Cadmium (Cd) is considered as phytotoxic in nature, its toxicity on the plant development decrease the antioxidative enzymes activities under stress environment. Castor (Ricinus Communis L.) is a metal tolerant plant and its ability to survive in highly polluted soils. Castor plant exhibited the high level of the Cd stress in the soil and buildup the antioxidants i.e., super oxide dismutase (SOD), peroxidase (POD) and malondialdehyde (MAD) on the top of the ground parts under Cd stress. Castor plant grown in the treated soil for 30 days in various levels of Cd 0, 10, 25 and 50 mg kg-1 soil treatments. Stress caused by heavy metal toxicity effects on reduced the plant growth, biomass, of castor plant respectively under 25- 50 mg kg-1 stress as against to control treatment. Our results indicated that castor significantly enhanced the Cd contents in root, stem and leaves. The POD and SOD enzyme activities were significantly increased 215.30 µmol/g-1 and 53.20 U/g respectively under 50 mg kg-1 stress as against control. While, MAD and chlorophyll content 3.11% and 0.48%, proline content 2.23 to 1.75 µg-1 were decreased under 25 and 50 mg kg-1 Cd stress as against control. According to Pearson’s correlation the our research work exposed strongly positive relationship with root, shoot, proline and malionaldihyde. Although the destructive relationship was demonstrated by PoD and SOD enzyme activities. Hence, this study recommended that castor can grow in highly polluted soils for phytoremediation
The Quadruple Image Configurations of Asymptotically Circular Gravitational Lenses
Authors: Falor Chirag , Schechter Paul L. 
Published: September 2022

Abstract
The quadruple image configurations of gravitational lenses with vanishing ellipticity are examined. Even though such lenses asymptotically approach circularity, the configurations are stable if the position of the source relative to the vanishing diamond caustic is held constant. The configurations are the solutions of a quartic equation, an “asymptotically circular lens equation,” parameterized by a single complex quantity. Several alternative parameterizations are examined. Relative magnifications of the images are derived. When a nonvanishing quadrupole, in the form of an external shear (XS), is added to the singular isothermal sphere (SIS), its configurations emerge naturally as stretched and squeezed versions of the circular configurations. And as the SIS+XS model is a good first approximation for most quadruply lensed quasars, their configurations likewise have only 2 + 1 salient dimensions. The asymptotically circular configurations can easily be adapted to the problem of solar system “occultation flashes.”
Constraining the Planet Occurrence Rate around Halo Stars of Potentially Extragalactic Origin

Abstract
The search for planets orbiting other stars has recently expanded to include stars from galaxies outside the Milky Way. With the Transiting Exoplanet Survey Satellite (TESS) and Gaia surveys, photometric and kinematic information can be combined to identify transiting planet candidates of extragalactic origin. Here, 1080 low-luminosity red-giant branch stars observed by Gaia and TESS with kinematics suggesting a high likelihood of extragalactic origin were searched for planet transits. Transit injection-recovery tests were performed to measure the sensitivity of the TESS data and completeness of the transit search. Injected signals of planets larger than Jupiter with orbital periods of 10 days or less were recovered in ≈44% of cases. Although no planet transits were detected in this sample, we find an upper limit on planet occurrence of 0.52% for hot Jupiters, consistent with previous studies of planet occurrence around similar host stars. As stars in the halo tend to be lower metallicity, and short-period giant planet occurrence tends to be strongly correlated with stellar metallicity, we predict that relative to the Galactic disk population, a smaller fraction of halo stars will host planets detectable by transit surveys. Thus, applying the known planet occurrence trends to potential planet detection around halo stars, we predict ≳13,000 stars must be searched with similar cadence and precision as the stars studied here before a detection of a planet of extragalactic origin is likely. This may be possible with future data releases from the TESS and Gaia missions.

Published: September 2022

Abstract
New high-resolution spectra of the eclipsing binary BD+47 378 were obtained on five nights between 2020 and 2021 with the Bohyunsan Observatory Echelle Spectrograph in Korea. We collected the TESS light curve of the system obtained from Sectors 17 to 18, which shows a flat bottom at the secondary eclipse, an O’Connell effect, and oscillation features. From the spectral analysis, the radial velocities (RVs) of the primary and secondary stars were obtained, and the temperature of the brighter and more massive primary component was determined to be 7140 ± 100 K. According to a simultaneous analysis of the double-lined RVs and TESS light curves, the masses and radii of both components are M
1 = 1.69 ± 0.03 M
⊙, M
2 = 0.80 ± 0.02 M
⊙, R
1 = 2.01 ± 0.01 R
⊙, and R
2 = 0.79 ± 0.01 R
⊙, respectively. The primary component of the system is located on the δ Sct and γ Dor instability strips. After subtracting the theoretical light curve from the TESS data, a total of four independent frequencies (5.7235 day−1, 6.2577 day−1, 6.9588 day−1, and 14.7675 day−1) were detected using the multiple frequency analysis. These frequencies are typical of a δ Sct pulsator. The results reveal that BD+47 378 is a detached system consisting of two main-sequence stars with a δ Sct type primary component.

Abstract
We present new observational benchmarks of rapid neutron-capture process (r-process) nucleosynthesis for elements at and between the first (A ∼ 80) and second (A ∼ 130) peaks. Our analysis is based on archival ultraviolet and optical spectroscopy of eight metal-poor stars with Se (Z = 34) or Te (Z = 52) detections, whose r-process enhancement varies by more than a factor of 30 (−0.22 ≤ [Eu/Fe] ≤ +1.32). We calculate ratios among the abundances of Se, Sr through Mo (38 ≤ Z ≤ 42), and Te. These benchmarks may offer a new empirical alternative to the predicted solar system r-process residual pattern. The Te abundances in these stars correlate more closely with the lighter r-process elements than the heavier ones, contradicting and superseding previous findings. The small star-to-star dispersion among the abundances of Se, Sr, Y, Zr, Nb, Mo, and Te (≤0.13 dex, or 26%) matches that observed among the abundances of the lanthanides and third r-process-peak elements. The concept of r-process universality that is recognized among the lanthanide and third-peak elements in r-process-enhanced stars may also apply to Se, Sr, Y, Zr, Nb, Mo, and Te, provided the overall abundances of the lighter r-process elements are scaled independently of the heavier ones. The abundance behavior of the elements Ru through Sn (44 ≤ Z ≤ 50) requires further study. Our results suggest that at least one relatively common source in the early Universe produced a consistent abundance pattern among some elements spanning the first and second r-process peaks.
Assessment of Osteogenesis Enhancement in Rats Using Bone Densitometry: An In Vivo Study
Authors: Hassan Manar Abd Alrazaq , Ajwad Asmaa A. 
Published: September 2022

Background: Human survival depends on the availability of water. Safe drinking water is a fundamental human right as well as a basic need for a good health. At the mineral and organic levels of water composition, exposure to electromagnetic fields can cause considerable changes in the quality of drinking water. As a result, water is more easily absorbed into the cell walls throughout the body, making it better suited for organ growth and development. When drunk on a daily basis, magnetic water causes dramatic changes in bone mineral density and content. Due to the necessity for distinct beam filtering and near-perfect spatial discography of the two attenuations, DXA (DualEnergy X-ray Absorptiometry) was included with general-purpose X-ray systems. In rats that drink magnetized water on a daily basis, the DXA can be used to calculate the weight and area of all head compartments. Objective: By employing a Bone Densitometry scan on the head regions of rats, this study aims to assess the changes in the rat's skull bone measures (area, weight, bone mineral content, and bone mineral density) after feeding the animal with magnetized water. Methods: This study involved thirty adult male rats (6 weeks old). For 30 days, 15 rats were given a magnetized water to drink and used as experimental animals. For comparison purposes, the remaining 15 rats were given regular water for 30 days. After the experimental procedure was done, each rat's head was scanned with a DXA to determine bone weight, area, bone mineral content, and bone mineral density. Before drinking water, each rat in both the experimental and control groups was examined. The head of each rate was scanned using a DXA to get the values of bone: weight, area, mineral density, and mineral content after 30 days of consuming magnetized water. The four bone measures were statistically compared in the experimental and control rats, p-values below 0.05 were considered significant. Results: Comparing to control rats, experimental rats showed a significant increase in the bone’s weight and area of the skull (p<0.05, Wilcoxon test). Bone marrow content and bone marrow density enhanced significantly as well in experimental rats after drinking the magnetized water for 30 days. Conclusions: Drinking water that has been subjected to electromagnetic fields for 30 days can improve bone marrow content and density in rats. Drinking magnetized water also has a substantial impact on bone mass and area.
Off‐grid direction‐of‐arrival estimation for wideband noncircular sources
Authors: Zhang Xiaoyu , Tao Haihong , Fang Ziye , Xie Jian 
Published: September 2022

AbstractResearchers have recently shown an increased interest in estimating the direction‐of‐arrival (DOA) of wideband noncircular sources, but existing studies have been restricted to subspace‐based methods. An off‐grid sparse recovery‐based algorithm is proposed in this paper to improve the accuracy of existing algorithms in low signal‐to‐noise ratio situations. The covariance and pseudo covariance matrices can be jointly represented subject to block sparsity constraints by taking advantage of the joint sparsity between signal components and bias. Furthermore, the estimation problem is transformed into a single measurement vector problem utilizing the focused operation, resulting in a significant reduction in computational complexity. The proposed algorithm's error threshold and the Cramer–Rao bound for wideband noncircular DOA estimation are deduced in detail. The proposed algorithm's effectiveness and feasibility are demonstrated by simulation results.
Influence of Modern Sociocultural Situation on Axiosphere of Residents of Karelian Border
Authors: Suvorova Irina M. , Kabanova Liliya I. 
Published: September 2022

The article analyzes the problem of the specifics of the quality of life and value orientations of residents of the border Kalevala district of the Republic of Karelia. The retrospective aspect of the study is due to the tragic history of the separation of one people (northern Karelians) in the territory of two neighboring states (Finland and Russia) due to political events and decisions of the past. The historically established isolation (geographical and mental) of Kalevalians is also relevant in modern life. Therefore, the main goal of the study was to determine the degree of influence of socio-cultural factors on the quality of life and axiological dominants of local residents. The analysis of the modern sociocultural situation on the territory of the Kalevala National District was carried out during the complex scientific expedition “Kalevala-2021” and during the cameral processing of the results of field work. In the study a comprehensive methodology of humanities was used, as well as authoritative axiological and psychological methods. As a result of the validation axiological study, specific value dominants of Kalevals were identified, different from the “general cultural profile” of Schwartz, which coincided with the results of a psychological study of “existential fulfillment” and the quality of life of respondents. In sum, the authors of the article identified sociocultural factors that determine the axiological preferences and quality of life of Kalevalians in a modern situation aggravated by pandemic conditions. The article is recommended to specialists in philosophy, cultural studies, sociology and history.

Published: September 2022

Anaemia constitutes a serious health problem in many tropical countries including Nigeria because of the high prevalence of malaria and other parasitic infections which possibly leads to a decrease in hemoglobin. Fluted pumpkin has been reported to be very good in building the constituents of the blood and also replacing them. This study investigated the effects of the methanolic leaves extract of fluted pumpkin on some hematological parameters in 2, 4-dinitrophenylhydrazine-induced anaemic rats. Thirty Wister rats of both sexes were separated into five groups of six rats each. Group 1 serves as normal control, while groups 2-5 were induced with anaemia using 40mg/kg body weight of 2,4- dinitrophenylhydrazine. Group 2 serves as the negative control without treatment, group 3 were given 20 mg/kg (b.w) of standard hematinic drug astymin, and group 4 and 5 were administered with 200 and 400 mg/kg w/w methanolic leaves extract of Telfairia occidentals respectively. All rats were fed with grower’s mash and water ad libitum for 21 days. The rats were sacrificed and blood samples were collected for hematological analysis. All analysis was done using standard methods. The result of this study demonstrated that oral administration of 200 mg/kg and 400mg/kg of the extract increased the haematological parameters under investigation. A significant (p<0.05) increase in haematinic activity was observed in group 3 and 5, and it was concluded that methanolic leaves extract of fluted pumpkin could be effective in ameliorating anaemia.

Abstract
This study aimed to detect the presence of urinary schistosomiasis, the associated risk factors and its impact on blood parameters among Almajiris in two selected rural communities of Kaduna State. Urine samples were collected from 193 Almajiri subjects and processed by sedimentation method and examined under the microscope. Blood samples were also collected from the subjects and processed using SWELAB auto analyser for full blood count. A well-structured knowledge, attitude and practice (KAP) questionnaire was administered to the subjects and used to obtain demographic and other associated risk factors. The overall prevalence of urinary schistosomiasis in the 2 study areas was 16.1%. Bomo recorded 17.5% while Rafin Guza recorded 22.9% prevalence respectively. Subjects in the age-group 11-16 years had a higher prevalence of 33% (p<0.05). Among the risks factors assessed, subjects that visit the stream for swimming and used well water recorded a higher prevalence of (33.7%) and (17.2%) respectively (p<0.05). Awareness about the disease revealed higher prevalence (p<0.05). Prevalence of the infection among the subjects was also found to be significantly associated with White blood cell (WBC) count, Lymphocyte and monocyte count (p<0.05). The present study identified the study areas to represent moderate–risk community for urinary schistosomiasis. The study advocates the use of mass treatment with Praziquantel to help in reducing the infection level and help to control transmission of the disease.
