Normative regulation of ﬁre safety of infrastructural objects of hydrogen energetics
Authors: Shebeko Yu. N.
Published: July 2021

Introduction. Now many countries produce measures for a transfer of their economics to an application of a hydrogen energetics. Because of a high ﬁre hazard of hydrogen a ﬁre safety provision of infrastructural objects of the hydrogen energetics is a very important task. The infrastructural objects of the hydrogen energetics are the facilities aimed on a production and storage of hydrogen, transportation of gaseous (GH2) and liquid (LH2) hydrogen, an application of hydrogen for an energy generation, car refueling stations etc. Scientiﬁc basis for a creation of the ﬁre safety normative documents was laid in studies of Russian and foreign investigators.

Russian normative documents. Russian normative documents in the area considered are analyzed in this work. A draft of the Technical Regulation on a safety of the facilities aimed on production, storage, transportation and application of hydrogen is the most important among them. This document contains a lot of speciﬁc requirements which should be used independently of a type of the hydrogen facility. Therefore this document can be considered as extremely “rigid” for a practical applications. A set of rules SP 162.1330610.2014 is aimed on the regulation of the safety requirements for the facilities using liquid hydrogen. The document PB 03-598-03 considers the safety requirements for a production of hydrogen by an electrolysis of water. A conclusion was made that Russian normative basis is not sufﬁcient for a development of the hydrogen energetics.

Standard NFPA 2. The standard NFPA 2 can be considered as a most important normative document containing the safety requirements for the facilities for production, storage, transportation and application of hydrogen in a gaseous and a liquid phase. This standard contains both general and speciﬁc requirements for the infrastructural objects such as car refueling stations, storages of hydrogen in the gaseous and the liquid phase and also using metal hydrides, hydrogen production facilities, energy generation objects using hydrogen, technological equipment containing hydrogen, laboratory facilities, car parks for the cars using hydrogen as a fuel etc.

Conclusions. It was found that there is no comprehensive set of the normative documents regulating ﬁre safety of infrastructural objects of hydrogen energetics. The series of the Russian normative documents in this area which should be created was proposed. A conclusion was made that the requirements of NFPA 2 can be used at a creation of the Russian normative basis of the hydrogen energetics.
Efﬁciency of ﬁre suppression systems using dry powder sprays to extinguish ﬁres amid non-steady heat exchange processes and heterogeneous inhibition of active ﬂame centres by powder particles
Authors: Kitsak A. I.
Published: July 2021

Introduction. Presently, there are several problems in the ﬁeld of dry powder ﬁre suppression that require the indepth study of the physics and technology of ﬁre suppression processes using these substances. One of the ways to ﬁnd the solution to these problems is the efﬁciency analysis (theoretical and experimental) of frequently implemented ﬁre extinguishing patterns involving ﬁre suppression systems spraying dry powder, when the term of interaction between the dry ﬁre extinguishing powder and the burning material is close to the duration of principal ﬁre extinguishing patterns, or thermal and heterogeneous inhibition of active ﬂame centres.

Purpose and objectives. The purpose of the work was to assess the efﬁciency of principal ﬁre extinguishing patterns (thermal and heterogeneous inhibition of active ﬂame centres) amid non-stable heat exchange processes and heterogeneous inhibition of active combustion product particles by powder particles.

Methods. The pre-set objective was achieved through theoretical modeling of patterns of thermal ﬁre extinguishing and heterogeneous inhibition of active ﬂame centres by dry chemical powder particles.

Results. It was established that ﬁre suppression with the help of general purpose dry chemical powder under non-steady conditions is the more effective, the smaller the effective size of powder particles, the longer the time of their stay in the combustion area and the shorter the characteristic period of heat transfer to powder particles and heterogeneous inhibition of active ﬂame centres.

Conclusions. The results optimize conditions and patterns of dry ﬁre extinguishing powder application to a combustion area to achieve the highest extinguishing effect and to conduct a targeted search for new dry chemical powders having pre-set thermal and physical speciﬁcations.

Authors: Bogdanova V. V. , Kobets O. I.
Published: July 2021

Introduction. The analysis of flame retardants and extinguishing agents used for preventing and extinguishing fires in an ecosystem is carried out. It is shown that at present there are no weatherproof, environmentally friendly and cost effective extinguishing agents capable of stopping wood and peat burning. Purpose and objectives. Development of cost effective and environmentally friendly synthetic agents capable of both flame retarding and extinguishing natural combustible materials. Materials and methods. Synthetic dispersions of ammonium phosphates of two- and three-valence metals, as well as wood and peat fireproofed by them are the object of the study. Physical and chemical properties of synthesis products in comparison with their fire retarding efficiency are examined. Fireproofing, fire extinguishing, as well as physical and chemical properties of synthesized products are determined using GOST-regulated methods of thermal and chemical analysis, scanning electron microscopy and original methods. Results and discussion. The formulation of Kompleksil synthetic compound effective in extinguishing and fireproofing wood and peat is optimized using a full factorial experiment. At the same time, the inflow of volatile nitrogen containing products into the gaseous phase is identified as the dominating burning inhibition process common for natural combustible materials. The weather resistance (preservation of fireproof properties in respect of forest combustible materials at 79 mm precipitation), forest and environment enhancement (improvement of mineral nutrition conditions and growth of forest plant communities) properties of Kompleksil compound are identified. Conclusions. A cost effective synthetic compound based on natural mineral materials showing fireproofing and extinguishing efficiency when protecting forest combustible materials and peat is developed. This compound was tested in the process of extinguishing real wildfires; its weather resistance is identified, and the positive response of forest plant communities to the application of this multiple action compound is registered. The use of Kompleksil allows to reduce time expenditures and fire extinguishing agent consumption when extinguishing wildfires, which significantly reduces material damage.
On specific short circuit parameters of 12 vautomobile electric systems
Authors: Nedobitkov A. I.
Published: July 2021

Introduction. The data presented in the article show that the problem of differentiating primary and secondary short circuits is very important. The purpose of the article is to develop a scientifically grounded research method for copper conductors of automobile electric systems showing signs of a short circuit to identify the cause of its damage in a fire investigation. Materials and methods. The research was conducted with the help of JSM-6390LV scanning electron microscope having an energy dispersive microanalysis unit attached, DuraScan 20 microhardness tester, and Fluke Ti400 infrared thermal imager. Results and discussion. It is experimentally proven that the microhardness of a copper conductor subjected to a primary short circuit differs from that of a copper conductor subjected to an overcurrent or external high temperature. Images of microhardness measurement areas of a copper conductor subjected to a primary short circuit are provided. The results of an energy dispersive analysis and characteristic diagnostic features allowing to establish the cause of the copper conductor damage in case of fire (primary or secondary short circuit) are provided. The temperature of the copper conductor is measured for short circuits that entail sparking and an arc. The applicability of the computational method for determining the conductor temperature in the event of a short circuit is experimentally proved. Conclusions. A differentiation method is proposed for telling primary short circuits from secondary ones arising in copper conductors of automobile electrical systems. It is shown that the microhardness testing method can supplement the scanning electron microscopy method. The results provided in the article can be used by specialists to study copper conductors extracted from burned vehicles in order to identify the mechanism of their damage and, eventually, the cause of the car fire.
Unreceptivity – a phenomenon induced by male accessory gland secretions in female Helicoverpa armigera
Authors: Thyloor Rama , Kiran Tannavi , Manjulakumari Doddamane
Published: July 2021

Unreceptivity, a phenomenon generally observed in female insects following mating, was investigated by simulating a mating situation in Helicoverpa armigera females by injecting male accessory glands and duplex (MAG-duplex) extracts sans sperm. Injection of extracts into the abdomen of virgin females induced unreceptivity. The virgin females started behaving like mated females by rejecting the males by avoiding the advances made by the latter to mate. Unreceptivity was observed in about 93% of the females on the day of injection, which reduced to 82% on the second scotophase compared to controls. However, on the third day, 75% of them reverted back to receptivity that was comparable to virgin count. The Tricine–SDS-PAGE of MAG-duplex of virgin and mated male moths revealed the conspicuous absence of a low molecular weight (< 7 kDa) peptide band in the mated moths, and the possibility of being delivered to female at the time of mating. MALDI-TOF spectra of the same extracts showed the presence of several peptides < 7 kDa, further, the absence of them in mated moths.
A corporate governance and business ethics framework: The case study of bank subsidiaries in an emerging country
Authors: Phaswana Ike , Pelser Theuns
Published: July 2021

As Africa continues to develop as a foreign direct investment (FDI) destination, greater emphasis must be placed on domestic and international regulations seeking to facilitate governance levels (Awolusi, Adeyeye, & Pelser, 2017, p. 195). This study investigated the degree of compliance to 2016 King IV Report on Corporate Governance™ for South Africa (King IV™) principles and recommended practices by 17 sampled Standard Bank African subsidiaries. An extensive literature review of business ethics and corporate governance was performed, focusing on works from Kretzschmar et al. (2012) and Geach (2009). King IV™ recommended practices were used as constructs to measure the level of compliance. To answer the three research questions and meet the three research objectives, a manual questionnaire approach was employed to collect data from 33 respondents that represented 17 Standard Bank African subsidiaries. Reliability of the constructs in the questionnaire was performed using a Cronbach’s alpha (α) with (α) equals 0.857 indicating a high level of internal consistency for the nominal scales used in the questionnaire. Validity was established through the research design and sequential mixed methods employed. Based on the respondents’ feedback the researchers developed the corporate governance and business ethics framework for Standard Bank African subsidiaries incorporating King IV™. The modes of managing morality (MMM) business ethics model (Rossouw & van Vuuren, 2013, p. 58) was fused into the framework. The researchers are of the view that the framework would assist Standard Bank Group in realising its stated purpose. A set of recommendations that would assist the Standard Bank Group in meeting the prescripts of King IV™ are proffered

The Role of Climate Change and Human Factors in Affecting Runoff and Hydrological Drought Characteristics of a Watershed
Authors: Senbeta Tesfaye Belay , Romanowicz Renata
Published: July 2021

The main objective of the study is to evaluate the roles of climate
change and human factors on runoff, baseflow, and hydrological drought
characteristics at a watershed scale. The novelty of the study is to
assess separately the cascading, indirect, accumulative effects of
climate change and human factors on hydrological drought, i.e. runoff
and baseflow. This involved analyzing change points to divide the
available hydrometeorological data into a baseline and a perturbed
period. We applied two hydrological models, SWAT and HBV-light, and two
nonparametric climate elasticity of runoff to identify the contribution
of climate change and human factors in influencing runoff and baseflow
processes. The hydrological models were used to simulate naturalized
runoff and baseflow during the perturbed period. The temporal variation
in the characteristics of the baseflow regime is expressed as baseflow
index. Drought indices, standardized runoff index and standardized
baseflow index were used as hydrological drought indicators. A
significant change in runoff reduction in the Kamienna watershed began
in 1982, suggesting that human factors play a dominant role in
influencing runoff. In addition, we found that an increase in baseflow
and a decrease in hydrological drought events in the 2010s are a
positive long-term effect of human factors such as construction of dams
in the watershed. Finally, analyses of changes in land cover dynamics in
the watershed over the past four decades using satellite imagery are
used to confirm the presence of human interventions.

Rootstocks induce functional differences that affect carbon isotope discrimination and water relations in the apple scion
Authors: Biasuz Erica Casagrande , Kalcsits Lee
Published: July 2021

Composite trees combine traits from both the rootstock and scion.
Dwarfing rootstocks are used to reduce shoot vigor and improve fruit
quality and productivity. Although differences in rootstock vigour have
been clearly described, the underlying physiological mechanisms
regulating scion vigor are not well understood. Plant water status is
strongly influenced by stem hydraulic resistance to water movement. In
the scion, stomata regulate transpiration rates and are essential to
prevent hydraulic failure. Lower stomatal conductance contributes to
enriched leaf carbon isotope composition (δ13C). Combined, the effects
of increased hydraulic resistance, limited stomatal control, and
subsequently, limited gas exchange can affect tree growth. These
differences may also correspond to differences in scion vigor. Here,
vegetative growth, gas exchange, stem water potential, and leaf δ13C
were compared to determine how rootstocks affect scion water relations.
B.9 had the lowest shoot vigor compared to the more vigorous rootstock,
G.890. Similarly, photosynthetic rates were also lower. Rootstock vigor
was closely associated with leaf gas exchange and stem water potential
in the scion and were reflected in leaf δ13C signatures. Dwarfing was
strongly related to hydraulic limitations induced by rootstock genotype
and these changes are distinguishable when measuring leaf and stem δ13C
composition.

Published: July 2021

Introduction. Diabetes mellitus is a chronic disease that affects all aspects
of life of pediatric patients, especially the psychological aspect, and
hence the health-related quality of life. The aim of the study was to
evaluate the effects of sociodemographic and clinical factors of pediatric
patients with type 1 diabetes mellitus on self-assessment of health-related
quality of life. Material and Methods. The research was conducted as a
cross-sectional study. The sample included 37 pediatric patients aged 8 to
18 years, who were diagnosed with the type 1 diabetes mellitus six months or
longer before enrollment into the study. The research instruments used in
the study were the Serbian version of child-friendly EuroQol-5D-Y youth
questionnaire and medical history data (gender, age, time since diagnosis -
in years, glycosylated hemoglobin values, type of insulin therapy). Results.
The total score of general health on the visual analogue scale was 80.54 on
average (standard deviation - 20.87). A negative correlation was found
between the total score on the visual analogue scale and the duration of
diabetes (? = -0.329, p < 0.05). The statistical significance of the
difference in the distribution of respondents? responses in relation to the
type of insulin therapy was confirmed in the domain ?Feeling of concern? (?2
(2) = 7.19, p < 0.05). Conclusion. The key determinants that influenced the
self-assessment of the health-related quality of life in pediatric patients
with type 1 diabetes mellitus are duration of the disease and the use of
insulin analogues.

Published: July 2021

Introduction. Although transcutaneous electrical nerve stimulation and
diadynamic currents are widely used in the treatment of painful conditions,
their effectiveness in acute low back pain is still controversial. The aim
of this study was to evaluate the therapeutic effects of transcutaneous
electrical nerve stimulation and diadynamic current therapy in patients with
acute low back pain. The study was designed as a single-blind randomized
controlled trial. Material and Methods. A total of 60 patients with acute
low back pain, recruited from physiotherapy referrals, were included in the
study. Thirty consecutive patients randomized to receive transcutaneous
electrical nerve stimulation were in the experimental group, and 30 patients
treated with diadynamic current were included in the control group. The
primary outcome variable, measured at days 1 and 10 was pain intensity,
measured using a visual analogue scale. Secondary outcome measures were
lumbosacral spine flexibility (measured by Schober test), lumbar paraspinal
muscle tone evaluated by palpation of the affected paraspinal muscles, and
hip range of motion during the straight leg raise test in the supine
position. Results. All the parameters in each group showed significant
improvements after 10 days of physical therapy (p < 0.01). Statistical
analysis showed that there were significant differences between the groups
in pain relief and sensitivity of paraspinal muscles after the treatment,
mostly due to the experimental group (p < 0.01). Conclusion. In conclusion,
transcutaneous electrical nerve stimulation and diadynamic current therapy
can be used in rehabilitation of patients with acute low back pain, but
transcutaneous electrical nerve stimulation seems to have better pain
modulation effect than diadynamic current therapy.

I investigate constructed social platforms for female jazz instrumentalist,
with a particular emphasis on the Balkan cultural space of Southeastern
Europe (former Yugoslav countries). In this region, female jazz
instrumentalists are confronted with multiple systems of rejection, facing
double standards of the Balkan social-ideological patterns, typical for the
patriarchal tradition, reproduced and incorporated within a micro context of
the already gendered music genre. I analyze the image of female jazz
instrumentalist in the public cultural space where jazz is created and
consumed. This study presents autoethnographic testimonies as a subjective
point of view.
Insulin Resistance in Skeletal Muscle Selectively Protects the Heart in Response to Metabolic Stress

Published: July 2021

Obesity and type 2 diabetes mellitus (T2DM) are the leading causes of cardiovascular morbidity and mortality. Although insulin resistance is believed to underlie these disorders, anecdotal evidence contradicts this common belief. Accordingly, obese patients with cardiovascular disease have better prognoses relative to leaner patients with the same diagnoses, whereas treatment of T2DM patients with thiazolidinedione, one of the popular insulin-sensitizer drugs, significantly increases the risk of heart failure. Using mice with skeletal musclespecific ablation of the insulin receptor gene (MIRKO), we addressed this paradox by demonstrating that insulin signaling in skeletal muscles specifically mediated cross talk with the heart, but not other metabolic tissues, to prevent cardiac dysfunction in response to metabolic stress. Despite severe hyperinsulinemia and aggregating obesity, MIRKO mice were protected from myocardial insulin resistance, mitochondrial dysfunction, and metabolic reprogramming in response to diet-induced obesity. Consequently, the MIRKO mice were also protected from myocardial inflammation, cardiomyopathy, and left ventricle dysfunction. Together, our findings suggest that insulin resistance in skeletal muscle functions as a double-edged sword in metabolic diseases.

Применение кавитации при производстве инвертного сиропа позволяет получать продукт со 100-ной инверсией сахарозы, влажностью 20%, с дисперсностью среды 0,2-0.4 мкм. IScav по сравнению с IS имеет более высокие показатели динамической вязкости, активности воды, и меньшую плотность. Увеличение дисперсности системы приводит к лучшему удержанию влаги помадными конфетами в процессе их хранения (35 сут, 5 оС, негерметично) при соблюдении допустимых нормативных показателей микробиологической безопасности. Помадные конфеты на IScav характеризуются мелкокристаллической текстурой, что обеспечивает им более нежную, таящую во рту консистенцию по сравнению с изделиями на патоке.

How nurse practitioners working in rural communities can reduce the barriers to access primary health care services for older adults
Authors:   , Enes Elizabeth
Published: July 2021

Due to the aging population worldwide, need to access primary health care (PHC) services is increasing. Older adults are at a heightened risk of developing chronic diseases, poor health outcomes, and increased emergency department visits. Living in rural communities also increases the risk of chronicity for older adults due to a lack of PHC resources. However, there is limited information available to provide insight into how healthcare providers can reduce barriers to access to PHC for older adults. As PHC providers, nurse practitioners are in a position to implement strategies to reduce barriers older adults in rural communities face with accessing PHC services. An integrative literature review was conducted to identify barriers nurse practitioners within rural communities can reduce to improve older adults’ access to PHC services. An analysis of the literature revealed the complexity of barriers that prevent older adults from accessing PHC services in rural communities. Environmental, systemic, and individual barriers were reviewed alongside programs and interventions relevant to reducing barriers in the findings. Findings from the literature review suggested strategies to reduce these barriers, which nurse practitioners can promote in the PHC setting. These strategies include virtual care, home visits, nurse practitioner-models of care, interdisciplinary teamwork, and role clarification. In addition to these strategies, implications for practice, limitations of the study and suggestions for future research are discussed.

It is indeed a great misnomer to analyze the dimensions of academic capitalism with the steady rise of entrepreneurial university in lines with Western educational policies. It is indeed a long treaded journey in emerging underdeveloped economies which has given the notion of a dream of the next superpower wherein entrepreneurial universities are a very recent concept post liberalization of economy and change in governmental practices and loosing hold over bureaucratic affairs which has led more stronger the innovation landscape of industry–education–government nexus in building the nation. Recent years have seen the great crisis of COVID pandemic which has changed the ideologies and theoretical models underlying economic welfare states and the velocity of money running through society. Amidst huge literature in entrepreneurial university studies, very little work has been done which answers the very pertinent question and research gap of how the triple helix model arrived in India and how the central government in India changed its beliefs globally by inheriting such model in its innovation practices to champion the cause of bringing new products, economic welfare, product development; which transformed India’s idea of being an importer of healthcare facilities to an expert and exporter of medical facilities thus completely reversing the cycle of trade and global logistics in healthcare economic practices. This paper works on such exploratory case study concerning India’s success story in employing triple helix model of innovation in national policy practices and world economy.
