La endometritis se define como la inflamación del endometrio, y es considerada una de las principales causas de sub e infertilidad en la yegua, que generan pérdidas económicas significativas, con una incidencia del 10 al 15 %. Existen diferentes etiologías, destacándose la mala conformación del perineo, útero abdominal, pérdida de la actividad miometrial, número de montas, factores moleculares y genéticos, y la presencia de bacterias y hongos. El presente artículo expone el caso de una yegua criolla colombiana de 15 años con historial de abortos y nula obtención de embriones, donde fueron realizados como métodos diagnósticos la evaluación del sistema genital externo e interno, ultrasonografía, citología, cultivo y biopsia endometrial; la cual reportó endometritis crónica de clasificación II B, asociada edema tipo 4, y estableciendo un pronóstico reservado para la reproducción, después de comprobarse la endometritis fúngica. El tratamiento consistió en la utilización de complejos vitamínicos, medicina biorreguladora, terapia antimicótica y antibiótica, nutraceúticos, minerales, y lavados intrauterinos. Posterior a la medicación y tres intervalos ovulatorios consecutivos, fueron recuperados y transferidos exitosamente cuatro embriones, de los cuales tres llegaron a término, demostrando así la recuperación de la función endometrial, gracias a la identificación de los microorganismos involucrados y el establecimiento de una terapia adecuada y complementada.
Formation of the Linguistic Picture of the World of Bilinguals

Published: December 2022

The authors of the article analyze the specifics of the formation of the linguistic picture of bilinguals, in whose minds two cultural codes are combined. The authors suggest that the linguistic picture of the world of bilinguals differs from the picture of a native speaker. When forming a bilingual linguistic personality, two cultures merge in his mind; many historical, social facts, influenced by individual and personal views, judgments, assessments, get a brighter color, are described differently, which makes it possible to understand the worldview of another person. Natural bilinguals, unlike artificial ones, have a combination of two pictures of the world, two cultural codes. However, both pictures in the mind of a bilingual, who is not divorced from one of the language environments, combine, change and eventually form another one with its own specific features. Bilingual writers, in whose minds two different languages are combined, using, for example, the Russian language when creating their work, nevertheless find themselves in the system of images of their native language, native culture. As a result, expressions, stylistic techniques and other means of artistic expression that are atypical for native speakers appear. This is how a new cultural code appears, which requires special linguistic means. A bilingual writer evaluates any phenomenon from the point of view of the native cultural The article provides examples: some characteristic features of the work of the Swedish bilingual writer of Greek origin Theodor Kallifatides, Russian-American writer V.V. Russian Russian and Kyrgyz literature by Chingiz Aitmatov, Russian French writer Andrei Makin. A bilingual author, in whose mind two different worlds are connected, nevertheless is closer to the system of images of his native language, native culture.
The Reality of Erzya-Russian Poetic Bilingualism: the Artistic Phenomenon of Alexander Arapov
Authors: Arzamazov Aleksey A.
Published: December 2022

The article deals with the problematic and thematic projections of the work of Alexander Arapov (1959-2011), one of the most prominent representatives of modern Mordovian literature. The author focuses on the complex reality of Erzya-Russian poetic bilingualism, the study of which allows us to conclude that each of the languages has certain motive-figurative complexes, aesthetic ideas, ethno-psychological attitudes, linguo-poetic features, “voices” of traditions. So, the central place in the Russian-language poems of A.V. Arapova is occupied by existential-psychological motives, the “I”-subject analyzes the events of his life, gives them an assessment, while a negative emotional background prevails, a discrepancy between the desired and the actual is indicated. It is indicative that the theme of ethnic identity, almost obligatory for the national literature, is practically not revealed in the poems created in Russian, there are no examples of “connection” of the ethno-cultural component. One of the identified linguistic and poetic details is the representativeness of the infinitive writing. The Erzya texts analyzed by the author are far from social contexts, urban life, they have little reflection on the acutely experienced modernity. In the Erzya texts, landscape lyrics are dominant, the figurative and symbolic elements of the Mordovian ethnoculture are updated, the influence of national folklore is felt. The author’s desire for linguistic purism is noticeable in the poems in the Erzya language. Thus, it has been established that the reality of the Erzya-Russian poetic bilingualism of Alexander Arapov is not just two genetically different languages, but also two different artistic worldviews, the intersections between which are not so many.
A Comparative Analysis of the Socio-Cultural Context in Textbooks of Minority Languages for Non-native Speakers (Based on Electronic Textbooks of Udmurt and Swedish languages)
Authors: Eiassu Semyon T. , Lapteva Marina D.
Published: December 2022

The article presents the results of a comparative analysis of the socio-cultural context of textbooks of the Udmurt and Swedish languages as minority and non-native languages. The preservation and development of minority languages is outlined and Russian and Finnish experience in the area is compared. The aim of the study was to identify the features of the socio-cultural models of these textbooks by applying the method of content analysis and to analyze them in terms of the interests and communicative needs of teenage students. The material for the analysis was electronic textbooks of the Udmurt language of the «Ӟеч-а, бур-а, удмурт кыл!» (“Hello, Udmurt language!”) series, as well as electronic textbooks of Swedish of the Megafon series, both for grades 7-9. Materials of the kind have not been previously considered in similar studies. The results of the comparative analysis show that textbooks meet the communicative needs of adolescent students in different ways. Conclusions are drawn about the difference in the groups of students to whom these textbooks are oriented. A proposal is formulated on the use of the socio-cultural context as a resource in the popularization of minority languages.

Authors:   University of Latvia, Faculty of Education, Psychology and Art, Dreimane Lana Frančeska , Zālīte-Supe Zinta
Published: December 2022

Education and learning are evolving because of the rapid speed of technological advancement in the 21st Century. Virtual Reality (VR) has emerged as one of the high-potential learning technologies for education and training purposes across a vast range of fields. In sport education VR has been utilised to enable learners to access learning environments and experiences for drill-training, complex conceptualisation and problem-solving skills. This paper presents an instructional design map for developing and improving fencing skills utilising VR technology. This interactive fencing training simulation is aimed to help to develop a solid en garde position, balanced movements, correct weapon and body position, as well as providing tactical advice and support for advanced principles of performance. Fencing is a combat sport where fencers compete in three weapon disciplines. This study focuses on one of these weapon disciplines – the foil. To develop a proposed solution three main tasks were undertaken – study of current scientific literature as well as analysis of existing VR fencing training solutions and expert interviews with professional coaches and the professional athletes. This research addresses the lack of a systematised knowledge base by examining scientific literature and analysing case study experience in order to design the basic criteria that will be used in the development of a VR learning experience for fencing training in an immersive VR environment.

Authors:   University of Latvia, Svence Guna , Briška Ilze
Published: December 2022

Research on social-emotional health and resilience of Latvian teachers was conducted as part of the ERASMUS+ project “Supporting teachers to face the challenge of distance teaching”. The aim of this study is to assess teachers’ social-emotional health and resilience to reveal those areas which require significant support and development in the Covid-19 pandemic situation. In the article, the concepts used in the project – social-emotional health, resilience, covitality will be theoretically analysed to substantiate the structure of the empirical study. Teachers’ mental health was tested using Social-emotional Health Survey– Teachers SEHS-T (Furlong et al., 2017; Furlong et al., 2014; Furlong & Gajdošová, 2018, as mentioned in Lapiņa, 2021) and Resilience Scale RS 25 (Wagnild & Young, 1993; Wagnild, 2009; Wagnild, 2016) with supplementary questions. 636 teachers of general and vocational schools took part in the research. The results identified that positive teachers’ strengths are self-regulation, empathy, and cognitive reappraisal. However, the teachers demonstrated limits in resilience as such, and in some scores of SEHS-T, as in covitality domain Belief in Others, especially in institutional and colleagues’ support, and in Engaged Living – gratitude and zest. The identified weaknesses and limits will be used as a foundation for preparing further intervention activities – a digital psychological support programme for strengthening the teachers’ resilience and mental health in general.

Introduction: Ventricular arrhythmia (VA) from the left
ventricular summit (LVS) is a common origin of VA, which resulting LV
dysfunction in some patients. However, the predictors of LV
cardiomyopathy were not well-elucidated. The present study sought to
investigate the risk factor of LV cardiomyopathy and the outcome in
patients with LVS VA Methods: Between 2013 and 2018, a total of
139 patients (60.7% men; mean age 53.2 ± 13.9 years-old) underwent
catheter ablation for LVS VA from two centers. Detailed patient
demographics, electrocardiograms, electrophysiological characteristics,
and clinical outcomes were extracted for analysis. LV cardiomyopathy was
defined as LV ejection fraction (LVEF) <50%.
Results: Acute procedural success was achieved in 92.8 % of
patients. There were 40 patients (28.8%) with LV cardiomyopathy, and
the mean LVEF improved from 37.5 ± 9.3% to 48.5 ± 10.2% after ablation
( p < 0.001). After multivariate analysis, the
independent predictors of LV dysfunction were wider QRS duration of the
VA (odds ratio [OR]1.02; 95% confidence interval [CI]:
1.00-1.04; p = 0.046) and the absolute earliest activation time
discrepancy (AEAD) between epicardium and endocardium (OR 1.05; 95%
confidence interval CI: 1.00-1.09; p = 0.048). After ablation,
the LV function was completely recovered in 20 patients (50%). The
predictors for irreclaimable LV function included wider PVC QRS duration
(OR 1.09; 95% CI: 1.02-1.17; p = 0.012) and poorer LVEF (OR
0.85; 95% CI: 0.74-0.97; p = 0.020). Conclusion: In
patients with VA from LVS, PVC QRS duration and AEAD predicted the
deteriorating LV systolic function. Catheter ablation could reverse the
LV remodeling. Narrower QRS duration and better LVEF predicted a better
recovery of LV function after ablation.
Characterisation and automated quantification of induced seizure-related behaviours in Xenopus laevis tadpoles

Published: December 2022

Epilepsy, a clinical diagnosis characterized by paroxysmal episodes
known as seizures, affects 1% of people worldwide. Safe and
patient-specific treatment is vital and can be achieved by the
development of rapid pre-clinical models of for identified epilepsy
genes. Epilepsy can result from either brain injury or gene mutations,
and can also be induced chemically. Xenopus laevis tadpoles could
be a useful model for confirmation of variants of unknown significance
found in epilepsy patients, and for drug re-purposing screens that could
eventually lead to benefits for patients. Here, we characterise and
quantify seizure-related behaviours in X. laevis tadpoles arrayed
in 24-well plates. To provoke acute seizure behaviours, tadpoles were
chemically induced with either pentylenetetrazole (PTZ) or
4-aminopyridine (4-AP). To test the capacity to adapt this method for
drug testing, we also exposed induced tadpoles to the anti-seizure drug
valproate (VPA). Four induced seizure-like behaviours were described and
manually quantified, and two of these (darting, circling) could be
accurately detected automatically, using the video analysis software
TopScan. Additionally, we recorded swimming trajectories and mean
swimming velocity. Automatic detection showed that either PTZ or 4-AP
induced darting behaviour and increased mean swimming velocity compared
to untreated controls. Both parameters were significantly reduced in the
presence of VPA. In particular, darting behaviour was a shown to be a
sensitive measure of epileptic seizure activity. While we could not
automatically detect the full range of seizure behaviours, this method
shows promise for future studies, since X. laevis is a
well-characterised and genetically tractable model organism.
Pro-inflammatory cytokines IL-1α, IL-6 and TNF-α in major depressive disorder: Sex-specific associations with psychological symptoms

Published: December 2022

The pro-inflammatory cytokines IL-1α, IL-6 and TNF-α are associated with
major depressive disorder, psychological distress, cardiovascular
health, and obesity. However, there is limited research that has
examined multiple associations between these variables, among
individuals with major depressive disorder in comparison to a control
cohort, including sex differences. In this study, data was analysed from
60 individuals with major depressive disorder and 60 controls, including
plasma IL-1α, IL-6 and TNF-α, adiposity measures (body mass index; waist
circumference), cardiovascular health indices (blood pressure; heart
rate) and psychological symptoms (depressive severity; anxiety;
hostility; stress). The cytokines were compared by group and sex, and
correlated with measures of adiposity, cardiovascular health indices and
psychological health. Plasma IL-1α and IL-6 were higher in major
depressive disorder group versus control, but with a sex interaction for
IL-6, with this group difference only among females. TNF-α did not
differ between groups. IL-1α and IL-6 correlated with depressive
severity, anxiety, hostility, and stress, while TNF-α correlated only
with anxiety and hostility. Psychopathology was associated with IL-1α in
males only, and with IL-6 and TNF-α in females only. None of the
cytokines correlated with body mass index, waist circumference, blood
pressure or heart rate. The result of group by sex interaction for IL-6,
and sex specific associations between pro-inflammatory cytokines and
psychometrics could be aetiologically important in depression
interventions and treatments for females versus males, warranting
further investigation.
NURSE ENTREPRENEURSHIP IN THE EMERGING HEALTHCARE INDUSTRY: A SYSTEMATIC REVIEW
Authors: Tekin Perihan Senel , BEKAR Fevziye
Published: December 2022

Entrepreneurship is encouraged in every sector in the twenty-first
century. In the field of health, nurse entrepreneurship emerges as an
important issue in providing health services and improving public
health. In this research, the development of entrepreneurial behavior in
nursing in the world and a systematic examination of this development
within the framework of academic knowledge are aimed. For this purpose,
the types of entrepreneurship discussed in the last 10 years of research
in the field of entrepreneurship in nursing and the methods, findings
and results of these studies were examined. As a result of the search
made in databases with high international recognition, 78.761
publications on nurse entrepreneurship were reached in the last ten
years, and 30 articles were included in the final review. Classical,
social, collective and intrapreneurship were discussed in these studies,
which were examined in terms of entrepreneurship typology. As a result
of the review, it was seen that the studies in the literature mostly
focused on the opportunities and obstacles in front of entrepreneurial
nurses. While collective entrepreneurship was included for the first
time in the literature, it was found that eco-entrepreneurship and
digital entrepreneurship have not yet been the subject of research on
nurse entrepreneurship. However, it has been found that more research is
needed on the relations between entrepreneurial nurses and
non-governmental organizations, the incentives for increasing
entrepreneurship and role modeling in entrepreneurship.
Pathways of Nitrous Oxide Production in the Eastern Tropical South Pacific Oxygen Minimum Zone

Published: December 2022

Oceanic emissions of nitrous oxide (N2O) account for roughly one-third
of all natural sources to the atmosphere. Hot-spots of N2O outgassing
occur over oxygen minimum zones (OMZs), where the presence of steep
oxygen gradients surrounding anoxic waters leads to enhanced N2O
production from both nitrification and denitrification. However, the
relative contributions from these pathways to N2O production and
outgassing in these regions remains poorly constrained, in part due to
shared intermediary nitrogen tracers, and the tight coupling of
denitrification sources and sinks. To shed light on this problem, we
embed a new, mechanistic model of the OMZ nitrogen cycle within a
three-dimensional eddy-resolving physical-biogeochemical model of the
ETSP, tracking contributions from remote advection, atmospheric
exchange, and local nitrification and denitrification. Our results
indicate that net N2O production from denitrification is approximately
one order of magnitude greater than nitrification within the ETSP OMZ.
However, only ~30% of denitrification-derived N2O
production ultimately outgasses to the atmosphere in this region
(contributing ~34% of the air-sea N2O flux on an annual
basis), while the remaining is exported out of the domain. Instead,
remotely-produced N2O advected into the OMZ region accounts for roughly
half (~56%) of the total N2O outgassing, with smaller
contributions from nitrification (~7%). Our results
suggests that, together with enhanced production by denitrification,
upwelling of remotely-derived N2O (likely produced via nitrification in
the oxygenated ocean) contributes the most to N2O outgassing over the
ETSP OMZ.

River flows change on timescales ranging from minutes to millennia.
These variations influence fundamental functions of ecosystems,
including biogeochemical fluxes, aquatic habitat, and human society.
Efforts to describe temporal variation in river flow—i.e., flow
regime—have resulted in hundreds of unique descriptors, complicating
interpretation and identification of global drivers of flow dynamics.
Here, we used a cross-disciplinary analytical approach to investigate
two related questions: 1. Is there a low-dimensional structure that can
be used to simplify descriptions of streamflow regime? 2. What catchment
characteristics are most associated with that structure? Using a global
database of daily river discharge from 1988-2016 for 3,120 stations, we
calculated 189 traditional flow metrics, which we compared to the
results of a wavelet analysis. Both quantification techniques
independently revealed that streamflow data contain substantial
low-dimensional structure that correlates closely with a small number of
catchment characteristics. This structure provides a framework for
understanding fundamental controls of river flow variability across
multiple timescales. Climate was the most important variable across all
timescales, especially those lasting several weeks, and likely
contributes as much as dams in controlling flow regime. Catchment area
was critical for timescales lasting several days, as was human impact
for timescales lasting several years. In addition, both methods
suggested that streamflow data also contain high-dimensional structure
that is harder to predict from a small number of catchment
characteristics (i.e. is dependent on land use, soil structure, etc.),
and which accounts for the difficulty of producing simple hydrological
models that generalize well.
Double reservoirs imaged below Great Sitkin Volcano, Alaska, explain the migration of volcanic seismicity

Published: December 2022

Volcanic seismicity provides essential insights into the behavior of an
active volcano across multiple time scales. However, to understand how
magma moves as an eruption evolves, better knowledge of the geometry and
physical properties of the magma plumbing system is required. In this
study, using full-wave ambient noise tomography, we image the 3-D
crustal shear-wave velocity structure below GreatSitkin Volcano in the
central Aleutian Arc. The new velocity model reveals two low-velocity
anomalies, which correlate with the migration of volcanic seismicity.
With a partial melt of up to about 30%, these low-velocity anomalies
are characterized as mushy magma reservoirs. We propose a six-stage
eruption cycle to explain the migration of seismicity and the
alternating eruption of two reservoirs with different recharging
histories. The findings in this study have broad implications for the
dynamics of magma plumbing systems and the structural control of
eruption behaviors.

Published: December 2022

The ability of satellite instruments to accurately observe long-term
changes in atmospheric temperature depends on many factors including the
absolute accuracy of the measurement, the stability of the calibration
of the instrument, the stability of the satellite orbit, and the
stability of the numerical algorithm that produces the temperature data.
We present an example of algorithm instability recently discovered in
the temperature dataset from the SABER instrument on the NASA TIMED
satellite. The instability resulted in derived temperatures that were
substantially colder than anticipated from mid-December 2019 to
mid-2022. This algorithm-induced change in temperature over one to two
years corresponded to the expected change over several decades from
increasing anthropogenic CO2. This paper highlights the importance of
algorithm stability in developing Geospace Data Records (GDRs) for
Earth’s mesosphere and lower thermosphere. A corrected version (Version
2.08) of the temperatures from SABER is described.
On the Control of Soil Heterogeneity, Peclet number and Spatially Variable Diffusion over Unsaturated Transport
Authors: Henri Christopher Vincent , Diamantopoulos Efstathios
Published: December 2022

Physical properties of soils are ubiquitously heterogeneous. This
spatial variability has a profound, yet still partially understood,
impact on conservative transport. Moreover, molecular diffusion is often
a disregarded process that can have an important counter-intuitive
effect on transport: diffusion can prevent non-Fickian tailing by
mobilizing mass otherwise trapped in low velocity zones.

Here, we focus on macroscopically homogeneous soils presenting small
scale heterogeneity, as described by the Miller-Miller method. We then
analyze the dynamic control of soil heterogeneity, advection and
diffusion on conservative transport. We focus especially on the
importance of diffusion and of its tortuosity-dependent spatial
variability on the overall transport.

Our results indicate that high Peclet number systems are highly
sensitive to the degree of heterogeneity, which promotes non-Fickian
transport. Also, diffusion appears to have a profound impact on
transport, depending on both the degree of heterogeneity and the Peclet
number. For a high Peclet number and a very heterogeneous system,
diffusion leads to the counter-intuitive decrease of non-Fickian
macrodispersion described previously. This is not observed for a low
Peclet number due to the non-trivial impact of the spatial variability
in the diffusion coefficient, which appears to be a significant
controlling factor of transport by promoting or preventing the
accumulation of mass in low velocity zones.

Globally, this work (1) highlights the complex, synergistic effect of
soil heterogeneity, advective fluxes and diffusion on transport and (2),
alerts on potential upscaling challenges when the spatial variability of
such key processes cannot be properly described.
Products and dynamics of lava-snow explosions: the 16 March 2017 explosion at Mt Etna (Italy)

Published: December 2022

Volcanic hazards associated with lava flows advancing on a snow cover
are often underrated. On 16 March 2017, during a mild effusive-explosive
eruption at Mt Etna (Italy) a slowly advancing lava lobe interacted with
the snow cover producing a sudden, short-lasting sequence of explosions.
White vapor, brown ash and coarse material were suddenly ejected, and
the products hit a group of people, injuring some of them. The proximal
deposit formed a continuous mantle of ash, lapilli and decimetric-sized
bombs, and the ballistic material reached up to 200 meters away from the
lava edge. A total deposit mass of 7.1 ± 0.8 × 104 kg was estimated,
corresponding to a lava volume removed by the explosion of 32.0 ± 3.6
m3. Textural and morphological data on the ejected clasts were used to
constrain a model of lava-snow interaction. Results suggest that the
mechanism responsible for the explosions was the progressive pressure
build-up due to vapor accumulation under the lava flow, while no
evidence was found for the occurrence of fuel-coolant interaction
processes driving the explosions. Although these low-intensity
explosions are not too frequent, the collected data represent a unique
dataset which provides useful information on the involved processes and
the associated hazard, but also on possible measures of mitigation to
prevent potentially dramatic accidents at volcanoes like Etna, recording
up to thousands of visitors per day.
Multi-fractional fuzzy programming for sustainable agricultural multi-cropping bi-seasonal planning
Authors: Modibbo Umar
Published: December 2022

The agricultural production system composes of several conflicting resources
that must be combined to yield the desired product output. However, some
goals are not conflicting in the system; therefore, this study presents a
multi-objective optimization problem using a multi-fractional fuzzy
programming concept. The objective is to optimize the profit ratio to cash
expenditure and production of crops in different seasons under the
restriction of fertilizer, machine, manpower, water consumption, and land
utilization. The proposed model is illustrated with numerical examples for
validation from an agrirean village in northern Nigeria. The result shows
meaningful achievements and improvement in six crops out of the seven crops
for both the dry and rainy seasons. Thus the concept is recommended for
decision-makers for proper planning and productive yield in the agricultural
industry for ensuring food security and the global sustainable developments.

Post-limit bearing capacity of buckled steel structures frame elements
Authors:   Saint Petersburg State University of Architecture and Civil Engineering, Belyy G. I. , Garipov A. I. ,   Saint Petersburg State University of Architecture and Civil Engineering
Published: December 2022

The «reverse» numerical-analytical method for definition the residual bearing capacity of steel frame elements after buckling is proposed. The method allows to take in consideration the post-critical behavior of plates making up the frame element and large plastic strain overflowing into the self-hardening stage.The solution is carried out by the reverse sequence: it is offered to define values of deformational and non-deformational internal forces by numerical unitless procedure according to a given post-limit deformed state of the most loaded cross-section of an element under compression and bending in one or two planes. Wherein deformational forces are assumed as actually acting forces, taking in consideration geometrical nonlinearity, and non-deformational forces are assumed as fictitious forces, compensating nonlinear material behavior and local buckling. The latter ones are considered to be the result of sequential symmetrical acting of two additional axial fictitious forces with one or two eccentricities on the elastic element. The first fictitious force compensates the initial stage of increase of plastic strains before element buckling, and the second one compensates local buckling and further increase of plastic strains in some part of element span after element buckling. The effect of the geometrical nonlinearity on internal forces is defined by «straight» unitless analytical solution of the problem, considering deformed state, using the elastic model of element compressed by actually acting and fictitious forces with their eccentricities. Evaluated internal forces are used in the reverse solution to define eccentricities of actually acting force on the ends of element. The proposed method has a sufficient accuracy for practical application and allows to reduce by orders the magnitude of computational time compared to numerical methods. The graphs showing how the post-buckling bearing capacity reduction coefficients depends on the value of the normalized strain of the most stressed fiber for some of the cross-sections most widely used in construction practice are presented.

The article proposes a refined Euler-Lagrange mathematical model of the separation process of emulsified petroleum products and solid suspensions from atmospheric surface effluents in coalescent separators with oleophilic polymer corrugated plates. There has been carried out a numerical experiment using a model of the hydrodynamics of flow in the gaps between the plates. The adequacy of the mathematical model is confirmed by experiments on real environment. The calculation results obtained according to the developed mathematical model are the same as those obtained in the course of experiments with an accuracy of ± 9%. The model can be used to calculate coalescent separators designed to purify storm water from dispersed particles and oil droplets.

The article examines the problem of determining the intensity of traffic on streets and roads with irregular transport demand, knowledge of which is necessary for the purposes of design, capital repairs, traffic management, and so on. The impossibility of using existing methods for determining the desired characteristic on the studied transport facilities causes the need to develop mathematical devices within the framework of multifactor forecasting using remote monitoring (satellite observation). In the course of studying the changes in traffic intensity, many factors were taken into consideration, among them there was noted a significant influence of urban population density, the capacity of schools and preschool educational institutions, the availability and capacity of shopping areas. The authors present a model for determining the intensity of traffic flows on streets with irregular transport demand.The results obtained enable collecting data on the primary parameters of the traffic flow in the shortest possible time and without a large amount of resource costs.

Introduction: The E6 and E7 oncoproteins of high-risk Human Papillomavirus (HPV) have crucial roles in cervical cancer pathogenesis by inhibiting p53 and retinoblastoma protein (pRb) which are tumor suppressor genes. Genetic sequence mutations of E6 and E7 oncogenes can affect E6/E7 protein functions that will change E7-pRB interaction. Furthermore, this condition will influence progression cervical cancer progression in several intratypic variants of high-risk HPV type 16.

Methods: A cross-sectional study was conducted from September 2020-September 2021, at the Obstetrics and Gynecology Outpatient Clinic, Prof Dr I. G. N. G. Ngoerah General Hospital. Consecutive sampling was taken by collecting cervical cancer tissue followed by isolation, amplification, and gene sequencing to assess E6 and E7 mutations. The expression of pRb was measured by immunohistochemical staining (IHC).

Results: From 100 cervical cancer subjects, 31 subjects were found HPV16 positive (19 wildtype and 12 mutants). The proportion of E6 and E7 mutants was 25.8% and 12.9% respectively. This study shows that T27C/F9F; A360G/E120E and G371A/R124K variants were found on E6 oncogene mutations, meanwhile, A86C/N29T; A86G/N29S; C229T/R77C and T285C/S95S variants were detected on E7 oncogene mutations. The types of E6 mutations were T27C (16.1%), A360G (6.4%) and G371A (1 subject; 3.2%). In addition, pRb expression was stronger in mutant group than wild-type group 60.5% vs. 53%. There was no correlation between retinoblastoma protein expression and mutations E6/E7 oncogene HPV Type 16 (PR 0.22; 95% CI 0.03-1.6; p value 0.10).

Conclusions: In cervical cancer, there is no significant difference between the expression of retinoblastoma protein in mutant vs wildtype E6 and E7 oncogene HPV16.

Ferrocement adalah jenis dinding tipis beton bertulang umumnya terbuat dari adukan semen hidrolik diperkuat dengan wiremesh. ferrocement sebagai beton mortar dengan perkuatan wiremesh. Elemen ferrocement umumnya lebih ulet karena terdapat penguatan terdistribusi secara seragam. Ferrocement curved slab bisa digunakan sebagai struktur jembatan bentang pendek, atap gedung, dinding penahan tanah dan struktur lainnya. Tujuan dari penelitian ini adalah mengetahui pengaruh kelengkungan pada ferrocement, menganalisis hubungan beban perpindahan dan mengetahui daktilitas ferrocement. Ferrocement curved slab akan ditinjau dengan tiga variasi yaitu dengan diameter 1,5 m dengan sudut 42°, diameter 2,0 m dengan sudut 30° dan diameter 3,0 m dengan sudut 19°. Ukuran benda uji ferrocement curved slab yaitu 1000 x 1000 x 25 mm. Hasil eksperimen menunjukkan beban ferrocement cured slab dengan kelengkungan 42° memiliki “daktilitas” yang lebih besar dibanding ferrocement curved slab dengan kelengkungan 30° dan 19°. menunjukkan bahwa semakin besar sudut kelengkungan maka semakin besar beban yang dibutuhkan untuk membuat retak pertama pada ferrocement curved slab.
