Introduction: Exposure to Pb causes increased apoptosis of ovarian granulosa cells through oxidative stress mechanism. Curcumin has protective effects on reproductive organs, anti-apoptotic, antioxidant in normal cells. Curcumin in innovated nano form can function as an effective anti-apoptosis in ovarian granulosa cells of rats due to PbAc exposure.

Methods: Thirty female rats were divided into 3 groups, the negative control group (the rats receiving distilled water, in each 90 minutes receiving corn oil), positive control group (the rats receiving PbAc of 30 mg/kg BW, in each 90 minutes receiving corn oil), the experimental group, in which the rats receiving PbAc of 30 mg/kg BW, and in each 90 minutes receiving nanocurcumin of 200 mg/kg BW. All groups received treatment orally once a day for 30 days. On day 31 the rats to granulosa cell apoptosis examination using Tunnel method.

Results: Rate of apoptosis was in the positive control group (5.4 ± 0.8%/micro) and the lowest was in the experimental group (1.1 ± 0.5%/micro) and the negative control group (1.2 ± 0.6). The experimental group showed the same p value as the negative control group (p = .095) and different p value (p = .010) from the positive control group. These findings indicated that the innovation of curcumin in nano form at a dose of 200 mg/KgBW reduced apoptosis of rat ovarian granulosa cells due to PbAc exposure.

Conclusion: The innovation of curcumin in nano form has the potential as an effective natural anti-apoptosis in rats ovarian granulosa cells exposed to PbAc.

Published: August 2022

Assessing depth of utility in different soil moisture conditions require good research. Moreover, different soil moisture conditions produce depths that are not the same as one another. The information of underground utility such as depth is very important to avoid damage towards utility during excavation process. Therefore, this study was conducted to assess the depth recorded by the (GPR) equipment in different soil condition in terms of soil moisture. The first objective of this study was to determine the soil moisture level for three different soil conditions. Next, this study evaluated the depth accuracy produced by the GPR equipment with the different soil moisture level such as dry, semi-dry and wet. Different soil moisture conditions were determined by the sampling of the three soil conditions. These samples were taken and tested using speedy soil moisture tester equipment that provided the percentage of soil moisture content. Next, the depth of utility was taken at the three soil moisture conditions and an assessment was made. The shape of hyperbolic on the radargram was generated from the equipment and was used to assess the accuracy of the depth. The information from this study is very useful to underground utility users which can help the development of the country in general. It also benefits the improvement of the preparation quality of underground utility mapping.

In India, 85% of existing buildings are unreinforced masonry and 5-7% are reinforced concrete and 5-7% are traditional buildings. And most buildings do not qualify to resist earthquakes, technically it can be said that they would not be able to resist earthquake loads. In the past, it is seen at the time of the earthquake, millions of lives and the economy of that region is affected. Demolition of ageing building mass is not only harmful to the environment but also it is not viable economically to rebuild all vulnerable buildings. Such buildings are recommended to be retrofitted. Recent earthquakes have demonstrated the need to identify and improve the performance of the existing seismic deficient buildings. For this reason, Seismic vulnerability assessment is considered a part of a better strategy to mitigate the risk and improve the resiliency of the country and its infrastructure. Due to the high volume of building archetypes in our country, for Seismic Vulnerability Assessment at a huge scale, a rapid, simplified method is being adopted that can facilitate the assessment procedure in a lesser computational time period. This paper was primarily engrossed in the analysis of some simplified methods proposed in the literature for assessing the simplified seismic vulnerability. A hypothetical building is analyzed using structural software (Etabs) by Nonlinear Dynamic Analysis Procedure. Using Etabs software, various structural parameters like Story Response Drift, Displacement (max) and Base Shear are considered and discussed. By proper interpretation of the result, a suitable measure to minimize vulnerability and ensure sustainability and cost-effectiveness, retrofitting strategies is recommended.

The development of digital technologies stimulates changes in the field of education, including for students of the educational programs «Digital Journalism» and «Media Technologies». This paper presents the practice of using a database of digital multicultural content in journalism lessons. The relevance of this scientific publication is due to the need to integrate digital technologies into the educational process and the development of students’ skills in working with programming languages. The importance of using such content is described by the modern realities of the educational system, when all members of the academic community are involved in the process of forming national identity within the country and global globalization. Kazakhstan’s conditions demonstrate the penetration of cultures of various ethnic groups, religions, which is the reality of modern teachers and students. The author offers a model for creating a database of digital multicultural content. To do this, the multicultural content of three TV channels and online publications posted on digital services is being studied. The design and structuring of web portals, interfaces, and content are studied. The author conducts quantitative and qualitative research of media materials. A parallel is drawn between the amount of digital content published on television and on Internet resources. Through lexical and compositional analysis, trends and issues of digital multicultural content are identified. The information obtained during the study was organized into a database in the PostgreSQL programming language. As an experiment, the use of the database was tested in journalism lessons when performing exercises and conducting mini-studies. At the end of the training course, a survey of students was conducted on the effectiveness of using databases in the classroom. The students’ answers are analyzed and presented in a generalized form. The methodological methods of working with students described and analyzed in this article are important material for the development of the educational goals of future journalists.
FORECASTING CUSTOMER FUTURE BEHAVIOR IN RETAIL BUSINESS USING MACHINE LEARNING MODELS
Authors:   Kazakh-British Technical University, Kazakhstan, Akhmetbek Shyngys
Published: August 2022

The ability to forecast customers’ future purchases, lifetime value, and churn are fundamental tasks in business management. These tasks become more complicated when the relationship between customers and business is not contractual. Therefore, the application of an appropriate method of customer analysis influences the efficiency of company cost management in interaction with their customers. The purpose of this paper is to compare existing solutions of customer lifetime value prediction and provide a new way to predict the future behavior of customers with consideration of the drawbacks of previous works. The method should have the following properties: use data that is available in any retail business; take into account that markets are constantly changing; be more precise than existing solutions. In this paper, we proposed the method of identifying customer churn provided a way to analyze customer behavior associated with churn or retention. In order to understand why customers churn, we used eleven customer behavioral metrics. The relationship of used metrics with churn was proved using churn cohort analysis. The results of training of logistic regression and neural network on prepared dataset showed that their forecast accuracy is in the healthy range for highly predictable churn. Based on predicted churn probabilities, we calculated the customer lifetime value in the future period. Our research results on customer behavior in the retail business confirm the hypothesis that customers who make many purchases are less likely to churn than customers who make few purchases. The main uniqueness of this work is the way of finding customer churn, as no such data was provided in the initial dataset. In addition, the minimum amount of data that most retail companies have was used. This enables the proposed methodologies to be applied to a large number of retail companies.

Authors: ENER Dilek , ÖZBEY Mehmet Yavuz
Published: August 2022

Aim: Children are vulnerable to home accidents and injuries due to their inability to protect themselves developmentally, and they need the protection of their parents. In the study, it was aimed to investigate the frequency of home accidents of children aged 0-6, the most common types of accidents, and the knowledge levels of mothers on Diagnosing Safety Precautions for Home Accidents.

Material and Method: The study is a cross-sectional and descriptive study and was conducted with 380 parents who applied to the pediatric outpatient clinic in December 2021. The “Scale of Diagnosing the Safety Precautions for Home Accidents of Mothers with 0-6 Age Group Children” was used in the questionnaire form. In the analysis of the relations between the variables, independent groups t-test, the One-way Anova test, the Pearson correlation test, Chi-Square test and Logistic Regression Analyze were applied.

Results: The frequency of children who had home accidents was 11.3%. The most common type of accident is falling. The mean score of the Mothers’ Scale for Diagnosing Safety Measures for Home Accidents was 155.9±15.2. Identification of Safety Precautions scores are higher in mothers who graduated from college, those whose children had a home accident, and those who received first aid knowledge. The most important factors affecting the accident at home are the number of children and the caregiver.

Conclusion: Home accidents, one of the preventable risk factors, are critical health problems. Providing information about all home accidents, especially falls, should be among the priority health targets.
Comparison of the Reliability of the “GÖK Atlas” and the “Gilsanz-Ratib Atlas” in the Determination of Bone Age in Turkish Children
Authors: AYVAT ÖCAL Zeynep , MERAL Orhan
Published: August 2022

Aim: In this study we aimed to evaluate which of the GÖK and GR atlases is more compatible with chronological age in Turkish children aged 5-10 years.

Material and Method: In this study, the wrist radiographs of patients aged 5-10 years who applied to İzmir Bakırçay University Çiğli Training and Research Hospital due to trauma were retrospectively analyzed. A total of 360 wrist radiographs were evaluated. Bone age estimates in both groups were compared with chronological ages.

Results: In the correlation analysis, the prediction rate with 1-difference tolerance is 88.9% in the GR atlas and 76.7% in the GÖK atlas, while both atlases predict 99% correctly with two-difference tolerance. GR Atlas 168 (46.2%) and GÖK Atlas 147 (40.8%) predicted correctly regardless of gender and age. Of the correct estimations, 53.5% in the GR atlas and 57.8% in the GÖK atlas were male cases. İn male age group at the age of 6 and 10, the GR atlas is more successful, at the age of 7, the GÖK Atlas is more successful, and at the age of 5, 8, and 9 the success of both atlases is the same. İn female age group at the age of 5,7, 8, and 10 the GR atlas is more successful, at the age of 6 and 9 the GÖK Atlas is more successful

Conclusion: The GR Atlas was more accurate than the GÖK Atlas. Both the GR Atlas and the GÖK Atlas predicted more accurately in males. Since reference values for bone age can change with environmental and genetic factors all over the world, it is beneficial for all races to create atlas models with multicenter studies in order to establish their own standards.
Idealized 2D Cloud-resolving Simulations for Tidally Locked Habitable Planets

Published: August 2022

Cloud is critical for planetary climate and habitability, but it is also one of the most challenging aspects of studying planets in and beyond the solar system. Here we use a cloud-resolving model (CRM) with high resolution (2 km) in a 2D configuration to simulate the clouds and circulation on tidally locked aquaplanets. We find that the substellar area is covered by deep convective clouds, the nightside is dominated by low-level clouds, and the two are linked by a global-scale Walker circulation. We further find that uniform surface warming causes the substellar cloud width to decrease, but a reduction in the day–night surface temperature contrast or an increase in the longwave radiative cooling rate causes the substellar cloud width to increase. These relationships can be roughly interpreted in accordance with simple thermodynamic theories. Comparing the results between the CRM and the global 3D general circulation model (GCM), we find that they are qualitatively consistent, including the Walker circulation, the substellar clouds, and the responses of the substellar ascending area and strength to changes in the surface temperature or in its zonal contrast. But large quantitative differences exist, such as the magnitude of the cloud water path, the cloud width, and their responses to external forcings. These results increase our confidence in using GCMs to model exoplanetary climates, although large quantitative uncertainties are always likely to exist. Future work is required to use 3D CRMs with realistic radiative transfer and the Coriolis force to examine the clouds and climates of tidally locked planets.
First High-resolution Observations of Interstellar Pickup Ion Mediated Shocks in the Outer Heliosphere

This study reports the first high-time-resolution observations of interstellar pickup ions (PUIs) in the outer heliosphere, including the first high-resolution observations of PUIs mediating shocks collected anywhere. These new data were enabled by a clever flight software reprogramming of the Solar Wind Around Pluto (SWAP) instrument on New Horizons to provide ∼30 minutes resolution as compared to the previous ∼24 hr time resolution. This time resolution is sufficient to resolve the shock structures and quantify the particle heating across these shocks. In the ∼10 months of initial data, we observed seven relatively small shocks, including one reverse shock. We find that the PUIs are preferentially compressed and heated across the shocks, indicating compression ratios from ∼1.2–1.8, with little heating for values less than ∼1.5 and progressively more PUI heating for larger compression ratios. In contrast, core solar wind properties did not show consistent changes across the shocks, indicating that these particles (1) participate little in the large-scale fluid-like interactions of the outer heliosphere’s combined solar wind and PUI plasma and (2) cannot be used to characterize PUI-mediated shocks as prior studies sought to do. All six forward shock crossings showed gradual increases in PUI pressure over shock widths of ∼0.05–0.13 au, which is roughly three decades larger than characteristic particle scales such as the PUI gyroradii. The new high-resolution observations and results described here are important for understanding shocks in the outer heliosphere, the termination shock, and more broadly for PUI-mediated shocks across many astrophysical systems.

Parker Solar Probe (PSP) and SolO data are utilized to investigate magnetic field intermittency in the solar wind (SW). Small-scale intermittency (20−100 d

i
) is observed to radially strengthen when methods relying on higher-order moments are considered (SF
q
; SDK), but no clear trend is observed at larger scales. However, lower-order moment-based methods (e.g., partial variance of increments; PVI) are deemed more appropriate for examining the evolution of the bulk of coherent structures (CSs), PVI ≥ 3. Using PVI, we observe a scale-dependent evolution in the fraction of the data set occupied by CSs, f
PVI≥3. Specifically, regardless of the SW speed, a subtle increase is found in f
PVI≥3 for ℓ = 20 d

i
, in contrast to a more pronounced radial increase in CSs observed at larger scales. Intermittency is investigated in relation to plasma parameters. Though, slower SW speed intervals exhibit higher f
PVI≥6 and higher kurtosis maxima, no statistical differences are observed for f
PVI≥3. Highly Alfvénic intervals display lower levels of intermittency. The anisotropy with respect to the angle between the magnetic field and SW flow, ΘVB is investigated. Intermittency is weaker at ΘVB ≈ 0° and is strengthened at larger angles. Considering the evolution at a constant alignment angle, a weakening of intermittency is observed with increasing advection time of the SW. Our results indicate that the strengthening of intermittency in the inner heliosphere is driven by the increase in comparatively highly intermittent perpendicular intervals sampled by the probes with increasing distance, an effect related directly to the evolution of the Parker spiral.

We report the discovery of 1RXH J082623.6−505741, a 10.4 hr orbital period compact binary. Modeling extensive optical photometry and spectroscopy reveals a ∼0.4 M

Several other cataclysmic variables with similar orbital periods also show unexpectedly low mass-transfer rates, even though selection effects disfavor the discovery of binaries with these properties. This suggests the abundance and evolutionary state of long-period, low mass-transfer rate cataclysmic variables are worthy of additional attention.
Relativistic Magnetic Explosions

Many explosive astrophysical events, like magnetars’ bursts and flares, are magnetically driven. We consider dynamics of such magnetic explosions—relativistic expansion of highly magnetized and highly magnetically overpressurized clouds. The corresponding dynamics are qualitatively different from fluid explosions due to the topological constraint of the conservation of the magnetic flux. Using analytical, relativistic MHD as well as force-free calculations, we find that the creation of a relativistically expanding, causally disconnected flow obeys a threshold condition: it requires sufficiently high initial overpressure and a sufficiently quick decrease of the pressure in the external medium (the preexplosion wind). In the subcritical case the magnetic cloud just “puffs up” and quietly expands with the preflare wind. We also find a compact analytical solution to Prendergast’s problem—expansion of force-free plasma into a vacuum.
Universal Relations for the Increase in the Mass and Radius of a Rotating Neutron Star
Authors: Konstantinou Andreas , Morsink Sharon M.
Published: August 2022

Rotation causes an increase in a neutron star’s mass and equatorial radius. The mass and radius depend sensitively on the unknown equation of state (EOS) of cold, dense matter. However, the increases in mass and radius due to rotation are almost independent of the EOS. The EOS independence leads to the idea of neutron star universality. In this paper, we compute sequences of rotating neutron stars with constant central density. We use a collection of randomly generated EOSs to construct simple correction factors to the mass and radius computed from the equations of hydrostatic equilibrium for nonrotating neutron stars. The correction factors depend only on the nonrotating star’s mass and radius and are almost independent of the EOS. This makes it computationally inexpensive to include observations of rotating neutron stars in EOS inference codes. We also construct a mapping from the measured mass and radius of a rotating neutron star to a corresponding nonrotating star. The mapping makes it possible to construct a zero-spin mass–radius curve if the masses and radii of many neutron stars with different spins are measured. We show that the changes in polar and equatorial radii are symmetric, in that the polar radius shrinks at the same rate in which the equatorial radius grows. This symmetry is related to the observation that the equatorial compactness (the ratio of mass to radius) is almost constant on one of the constant-density sequences.

Searching for periodic non-accelerated signals in the presence of ideal white noise using the fully phase-coherent fast-folding algorithm (FFA) is theoretically established as a more sensitive search method than the fast Fourier transform (FFT) search with incoherent harmonic summing. In this paper, we present a comparison of the performance of an FFA search implementation using RIPTIDE and an FFT search implementation using PRESTO, over a range of signal parameters with white noise and with real telescope noise from the Giant Meterwave Radio Telescope (GMRT) High Resolution Southern Sky (GHRSS) survey with the upgraded GMRT (uGMRT). We find that the FFA search with appropriate de-reddening of the time series performs better than the FFT search with spectral whitening for long-period pulsars under real GHRSS noise conditions. We describe an FFA-search pipeline implemented for the GHRSS survey looking for pulsars over a period of 0.1–100 s and up to a dispersion measure of 500 pc cm−3. We processed GHRSS survey data covering ∼1500 deg2 of the sky with this pipeline. We re-detected 43 known pulsars with a better signal-to-noise ratio in the FFA search than in the FFT search. We also report the discovery of two new pulsars, including a long-period pulsar with a short duty cycle, using this FFA-search pipeline. A population of long-period pulsars with periods of several seconds or higher could help constrain the pulsar death line.

A new orchid species, Hemipilia avisoides, is described from Songpan County, Sichuan Province, China. Morphologically, it is most similar to H. occidensichuanensis (≡ Ponerorchis limprichtii), but H. avisoides can be easily distinguished by its pendulous lateral lip lobes, the oblong middle lip lobe that is smaller than lateral lobes, the dorsal sepal that is concave at each side of central vein below middle, floral bracts that are always shorter than ovary, the leaf that is appressed to substrate and is adaxially green with white and parallel veins, and the solitary sheath at the base of stem. Floral morphology of H. avisoides is also presented by utilizing in vivo micro-CT scanning and 3D visualization.

Raphiocarpus taygiangensis, a new species of Gesneriaceae from Tay Giang District, Quang Nam Province, Central Vietnam, is here described and illustrated. The new species is diagnostic by the combination of its long stem, serrate leaf margin, purple spots, purple longitudinal lines, and glandular short hairs inside corolla. Morphological distinctiveness of the new species from the most similar species, Raphiocarpus axillaris, is discussed. The conservation status of this species is estimated as Vulnerable (VU D2) according to the IUCN Red List Criteria.

Paraphlomis jinggangshanensis (Lamiaceae), a new species from Jiangxi Province, China, is described and illustrated. The new species is morphologically similar to P. intermedia, but can be easily distinguished from the latter by its cordate leaf base (vs. cuneate, decurrent), stem and calyx tube with glandular hairs (vs. short pubescent), and glabrous anthers (vs. ciliate anthers). A phylogenetic analysis, based on ITS regions, suggests that P. jinggangshanensis represents a separate branch in Paraphlomis and is closely related to Clade II. It is currently known only from Jinggangshan National Natural Reserve. Because of its limited distribution and small population size, the species was assessed as Near Threatened (NT) according to the IUCN Red List Categories and Criteria.
