In the second half of the 20th century, post-war Europe saw major economic growth due to national reconstructions associated with high employment, industrial mass production and demographic boom. As a consequence, generalised globalisation raised an intensified international flux of goods, services and information. Advancing technology and ever-increasing worldwide goods consumption has led to the age of plastics. Their relatively easy processability and strong physico-chemical properties such as optical, mechanical or barrier properties make them the perfect candidate for many applications in building and construction, automotive, agriculture, electronics, household leisure and sports, appliances, medical furniture and packaging. In 2018, the production of plastic in Europe reached 64.4 million tons and the packaging sector represents the largest sector demands1. The market value of the packaging sector was valued at high as 917 billion US dollar in 2019 and is still rising at an annual growth of 2.8%2.In the packaging industry, the largest part concerns food packaging3 and the overall increasing number and movement of food products however also causes an increasing amount of worldwide food waste. Around one third of the globally produced food is wasted according to the estimations of the Food and Agriculture Organization (FAO) of the United Nations4. This represents 1.2 billion tons per year which seems outrageous as the FAO also estimated in 2018 that around 800 million people were chronically undernourished in the world. Food waste is a important challenge for mankind as the world population is expected to reach 10 billion people in 2050 and feeding all of them is a great challenge.

“Green” synthesis of silver nanoparticles (AgNPs) by a galvanic replacement (GR) on magnesium in solutions of sodium polyacrylate (NaPA) under ultrasound (42 kHz) is reported. The mechanism of combined action of GR and ultrasound on the formation of nanoparticles is proposed. Synthesized solutions of AgNPs are characterized by an absorption maximum at 410 nm, the value of which does not depend on the concentrations of precursors (AgNO3 and NaPA) and the duration of the process. The dimensions of nanoparticles that have a spherical shape do not exceed 30 nm. With increasing concentration of surfactant, there is a tendency to decrease in size. The rate of synthesis of AgNPs increases almost in proportion to the concentration of AgNO3 in the solution, while the effect of NaPA concentration is negligible. The synthesized nanoparticles efficiently demonstrated a bactericide effect on Escherichia coli and Staphylococcus aureus.

In the present work we have explored a new catalyst prepared with Algerian clay and a new method to synthesise polystyrene and poly(1,3-dioxolane). This technique consists of using Algerian modified clay (Kaolinite-H+) as a green catalyst. Kaolinite-H+ is a proton exchanged clay which is prepared through a simple exchange process. Synthesis experiments are performed in bulk. The polymerization of styrene in bulk leads to the yield of 83 % at room temperature with the reaction time of 3 h. Molecular weight of the obtained polystyrene is calculated by 1H NMR and is about 2196 g/mol. Polymerization of (1,3-dioxolane) is carried out at room temperature with the reaction time of 3 h and polymerization yield of 91 %. The calculated molecular weight of the obtained poly(1,3-dioxolane) is about 573 g/mol. The structure of the obtained polymers is confirmed by FT-IR and 1H NMR. The modified clay (Kaolinite-H+) is characterized by FT-IR, XRD and SEM analysis.

Published: November 2021

The current study deals with the removal of cationic dye (brilliant green) and anionic dye (methyl orange) from wastewater by using sunflower husk as an adsorbent. The operation takes place batch wise by applying several concentrations of the dye solution with various adsorbent amounts, at a range of initial PH values and particle sizes at varying contact time intervals. The percent of dye removed for two dyes increased with increasing time and adsorbent dose and decreased with increasing the dye concentration and particle size. The equilibrium time differed according to conditions used. The optimum removal for brilliant green dye was 98 %, which was achieved at 50 ppm dye concentration, 2 g\l adsorbent dose, 75 µm particles size and pH 7 at contact time of 1 h, compared with low removal for methyl orange that reached 54 % under optimum conditions (dye concentration 10 ppm, adsorbent dose 4 g/l, pH 3 at the same particles size and time). Kinetic studies were conducted and revealed that the adsorption was well defined by pseudo-second order model and could be described by the Langmuir isotherm.

Published: November 2021

The paper considers water purification processes from Bacillus bacteria type under the conditions of gases bubbling only (argon, helium, oxygen, and carbon dioxide), cavitation and combined action of gas and cavitation. The synergistic effect was found under conditions of simultaneous action of gas and cavitation (kd(gas/US ) >kd(gas) + kd(US) almost double) and it was shown that kd(gas/US) >kd(gas) by almost an order of magnitude. Relative series of effective destruction of microbial cells was established: Ar/US > О2/US >Не/US > СО2/US. Destruction degree of the cells reaches 70 %at the short-term Ar/US exposure (~8 min), which is 7 times more active than cavitation action and 13.5 times more than bubbling of Aralone.

Authors:   Lviv Polytechnic National University, Druzhynin Anatoliy
Published: November 2021

The ohmic contacts to the n-type conductivity gallium antimonide whiskers were created due to a current pulse shaper. It was established that I–V characteristics of GaSb whiskers at low temperatures are linear, regardless of the direction of current transmission. That allows using the investigated techniques to create electrical contacts and study their electrophysical characteristics. GaSb samples with a diameter of 12 μm and 20 μm were studied at temperatures 4.2 K and 77 K. A slide table with bath and microfurnace was made for welding ohmic contacts to GaSb whiskers. Gold microwire with a diameter of 30 μm was used as a contact material. The melting was carried out under the flux layer. It was revealed that the fusion is one of the most suitable methods for creating contacts to the whiskers grown by gas transport reactions.

Voltage and current are sharply variable random (stochastic) processes in traction networks of DC electric transport systems. As a result, electronic and hybrid electricity meters used in electric systems measure electric power with a large relative error that significantly exceeds that of their accuracy class. In this paper the principle of developing smart meters for accounting the electricity transmitted from traction substations to electric rolling stock through a traction network is proposed. Proposed ideas are developed on the basis of the random processes correlation theory. The meter operates in real time and monitors not a set of realizations of random voltage and current processes, but their deterministic characteristics, that is, time functions of mathematical expectations and variances which make up the background of its operating principle. The experimental implementation of the proposed principle has been conducted in the feeder zone of an A-B section of the GisDnieper Railway of Ukraine, where registration and processing of realizations of stochastic voltage and current processes obtained in real operation mode has been done. The ratios obtained for active and reactive power can be applied not only for traction power grids, but also for electric networks of external power supply of DC electric traction systems as the basis for the “smart meter” design.

Published: November 2021

he differential equations of motion of electrically charged bodies in an uneven vortex electric field at all possible range of velocities are obtained in the article. In the force interaction, in addition to the two components – the Coulomb and Lorentz forces – the third component of a hitherto unknown force is involved. This component turned out to play a crucial role in the dynamics of movement. The equations are written in the usual 3D Euclidean space and physical time.This takes into account the finite speed of electric field propagation and the law of electric charge conservation. On this basis, the trajectory of the electron in an uneven electric field generated by a positively charged spherical body is simulated. The equations of motion are written in vector and coordinate forms. A physical interpretation of the obtained mathematical results is given. Examples of simulations are given.

Authors: A. I. Prodanchuk
Published: November 2021

A comprehensive study of anatomical-functional peculiarities of the cranial bones promotes implementation of new methods of performing radical and reconstructive-restorative surgery on the face and cranium. Objective: to determine peculiarities of formation of the hard palate folds structure in the fetal and early neonatal periods of human ontogenesis. Materials and methods. The study was conducted on 53 specimens of dead fetuses from 4 to 10 months of development and on 9 specimens of dead neonates by means of macro- and micro-section, preparing histological and topographic-anatomical sections, and morphometry. Formation of the hard palate folds during the second and third trimesters of the intrauterine development was found to consist of the following stages:  epithelial thickening, penetration into the adjacent mesenchyme originating the rudiment of the fold; smoothing of the basal membrane and epithelial outgrowth over the surface with formation of the primary fold; condensation of mesenchyme cells under the fold apex; formation of fibrous stroma inside of the fold which is a peculiar core; epithelial smoothing to even thickness similar to that one embracing the areas between folds with formation of the final fold. At the end of the third trimester of the intrauterine development posterior transverse palatine folds become less marked, some of them disappear, and the anterior ones become more marked, closer and pressed one to another.
PECULIARITIES OF THE FUNCTIONAL STATE OF THE MOTHER-PLACENTA–FETUS SYSTEM IN PREGNANT WOMEN WITH PLACENTAL DYSFUNCTION
Authors: L. M. Yuryeva
Published: November 2021

Among the causes that lead to antenatal affliction of the fetus, namely its hypoxia, hypotrophy, ante- and intranatal distress, is placental dysfunction (PD). Perinatal mortality in PDs is 10.3‰ in newborn infants, 49 ‰ – in preterm infants. Perinatal morbidity with PD reaches 70‰, and mortality rate – 20%. Objective. To investigate the functional state of the fetoplacental complex (FPС) in pregnant women with PD. Material and methods. The functional status of the FPC in 104 patients with PD (main group) and in 136 women with uncomplicated pregnancy and delivery (control group) using ultrasound placentalography, Dopplerometry was examined. Research results. The ultrasound characteristics of the placental dysfunction were the following: discrepancy between the degree of maturity of the placenta of the gestation period, true thickening of the placenta, its hypoplasia, reduction of echogenicity of the placenta, oligohydramnios. Dopplerometric signs of disorder of the utero-placental blood flow were high peripheral vascular resistance, both in dominant and in subdominant UA, asymmetry of blood flow in UA. Hemodynamics of fetal-placental circulation against the ground of PD was characterized by a decrease in the final diastolic blood flow velocity, which was manifested by an increase resistance in the peripheral vascular of the fetal part of the placenta,  decrease in placental coefficient. The peculiarity of fetal blood flow in pregnant women with PD was the decrease in the mean value of vascular resistance indices in the middle cerebral artery of the fetus and a significant decrease in the cerebral-umbilical index. Conclusions. In pregnant women with placental dysfunction hemodynamic changes in the utero-placental complex are associated with decrease in the intensity of placental-fetal blood flow and in 16.3% of cases by centralization of the fetal circulation. Timely Dopplerometry is important both in the diagnosis of the compensatory capabilities of the FPK, and during determination of reasonable suggested obstetrical tactics.

Published: November 2021

An important condition to understand etiopathogenesis of gynecological diseases is improvement of examination of fetal morphogenesis concerning the urinary system and other organs. For example, chronic pelvic ache can result from a wide range of disorders: endometriosis, myoma, commissures, cystitis, colitis, pathology of the femoral joint and diseases of the pelvic bones. Meanwhile the majority of these diseases can be diagnosed, prevented or treated during antenatal period. 50 specimens of human fetuses were examined by means of a complex of morphological methods in order to study morphogenesis of the internal female reproductive organs at the beginning of the uterine period. The article deals with the features of the development of paramesonephric ducts and their derivatives at the beginning of the fetal period of human ontogenesis. At the beginning of the fetal period the position and shape of the fallopian tubes are found to be caused by close correlations with the adjacent organs and structures. From three to six narrow portions are formed along the uterine tube. The morphometric parameters of the ampulla of the fallopian tubes vary depending on the age of the fetus.

Light information that is perceived by the retinal photoreceptors is transmitted along the retinohypothalamic pathway (the retinal ganglion cells present in it) and supraoptic fibers, suprachiasmatic, paraventricular, arcuate nuclei of the hypothalamus, through the trunk of the upper thoracic region and lateral intermedial nuclei of the spinal cord, sym- pathic neurons of the superior cervical ganglion in the pineal gland. In the dark, signals from the suprachiasmatic nucleus enhance the synthesis and release of norepinephrine from sympathetic endings. The experiments were carried out on 40 sexually mature male outbred white rats weighing 0.15-0.18 kg. The animals were kept in cages at a constant temperature, air humidity and free access to water and food. Experimental animals were divided into two series, in each of which the biomaterial was taken at 14.00 and 02.00 h. The selected timing of the experiment is due to the different functional activity of the pineal gland in the indicated time periods of the day. Submicroscopic studies of the supraoptic nuclei of the hypothalamus of intact animals at 14:00 showed that the majority of neurosecretory cells are round-oval in shape with rare invaginations and nuclei of irregular shape with shallow invaginations of the karyolem. The karyoplasm contains lumps of chromatin and a dense osmiophilic nucleolus. Neuroplasm occupies a small volume, in it the tubules of the granular endoplasmic reticulum are tightly packed with a small lumen, where there are many ribosomes and polysomes, as well as a small amount of evenly distributed granules. In the Golgi complex, secretory granules of different sizes are formed. Mitochondria, small with a dense matrix, contain few cristae. Some of them are in an energetically stressed state, are able to hypertrophy and partially lose their cristae or die. The ultramicroscopic organization of neurosecretory cells of the supraoptic nuclei of the anterior hypothalamus of rats was investigated. Under the standard illumination mode (12.00C: 12.00T), the ultrastructure of neurons indicates a decrease in their functional activity during the light period of the day and growth - in the dark period of the day. Light stress (24.00C: 00T) leads to significant desynchronosis and causes destructive changes in the components of the structures under study, more pronounced at 02.00 h.

Carotid artery disease leads to stroke in 30% of cases. The total frequency of carotid artery deformations varies from 10 to 40% depending on the results of angiographic and pathological examinations. Coiling of the internal carotid artery is associated with embryological pathology, and elongation and inflection are the result of fibromuscular dysplasia or changes that are accompanied by atherosclerotic damage to the arteries. Kinking – an artery bend at an acute angle. It can be congenital, when from early childhood there is a violation of cerebral circulation and develops over time from an elongated carotid artery. The formation of inflections contributes to hypertension, the progression of atherosclerosis. Coiling – the formation of a loop of an artery. Despite the smooth running of the loop, the changes in bleeding in it are significant. The nature of bends in coiling can vary depending on body position, blood pressure. The most common is the elongation of the internal carotid or spinal artery, which leads to the formation of smooth curves along the vessel. Elongation of the arteries is usually detected in random studies. The main etiological causes of pathological tortuosity of the internal carotid artery include: congenital deformation of the vascular wall, hypertension, osteochondrosis of the cervical vertebrae, compression of the bracheocephalic arteries, cranial nerves. The review article deals with anatomy and topography of the major vascular-nervous bundle components of the neck on the stages of early ontogenesis from the point of view of surgical correction of departures from their normal development in newborns and children of an early age. However, literary data are controversial and fragmentary concerning anatomical peculiarities of the carotid arteries, internal jugular vein, and vagus. The facts concerning synoptic correlation of the major vascular-nervous bundle components of the neck in fetuses and newborns are not systematized. Carotid artery disease leads to stroke in 30% of cases. The total frequency of carotid artery deformations varies from 10 to 40% depending on the results of angiographic and pathological examinations.
