Published: October 2021

The efficiency of the tractor-transport unit is largely due to its mobility, which in turn depends on many interrelated factors, such as handling, stability of movement and agility. One of the most important factors is the turnability, which ensures the ability of the tractor-transport unit to perform curved movement efficiently and safely. (Research purpose) The research purpose is in increasing the efficiency of the tractor-transport unit by using multi-link tractor trains. (Materials and methods) The main deterrent to the use of multi-link tractor trains in the Russian Federation is the increase in the overall width of the turn lane. The article presents a device that allows you to adjust the turning radius of the second trailer in order to optimize the width of the transport corridor. By changing the point of connection of the links in the turn, the movement is stabilized and the width of the transport corridor of the second link (trailer) is adjusted when moving. The article presents parameters of maneuverability of the tractor-transport train. (Results and discussion) The article presents the results of theoretical and experimental studies of the influence of the design and technological parameters of the proposed device on the maneuverability parameters of multi-link tractor-transport units. (Conclusions) The use of a towing-distributing device allows optimizing the width of the transport corridor of a multi-link tractor-transport unit by changing the turning radius of the second trailer.

Currently, manufacturers for a reliable assessment of the technical condition of volumetric hydraulic drives use the dynamic test method, which allows you to determine the torque (braking) moment on the shaft of the tested hydraulic motor. There are difficulties in reliably determining the value of the developed torque (braking) moment. (Research purpose) The research purpose is in constructing a mathematical model of the relationship between the developed torque (braking) moment of a volumetric hydraulic drive and the parameters of a hydraulic loading device. (Materials and methods) The article presents a hydraulic loading device that provides the necessary braking torque on the shaft of the tested hydraulic motor. Authors conducted one-factor and multi- factor experiments-dynamic tests of the new Sauer-Danfoss series 90 volumetric hydraulic drive using a hydraulic loading device. The torque (braking) was monitored using a non-contact digital torque sensor M 425 3-A datum electronics and a digital indicator with LCD display (Results and discussion) As a result of one-factor passive experiments, the factors influencing the optimization parameter and the ranges of their variation were determined. A mathematical model of the relationship between the developed torque (braking) moment of a volumetric hydraulic drive and the parameters of a hydraulic loading device was obtained by a multi-factor active experiment. The article presents a complete planning matrix for a multi-factor active experiment, which reflects the sequence of all possible combinations of factors that affect the optimization parameter. The most significant factors affecting the value of the developed torque (braking) moment were: the pressure drop and the temperature of the working fluid in the hydraulic lines of the hydraulic loading device. (Conclusions) The mathematical model allows us to determine with high accuracy the developed torque (braking) of the volumetric hydraulic drive.

Published: October 2021

Improving the quality of pre-sowing tillage is a priority direction. Harrowing with the use of heavy disc harrows is one of the operations of pre- sowing tillage. An important task when using heavy disc harrows is to ensure sufficient load on the working body. (Research purpose) The research purpose is in increasing the efficiency of the harrowing process by adjusting the coupling weight in the tractor–harrow link using special devices. (Materials and methods) It is important to match the necessary condition of balance between the load on the working body and the traction qualities of the tractor with a low load- bearing capacity of the soil. The article describes a regulator of the coupling weight of the harrowing unit, for which was applied a patent. The article presents the general types of connection of the device with the disk harrow frame. (Results and discussion) The proposed device allows you to redistribute the weight of the unit, thereby automatically changing the load on the working body. Authors performed experimental studies on the influence of the main design parameters of the devices on the operation of the machine and tractor unit. (Conclusions) The proposed device allows, by expanding the design and technological parameters, to regulate the depth of processing, traction characteristics and speed of the harrowing unit.
Estabilidade das decisões proferidas na ação monitória à luz do código de processo civil brasileiro
Authors: Lopes Soares de Melo Naiane
Published: October 2021

O artigo pretende analisar o grau de estabilidade das principais decisões proferidas na ação monitória à luz do Código de Processo Civil Brasileiro. A partir do método dedutivo, é analisada a relação entre a natureza da cognição (sumária ou exauriente) e a imutabilidade das decisões, aplicando-se esses pressupostos às especificidades da tutela monitória. Complementada a utilização desse método com o método dialético, são discutidas as posições doutrinárias antagônicas ou complementares sobre o tema, especialmente quanto (a) à estabilidade da decisão que defere a expedição de mandado de pagamento ou cumprimento da obrigação de entrega de coisa, fazer ou não fazer e (b) à natureza dos embargos monitórios (ação ou defesa) e o grau de estabilidade da decisão que os julga. Pelo método hermenêutico,as disposições da lei vigente são analisadas ao longo do texto, a fim de identificar em que medida as alterações legislativas mais recentes poderiam impactar essas conclusões. O artigo também se vale do método comparatístico para o resgate da doutrina italiana sobre o conceito de preclusão pro judicato, útil para análise da estabilidade da decisão que defere a expedição do mandado. Sustenta-se, a partir dessa análise, que referida decisão adquire estabilidade diversa da coisa julgada, com efeitos externos, mas sem o efeito positivo próprio da coisa julgada material. Conclui-se, ainda, que a lei vigente corrobora a visão de que os embargos monitórios têm natureza de defesa, ficando abrangidos pela coisa julgada formada pela decisão que os julga todas as alegações dedutíveis pelo réu nessa oportunidade.
Sieve tube structural variation in Austrobaileya scandens and its significance for lianescence
Authors: Losada Juan , He Zhe , Holbrook Noel
Published: October 2021

Lianas combine large leaf areas with slender stems, features that
require an efficient vascular system. The only extant member of the
Austrobaileyaceae is an endemic twining liana of the tropical Australian
forests with well-known xylem hydraulics, but the vascular phloem
continuum aboveground remains understudied. Microscopy analysis across
leaf veins and stems of A. scandens revealed a low foliar xylem to
phloem ratio, with isodiametric vascular elements along the midrib, but
tapered across vein orders. Small sieve plate pore radii increased from
0.08 µm in minor veins to 0.12 µm in the petiole, but only to 0.20 µm at
the stem base, tens of meters away. In searcher branches, phloem
conduits contained a pectin-rich wall and simple plates, whereas in
twinning stems, conduits connected through highly-angled-densely
populated sieve plates. Twisted and elongated stems of A. scandens
display a high hydraulic resistance of phloem conduits, which decreases
from leaves to stems, efficiently delivering photoassimilate from
sources under Münch predictions. Sink strength of a continuously growing
canopy might be stronger than in self-supporting understory plants,
favoring resource allocation to aerial organs in angiosperms that
colonized the vertical niche.

Published: October 2021

Background: Although many women report sexual dysfunction in the
postpartum period, controversial research has been reported the
relationship between delivery mode and sexual function. Objectives: This
meta-analysis aimed to investigate the sexual function after childbirth
and identify the difference of sexual function in women with elective
cesarean section and spontaneous vaginal delivery. Search Strategy:
Studies were found by searching in Medline, PubMed, Web of Science,
Scopus, Google Scholar databases and considering the references of the
related papers. Selection Criteria: All observational studies in English
that reported the mean and SD of score of sexual function and its
domains based on the mode of delivery were included in this
meta-analysis. Data Collection and Analysis: Finally, 17 articles with a
total population of 3410 were included in the meta-analysis. Random
effect model was used to combine the results of included studies on
female sexual function and its subdomains. Main Result: The subgroup
analysis showed that there were no significant differences in the mean
score of sexual function and subdomain among the three delivery
groups(P>0.05). However, the mean score of sexual function
was significantly differed in the term of time elapsed since delivery (P
= 0.04) and studied country (P < 0.001). Conclusions: The
result indicated that the mode of delivery are not associated with the
female sexual function. As a result, women’s preference for cesarean
section to avoid possible impairment of sexual function has gone almost
under-questioned.

Published: October 2021

To understand antibiotic resistance in pathogenic bacteria, we need to
monitor environmental microbes as reservoirs of antimicrobial resistance
genes (ARGs). These bacteria are present in the air and can be
investigated with the whole metagenome shotgun sequencing approach. This
study aimed to investigate the feasibility of a method for metagenomic
analysis of microbial composition and ARGs in the outdoor air. Air
samples were collected with a Harvard impactor in the PM10 range at 50 m
from a hospital in Budapest. From the DNA yielded from samples of PM10
fraction single-end reads were generated with an Ion Torrent sequencer.
During the metagenomic analysis, reads were classified taxonomically.
The core bacteriome was defined. Reads were assembled to contigs and the
ARG content was analyzed. The dominant genera in the core bacteriome
were Bacillus, Acinetobacter, Leclercia and Paenibacillus. Among the
identified ARGs best hits were vanRA, Bla1, mphL, Escherichia coli EF-Tu
mutants conferring resistance to Pulvomycin, BcI, FosB, and mphM.
Despite the low DNA content of the samples of PM10 fraction, the number
of detected airborne ARGs was surprisingly high.

Published: October 2021

OBJECTIVE

Data related to diabetic neuropathy in youth with type 2 diabetes are limited. We examined the relationship of glycemic control, sex, race/ethnicity, BMI, and other type 2 diabetes-associated factors with the development of diabetic peripheral neuropathy (DPN) in youth with type 2 diabetes enrolled in the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study.

RESEARCH DESIGN AND METHODS

The Michigan Neuropathy Screening Instrument (MNSI) and a 10-g monofilament exam were performed annually. DPN was defined as a score (>2) on the MNSI-exam or combined MNSI-exam and MNSI-survey scores (exam >2 and/or survey ≥4), or monofilament exam (<8 of 10 correct responses) at two or more consecutive visits. Multivariable time-to-event models assessed the association of risk factors evaluated longitudinally with DPN events.

RESULTS

A total of 674 participants (35% male), with a mean age of 14 years and diabetes duration <2 years at study entry, were evaluated annually over an average of 10.2 years. Male subjects had a significantly higher cumulative incidence of DPN than female subjects (38.5% vs. 27.2% via MNSI-exam, P = 0.002; 14.0% vs. 5.1% via monofilament exam, P = 0.01). Rates did not differ by race/ethnicity. Higher HbA1c and BMI were associated with higher DPN, by both MNSI and the monofilament test. In multivariable models, male sex, older age, and higher BMI were associated with MNSI-exam DPN risk.

CONCLUSIONS

DPN was evident early in the course of youth-onset type 2 diabetes and increased over time. It was higher in male subjects and related to glycemic control. These findings raise concern for long-term development of neuropathy-related morbidity in youth with type 2 diabetes and the need to achieve improved glycemic control.

Published: October 2021

Objective

For
people with type 1 diabetes, there are limited evidence-based resources to
support self-management when traveling across multiple time zones. Here, we compared glycemic control on Insulin Degludec versus
GlargineU100 as the basal insulin for adults using multiple daily injections (MDI)
while travelling across multiple time zones.

Research Design and Methods

This randomized crossover pilot study compared Insulin Degludec versus Glargine U100 for adults with
type 1 diabetes using MDI insulin during long-haul travel to and from Hawaii to
New York. Insulin Degludec was administered daily at the
same time regardless of time zone and Glargine was administered per travel
algorithm. Primary endpoint was
percent time in range (TIR) between 70-140 mg/dl during the initial 24 hours after
each direction of travel. Secondary
endpoints include standard continuous glucose monitoring metrics, jet lag,
fatigue and sleep.

Results

A total of 25 participants
were enrolled in the study [56% female, age 35 ±14.5 (mean ±SD) years, HbA1C
of 7.4 ±1.2% (57±13.1 mmol/mol), diabetes duration of 20.6 ±15 years). There was no significant difference in
glycemic outcomes between the two arms of the study including TIR, hypoglycemia
or hyperglycemia. Neither group achieved >70% TIR 70-180
mg/dL during travel. Jetlag was greater
on Glargine U100 in Eastward travel but not Westward. Fatigue was greater after
Westward travel on Glargine. Sleep was not significantly different between basal
insulins.

Conclusion

In adults with type 1
diabetes using MDI of insulin and travelling across multiple time zones, glycemic
outcomes were similar comparing Insulin Degludec and Glargine U100.
Comparative study of filament-fed and blown powder-based laser additive manufacturing for transparent magnesium aluminate spinel ceramics
Authors: Pappas John M. , Dong Xiangyang
Published: October 2021

Magnesium aluminate spinel is of great interest as a transparent ceramic for its excellent mechanical properties and excellent optical transmittance. Additive manufacturing of this desirable material presents several benefits over traditional manufacturing methods, including reduced fabrication time and cost and the potential to fabricate structures with complex geometries and internal cooling networks. Despite the many benefits, the challenges hindering this technology must be overcome. A primary challenge with powder-based laser additive manufacturing of transparent ceramics is a trade-off between densification and cracking. The fabrication of transparent ceramics requires nearly full densification since pores act as light scattering centers. Even relatively small percentages of porosity render ceramics translucent or opaque. Previous studies on powder-based laser direct deposition of spinel ceramics have shown that densification to transparency is possible with high-laser power deposition. While high-laser powers are beneficial for densification, it also produces high thermal gradients that result in significant crack formation. Cracks hinder mechanical properties and transparency, limiting possible applications. Thus, we propose a filament-based deposition strategy to reduce laser power requirements. Filament-fed laser direct deposition, instead of blown powder, dramatically reduced the amount of gas porosity within the melt. Hence, highly densified, transparent, spinel ceramics were fabricated. Through decreased laser power requirements for high densification, cracking was largely reduced. This paper provides a comprehensive comparison between filament- and powder-based laser direct deposition by analyzing important sample characteristics, including porosity, cracking, grain size, and their controlling mechanisms. This paper also presents a laser direct deposition and postprocessing method to manufacture predensified spinel filaments.
Utviklingspolitikken: En revolusjon er en illusjon?
Authors: Hagen Rune Jansen
Published: October 2021

Bærekraftsmålene har blåst nytt liv i debatten om hvorvidt globale fellesgoder kan og bør finansieres med bistand. I denne replikken til Nikolai Hegertuns essay En stille revolusjon av utviklingspolitikken, argumenterer jeg for at det er liten grunn til å være strengt normativ i dette spørsmålet, blant annet fordi den statistiske definisjonen av bistand ikke utelukker dette; det er presedens for en viss bruk av bistand for slike formål; bistandsvolum uansett ikke er et fullstendig mål på givernes innsats og sier lite om kvaliteten på den; og fordi en rekke nasjonale og regionale fellesgoder – som uten tvil kan finansieres med bistand – er nødvendige for at globale fellesgoder skal kunne produseres eller konsumeres av innbyggere i fattige land. Vi vet heller ikke med sikkerhet at tradisjonell bistand gir større velferdsøkninger i fattige land enn finansiering av globale fellesgoder. Det er mulig å se for seg både at de globale utfordringene sluker bistanden og at de gir støtet til internasjonalt samarbeid i et omfang vi ikke har sett før. Gitt de underliggende drivkreftene – en kombinasjon av altruisme og egeninteresser – er det mer sannsynlig med gradvise endringer i utviklingspolitikken enn en revolusjon.
Abstract in English:Development Policy: Revolution is an Illusion?The Sustainable Development Goals have reinvigorated the debate on whether aid can and should be used to finance global collective goods. In this comment on Nikolai Hegertun’s essay Aid’s Silent Revolution? (En stille revolusjon av utviklingspolitikken), I argue that the statistical definition of aid does not categorically rule out such financing, for which there are precedents; that aid volumes in any case do not tell the full story about the extent and quality of donor efforts; and that many national and regional collective goods – which certainly can be financed by aid – are necessary for the production and enjoyment of global collective goods by individuals living in developing countries. Moreover, we do not know with certainty that traditional aid produces greater welfare improvements in such countries than global collective goods do. It is possible to envisage both that current global challenges will swamp aid and that they will induce international cooperation on an unprecedented scale. However, given the underlying forces of altruism and national self-interest, a gradual change in development policy is more likely than a revolution.

Metabolic Syndrome in Type 1 Diabetics: Prevalence and Clinicobiological Features
Authors: Htira Y. , Mankai A. , Hadj Ali Z. , Ben Mami F.
Published: October 2021

Background: Because of the world obesity epidemic, some type 1 diabetics exhibit clinical-biological features of metabolic syndrome. Few studies have investigated the association between this syndrome and this type of diabetes.
Aim: To estimate the prevalence of metabolic syndrome in type 1 diabetics and to study the relationship between this syndrome and the clinical-biological profile of these patients.
Methods: We carried out a cross-sectional study, involving type 1 diabetics, monitored at the National Institute of Nutrition in Tunis. All of these patients underwent a clinical examination and laboratory workup.
Results: We included 150 patients. The mean age of the patients was 31.25 ± 10.3 years. Women represented 54% of the patients. Abdominal obesity was found in 61.7% of women and 14.5% of men. The metabolic syndrome was found in 30.7% of patients, with a female predominance (48.1% vs. 10.1% in men, p <0.001). Comparing the two groups with and without metabolic syndrome, the latter was significantly correlated with sedentary lifestyle, daily insulin dose, hypertriglyceridemia, hypoHDL-cholesterolemia and arterial hypertension, but not correlated with the age of the patients, the duration of diabetes or the glycemic control.
Conclusion: This work reveals a high prevalence of metabolic syndrome in type 1 diabetics in whom it seems relevant to look for the components of this syndrome, each considered to be a cardiovascular risk factor in its own right.
Rhyolites of the Kiliya-Zmeinyi uplift on the Black Sea shelf: geochemical evidence of a non-subduction boundary between the East European Platform and the Scythian Plate
Authors: Shnyukova K.Ye.
Published: October 2021

The geochemistry of rhyolites uncovered at shallow depth by a borehole on the Kiliya-Zmeinyi uplift of the Black Sea northwestern shelf northeast of Zmeinyi island, in the junction zone of the East European platform and the Scythian plate, has been studied for the first time. This zone is considered by many geologists and geophysicists as a Late Paleozoic collisional suture that had been formed due to subduction of oceanic crust of the ocean, which adjoined the East European platform from the south, under the Scythian plate; it is traced from Dobrudzha to the Caspian Sea and named North Crimean. To check the subduction nature of the boundary between the East European platform and the Scythian plate, igneous rocks’ geochemical characteristics beeng indicators of various geodynamic regimes were used. A petrogeochemical comparison of rhyolites from the borehole in Zmeinyi area with acid igneous rocks known nearby has been carried out, namely with: 1) Late Permian subalkaline granites and rhyolites Turcoaia of the Macin zone of Northern Dobruja; 2) Triassic and / or Triassic-Jurassic trachyrhyolites and rhyolites of the Tulcea zone of Northern Dobruja and the Tatarbunar complex of the Pre-Dobruja depression. Some acid rocks of various ages and genesis from the southernmost margin of the Scythian plate (southwestern Crimea on- and offshore) were taken additionally for comparison. According to the distribution of rare earth elements, the position on the discriminant geochemical diagrams and the shape of curves on the multicomponent spider diagrams, the rhyolites of the Kiliya-Zmeinyi uplift exhibit not subduction but intraplate geochemical features closest to those of granites and rhyolites Turcoaia of the Macin zone of Northern Dobruja. Considering that the latter are reputed to be Late Permian, one can assume the same age for the rhyolites from the borehole in Zmeinyi area. Taking into account section features, geophysical information and geochemical similarity of magmatism, Kiliya-Zmeinyi uplift of the northwestern shelf seems to be a continuation of the Northern Dobruja structure into the Black Sea; it was a part of the hypothetical Late Paleozoic Euxinian orogen near its northern boundary. An absence of subduction geochemical properties in the studied presumably Late Permian rhyolites indicates that the junction zone of the East European platform and the Scythian plate in the Ukrainian shelf area is not a Late Paleozoic suture, but rather represents a thrust of the Euxinian orogen.
The use of the vulnerability factor in the study of vibration signals on the soil surface from the movement of subway electric trains
Authors: Senin L.N. , Senina T.Ye.
Published: October 2021

Microseismic vibrations of the upper part of the soil strata occur continuously under the influence of endogenous and exogenous processes of both natural and artificial origin. Micro-oscillations of technogenic nature are especially characteristic of densely built-up urban areas. The practice of monitoring seismological monitoring observations shows that under such conditions it is possible to observe various types of microseismic vibrations, including elastic vibration signals in the frequency range of 1—100 Hz, generated by passing subway trains. In the calculations of the seismic stability of the designed structures, special attention is paid to the resonance characteristics of the upper part of the soil strata, which at certain frequencies can significantly enhance seismic vibrations, for example, from external vibrations sources. By traditional methods, the characteristics of resonant oscillations and their accounting are carried out, as a rule, with an insufficient degree of reliability and completeness, as a result of whichand so they are usually used as auxiliary ones. In this paper, a methodological complex is considered using modern methods for measuring and processing microseismic signals in order to identify areas with maximum amplitudes of response to external elastic influences in the study area for construction and take them into account in the future in design and construction. The study of vibroseismic noises formed on the surface of the soil layer, for example, by passing subway trains, allows one to estimate the amplitude-frequency properties of these soils, and the spectral ratio of horizontal displacements of soils to vertical H/V and the derivative of these ratios — the coefficient of vulnerability of the Ky — provide a confident selection of weakened zones that are subject to the greatest impact of external elastic vibrations.

Descriptive statistics and the chi-square Kruskal-Wallis and Mann-Whitney U tests were applied. The mean addiction score was significantly higher in women than in men (p≤0.05). The students in the study mainly (71.1%) used smartphones to access the internet. Total addiction levels were significantly higher among participants who checked their phones immediately upon waking (p<0.05). Studies of smartphone addiction are insufficient, and different results may be yielded by studies on the subject from different universities.
The Manjanguak Tradition: Social Learning, Character Education and Psychological Effects
Authors: Sukma Dina
Published: October 2021

The "manjanguak" tradition is a series of funeral ceremonies held at the funeral home which is attended by family and relatives. The study of the manjanguak tradition is more concerned with the social values contained in it such as value of character education. This is because the manjanguak tradition is a tradition that exists in the human social realm that contains character education values. However, there has not been much discussion of its influence on the individual psychological aspects of this tradition. Humans are social creatures that are closely related to their environment. Humans who are detached from social ties will experience mental health problems such as low self-esteem and low self-control. Therefore, this article is a literature review that discusses all the dimensions contained in the manjangauak tradition. This article focuses not only on the social learning process and the values of character education, but also on the individual psychological effects of the manjanguak tradition.

Published: October 2021

The article presents literature data andown observations of some rare congenital malformationsof the colorectal area in newborns that require surgicaltreatment. These are defects such as congenital pouch colonand congenital segmental dilatation of the colon. Thereare isolated cases of birth of children with these defectsin European countries and North America. They are morecommon in Asian countries, especially in India. Diagnosisand surgical correction of such congenital malformationscause difficulties associated with insufficient awarenessof pediatric surgeons, neonatologists, pediatricians aboutthis pathology. Data is presented on clinical manifestations,antenatal and postnatal diagnosis and treatment tactics, aswell as the histopathological structure of the affected colonin these defects.The analysis of literature data and the presented clinicalobservations of congenital pouch colon and congenitalsegmental dilatation of the colon in newborns indicate thepossibility of their antenatal and preoperative diagnosis.It is concluded that children with anorectal malformationsand Hirschsprung's disease require a thorough differentialdiagnosis with congenital pouch colon and segmentaldilatation of the colon, as the tactics of their surgicalcorrection significantly differ from the treatment tacticsof common anorectal malformations and Hirschsprung'sdisease surgical management.

From year to year prescription of probioticsremains a controversial issue both in medicine for adults andpediatrics. Some doctors make a positive conclusion about theeffectiveness of probiotics, while large individual tests beinga part of meta-analyses show negative results pointing that acertain probiotic strain has no influence on a patient. It’s betterto avoid excessively negative or positive conclusions CRTabout probiotics. The issue of using probiotics in newborns isespecially acute among neonatologists. The aim of this articleis the analysis of the latest data on the possibility of usingprobiotics in newborns.In 2021 the clinical report about the use of probiotics inpremature newborns in the USA was published (ААР committeeon fetus and newborns issue). It pointed out that the numberof premature newborns who get prescriptions for probiotics,namely in the USA, is steadily increasing despite significantdifferences in combinations of probiotic drugs and absenceof pharmaceutical class of probiotic products. Accordingto the latest source of database in the USA, around 10% ofnewborns with extremely low gestational age get a certaintype of probiotics while being in the intensive care unit fornewborns with different variations among the units. Despitethe fact that lots of doctors argue their usual use of probioticsin premature newborns, other groups, including ESPGHANand АРР are more cautious admitting the main restrictions ofmany researches, methodological differences in the design ofa research and guidelines along with the conclusion that theeffectiveness of probiotics may vary widely.Recently the ESPGHAN working group on probiotics andprebiotics has published the document on using an approachof network meta-analysis of finding strains with the largestpotential of effectiveness to prevent major diseases inpremature newborns. Following this the ESPGHAN committeeon feeding issue and the ESPGHAN working group onprobiotics and prebiotics have an aim to develop a documentwhich can serve as a guidance for possible use of probiotics inpremature newborns the positions of which we will consider inthe second part of the article.

The issue related to the study of anthroposcopic, anthropometric, dermatoglyphic parameters of the population of Ukraine to create regional gene pools remains relevant, because given the intensification of migration processes both within Ukraine and worldwide. The growing flow of global migration and assimilation creates all the conditions for the disappearance of pure ethnic groups and peoples. This work highlights the prospects for studying the ethnic and regional features of human anthroscopic parameters. The article presents the differential anthroscopic characteristics of Hutsul, Boyko, Lemko, Opollia, Pokuttia ethno-territorial groups.

The goal of the work. To form anthroscopic portraits of Hutsul, Boyko, Lemko, Opollia, Pokuttia ethno-territorial groups in comparison with the control group of persons.

Materials and methods. The material of the study was anthroscopic parameters of 480 males and females aged 18-59 years, belonging to the Hutsul, Boyko, Lemko, Opollia, Pokuttia and control groups, obtained by questionnaires using standardized methods proposed by Ginsburg BB (1963). The obtained data were subjected to statistical analysis.

Results. Anthroposcopic portrait of the studied groups: Hutsul ethno-territorial group is characterized by dark skin tone, black straight hair, oval elongated straight face, dark brown or green-brown eyes, long narrow nose; Boyko ethno-territorial group is marked by white skin color, blond straight or wavy hair, round broad face, gray or dark brown eyes, wide straight nose; the Lemko ethno-territorial group is distinguished by white skin color, light straight or curly hair, oval elongated narrow long face, light brown and blue eyes, narrow straight nose; Opole ethno-territorial group is characterized by white skin color, light blond and dark blond wavy hair, round broad face, dark brown and light brown eyes, straight wide nose; The Pokut ethno-territorial group is distinguished by white skin, black and dark blond straight hair, an oval elongated narrow face, brown-green eyes, and a long narrow nose.

Conclusion. We were able to apply the obtained results in practice, including in the set of identification features and developing an algorithm for rapid prediction of human outward signs.

Authors: Lisowski Józef
Published: October 2021

The article presents four main chapters that allow you to formulate an optimization task and choose a method for solving it from static and dynamic optimization methods to single-criterion and multi-criteria optimization. In the group of static optimization methods, the methods are without constraints and with constraints, gradient and non-gradient and heuristic. Dynamic optimization methods are divided into basic - direct and indirect and special. Particular attention has been paid to multi-criteria optimization in single-object approach as static and dynamic optimization, and multi-object optimization in game control scenarios. The article shows not only the classic optimization methods that were developed many years ago, but also the latest in the field, including, but not limited to, particle swarms.
Women Journalists and Social Media Activism: An Analysis of the Hashtags #DeixaElaTrabalhar and #LasPeriodistasParamos on Instagram
Authors: López-Ortega Marin , Noronha Iara
Published: October 2021

The social media collective actions through the hashtags #DeixaElaTrabalhar and #LasPeriodistasParamos raised problems that women journalists were suffering in both Brazil and Spain. While the representation of feminism has long been studied, less attention has been paid to comparative studies and the more personal representation. Focusing on a combination of visual and textual qualitative content analysis, we explore 90 Instagram posts from women journalists within the two hashtags and how they portray themselves in relation to their profession. At the time of writing, Instagram is one of the most popular social networks focused on the publication of audiovisual content. This makes it suitable for the study of online self-representation. The article identifies using the Documentary Image Analysis and the Critical Discourse Analysis the recurrent demands and denunciations regarding journalism gender-related issues and finds common visual vernaculars in #DeixaElaTrabalhar and #LasPeriodistasParamos posts. This study makes a comprehensive analysis of how women journalists construct their identity on Instagram images concerning the topics they talk about and the elements they use to insert themselves in the female journalists’ collectives and connects it with the theories on feminism and social media activism. The results reported here shed new light on how female journalists take control over their situation and find empowerment, feminism, non-violent protest, and professional/private life to be common points regarding the identity construction in relation to these online groups.
