Published: April 2020

A hydroponic study was conducted to evaluate the performance of fivesunflower hybrids, i.e., PARSUN, SH-3322, XF-4623, SMH-9706 and XF- 4619, at 0, 75 and 150 mM NaCl salinity in root medium. Sunflower (Helianthusannuus L.) seeds were germinated in moist quartz sand, twelve-day old seedlings were foam plugged in lids of plastic pots containing 2.5 l of continuosly aerated half-strength Hoagland’s nutrient solution. The experiment was organized in completely randomized design (CRD) using four replications. Sunflower growth deceased drastically with increasing concentration of NaCl in root medium. Sunflower hybrid XF-4619 registered maximum shoot and root fresh weight, stem diameter and leaf area. Furthermore XF-4619 exhibited the least decrease in these parameters under saline conditions. XF-4619 exhibited 14 and 53% decrease in shoot fresh weight, 11 and 35% decrease in root fresh weight, 6 and 34% decrease in stem length, 12 and 34% decrease in stem diameter, 10 and 40% decrease in leaf area, 2 and 31% decrease in root dry matter and 13 and 50% decrease in shoot dry matter yield at 75 and 150 mM NaCl, respectively, as compared with the control. Moreover, Ca and K were also efficiently taken up by XF-4619 in saline and non-saline root medium. This is indicative of it having better yield potential than the other commercial sunflower hybrids.
Modeling the low-velocity impact characteristics of woven glass epoxy composite laminates using artificial neural networks
Authors: Mathivanan N. Rajesh , Mouli Chandra
Published: April 2020

In this work, a new methodology based on artificial neural networks (ANN) has been developed to study the low-velocity impact characteristics of woven glass epoxy laminates of EP3 grade. To train and test the networks, multiple impact cases have been generated using statistical analysis of variance (ANOVA). Experimental tests were performed using an instrumented falling-weight impact-testing machine. Different impact velocities and impact energies on different thicknesses of laminates were considered as the input parameters of the ANN model. This model is a feed-forward back-propagation neural network. Using the input/output data of the experiments, the model was trained and tested. Further, the effects of the low-velocity impact response of the laminates at different energy levels were investigated by studying the cause-effect relationship among the influential factors using response surface methodology. The most significant parameter is determined from the other input variables through ANOVA.
Analytical solution for shear bands in cold-rolled 1018 steel
Authors: Voyiadjis George Z. , Almasri Amin H. , Faghihi Danial , Palazotto Anthony N.
Published: April 2020

Cold-rolled 1018 (CR-1018) carbon steel has been well known for its susceptibility to adiabatic shear banding under dynamic loadings. Analysis of these localizations highly depends on the selection of the constitutive model. To deal with this issue, a constitutive model that takes temperature and strain rate effect into account is proposed. The model is motivated by two physical-based models: the Zerilli and Armstrong and the Voyiadjis and Abed models. This material model, however, incorporates a simple softening term that is capable of simulating the softening behavior of CR-1018 steel. Instability, localization, and evolution of adiabatic shear bands are discussed and presented graphically. In addition, the effect of hydrostatic pressure is illustrated.
Diffusion of a self-interstitial atom in an ultrathin fcc film bonded to a rigid substrate
Authors: Shodja Hossein M. , Tabatabaei Maryam , Pahlevani Ladan , Ostadhossein Alireza
Published: April 2020

The determination of the interstitial sites and saddle points corresponding to the diffusion of an interstitial atom in ultrathin face-centered cubic (fcc) film is of particular interest. The outcome is strongly influenced not only by the orientation of the free surface but also by the location of the defect with respect to the free surface and film-rigid substrate interface. In this article, an atomic-scale simulation is conducted to analyze the effects of depth on the out-of-plane interstitial mechanism of diffusion. To ensure reasonable accuracy and numerical convergence, the atomic interaction up to the second-nearest neighbor is considered. The ab initio examination of the above-mentioned problem associated with thin films requires a large supercell and is computationally time consuming. However, for the sake of demonstration, the values of the barrier height energy pertinent to a diffusing self-interstitial atom in the bulk material are computed using both the first principles density functional theory (DFT) and the developed technique, indicating reasonable correspondence.
The critical size of brittle solid materials and the measurement of their surface tension
Authors: Stamboliadis Elias
Published: April 2020

The relationship of the energy required to break a particle or a particulate material vs. particle size has been studied by many researchers. On the one hand, mineral processing engineers, who are interested in the specific energy (in joules per cubic meter or joules per kilogram) required for grinding, almost agree that it is inversely proportional to the particle size, although they might disagree on the type of the relationship. On the other hand, building and structural engineers, who are mainly interested in the strength of materials (in newtons per square meter or pascals), they almost agree that at the size range of the elements used, their strength depends on the quality of the material rather than its size. The present article shows that both groups of engineers are right about the size range of the bodies used by each one. However, there is a critical size that determines the fracture behavior of a brittle material. The definition of the critical size can be used to understand the practical results obtained as well as to measure the surface tension of the tested materials.
Single crystal plasticity theories predicting bounded lattice rotation under simple shear deformation
Authors: Broese Carsten , Tsakmakis Charalampos
Published: April 2020

Up to now, models for single crystal plasticity predict unbounded lattice rotations under simple shear. Asaro et al. proposed a model that predicts bounded rotations as long as the viscosity parameters are appropriately chosen. In every case, ideal plasticity models imply unbounded lattice rotations. Hence, it leads to the question whether one can develop a single crystal plasticity theory exhibiting hardening effects, which can predict bounded lattice rotations dependent on the choice of the hardening parameters. It is shown that this is possible by assuming latent hardening to apply.
Theoretical limits on barreling of cylinders under axisymmetric compression
Authors: Fournier Jorge L. Velez , Banerjee Jayanta K.
Published: April 2020

A theoretical analysis on three different geometrical limits during axial compression of a cylindrical workpiece under monotonically increasing external load is presented. Barreling is the main factor in metalworking industries, and it depends highly on several dimensional ratios such as initial aspect ratio (height/diameter), work/platen contact diameter ratios, etc. For a known material, barreling can be predicted from the mathematical formulations on the geometrical limits presented herein.

Thirty-Five Years of Peer-Reviewed Publishing by North American Economics PhDs: Quantity, Quality, and Beyond
Authors: Önder Ali Sina , Yilmazkuday Hakan
Published: April 2020

We provide a descriptive analysis of various qualities of peer-reviewed journal publications of graduates of North American economics PhD programs between 1980 and 2014. We find that the share of single-author papers in all published papers diminishes from 60% in 1980 to 50% in 1990 and then further down to 20% in 2014. All-female and mixed-gender author teams publish significantly less compared with all-male author teams between 1980 and 1999, but we find no significant difference after 2000. While male authors are over-represented in micro and macroeconomics, female authors are over-represented in labor and development economics. Although the quality of outlets for most fields does not change much over years, labor economics and economic history are published significantly better after 2000.
Platinum organometallic compounds: classification and analysis of crystallographic and structural data of monomeric five and higher coordinated
Authors: Melník Milan , Mikuš Peter , Holloway Clive Eduard
Published: April 2020

Four hundred and twenty monomeric organoplatinum compounds, in which platinum atoms are five- and higher coordinated, are analyzed. The platinum atoms are found in the oxidation states +2, +3 and +4. The Pt(II) compounds by far prevail. There are wide varieties of the inner coordination spheres about the platinum centers. The Pt(II) compounds are five-coordinated (trigonal bipyramidal and square pyramidal), six-coordinated (different degrees of distortion), seven-coordinated (pentagonal bipyramidal, piano stool) and sandwiched (PtC10). The Pt(III) compound is square-planar. The Pt(IV) compounds are six- and eight-coordinated. There are several relationships between the Pt-L bond distances, covalent radii of the coordinated atom/ligand, and metallocycles, which are discussed. The trans-effect plays an important role in the inner coordination spheres about the Pt centers, especially on the Pt-L bond distances.

Published: April 2020

Introduction. Despite the significant progress in medicine, epilepsy is still a severe medical and social problem. It is the most common primary chronic neurological disease; it is of various aetiology, course and treatment, affecting people of all genders, age, race or social status.Aim. The article aims at verification of basic public’s knowledge about the disease of epilepsy and identification of the extent of capabilities of general and professional public in helping a patient with a major epileptic seizure.Material and Methods. Quantitative study using questionnaire and experiment. The study included a total of 200 respondents from general (GP) and professional non-medical public (CW).Results. 39% of GP respondents and 54% of CW respondents were capable of providing first aid. The most frequent mistake was forcing an object into the mouth in 17% of GP and 10% of CW. In the GP group, the level of skills significantly depends on respondents’ gender (p = 0.028), age (p = 0.012) and education (p = 0.003). Attainment of first aid course does not play a role in the level of knowledge and skills. In the CW group, significant results were found between evaluation of first aid provision and the age of respondents (p = 0.032) and provision of first aid and the category of health care workers (p = 0.014).Conclusions. Respondents’ basic knowledge and practical skills show signs of insufficiency. First aid courses need to be repeated regularly. (JNNN 2019;8(2):54–61)

Published: April 2020

The development of hard-to-recover reserves is now becoming a prerequisite for a successful oil business. Nevertheless, there is still no consensus on what reserves should be classified in this category and what benefits should be received by oil industry workers during their development. At the same time, it is the improvement of the tax system that can spur the development of new technologies for the extraction of “complex” oil and ensure the profitability of its production.
Musicalization of Literature: Kostas Ostrauskas’s The Quartet
Authors: Smolskaitė Giedrė
Published: April 2020

In works of literature, music can be found in the form of score fragments, notation symbols, song lyrics, musicological terminology, acoustic aspects of speech, musicians as characters, etc. Such manifestations connect two systems of signification and create an intermedial dialogue between music and literature, which requires a specific methodological approach. According to the intermediality theoretician Werner Wolf, “[t]he verbal text appears to be or become [...] similar to music, or to effects connected with certain compositions, and we get the impression of experiencing music ‘through’ the text”26. This paper discusses possible forms of a musico-literary relationship, the effects they produce, and examples of musicalization found in Kostas Ostrauskas’s play The Quartet (1969). In this play, the musico-literary dialogue is developed on different levels: structure and story, the twofold nature of the characters, intertextuality. Analysis of the play’s architextual relationship with the medium of music helps to identify the specific, musico-literary genre of this play. This unusual genre is defined not only by the content of The Quartet but also by its expression, i.e. graphic nuances, inserted imagery, etc. As shown by the analysis, the play could be understood as a metonymy of the history of both contemporary music and dramatic literature.
Critique sémiotique du populisme

Comment expliquer l’immense succès actuel de leaders populistes tels que Donald Trump, Jair Bolsonaro, Matteo Salvini, Victor Orban arba ir Marine Le Pen? Les explications sociologiques et politologiques font appel à une série de données contextuelles : ce qui joue en faveur des partis « anti-élitistes », c’est la crise économique, c’est le chômage, l’immigration, l’insécurité, attribués les uns et les autres à la faillite du « système » politique représentatif. Le but de cet article est de compléter ces explications en adoptant une perspective proprement sémiotique (en immanence) qui consiste à analyser les rapports sensibles, de caractère « intime » — personnellement, immédiatement, esthésiquement vécus — qui se nouent entre les leaders populistes et leurs partisans. L’article inclut en outre une typologie des régimes politiques (totalitarisme, absolutisme, démocratie représentative, démocratie « directe » et sa caricature, la démagogie) interdéfinis sur la base des régimes interactionels qui les sous-tendent.

Published: April 2020

Maize is the third most important food crop after wheat and rice. Maize is used as food for more than a billion people around the world and is used as animal feed, especially, poultry. The concentration of carotenoids, especially, β-carotene in maize grains, is very low. Therefore, the study of increasing the amount of provitamin A carotenoids including β-carotene is important. In maize, different alleles of crtRB1 and LcyE genes have a significant effect on β-carotene content. In this paper, we present the results of the study of allele polymorphism of these two genes related to the provitamin A carotenoid content in some traditional maize accessions collected from several regions in North and Central Highlands of Vietnam. The results showed that there were polymorphisms at the 3’ and 5’ ends of the crtRB1 and LcyE genes. Among 22 maize accessions, the proportion of favorable alleles at the 3’ end of crtRB1 gene was relatively high (5/22 = 22.73%). Similar results were obtained for alleles at 3’ end of the LcyE gene. Especially, there is an accession (Northern white gold maize) that carries favorable alleles at the 3’ ends of both crtRB1 and LcyE genes. While all investigated maize accessions did not carry favorable alleles at the 5’ end of both crtRB1 and LcyE genes. The identification of traditional maize accessions that carry favorable alleles for increasing b-carotene content opens up potential to exploit indigenous genetic resources for genetic research as well as to develop maize varieties with high β- carotene content.

Published: April 2020

Plant-parasitic nematodes are known as one of the most important pests attacking various plants in the world, and investigating the nematode component is very essential for management of this pest and prevent damage to plants in general. Our survey of plant-parasitic nematodes on medicinal plants in Melinh Station for Biodiversity, a place for conservation of precious plants and animals in Vietnam, identified ten species that belong to nine genera, five families, and two orders of plant-parasitic nematodes parasitizing six medicinal plants. Excoecaria cochinchinensis was parasitized by the highest number of nematode genera (5 genera, including Xiphinema, Discocriconemella, Meloidogyne, Helicotylenchus, and Hemicriconemoides), while Hymenocallis littoralis was associated with the highest number of plant-parasitic nematodes (2060 nematodes/250g soil). The results also showed that Discocriconemella limitanea was found to be a dominant species with the highest number of individuals on 6 medicinal plants, and the genus Helicotylenchus had the highest frequency of appearance (5/6 plants or 83.3%). These nematodes caused symptoms such as yellowing leaves, root galls, and root lesions, which directly affect the quality and yield of medicinal plants. Based on the results, this study showed that plant-parasitic nematodes are a potential threat to the cultivation of medicinal plants in Melinh Station for Biodiversity, and thus, control measures should be applied to ensure sustainable cultivation of medicinal plants in this place.

Published: April 2020

Huperzia serrata is a precious medicinal plant used in medicine to support and treat Alzheimer's disease. Currently, this species is in danger of extinction due to indiscriminate exploitation for commercial purposes. Furthermore, this species reproduces slowly and is difficult to cultivate artificially. The reproduction by spores of this species is very long and takes 15−20 years from the spore germination to mature plant, whereas asexual reproduction by tissue culture is also difficult. Therefore, cutting is an effective method to propagate this species on a large scale. In this study, we surveyed the factors affecting the survival rate, the rooting and the number of new leaves of the stem cuttings, including cutting length, growing substrate, and effects of growth-regulating hormones IBA (0 ppm, 500 ppm, 1000 ppm, 2000 ppm and 3000 ppm) and α-NAA (0 ppm, 10 ppm, 20 ppm, 30 ppm and 40 ppm). The experimental results showed that using cuttings of 6 cm in length treated with IBA at a concentration of 1000 ppm for 30 mins and cultured on the substrate mixture of soil, decomposed animal manure and rice husk at a ratio of 3:1:1 was the best for cuttings of H. serrata in Sa Pa. The results of this study will contribute to the conservation and development of genetic source of H. serrata in Vietnam.
Degradation of chlorobenzene and 2-chlorotoluene by immobilized bacteria strains Comamonas testosterone  kt5 and  Bacillus subtilis dkt
Authors: Duc Ha Danh , Oanh Nguyen Thi
Published: April 2020

Chlorobenzenes and chlorotoluenes have been used to produce a number of industrial products. They are toxic and widely detected in environments due to human contributory negligence. In this article, the mixed culture of a toluenes-degrading bacterial strain, Comamonas testosterone KT5 (a Gram-positive, catalase-positive bacterium) and a chlorobenzenes-degrading bacterial strain, Bacillus subtilis DKT (a Gram-negative soil bacterium) effectively degraded both chemical compounds co-contaminating in liquid media. In addition, the degradations of mixed compounds by biofilm, bacteria immobilized in polyurethane foam (PUF) and alginate were determined. The results showed that the degradation of both compounds by cells in alginate was significantly higher than that by suspended cells. Moreover, cells immobilized in these materials showed lower adverse effects than those of non-immobilized cells for long-term storage. For examples, the degradation rates for chlorobenzine and 2-chlorotoluene by resting cells reduced by 39.5% and 37.3% after storage for 4 months at 4°C, while the degradation rates by immobilized cells decreased by from 16.3% to 19.8% respectively.

Published: April 2020

The aim of this work was to reveal the interrelations between the number of T regulatory cells (Tregs) in patients with kidney cancer (KC) and phenotype of peripheral blood monocytes and their capacities to produce ROS. Patients with KC (T3N0M0, clear cell type) were examined prior to surgical treatment. Tregs phenotype and blood monocytes were identified by flow cytometry. ROS production of purified monocytes was carried out through the determination of lucigenin- and luminol-dependent spontaneous and zymosan-induced chemiluminescence activity. It has been found that the relative number of Tregs within total lymphocyte subset in KC patients was increased if compared to control values (in KC patients — Me = 6.3%). Then the patients were divided into two groups according to the median of Tregs number (less and more than 6.3%). The most pronounced changes in the phenotype of monocytes and their chemiluminescent activity were found in KC patients with the Tregs count of less than 6.3%. Our findings suggest that low frequency of Tregs in the periphery was associated with increased relative numbers of “intermediate” and “non-classical” (“pro-inflammatory”) monocytes as it was shown on the samples from patients with KC with a low level of Tregs. According to our data, both groups of KC patients had low levels of HLA-DR expression when comparing to control group. Furthermore, both groups of patients had decreased rates of HLA-DR and CD64 co-expressing cells. Changes in the phenotype of monocytes in patients with KC were closely linked with imbalance in ROS production. Thus, the monocytes spontaneous superoxide radical (primary ROS) synthesis in KC patients with a low Treg numbers were characterized by redused NADPH-oxidase activation time and increased level of its activity if compared to patients with a high Treg rates in peripheral blood. Next, the activation index for lucigenin-dependent chemiluminescence in KC patients was reduced, as well as it was independent of circulating Tregs rates and was determined apparently by the insufficiency of metabolic reserves. Similarly, spontaneous secondary ROS production by the monocytes in KC patients was lower then in healthy controls and was also independent of circulating Tregs rates. Finally, the induced secondary ROS synthesis and activation index for their synthesis in monocytes were reduced only in patients with KC with a low number of Tregs in the blood. In general, the characteristics of the chemiluminescent reaction of monocytes in patients with KC determined the imbalance in peripheral blood monocytes primary and secondary ROS production. Monocytes in patients with KC with a low number of Tregs in the blood were characterized by more pro-inflammatory activity due to the rapid activation and intensity of the synthesis of primary ROS.
Eosinophilic granulomatosis with polyangiitis in comorbidpatient: is the immunological diagnostics always unambiguous

Eosinophilic granulomatosis with polyangiitis (EGPA), previously called Churg—Strauss syndrome, represents a rare form of ANCA-associated necrotising vasculitis which affects small vessels. This disease is characterized by typical combination of immunological disturbances, hypereosinophilia, severe bronchial asthma, transient pulmonary infiltrates, and kidney injury which is less frequent than in other forms of necrotising vasculitis.

Verification of the diagnosis is often hampered by comorbidities, such as chronic obstructive pulmonary disease (COPD) in the patients with long-term smoking history and occupational hazards.

In this article, we report a clinical case of EGPA in elderly patient with preceding COPD which caused diagnostic difficulties for this eosinophilic syndrome. Clinical pattern at the beginning of disease was presented by moderate inspiratory dyspnea and cough with small amounts of mucus sputum, which appeared after longterm exposure to chlorine-containing substances. COPD diagnosis in this patient was based on clinical pattern, long smoking experience, and occupational hazards. However, persistence of the symptoms during the ongoing therapy, as well as multidirectional dynamics of transient pulmonary infiltrates found on repeated CT-scans, prompted us to intensify diagnostic search for a systemic disease. Clinical, laboratory and instrumental signs of bronchial asthma were revealed, as well as hypereosinophilia and sensory polyneuropathy, which, if combined with CT-scan data, allowed us to prove the EGPA diagnosis.

This case shows that, despite great value of immune diagnostics, with negative blood tests for ANCA, it is necessary to detect mutually complicating comorbid pathology. EGPA was considered the basic diagnosis, and COPD as accompanying disorder, taking into account such reasons as an unfavorable prognosis for EGPA and the need for long-term chemotherapy with systemic corticosteroids and monoclonal antibodies. ANCA-negative testing in the patient, absence of severe kidney and skin lesions allows to suggest better clinical prognosis in this patient.

Authors: Guo Yonghui , Zhang Xinyan , Zhao Liwei
Published: April 2020

To adapt to the characteristics of new energy long-distance transmission, this paper proposes a scheme of multi-fed voltage source converter grid connection and line-commutated converter transmission for a regional large energy base. First, the feasibility of this multi-infeed direct current (DC) transmission scheme is discussed. Then, the performance characteristics of the multi-infeed DC and other traditional transmission technologies are compared and analysed. In addition, the economic benefits of the multi-infeed DC project are evaluated. To study the characteristics of new energy multi-infeed DC power transmission mode, a long-distance energy transmission system based on multi-infeed DC power transmission mode is built using DIgSilent software. On the basis of the continuous power flow method, the static characteristics of the system are studied. Based on the time-domain simulation method, the transient characteristics of the system are studied. The results show that multi-infeed DC has great advantages in large-scale regional new energy long-distance transmission.
Swelling behaviour and microstructure of biochar bentonite
Authors: Kong Y. X. , Zhou A. N.
Published: April 2020

Biochar bentonite is a potential candidate as a porous layer for nuclear waste repositories. It would provide an ideal niche for bacteria that could feed on sulfate from the host rock and hydrogen from the corroding canisters. In this study, the influence of biochar amendment on the swelling properties of bentonite at different densities has been examined through swelling experiments. Scanning electron microscopy (SEM) images were used to study the surface microscopic morphology of biochar bentonite samples. On the basis of the SEM results, the fractal dimension representing the microstructure of biochar bentonite was determined. The relationship between fractal dimension and the maximum swelling pressure was discussed to reveal the correlation between the microstructure and the variation of mechanical properties for biochar bentonite.

Authors: YAVUZER Emre , KULEY BOĞA Esmeray
Published: April 2020

The antimicrobial activity of five hydrosols made from orange peel, pomegranate peel, shaddock peel, mandarin peel, and thyme plant was tested by microdilution and disc diffusion methods against 3 foodborne bacteria (Staphylococcus aureus, Salmonella Parathyphi A and Klebsiella pneumoniae) and 3 fish spoilage bacteria (Vibrio vulnificus, Pseudomonas luteola, and Photobacterium damselae). S. Parathyphi A was one of the most susceptible bacteria against all hydrosols tested mainly pomegranate, thyme and shaddock peel (with more than 10.5 mm inhibition zone). Inhibition zones on the growth of S. aureus were only observed from hydrosols of thyme and mandarin peel. Hydrosols made from orange and mandarin peel were effective on inhibition of the growth of fish spoilage bacteria. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of hydrosols were generally 50 and >50 mg/mL, respectively. These results show that thyme and pomegranate peel hydrosols had the strongest antimicrobial effects against test bacteria, although the effect of waste hydrosols vary depending on bacterial strains.
Москва – Воронеж. Сходство и различия в отношении студентов к науке и ученым
Authors: Винокурова Наталья Анатольевна , Гудович Ирина Семеновна
Published: April 2020

Цель : сравнительный анализ интереса к науке и ученым у студенческой молодежи двух городов – Москвы и Воронежа, выявление причин желания или нежелания работать в этой сфере и наличия уважения к науке, оценка различия потенциала притока молодежи в науку в этих городах. Обсуждение : статья базируется на материалах социологического опроса студентов в Воронеже и в Москве в 2017 году. Она является продолжением ряда работ, результаты которых были опубликованы авторами в 2018 и 2019 годах. Поскольку желание стать ученым связано с выбранной специальностью, для сравнительного анализа были сформированы группы студентов одной и той же специальности. Авторы работы полагают, что приток молодежи в науку будет в основном происходить в мегаполисах с авторитетными высшими учебными заведениями и с высоким потенциалом экономического развития. Предполагается также, что разница между мегаполисами как центрами науки может быть существенной. Поэтому в настоящем исследовании региональные различия в отношении студентов к науке и к ученым, в их желании (или нежелании) выбрать науку как сферу занятости исследуются на примере двух мегаполисов – Москвы и Воронежа. В работе проанализированы различия условий для развития науки в обоих городах. Результаты : исследование установило, что приоритетом для занятости молодежи обоих мегаполисов остается сфера управления и финансов. Однако различие между воронежскими и московскими студентами в отношении к науке и к перспективе научной карьеры существенно: москвичи и воронежские студенты представляют две разные группы молодежи. По шкале Маслоу москвичи имеют более высокий уровень потребностей. Их интерес к науке и желание работать в этой сфере выше, чем у воронежцев. Для воронежцев актуальнее материальные потребности, что объясняется более низким уровнем жизни. В то же время воронежцы в большей степени социально ориентированы: готовы работать на благо людей. Их можно назвать государственниками: они больше москвичей заинтересованы в развитии высоких технологий, новой техники для промышленности и новых видов вооружений.

Ideals Generated by Differential Equations
Authors: Kaptsov OlegV.
Published: April 2020

We propose a new algebraic approach to study compatibility of partial differential equations. The approach uses concepts from commutative algebra, algebraic geometry and Gr¨obner bases to clarify crucial notions concerning compatibility such as passivity and reducibility. One obtains sufficient condi- tions for a differential system to be passive and proves that such systems generate manifolds in the jet space. Some examples of constructions of passive systems associated with the sinh-Cordon equation are given
Teaching Motivation and Teaching Profession Attitude: The Case of Preservice Form Teachers
Authors: DERİNGÖL Yasemin
Published: April 2020

It
has been aimed in the present study to examined teaching motivations and teaching
profession attitudes of preservice classroom teachers. The research is a
quantitative study designed in survey model for comparing teaching motivations
and teaching profession attitudes of preservice classroom teachers. It has been
inferred from the study that teaching motivations and teaching profession
attitudes of preservice classroom teachers are positive and high; teaching
motivation does not differ by gender but teaching profession attitude differs
in favor of female preservice teachers; as the grade level increases, both
teaching motivation and teaching profession attitude increase and there is a
low positive relationship between teaching motivations and teaching profession
attitudes. The fact that preservice teachers can do more effectively the
requirements of the profession and become successful in their profession is
based on their positive attitudes towards the profession. These positive
attitudes shall direct their expectations from profession and increase their
teaching motivation. Within this scope, the present study has been carried out
by considering that it is important to determine teaching motivations and
teaching profession attitudes of preservice classroom teachers.
On some ways to achieve the absence of thermal stresses in an inhomogeneous through thickness infinite layer under stationary thermal loading
Authors: Kalynyak B. M.
Published: April 2020

A method for determining the characteristics of functional gradient materials (FGM) for providing zero thermal stresses in an infinite layer with given constant thermal loads is proposed. We assume that the classical convective conditions of heat transfer are given on the surfaces of the layer, the temperature field is stationary, the characteristics of the FGM are described by the model of a simple mixture, the characteristics of the thermo-stressed state and the material depend only on the transverse variable. Precise analytical expressions were obtained for the distribution of the concentration of one of the materials on the thickness of the layer in the absence of mass forces and heat sources, which provides zero longitudinal stresses.
L.O. Badalyan and current progress in the study of hereditary neuromuscular diseases
Authors: Zavadenko Nikolay N. , Vlodavets Dmitry V.
Published: April 2020

Hereditary neuromuscular diseases (HNMD) represent a large group of heterogenic morbid conditions, characterized by muscular weakness, muscular atrophies, disturbances of postural control and locomotor functions. Scientific research on HNMD, performed by academician L.O. Badalyan and his followers laid the background for solving many issues, regarding the diagnosis and treatment of these severe, progressive diseases. In many ways, academician L.O. Badalyan and his followers have anticipated the current understanding of pathogenic mechanisms of HNMD, which later were disclosed by means of modern molecular-genetic technologies. HNMD include progressive muscular dystrophies (PMD), spinal muscular atrophies (SMA), hereditary motor and sensory neuropathies, myopathic syndromes. The most prevalent progressive HNMDs are represented by dystrophinopathies (Duchenne PMD and Becker PMD) and limb girdle HNMD. The authors discuss experience and achievements in the studies of HNMDs and PMDs, conducted by academician L.O. Badalyan and his followers, as necessary prerequisites for the creation of modern approaches to genetic diagnostics of the diseases and forming their genetic registries, development of methods of etiopathogenetic therapy. Thanks to the accumulated experience and research there were discovered genes, which determine the HNMD development, pathogenic mechanisms of diseases with heterogenic clinical manifestations were studied. The data were accumulated for the formation of patients registries, determining groups for which a particular drug is being developed. The progress in genetic research has made it possible to identify more than 30 forms of limb-girdle PMD. A newly published classification of limb-girdle PMD is given, illustrating their genetic heterogeneity, the type of inheritance, the genetic locus of the mutation and defective protein are now taken into account. The article lists promising current global trends in the development of approaches to pathogenetic therapy of dystrophinopathies and limb-girdle PMD.

In the ’80s, Kuwait operations and the conflict between Iran and Iraq negatively affected the aquaculture and especially fish farming. This study was carried out to analyze fish productions and advancements in its development in the Northern Region of Iraq. Also, this study was aiming at obtaining the estimates of the production function for fish production and total income. The study involved 60 farms. Data were analyzed by using descriptive statistics, variance analysis and multiple regression. According to results, the benefit-cost ratio was 1.8, and it indicates that fish farming in the region was profitable. Results demonstrated that farmers’ age, educational status and fish farming experience, size and number of ponds, total fingerlings stocked, age of ponds, time of fish production, the weight of the sold-fish, fish mortality rate, and price of fish sale have statistically significant effects on fish production. According to the estimated production function, if all inputs are increased by 1%, then output increases by only 0.92%.
Vegetative Propagation of Peltophorum Petrocarpum (DC.) Backer ex K.Heyne a Multipurpose Tree
Authors: Ali Fadwa Mohammed Ahmed , Elbasheer Yahia Hamid Ali
Published: April 2020

This paper describes a successful protocol of vegetative propagation by using stem cuttings of mature Peltophorum petrocarpum plants. The experiment was conducted in the nursery of the Forestry Research Centre at Soba during November 2011and April 2012. The socioeconomic importance of P. petrocarpum comes from its multipurpose uses and there is a demand in production of its seed for tree planting and domestication activities. Hence there is a need for efficient and economically feasible propagation method of P. pterocarpum. Therefore the objective of study is to develop a vegetative propagation protocol by using rooted stem cuttings; and to determine the effects of the rooting hormone indole-3-butyric acid (IBA) on rooting potentiality of stem cuttings of mature mother plants. The result revealed a significant effect (p<0.001) of IBA concentrations on rooting percentage and growth performance of stem cuttings. The highest rooting percent was obtained with 200ppm IBA which was not significantly different from 100ppm, but significantly different from 50 and 0.0ppm. The effect of IBA concentrations on root lengths and of roots per cutting was significantly different from 0.0 and 50ppm treatments. Although 100ppm IBA gave the tallest root (4.6 cm) but it was not significantly different from 200ppm (4.3 cm). Survival of rooted cuttings after transplanting from the propagator was 100% and 97% with 100 and 200mg IBA respectively. Accordingly the conclusion reached is that rooted cuttings can be used successfully for obtaining health, uniform plantations of P. petrocarpum for large-scale, biomass production and tree planting programmes.
