Chemical Kinship
Authors: Balayannis Angeliki , Garnett Emma
Published: May 2020

Feminist technoscientific research with chemicals is proliferating. This critical commentary considers how this scholarship extends environmental justice research on pollution. We are concerned with two key questions: How can we do/design ethical research with chemicals? And, what methods allow for researching chemicals without resorting to an imagined space of purity? We consider unfolding projects which reorient relations with chemicals from villainous objects with violent effects, to chemical kin. We imagine chemical kinship as a concept, an analytical tool, and a mode of relating. Emerging through feminist and anticolonial work with chemicals, it involves a tentativeness towards making normative claims about chemicals because, like kin, these materials are never entirely good nor bad, at once they can both be enabling and harmful. This commentary considers what the unfolding research with chemicals generates, and consolidates conceptualisations of chemical kinship; we ultimately articulate an agenda for ethical research with chemicals as an experimental process of invention.

TAHAPAN PENGEMBANGAN MORAL: PERSPEKTIF BARAT DAN ISLAM (Telaah Terhadap Gagasan Thomas Lickona, Lawrence Kohlberg dan Al-Qur’an)
Authors: Kuswandi Iwan
Published: May 2020

A decline in moral is among the impacts of technological development. For this reason, Thomas Lickona and Lawrence Kohlberg developed a concept of moral development, a concept which has also been discussed in the Holy Quran. Lickona stated that moral development stages are started with the ownership of moral knowledge (moral knowing) and move to moral feeling and moral action. Kohlberg stated that there are six stages in moral development. The stages are in three phases. First phase is called pre-conventional, which consists of stage 1 and stage 2. In this phase, people are more concerned about being right and wrong and getting reward or punishment. The next phase is called conventional phase, which consists of stage 3 and stage 4. In this level, people are more driven by internal motivation and how they are perceived by society. The final phase is post conventional phase, consisting of stage 5 and stage 6. In this level, people are able to independently interpret moral values and are driven by more universal values. The Quran divided the stages into some classes which are mentioned as ulul ilm (those of knowledge), ulin nuha (those of intelligence), ulil abshar (those of vision), ulil albab (those of understanding), ulil amri (those in authority), ulil aidi (those of strength) dan ulil azmi (those of determination).

KONSEP AL HIKMAH DALAM FILSAFAT MULLA SADRA
Authors: Khosiah Nur
Published: May 2020

Mulla Sadra had the full name of Shadr Al-Din Muhammad Ibn Ibrahim Ibn Yahya Qawami Al-Syirazi. He was born in 1572 A.D. in Syiraz. From the relatively long Mulla Sadra's life of approximately seventy years, it can be divided into three different periods. First, the childhood and school periods in Syiraz and Isfahan. Secondly, the period of asceticism near Qum and the third, the teaching and writing period that presented the results and the fruits of the two previous periods. In his major work al-Hikmah al-Muta'aliyah fi al-Asfar al-Aqliyah al-Arba'ah, Sadra outlines the whole issue of Islamic philosophy, of the nature of God, the nature of the universe and the fate of mankind. One of the important and interesting of Sadra is his view of the movement of the Subatansi (al-Harakah al-Jauhariyah) that speaks of the occurrence of changes in the form of the universe.
AKAR MODERASI BERAGAMA DI PESANTREN (Studi Kasus di Ma’had Aly Sukorejo Situbondo dalam Terbentuknya Nilai-Nilai Moderasi Beragama)
Authors: Aziz Abdul
Published: May 2020

Religious moderation is increasingly intensified to compensate some groups who continue to make the religious issues as object of conflict. The issue of religion is made as a commodity for political interests, even though Islam has been moderate since its inception. There is a lot of concrete evidence to show that Islam is a moderate religion. Become the mediator of religions that have been held before. Actually, when examined the moderation of Islam it has been built for a long time in Indonesia, especially in the world of islamic boarding school (pesantren). Including in Ma'had Aly (MA) Situbondo, as the institution that takes the Fiqh and Ushul Fiqh for its focus of learning studies, which is under the authority of the Salafiyah Syafi'iyah Islamic Boarding School Sukorejo Situbondo. Seeing the results of their discussion, which stated in Tanwirul Afkar Magazine, it can be seen that they are very moderate. The Fiqh that they convey is not only seen as a product, but also as a process, and that become the reason for their reasoning power of ushuly is always appears. The proposition is not only textual, but it is also contextual. Therefore from this good struggle with various kinds of fiqh madzhab and strengthened by the concept of ushul fiqh they had mastered make the moderate character formed by well.

Authors: Matus P. P. , Lemeshevsky S. V.
Published: May 2020

The stability with respect to coefficients of solution of a difference scheme approximating the initial boundary-value problem for the one-dimensional semi-linear hyperbolic equation is studied. The estimates of the solutions of both differential and difference problems are obtained. In the domain of existence of the solution, the estimates for perturbation of the solution of a difference scheme with respect to perturbation of the coefficients of the equation are obtained. These estimates are consistent with the estimates for the differential problem. In all cases, the method of energy inequalities, the Bihari inequality and its mesh analogue are used.

Published: May 2020

Hydrogel negatively charged (–13.5 ± 5.0 mV) calcium pectinate nano- and submicroparticles (50–150 nm) were obtained. A technique for entrapment of a plant growth regulator (trans-cinnamic acid) in the particles up to 40 wt. % has been developed. It has been established that the complete release of trans-cinnamic acid in the Murashige–Skoog medium takes 2.5 hours. The obtained particles of calcium pectinate do not affect the growth processes of cells in suspension culture and can be used as neutral carriers for growth regulators.

Published: May 2020

The connective tissue sheaths of paravertebral tendons (peritenons) of white laboratory rats treated with silicon dioxide and hyaluronic acid were studied. It was found that peritenones are natural composites with orthogonal anisotropy with a developed system of interstitial porous membranes that regulate tissue hydrodynamic flows. The extracellular matrix of peritenons contains carbonate-hydroxyapatite and calcium hydroxide in the amorphized state. Silicon dioxide and hyaluronate form hydrophobic silicate and hyaluronate coatings of collagen fibrils (encapsulation), strengthen bonds in Amides I, II, III, reduce the intensity of the bands of bound hydroxyl and stretching vibration bands of phosphate groups, which indicates the replacement of OH groups with carbonate ions and the suppression synthesis of hydroxyapatite. A key mechanism for reducing the intensity of apatitogenesis is the encapsulation of collagen fibrils, accompanied by screening the centers of epitaxial interactions that are structured during heterogeneous nucleation of calcium phosphates. In SBF biomimetic fluid, the deforming effect of modifying agents is leveled, but hydration and decomposition of fibrillar collagen increase. Moreover, against the background of excess supply of exogenous phosphates and carbonates from SBF, apatitogenesis in peritenons is carried out mainly by the mechanism of homogeneous nucleation.

Published: May 2020

The genes of the major histocompatibility complex (HLA) play a significant role in the genetic predisposition to juvenile idiopathic arthritis (JIA) and determine up to 18 % of disease risk. This work was aimed to reveal associations of the HLA characteristic pattern with two clinically different forms of JIA in the Belarusian population. 24 patients diagnosed with systemic JIA, 24 patients with oligoarticular JIA and 24 healthy controls were included into the study. High-throughput HLA typing for 11 loci was performed using TruSight HLA v2 Sequencing Panel (Illumina) on the MiSeq system. DQB1*04:02:01 (p = 0.026; OR 5.88 [1.20–28.72]), DRB1*08:01:01 (p = 0.07; OR 3.94 [1.01–15.39]) and DR8-haplotype (p = 0.006; OR 3.95 [1.34–11.63]) frequencies were significantly higher in patients with oligoarthritis but not systemic JIA when compared with controls. While DQA1*05:01:01 and DQB1*02:01:01 alleles showed a protective effect against both systemic (p = 0.007, OR 0.08 [0.009–0.65]; p = 0.01, OR 0.09 [0.01–0.83]) and oliarticular JIA (p = 0.026, OR 0.16 [0.03–0.79]; p = 0.046, OR 0.2 [0.04–1.00], the negative association of the DRB1*03:01 allele was revealed only for systemic JIA (p = 0.03, OR 0.11 [0.01–0.88]). Thus, the obtained results suggest that different HLA-patterns are involved into the formation of various JIA subtypes.

Authors: Sheiko R. I. , Kazarovets I. N.
Published: May 2020

Global experience related to increased pork production shows that breeding work has become an integral part of the technology, since it is impossible to further improve breeding and performance traits of animals without it and therefore the greater production of better quality pork. The paper presents the results of the breeding process arrangement for creation of F1 parental pig. Substantiation of breeding techniques when creating the final parental groups of sows (F1) with a high adaptive ability was based on complex methods to evaluate breeding animals, including traditional methods of domestic breeding and breeding indices. Evaluation of combination compatibility of breed-linear hybrids with the use of breeding indices during mating of parent initial forms allows to determine efficiency of using Yorkshire sows with Landrace boars, and Landrace sows with Yorkshire boars (final parental sows (F1)), which had significantly better reproductive indicators in comparison with BLW х BM genotype sows. Particularly efficient compatibility was recorded when selecting Yorkshire sows and Landrace boars. It was determined that in modern conditions an increase in the efficiency of breeding and pedigree work in pig breeding was based on the use of genetic methods, including: individual assessment of pedigree species according to the main breeding traits, evaluation of genome of each breeding animal, and use of breeding indices allowing to identify the true genetic potential of animals and predict performance traits of their offspring. The research relevance lies in using the innovative methodology for comprehensive assessment of combination compatibility of parental pairs, unified for pig husbandries and pig farms, which will make it possible to 10% accelerate the breeding process of forming the final parental forms of sows, ensure obtaining offspring with predictable reproductive, fattening and meat traits, and good adaptive ability.

The paper is the fundamental beginning of research series aimed at understanding the processes associated with high performance in higher animals. The research aim is to study correlation of dicarboxylic acid cycle with tricarboxylic acid cycle with establishment of activity and dislocation of enzymes, confirming the hypothesis of availability and active metabolic participation of peroxisome in highly productive animals. Research was conducted on the basis of the VNIIFBiP animal vivarium in 2019 with a group of piglets of the Irish Landrace breed (n = 10). After slaughter at the age of 210 days, the nuclear (with large tissue particles), mitochondrial and postmitochondrial fractions of the liver were studied with assessment of succinate dehydrogenase and activity of other dehydrogenes of the Krebs cycle. It was found that peroxisomes act as universal agents of communication and cooperation, and microtelets are able to generate various chemical signals that carry information, to control and arrange a number of mechanisms in the metabolic processes in the body. Despite the fact that the Krebs cycle dehydrogenases are considered mitochondrial enzymes, the experiment showed an increase in activity of priruvate dehydrogenase (P > 0.1), isocitrate dehydrogenase (0.1 > P > 0.05) and malate dehydrogenase (0.1 > P > 0.05), which, when comparing the mitochondrial and postmitochondrial fractions, indicates a higher activity of peroxisomal fractions. The peroxisome localization place is the postmitochondrial fraction, and the lower layer contains larger peroxisomes to a greater extent, while the upper layer contains smaller ones. It was found that indicator enzymes of glyoxylate cycle isocitratliase and malate synthase exhibit catalytic activity in the peroxisomal fraction of liver of highly productive pigs. The obtained data on functioning of key glyoxylate cycle enzymes and their intracellular compartmentalization in highly productive pigs allow learning more about the specifics of metabolism and its regulation processes. Application of this knowledge in practice opens up prospects for rationalizing the production of livestock products of increased quantity, improved quality with less feed, labor and financial resources spent.

Published: May 2020

High dairy performance of adult animals is directly dependent on the conditions of calves growing and feeding during the preweaning period. Since cattle has a low so-called “critical temperature”, it is advisable to use this property of the body when rearing calves in the open air year-round in individual houses. It is known that among the entire complex of factors affecting the intensive growth of calves, the quality of food and the method of calves feeding in the first periods of postembryonic development of young animals from birth to 12 months deserve the most attention. In order to reduce consumption of whole milk for feeding calves and accelerate development of digestive tract in calves in early life period with high body weight gains, in practice specialists try to achieve it by introducing plant foods into diets for calves. However, plant feeds, even high-energy ones (cereals and legumes), containing large amount of protein, carbohydrates, starch, etc., are digested by calves very slowly and in small quantities. It is shown that to eliminate these drawbacks it is advisable to extrude all the plant feeds. The paper describes in detail the technology and equipment for preparing easily digestible feeds based on legumes for calves feeding during preweaning period, allowing to accelerate the development of digestive tract in the early life period of calves with high body weight gains, reduce consumption of whole milk or its replacers and energy costs for its production. Studies on the effect of feeding young cattle with feed concentrate during preweaning period showed increase in performance by 6.6 % and a decrease in feed costs by 5.73 %.
Process of pasta products forming in matrix wells with pre-compaction, plasticization and heating of dough
Authors: Grudanov V. Ya. , Torhan A. B. , Stankevich P. V.
Published: May 2020

The existing designs of domestic and foreign matrices lack pre-compaction, plasticization and heating of dough, which leads to significant hydraulic resistance in the area where dough flow enters the forming holes of the dies and increases energy consumption, while in typical matrices the cross section of deep and empty wells is much larger than the total area of forming holes. The dough flow almost becomes uncontrollable, and this leads to water hammer effect and destruction of dies. This problem can be solved by installing special inserts in in the matrix wells (depth of wells is 50-120 mm). The paper shows a new direction in design of matrices for production of pasta, in particular, it is proposed to install spiral inserts in the wells of matrix, manufactured in the form of Venturi tubes. Rheological basis of dough flow in the cylindrical channels of the insert are considered, mathematical models for determination of the dough volume flow rate and dough flow rate are constructed. It is theoretically established that the volume flow rate of the dough Q0 and its flow rate depend on the length of the cylindrical channel and the viscosity of dough. The results of experimental researches are presented. It is empirically established that the inserts located in the wells of the matrix pre-compact dough, plasticize and heat it, the productivity of the press machine MIT-2 due to increasing the speed of extrusion is increased averagely by 25-26 % with significant improvement in quality of the formed semi-finished products and reduction of energy consumption.
Verbs with the value of ‘to give a sign, called motivating adjective’ in the composition nominative series in Russian and Belarusian languages
Authors: Lavysh M. A.
Published: May 2020

The article deals with the nominative series of verbs formed from adjectives that implement the value of “to give a sign” in Russian and Belarusian languages. Special attention is paid to the study of equivalent derivational combinations that make up the nominative series of such verbs, their functioning in closely related languages. The most regular discrete correspondence of causative verbs is a fairly simple derivational model “do what”, while the analytical structures may include related units not only belonging to different parts of speech, but also separated from the motivating adjective by several steps of productivity. Other types of phrases actively participating in the derivational function can also take part in organizing nominative series. The study revealed whole microsystems of incomplete nominative series: with a synthetic or analytical component. Detailed analysis of such nominative series allows us to identify various causes of its occurrence (semantic, formal, stylistic). Significant differences in the derivational potential of adjective verbs in the Russian and Belarusian languages can be found not only in the semantic-word-formation of specific word-formation pairs, but also in later stages of derivation, as part of more complex associations of related units, different fragments of derivational nests (word-formation chains, paradigms).

This project is based on the design and construction of an industrial air conditioning system for the improvement of the working thermal comfort of workers that for various reasons there is the trend of the increase in body temperature are these by machines, equipment or the same work activities, which affects the productive performance and possible health risks. During development, the selection of mechanical equipment such as the fan, water pump, ventilation transport ducts is studied with high rates of energy efficiency. In the light of the above, the environmental economic partner alternative is chosen to implement the evaporative conditioning system, conducive to working in open places to lower the temperature by labor and technology installed in the production areas, as well as the extraction of fumes derived from production processes. The importance of the evaporative conditioning system is to derive the appropriate mechanisms to take advantage of the surface heat transfer of a panel and copper and aluminum coil using water, and thus take advantage of its temperature differential reaching 25oC, with an average humidity of 66% and energy consumption of 0.29 KW/h.

Authors: Okunye OL , Kotun BC , Kolade-Titilayo T
Published: May 2020

Background: Automated Teller Machines (ATM) are interactive physical platforms that respond to touch command of the user when an account holder inserts a coded bank card. They are operated with finger impressions of bank customers after insertion of the coded card.

Objective: To determine the prevalence of isolates, quantify and determine the susceptibility of the isolates to conventional antibiotics and to test the efficacy of disinfectants on the bacterial isolates from these selected ATMs.

Methods: Ten(10) ATMs were selected per Local Government Areas (LGA) in five LGA. Sterile swab impregnated with physiological saline was aseptically impressed and rolled over the keypad and screens of the ATMs. The swabs were inoculated in peptone broth and incubated for 24 to 48hours. The inoculums from the broth were streaked on five (5) different selective agar media and standard biochemical tests were used to confirm the bacterial isolates.

Results: The prevalence rates of the bacterial agents found on the ATMs were as follows: Staphylococcus aureus (30; 60%), Coagulase-Negative Staphylococcus spp (10; 20%), Pseudomonas spp (16; 32%), and Streptococcus spp (20; 40%) respectively. Antibiogram was carried on biochemically identified isolates, and most of the isolates showed varied susceptibility to the antibiotics and the disinfectants tested.

Conclusion: Multiple bacterial isolates found in this study have the potential to attain pathogenic status in compromised hosts and the possibility of transmission of these isolates from one user to another is a challenge of epidemiological magnitude.

Authors: Folarin R , Adefoluke S , Ogunwale T , Osinowo O , Ogunledun A , Ibrahim I
Published: May 2020

Background: Attention Deficit and Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder associated with pre-fronto-cortical (PFC) cognitive dysfunctions. Ethanol is a psychoactive agent and its foetal exposure is employed in the modelling of ADHD.

Objective: To determine the curative roles of Nigella sativa in the PFC functions of mice induced with ADHD-like symptoms.

Method: Twelve BALB/c mice pups each from four groups of dams were studied. Normal saline was administered to the control (CTRL) dams, ethanol to the ETH dams, Nigella Sativa to the NS dams, and Nigella sativa followed with ethanol to the NSE dams. Novel object recognition test was used to assess recognition memory in the pups 15 days after weaning. Histological illustration of PFC was conducted using haematoxylin and eosin (H&E) stain.

Results: ETH mice exhibited the least recognition memory while Nigella sativa prevented this deficit in NSE mice by eliciting much higher recognition memory. This indicates the neuroprotective role of Nigella sativa despite prenatal exposure. NS pups also had the highest weight gain, as well as the glutamate and Glutathione, peroxidase (GPX) levels, while raising these levels in the ETH-exposed mice which had the lowest levels, indicating a neurochemical potentiation. The results of the histological analysis showed the protective roles of Nigella sativa on the PFC neuronal densities.

Conclusion: This study suggests the protective effects of Nigella sativa on the prefronto-cortical functions in mice ADHD model following maternal exposure to ethanol.

Published: May 2020

Background: Insulin resistance (IR) is linked with the pathophysiology of some non-communicable diseases including Type 2 Diabetes mellitus and metabolic syndrome. Objective: To determine the factors associated with IR among apparently healthy individuals in South-west Nigeria. Methods: A cross-sectional study of a cohort of apparently healthy volunteers aged 18 years and above consecutively recruited from two communities was conducted. IR was determined using the homeostasis model assessment for IR (HOMA-IR) based on the cut off values of ≥ 2. Bivariate and multivariate analyses were used to determine the crude and adjusted odds ratio of IR associated factors. Results: A total of 520 participants aged 18–89 years were recruited for the study. Their mean age was 46.7±14.6 years and the prevalence of IR was 43.5%. Alcohol intake (AOR = 2.1, 95%CI 1.3 – 3.4; p<0.001), lack of physical exercise (AOR = 1.5, 95%CI 1.0 – 2.3), and Body Mass Index (AOR = 1.03, 95%CI 1.0 – 1.1) were the factors associated with IR. Conclusion: The prevalence of IR among apparently healthy individuals in this study was high. The need for proactive measures to avert the sequelae of IR is of utmost importance.

Published: May 2020

Background: The superimposition of the morbidity of cardiac diseases on the physiological demands of pregnancy could impact adversely on pregnancy outcomes. Therefore, contemporary information is for appropriate clinical management. Objective: To determine the management outcomes of cardiac diseases in pregnancy at the Obafemi Awolowo University Teaching Hospitals Complex (OAUTHC), Ile-Ife. Methods: A retrospective review of the hospital records of patients with cardiac diseases in pregnancy between January 2006 and December 2015 was conducted. The age, parity, gestational age at admission, NYHA class, clinical diagnosis, the results of investigations, complications of cardiac diseases, and maternal and foetal outcomes were recorded. Results: There were 33 women with cardiac diseases in pregnancy and 11,352 deliveries within the period, giving an incidence of 2.9 per 1000. Further analysis was based on 24 women with complete records. The mean age of the patients was 29.2±5.5 years. Twenty (83%) of the women were Para 2 or less, while 13 (54%) presented postpartum. The majority of the women (15; 62.5%) had peripartum cardiomyopathy, while 17 (71%) had NYHA Class III or IV disease. Thirteen (54%) women had vaginal delivery. There were four perinatal and two maternal deaths, with a perinatal mortality rate of 166/1,000 total births and maternal mortality ratio of 8,333/100,000 live births. Conclusion: Cardiac diseases in pregnancy are associated with high perinatal and maternal mortality rates at the OAUTHC, Ile-Ife. However, with early diagnosis and appropriate care, the majority of the patients had a satisfactory clinical outcome. Early presentation and advocacy to improve health-seeking behaviour are recommended.

Authors: Mbuthia OW , Ndonga EN , Odiwour SO , Muraguri MW
Published: May 2020

Background: Globally, there has been an overall decline in the effectiveness of antibiotics resulting in an upsurge in bacterial resistance, increased cost of healthcare and consequent high morbidity and mortality rates.

Objective: To determine antibiotic prescription practices among healthcare workers at the Kenyatta National Hospital, Mbagathi, Pumwani Maternity and Mama Lucy Kibaki Hospitals, Nairobi, Kenya.

Methods: The study design was a mixture of quantitative and qualitative methods. Self-administered questionnaires were used to gather information from 230 prescribing healthcare workers. Interviews and Focus Group Discussions (FGDs) were conducted purposively with the prescribing healthcare workers and patients to obtain qualitative data.

Results: There was a significant difference in the distribution of study participants with regards to the availability of antibiotics prescribing policy (p = 0.05). Only 53 (23%) prescribers prescribed antibiotics as per the policy guide while 51 (22.2%) did not and 126 (54.8%) were not sure. Oral antibiotics (OR = 0.5, 95%CI 0.3-0.9), always referring to the 2016 Kenya Essential Medicines List (KEML) to prescribe antibiotics (OR = 4.2, 95%CI 1.3-13.1), separating antibiograms for inpatient and outpatient departments (OR = 4.3, 95%CI 1.11-15.5), and confidence of healthcare workers to prescribe antibiotics without laboratory tests (OR = 0.3, 95%CI 0.2-0.8) were associated with the prescription of antibiotics.

Conclusion: There is need to improve antibiotic prescription practices among healthcare workers in public tertiary hospitals in Nairobi County to promote rational antibiotic use and control bacterial resistance.

Long-term sea level rise (SLR) leads to increasing frequency in overtopping events resulting from polar ice liquefaction triggered by rising global temperatures. Aceh province is directly bordered by the Indian Ocean, and is subject to the influence of ocean–atmosphere interactions which have a role in triggering temperature and sea level anomalies. Elevated sea level is possibly caused by temperature-induced water mass redistributions. This study aimed to prove that the Indian Ocean Dipole (IOD) and El-Nino–Southern Oscillation (ENSO) had an influence on sea level change in Aceh waters over the six years 2009–2015. Sea level anomaly (SLA) was identified using Jason-2 satellite data for the 2009–2015 period, to enable the mathematical prediction of SLR rate for further years. We found that SLR was approximately 0.0095 mm/year with an upward trend during the six years of observation. Overall, negative mode of IOD and positive phase of ENSO tend to trigger anomalies of sea level at certain times, and have a stronger influence on increasing SLA and sea surface temperature anomaly (SSTA) which takes place in a ‘see-saw’ fashion. Over the period of observation, the strongest evidence of IOD-correlated SLA, ENSO-correlated SLA and SSTA-correlated SLA were identified in second transitional seasons, with more than 50% of R2 value. The upward trend in SLA is influenced by climatic factors that successively control ocean–atmosphere interactions in Aceh’s marine waters.

The production of the Indonesian Institute for Marine Research and Observation’s mapping of forecast fishing areas (peta prakiraan daerah penangkapan ikan or PPDPI) based on passive satellite imagery is often constrained by high-cloud-cover issues, which lead to sub-optimal results. This study examines the use of the rolling mosaic method for providing geophysical variables, in particular, seasurface temperature (STT) together with minimum cloud cover, to enable clearer identification of oceanographic conditions. The analysis was carried out in contrasting seasons: dry season in July 2018 and rainy season in December 2018. In general, the rolling mosaic method is able to reduce cloud cover for sea-surface temperature (SST) data. A longer time range will increase the coverage percentage (CP) of SST data. In July, the CP of SST data increased significantly, from 15.3 % to 30.29% for the reference 1D mosaic and up to 84.19 % to 89.07% for the 14D mosaic. In contrast, the CP of SST data in December tended to be lower, from 4.93 % to 13.03% in the 1D mosaic to 41.48 % to 51.60% in the14D mosaic. However, the longer time range decreases the relationship between the reference SST data and rolling mosaic method data. A strong relationship lies between the 1D mosaic and 3D mosaics, with correlation coefficients of 0.984 for July and 0.945 for December. Furthermore, a longer time range will decrease root mean square error (RMSE) values. In July, RMSE decreased from 0.288°C (3D mosaic) to 0.471°C (14D mosaic). The RMSE value in December decreased from 0.387°C (3D mosaic) to 0.477°C (14D mosaic). Based on scoring analysis of CP, correlation coefficient and RMSE value, results indicate that the 7D mosaic method is useful for providing low-cloud-coverage SST data for PPDPI production in the dry season, while the 14D mosaic method is suitable for the rainy season.

Published: May 2020

In the process of functioning working sets with electromechanical converters included in their composition, it is necessary to take into account the influence of endogenous and exogenous disturbances that cause deviations of the parameters of electric machines from the nominal values given by the manufacturer in the appropriate documentation. These deviations of the parameters, even those within the permissible range of changes, have a noticeable effect on the quality of functioning of electromechanical converters and working sets as a whole. During the life cycle of the work of electromechanical converters, their parameters change as a result of natural wear and senescence, which necessitates continuous or periodic analysis and monitoring of the state objects under study. The paper considers a method based on the calculation of the linear integral criterion Q and the formation of Q – tables, which allows monitoring the functioning of electromechanical converters with unstable parameters during operation as part of working sets. Simulink – models of linear integral criterion calculation system and system of automated monitoring of electromechanical DC converter parameters are presented, which allow estimating unstable parameters. In these models static characteristics are implemented in tabular form reflecting the dependencies between the parameters of the electromechanical converters and the linear integral criterion. The results of the study allow us to obtain estimates of changes in the unstable parameters of electromechanical DC converters with the required accuracy.

At high ambient temperatures, the performance of gas turbine power plants drops significantly. Technical solutions of compensation for losses associated with the constant injection of water into the air intake of a gas turbine. This approach is not acceptable in regions with limited fresh water reserves. Radical solutions are required to reduce the cost of generated energy. Integrated Combined Solar Cycle (ISCCS) technology has proven itself on many projects. The addition of a combined cycle gas cycle with solar energy can significantly increase the overall efficiency of the power plant. Despite the increase in costs during the construction of its solar part, the total cost of operating solar collectors is several times less than a turbine installation. Given the global trend to fight carbon emissions, switching to a hybrid scheme is economically attractive. Trading in carbon credits for CO2 emissions will significantly reduce the payback period for the construction of gas turbine modernization under the ISCCS scheme. This paper presents an option to modernize a gas turbine power plant in the city of Basra (Iraq), using the advantages of solar radiation and recycling of combustion products from gas turbines. It is proposed to equip the existing 200 MW gas turbine plant with two steam turbine units with a capacity of 75 and 65 MW, working in conjunction with solar collectors producing low pressure water vapor. Due to modernization, the efficiency of the power plant should increase from 38% to 55%. The revision of the schematic and technical solutions of Iraq power plants will allow producing sufficient energy for the region.

Much attention is paid to the consideration of the causes of transformer oil aging under the influence of technogenic and natural factors. The paper insulation destruction mechanism is considered, as a result of which furan compounds are formed that enter the transformer oil and worsen its dielectric characteristics. The characteristics of the domestic transformer oil grade GK-1 obtained using the technology of hydrocracking in a hydrogen medium are given. Furan compounds are formed in used transformer oil, which are monitored using chromatographic analysis methods according to standard procedures. The group composition of transformer oil was determined using thin layer chromatography. As a solvent used n. Hexane. To extract furan compounds from transformer oil, various organic solvents are used, the physicochemical properties of which are given in this work. It was found that the retention time of the studied sorbates corresponds to an increase in their boiling points for ethyl acetate, methyl ethyl ketone and dodecane. In the case of isopropanol, which has a close boiling point with ethyl acetate and methyl ethyl ketone, a significant increase in retention time is observed, which is associated with the formation of an intermolecular hydrogen bond. The dependence of the spot diameter of furan substances on their concentration was established under conditions of thin-layer chromatography on Sorbfil plastics. Moreover, the most effective separation is characteristic of furfural. In this case, the chromatographic spots are small in size with good fidelity. The ascending mode of column liquid chromatography was used to determine the dependence of the retention time of standard sorbates on the length of the Silyochrome S-80 sorption layer, which is parabolic. It was found that the highest retention times are characteristic of ethoxyethanol and isopropanol, which is consistent with the known theoretical principles of liquid chromatography. Histograms of the effect of the retention time of standard sorbates on their nature and boiling point, where isopropanol and 2-ethoxyethanol are extreme, are presented. In this case, isopropanol having a lower boiling point than 2-Ethoxyethanol is retained on the sorbent more strongly, which is associated with the formation of intermolecular hydrogen bonds with surface silanol groups of the sorbent.

Reliability of power supply of consumers is an important task in the process of transmission and distribution of electric energy. The paper proposes a method for assessing the consequences of power failures of monoconsumers of electric energy on the example of an oil company and an adjacent power grid company. The uniqueness of the developed technique lies in the possibility of reliable calculation of reliability of power supply of complex branched electric networks without taking into account the specific scheme of power supply. The accuracy of calculations is increased due to the use of data directly studied power system, taking into account the specifics and operating conditions of specific equipment, instead of the average information. Classification of failures on the main reasons in electric networks of the oilproducing enterprise of the far North that allowed to develop actions for increase of level of reliability of power supply is made.
