune-associated and cancer-associated genes in three PTC subtypes to explore how the interplay between cancer and immune processes causes differential prognosis. RNA-sequencing data from The Cancer Genome Atlas (TCGA) were used to identify dysregulated genes in each variant. The dysregulation profiles of the subtypes were compared using functional pathways clustering and correlations to relevant clinical variables, genomic alterations, and microRNA regulation. We discovered that the dysregulation profiles of classical PTC (CPTC) and the tall cell variant (TCPTC) are similar and are distinct from that of the follicular variant (FVPTC). However, unique cancer or immune-associated genes are associated with clinical variables for each subtype. Cancer-related genes MUC1, FN1, and S100-family members were the most clinically relevant in CPTC, while APLN and IL16, both immune-related, were clinically relevant in FVPTC. RAET-family members, also immune-related, were clinically relevant in TCPTC. Collectively, our data suggest that dysregulation of both cancer and immune associated genes defines the gene expression landscapes of PTC variants, but different cancer or immune related genes may drive the phenotype of each variant.
New Method of Prime Factorisation-Based Attacks on RSA Authentication in IoT
Authors: Venkatraman Sitalakshmi , Overmars Anthony
Published: August 2019

The potential benefits of the Internet of Things (IoT) are hampered by malicious interventions of attackers when the fundamental security requirements such as authentication and authorization are not sufficiently met and existing measures are unable to protect the IoT environment from data breaches. With the spectrum of IoT application domains increasing to include mobile health, smart homes and smart cities in everyday life, the consequences of an attack in the IoT network connecting billions of devices will become critical. Due to the challenges in applying existing cryptographic standards to resource constrained IoT devices, new security solutions being proposed come with a tradeoff between security and performance. While much research has focused on developing lightweight cryptographic solutions that predominantly adopt RSA (Rivest–Shamir–Adleman) authentication methods, there is a need to identify the limitations in the usage of such measures. This research paper discusses the importance of a better understanding of RSA-based lightweight cryptography and the associated vulnerabilities of the cryptographic keys that are generated using semi-primes. In this paper, we employ mathematical operations on the sum of four squares to obtain one of the prime factors of a semi-prime that could lead to the attack of the RSA keys. We consider the even sum of squares and show how a modified binary greatest common divisor (GCD) can be used to quickly recover one of the factors of a semi-prime. The method presented in this paper only uses binary arithmetic shifts that are more suitable for the resource-constrained IoT landscape. This is a further improvement on previous work based on Euler’s method which is demonstrated using an illustration that allows for the faster testing of multiple sums of squares solutions more quickly.

Syngas (mixture of CO, H2 and CO2) fermentation suffers from mass transfer limitation due to low solubility of CO and H2 in the liquid medium. Therefore, it is critical to characterize the mass transfer in syngas fermentation reactors to guide in delivery of syngas to the microorganisms. The objective of this study is to measure and predict the overall volumetric mass transfer coefficient, kLa for O2 at various operating conditions in a 7-L sparged and non-sparged continuous stirred-tank reactor (CSTR). Measurements indicated that the kLa for O2 increased with an increase in air flow rate and agitation speed. However, kLa for O2 decreased with the increase in the headspace pressure. The highest kLa for O2 with air sparged in the CSTR was 116 h−1 at 600 sccm, 900 rpm, 101 kPa, and 3 L working volume. Backmixing of the headspace N2 in the sparged CSTR reduced the observed kLa. The mass transfer model predicted the kLa for O2 within 10% of the experimental values. The model was extended to predict the kLa for syngas components CO, CO2 and H2, which will guide in selecting operating conditions that minimize power input to the bioreactor and maximize the syngas conversion efficiency.

The dissipation of three field-applied pesticides (chlorothalonil, chlorpyrifos, and malathion), on cultivated prickly pear (Opuntia ficus-indica (L.) Mill.) pads was studied. The extraction of pesticides was carried out using the European quick, easy, cheap, effective, rugged, and safe (QuEChERS) extraction technique and detection was carried out using tandem liquid chromatography with mass spectrometry. At harvest, 15 days after application, pesticide dissipation was below the level of detectability. Dissipation curves for prickly pear pads fit to a first-order kinetic equation. Two initial concentration levels were used for each pesticide. The approximate dissipation time for all pesticides studied was similar (10 days) and the half-life time was around six days. Final concentrations for the three pesticides were below the reference maximum residue level (MRL) (0.01 mg/kg), which suggests that these products can be applied safely in the commercial production of prickly pear pads at the established concentrations.

With the rapid development of China’s economy, the environmental problems are becoming increasingly prominent, especially the PM2.5 (particulate matter with diameter smaller than 2.5 μm) concentrations that have exerted adverse influences on human health. Considering the fact that PM2.5 concentrations are mainly caused by anthropogenic activities, this paper selected economic growth, economic structure, urbanization, and the number of civil vehicles as the primary factors and then explored the nexus between those variables and PM2.5 concentrations by employing a panel data model for 31 Chinese provinces. The estimated model showed that: (1) the coefficients of the variables for provinces located in North, Central, and East China were larger than that of other provinces; (2) GDP per capita made the largest contribution to PM2.5 concentrations, while the number of civil vehicles made the least contribution; and (3) the higher the development level of a factor, the greater the contribution it makes to PM2.5 concentrations. It was also found that a bi-directional Granger causal nexus exists between PM2.5 concentrations and economic progress as well as between PM2.5 concentrations and the urbanization process for all provinces. Policy recommendations were finally obtained through empirical discussions, which include that provincial governments should adjust the economic and industrial development patterns, restrict immigration to intensive urban areas, decrease the successful proportion of vehicle licenses, and promote electric vehicles as a substitute to petrol vehicles.

To mitigate the potential environmental risks caused by nitrogen compounds from industrial wastewater, residual ammonia after conventional wastewater treatment should be further eliminated. In this work, an electrochemical oxidation process for converting ammonia to nitrogen in actual dyeing wastewater was investigated. The effects of the main operating parameters, including initial pH value, applied current density, NaCl concentration, and flow, were investigated on ammonia removal and products distribution. Experimental results indicated that, under optimal conditions of an initial pH value of 8.3, applied current density of 20 mA cm−2, NaCl concentration of 1.0 g L−1, and flow of 300 mL min−1, the ammonia could be completely removed with N2 selectivity of 88.3% in 60 min electrolysis. A kinetics investigation using a pseudo-first-order model provided a precise description of ammonia removal during the electro-oxidation process. Experimental functions for describing the relationships between kinetic constants of ammonia removal and main operating parameters were also discussed. Additionally, the mechanisms and economic evaluation of ammonia oxidation were conducted. All these results clearly proved that this electro-oxidation process could efficiently remove ammonia and achieve high N2 selectivity.
