Authors: Razali Noorshazlin , Hameed Sultan Mohamed Thariq , Jawaid Mohammad
Published: December 2020

The damage to composite structures caused by impact events is one of the most critical behaviors that inhibit the widespread application of composite material. As the application of synthetic and natural based composite material increases over time, improved knowledge of composite damage in areas such as automotive and aerospace is exceedingly necessary. It is important to study and understand the damage mechanism of composite structures to produce effective designs. The failure caused by damage in structural design can result in unintended consequences. Extensive research has been conducted to detect impact damage in synthetic fiber. There are various methods to identify and characterize the damage. This article provides a comprehensive review of recent literature focusing on the broader scope of impact damage and incipient thermal damage of synthetic and natural fiber-based composites. In this report, the available research is reviewed by considering all aspects related to damage in composite materials, particularly the work done on detecting and characterizing damage mechanisms of synthetic and natural fiber-based composites.
THE MIND-BODY PROBLEM(S) IN DESCARTES’ “MEDITATIONS” AND HUSSERL’S “CRISIS” (Part 2)
Authors: Leonov Andrii
Published: December 2020

The main topic of this paper is the mind-body problem. The author analyzes it in the context of Husserlian phenomenology. The key texts for the analysis and interpretation are Descartes’ magnum opus “Meditations on the First Philosophy” and Husserl’ last work “The Crisis of European Sciences and Transcendental Phenomenology”. The author claims that already in Descartes’ text instead of one mind-body problem, one can find two: the ontological mind-body problem (mind-brain relation) and conceptual one (“mind” and “body” as concepts). In Descartes’ “Meditations”, the ontological level is explicit, while the conceptual level is implicit. In Husserl’s “Crisis”, on the other hand, the situation is different: the conceptual level of the problem (as the opposition between transcendental phenomenology and natural sciences) is explicit, while the ontological level is implicit. Nevertheless, it seems that Husserl has answers to both the “traditional” as well as the “conceptual” mind-body problems.

Published: December 2020

A new structure for the diagram of measurements synchronization using GPS modules for two or more spaced stations is proposed. To simplify the modeling, a set of sources of GPS clock signals is replaced with a virtual reference generator with certain phase instability. The stochastic model is developed for synchronization of multiple devices. The cumulant and stochastic differential equations for the synchronization model are solved. The performed computation experiments made it possible to identify the model parameters, including loop gain, and factors of conversion and inertia of the loop. Implementation of the results into the structure of broadband magnetotelluric station LEMI-423 significantly reduced a measurement error produced by clock signal instability.

The problem of the automated determination of the parameters of the sporadic decameter radio emission of the Sun with help of the radio-telescope URAN-3 taking into account its functions in the Ukrainian VLBI URAN structure is analyzed. An overview of alternative solutions of the problem is carried out. The technology of searching and detecting the radio bursts of type II and determination of such parameters as speed of drift in frequency sub bands, intensity, and duration and frequency width of bursts for a number of selected frequencies are considered. The effectiveness of the developed technology is confirmed by the results of long-term radioastronomical observations carried out at the URAN-3 radio telescope in 2011–2017. The formed on the basis of obtained and accumulated experimental data multiparameter relative database of solar activity is intended for further studies of the relation between the helio- and the geophysical phenomena for the purpose of developing forecasting models of geophysical manifestations of solar activity and evaluating the “geoefficiency” of active solar processes.
A new method of fluxgate signal extraction
Authors:   Lviv Centre of the Institute of Space Research NAS and SSA of Ukraine, Marusenkov A.A.
Published: December 2020

Using dedicated high-frequency measuring system the distribution of the Barkhausen jumps intensity along a reversal magnetization cycle was investigated for low noise fluxgate sensors of various core shapes. It is shown that Barkhausen (reversal magnetization) noise intensity is strongly inhomogeneous during an excitation cycle. In the traditional second harmonic fluxgate magnetometers the signals are extracted in the frequency domain, as a result, some average value of reversal magnetization noises is contributed to the output signals. In order to fit better the noise shape and minimize its transfer to the magnetometer output the new approach for demodulating signals of these sensors is proposed. The new demodulating method is based on information extraction in the time domain taking into account the statistical properties of cyclic reversal magnetization noises. This approach yields considerable reduction of the fluxgate magnetometer noise in comparison with demodulation of the signal filtered at the second harmonic of the excitation frequency.
The effectiveness of compatible agrophytocenoses depending on the allelopathic interaction of plants
Authors: Semenchenko H.I. , Melnyk A.V. , Zavertalyuk V.F.
Published: December 2020

The main criteria for the functioning of agronomic phytocoenosis are indicators of their economic and energy efficiency. In particular, the issues of manufacturability and rational use of sown areas during the growing season characterize the level of agronomic culture in a particular geographical area. Under these conditions, it is important to study the possibility of joint cultivation of agricultural plants, which will reduce energy consumption, improve the phytosanitary condition of crops and increase the profitability of agricultural production. When growing tomatoes in compatible crops, it is necessary to take into account not only aspects of technology, but also the interaction of plants with each other at the level of physiological and biochemical processes. That is why allelopathic relationship between plants, due to the physiologically active substances they secrete at the initial stage of ontogenesis, is not without the interest. It is the scientific basis for the development of sound crop rotation and mixed (compacted) crops, and also helps to increase the productivity of agro- and natural coenoses in order to prevent soil fatigue in monoculture, control weeds, pests, phytopathogenic organisms, etc. Allelopathic substances (collins) of some plant species cause different reactions to other species: some of them have active growth, others have suppressed growth processes, and still others remain neutral to such effects. The stimulating effect is manifested in the awakening of seeds, strengthening of growth processes and the formation of seedling organs. In future this fact will lead to the activation of plant development and an increase in their productivity. At the same time, mutual oppression of plants cannot be ruled out, which can be detected during laboratory studies using biological tests. Field studies of compatible (compacted) crops of tomato with other plants (sugar corn, shallots) were performed using allelopathic testing methods according to Grodzinsky. The expediency and economic efficiency of growing tomatoes in compatible crops with shallots on a green feather have been experimentally proved using statistical methods.

Published: December 2020

This study aimed to evaluate the physicochemical properties of water, to determine the macro-benthic invertebrates of this ecosystem. The money samples of water are taken (November - May) at three stations at different depths, including a very polluted one at downstream of the Wadi. Several physico-chemical parameters were measured (pH, electrical conductivity, turbidity, BOD5 MES, water temperature and salinity). The Bi-monthly sampling of macro invertebrates revealed the existence of 40 taxa, divided into 4 branches (amphibians, molluscs, arthropods, annelids), made up of 2344 identified individuals, and distributed according to the bathymetry, where the majority are Arthropods with 95.38%. The annelids represent 3.71%, collected mainly at the level of the strongly anthropized site C. Therefore, the distribution of the macrobenthic fauna, depends on the physico-chemical parameters, on the geographical position.Maintaining a standard water quality in this aquatic ecosystem requires continuous monitoring of its physicochemical characteristics.

Published: December 2020

The deep-water rose shrimp, Parapenaeus longirostris (Lucas, 1846) is one of the Decapod crustacean species that is targeted by coastal and deep-sea demersal fisheries in the western Mediterranean, in the Algerian west coast in particular. Despite its socio-economic importance and commercial interest across the country, there were only few studies focusing on its biology and ecology and no species development plan has been drawn up for now. Our study of the rose shrimp diet was based on the analysis of the faunistic composition of the ingested prey. Seasonal sampling was carried out at Beni Saf port (western Algeria) during 2018-2019, from landings from inshore trawling fisheries. A total of 641 individuals were analyzed, while taking account of males and females and size classes. Results of stomach content analyzes showed a wide range of benthic and endobenthic species. Crustacea are the preferred prey (F=77.69%), followed by Foraminifera, Annelida Polychaeta, and Mollusca with respective frequencies of (77.22%, 58.50% and 52.73%). Radiolaria, Porifera and Echinodermata represent a less important part in the diet of this species and constitute accidental prey, whose frequency is less than 10%. Benthic organisms with silt ingest the plant and various debris, which are the secondary prey with an average frequency of 14.81%.

In the industrial pig farm for 26 thousand heads, the analysis of the influence of a forage factor on bacteria carriers of a uterine pig population in connection with mass morbidity of dairy piglets on anaerobic enterotoxemia is carried out. Actinobacillus pleuropneumonia, Pasteurella multocida, Clostridium perfringens, Neisseria spp., Candida albicans, Aspergillus niger which are able to form biofilms, were isolated from five samples of “SK-1” compound feed for pregnant sows and from the blood of animals (n=20) fed with this compound feed. The structural basis of the most stable biofilms in vitro were the aerobic fungi Aspergillus niger and Candida albicans. Biofilm-forming variants of these bacteria showed multidrug resistance to 30 antimicrobial drugs (synthetic penicillins, cephalosporins, fluoroquinolones, aminoglycosides, tetracyclines, combination drugs). Isolates of associative microflora isolated from the blood of sows were pathogenic for 30% of laboratory mice. It was found that probiotic agent No1 (composition based on Bischofite with probiotics) showed the universal bactericidal activity against the bacteria Actinobacillus pleuropneumonia, Pasteurella multocida, Clostridium perfringens, Neisseria spp.

Published: December 2020

Current Status of Saussurea heteromalla was investigated in Galiyat areas of District Abbottabad, viz., Jahaffar, Seri, Beeran Gali, Banj, Haryala, Daryala Gali, Sarbhanna, Barriyan, Akhreela and Broangiala. Saussurea heteromalla was found common in Seri, Sarbhanna and Barriyan; endangered in Haryala, Jahaffar, Banj, Daryala Gali and Beeran Gali and absent in Akhreela and Broangiala. In vitro regeneration of Saussurea heteromalla (D. Don.) Hand-Mazz on MS media was conducted and shoots were developed on full strength MS medium supplemented with 1 mgL-1 GA3. The developed shoots were transferred for root induction to half strength MS medium fortified with various concentrations of Indole butyric acid (IBA) and α-Naphthalene acetic acid (NAA) i.e. T1 (control), T2 (2 mgL-1 IBA), T3 (3 mgL-1 IBA), T4 (4 mgL-1 IBA), T5 (1 mgL-1 NAA), T6 (2 mgL-1 NAA) and T7 (3 mgL-1 NAA). Maximum mean shoot length (6.3 cm), mean number of leaves (7), mean number of nodes (5.25); highest root emergence percentage (71%), means root length (1.5 cm), mean number of roots (3) and highest survival rate (100%) was recorded in treatment T4. However, treatments T5 and T6 also seem to be effective for in vitro rooting of Saussurea heteromalla. Treatments T2, T3 and T7 showed minimum root growth. It was concluded that IBA at higher concentration is more effective for in vitro rooting and better shoot growth of Saussurea heteromalla whereas NAA also initiate rooting but at lower concentration.

Published: December 2020

Monotheca buxifolia is an ethnomedicinally and economically important threatened fruit bearing plant species in Malakand Division Pakistan. The genetic diversity among the 92 various genotypes of Monotheca buxifolia was carried out using sodium dodecyl sulfate poly acrylamide gel electrophoresis (SDS-PAGE) method. A considerable amount of inter districts genetic diversity (66.70%) was observed among the genotypes of M. buxifolia. Protein profiling was conducted on 12% gel electrophoresis. A total of 6 protein bands were observed in M. buxifolia genotypes. SDS-PAGE practice is a convenient scheme for the examination of both genetic diversity and relationship. Particularly, L-4 and L-5 were monomorphic in the inter districts Monotheca buxifolia genotypes and was recognized as species specific. The remaining other loci were polymorphic. In this investigation, the high inter and intra- districts specific diversity was observed demonstrating SDS-PAGE is an authoritative procedure for categorizing the genetically diverse germplasms in M. buxifolia. The findings from this study could be useful in the identification and selection of suitable M. buxifolia genotypes for future conservation programmes. Today, there is still a need to examine the genetic diversity and protect genetic resources, in particular wild species, for possible benefits in plant conservation programmes. To the best of our knowledge, this is the first ever report that addresses genetic variability in M. buxifolia.

Authors: Gavrilina O.G. , Perotskaya L.V. , Alekseeva N.V.
Published: December 2020

The dynamics of mass and linear parameters of lymph nodes of ducks is a direct reflection of structural and functional transformations of their lymphatic parenchyma. The peculiarities of quantitative dynamics of tissue components of peripheral lymphatic organs at early stages of postnatal ontogenesis are to a great extent determined by advanced growth rates of their absolute mass against the background of sharp increase of their antigenic stimulation intensity. Parenchyma of lymph nodes of newborn ducklings is characterized by relatively low degree of differentiation and is represented by diffuse lymphatic tissue with no pronounced signs of its division into separate functional zones. Internally, the lymphatic channel is represented by only two lymphatic sinuses - the central one, which is located in the central part of the organ and occupies a large relative area and a discrete edge sinus, which borders on the node capsule and has a much smaller relative area and, accordingly, is located at its periphery. The organ parenchyma is a diffuse cluster of stromal and lymphatic cells in the enlarged lymphatic vessel between the central (inner) and edge (outer) lymphatic sinuses, without signs of its division into cortical and brain matter. Among the lymphatic tissue of the lymph node, reticular stroma cells and the population of small lymphocytes have the largest relative amount.

Objetivo Describir la distribución geográfica y el rol de factores sociodemográficos sobre la mortalidad por suicidios, de acuerdo con sexo y grupos de edad en Argentina durante los períodos 1999-2003 y 2008-2012.Método El rol de factores sociodemográficos sobre la mortalidad por suicidios y su distribución geográfica fueron analizados mediante regresiones múltiples espaciales. Se incluyeron tres variables independientes: un índice de fragmentación social, un índice de pobreza y la densidad poblacional como indicador del nivel de ruralidad.Resultados La fragmentación social y el suicidio estuvieron directamente relacionados en hombres de 10-59 años y mujeres de 10-29 años durante 1999-2003. Durante 2008-2012 el riesgo de suicidio fue mayor en áreas de baja densidad poblacional, salvo en mujeres de 10-29 años.Conclusiones Los resultados obtenidos en este estudio apoyan la hipótesis de fragmentación social como fenómeno asociado al riesgo de suicidio en departamentos de la Argentina, pero también dan apoyo a la hipótesis de un mayor riesgo de suicidio en áreas rurales. Las medidas de prevención del suicidio podrían enfocarse en políticas que promuevan la integración social, especialmente en población joven, así como también una mayor integración de las áreas rurales con el resto del territorio.
Subculturas musicales y cultura popular urbana costarricense en los documentales Vargas Brothers y Se prohíbe bailar “suin”
Authors: Cuvardic García Dorde , Cordero Cantillo Eduardo , Chaves Jaén Christian
Published: December 2020

La música popular ha ocupado un lugar relevante en la historia del documental. Un grupo numeroso de documentales se ha dedicado a la trayectoria profesional y privada de los músicos, figuras que encaran el desgaste de las giras, de las drogas, etc., mientras que otro grupo enfoca su atención en las prácticas de consumo de la música popular (aficionados, fans). El documental costarricense ofrece manifestaciones de ambas vertientes, en el marco de la modernidad centroamericana: la redención de un grupo de rock and roll, después del viaje a los infiernos de las drogas y el alcohol, en Los Vargas Brothers, y el consumo (baile) de un género considerado marginal por mucho tiempo, el swing criollo, en Se prohíbe bailar suin. La cultura popular urbana costarricense queda representada en ambos documentales.

Se estudió la fenología de Wercklea insignis, árbol con potencial importante por sus flores conspicuas, que crece a orilla de los ríos, en la Reserva Biológica Alberto Manuel Brenes, Alajuela, Costa Rica. La evaluación se realizó de junio de 2014 hasta octubre de 2015.  Se monitorearon 10 individuos con producción de flores, con un diámetro a la altura del pecho de 7 cm a 11.9 cm, mientras que la altura de los árboles osciló entre 8 m y 15 m. Cada espécimen de W. insignis se enumeró con marcas plásticas, luego se georreferenciaron cada uno de ellos. Las fenofases de floración (subanual), brotes foliares, caída de follaje fueron continuas, sin perder las hojas completamente. En tanto que la fructificación estuvo ausente solo en octubre 2014 y junio 2015. Existió asincronía entre individuos en el comportamiento de las etapas fenológicas. La caída de follaje (n=10, r= 0.35, p<0.05) y el nacimiento de flores (n=10, r= 0.46, p<0.05) se correlacionaron con la precipitación; mientras que el brote de frutos (n=10, r= -0.51, p<0.05) tuvo un vínculo inversamente proporcional con este fenómeno.

Most recent studies show the impact of violations in the metabolism of folate and metin period in the pathogenesis of neural tube defects (NTD) of the fetus. Metafolin has a number of advantages, which primarily includes direct intake of substances in biologically active form and the optimum effect, even in the case when the patient homozygote and/or heterozygote genotype 677С T polymorphism in MTHFR. With the aim of prevention and treatment of various pathological conditions related to folate deficiency during pregnancy, it is advisable to apply vitamin-mineral complexes, containing metafolin - active form of folate with high bioavailability. Key words: MTHFR, metafolin, folic acid, pregnancy.

Published: December 2020

The objective: studying of features of the psychoemotional and vegetative status at women with placental dysfunction at the previous pregnancy. Patients and methods. Complex clinical-laboratory examination of 89 women, from which was conducted: control group – 42 obstetrically and somatically healthy multipara, delivery through natural patrimonial ways; І group – 47 women with placental dysfunction at the previous pregnancy. Carried out a cardiointervalografia by means of a single-channel electrocardiograph and used a scale questionnaire of a condition of the pregnant woman. Results. It is established that regulation of cardiac rhythm at women at the previous pregnancy happens to placental dysfunction in the conditions of an autonomous contour which controls normal work of heart and vegetative nervous system. Further, there is an expressed strain of regulatory mechanisms that is shown by centralization of management of cardiac activity and sharp rising of activity of sympathetic nervous system. At the final stage influence of the central contour considerably decreases and patofunctionale vegetative equilibrium is again formed. Conclusions. The received results need to be considered when developing tactics of conducting pregnancy at these women. Key words: placental dysfunction, vegetative and psychological status.

Authors:   Bukovinian State Medical University, Chernivtsi, Ukraine, Kravchenko E.V.
Published: December 2020

In women with miscarriage in early pregnancy by ultrasound was studied the volume of the ovum, the volume of the cavity of the amnion and their relationship. Using special three-dimensional VOCAL program performed the calculation of the volume of the chorion, the evaluation of his vascular system based on the definition of the vascularization index (VI) and flow index (FI). The aim of the study: to study the stages of growth and vascularization of the chorion with the threat of miscarriage in the first trimester of gestation. Materials and methods. There were examined 50 pregnant women with threat of miscarriage at early terms of gestation: 30 - burdened obstetric history (BOH), receiving the drug micronized progesterone 50 mg 3-4 times per day (the main group) and 20 pregnant women, the history of which was not encumbered, who were on symptomatic therapy (control group). Results. Analysis of the frequency of occurrence of extragenital pathology in the study groups showed that in women with recurrent pregnancy loss and BOH somatic diseases were almost 2 times more often than in the control group (respectively 60% and 30%). The frequency of infectious complications in the first trimester of pregnancy in women with threatened abortion and BOH compared to the control group of patients, significantly more frequently noted violations of vaginal microbiocenosis, in the form of gardnerellosis (20% and 10%), Candida vaginitis (30% and 5.5%) and urogenital infections – chlamydia, ureaplasmosis, mycoplasmosis (15% and 0%). All pregnant women was carried out sanitation of the source of infection in the first trimester of gestation – local therapy, systemic treatment after completion of the processes of placentation. Conclusion. The study found that use of micronized progesterone in miscarriage in the first trimester of gestation contributes to the growth of the volume of the chorion, the intensity of the flow in the parenchyma and a complete restructuring of the spiral arteries resulting in inadequate formation of the placental-uterine blood flow, which certainly improves the prediction of the further course of pregnancy. Key words: miscarriage, the I trimester of gestation, the vessels of the chorion.
Finite element modeling of fluid flow in fractured porous media using unified approach

Published: December 2020

Understanding fluid flow in fractured porous media is of great importance in the fields of civil engineering in general or in soil science particular. This study is devoted to the development and validation of a numerical tool based on the use of the finite element method. To this aim, the problem of fluid flow in fractured porous media is considered as a problem of coupling free fluid and fluid flow in porous media or coupling of the Stokes and Darcy equations. The strong formulation of the problem is constructed, highlighting the condition at the free surface between the Stokes and Darcy regions, following by the variational formulation and numerical integration using the finite element method. Besides, the analytical solutions of the problem are constructed and compared with the numerical solutions given by the finite element approach. Both local properties and macroscopic responses of the two solutions are in excellent agreement, on condition that the porous media are sufficiently discretized by a certain level of finesse. The developed finite element tool of this study could pave the way to investigate many interesting flow problems in the field of soil science.

In this paper, we present detail data of Pliocene - present tectonics and strain rate from GPS measurement and seismic interpretation. Using international reference frame ITRF08, we revealed absolute tectonic velocities of GPS sites with the slip rate to the east between 22 to 25 mm/year, to the south between 4 to 8 mm/year. The present strain rate was determined from present tectonic velocities that were consistent with the recent strain rates determined from seismic profiles, thickness of Pliocene - Quaternary sediments. Present day strain rate varying from 10 to 30 nano per year indicated that the region has been deformed weakly, in a stable tectonic regime.
An extension of Lucas identity via Pascal's triangle
Authors: ANATRIELLO Giuseppina , VİNCENZİ Giovanni
Published: December 2020

The Fibonacci sequence can be obtained by drawing diagonals in a Pascal’s triangle, and from this, we can obtain the Lucas identity. An investigation on the behavior of certain kinds of other diagonals inside a Pascal’s triangle identifies a new family of recursive sequences: the $k$-Padovan sequences. This family both contains the Fibonacci and the Padovan sequences. A general binomial identity for $k$-Padovan sequences which extends both the well-known Lucas identity and the less known Padovan identity is derived.
