Published: November 2023

The increasing number of industries and poor treatment of waste will damage environmental health, including agricultural land. Agricultural products from contaminated soil may contain hazardous heavy metals such as chromium which can be harmful to human health if consumed. Examination and determination of chromium critical level in paddy soil are required to evaluate the threshold of heavy metals to disable to distribute into paddy plants. This study aims to obtain the critical level of chromium in light and heavy textured soils with paddy as a plant indicator. The pot experiment was carried out at the greenhouse using a completely randomized design with two factors are heavy metal concentration (Cr) and soil texture (A) and five times repeated. The chromium adsorption test uses the Langmuir approach method. Chromium sorption in heavy-textured soil is higher than in light-textured soil. The maximum sorption of chromium metal in light-textured soil is 87.719 mg kg-1, while in heavy-textured soil is 204.082 mg kg-1. Total chromium in the soil decreases after harvest and reduces rice yields. The critical level of light-textured soil chromium in rice was 0.861 mg kg-1, while the critical level for heavy-textured soil Chromium in rice was 1.012 mg kg-1.

Identifying 1-rectifiable measures in Carnot groups
Authors: Badger Matthew , Li Sean , Zimmerman Scott 
Published: November 2023

AbstractWe continue to develop a program in geometric measure theory that seeks to identify how measures in a space interact with canonical families of sets in the space. In particular, extending a theorem of M. Badger and R. Schul in Euclidean space, for an arbitrarylocally finite Borel measurein an arbitraryCarnot group, we develop tests that identify the part of the measure that is carried by rectifiable curves and the part of the measure that is singular to rectifiable curves. Our main result is entwined with an extension ofanalyst’s traveling salesman theorem, which characterizes the subsets of rectifiable curves inR2{{\mathbb{R}}}^{2}(P. W. Jones,Rectifiable sets and the traveling salesman problem, Invent. Math.102(1990), no. 1, 1–15), inRn{{\mathbb{R}}}^{n}(K. Okikiolu,Characterization of subsets of rectifiable curves inRn{{\bf{R}}}^{n}, J. London Math. Soc. (2)46(1992), no. 2, 336–348), or in an arbitrary Carnot group (S. Li) in terms of local geometric least-squares data calledJones’β\beta-numbers. In a secondary result, we implement the Garnett-Killip-Schul construction of a doubling measure inRn{{\mathbb{R}}}^{n}that charges a rectifiable curve in an arbitrarycomplete, doubling, locally quasiconvex metric space.

Abstract
By analyzing Lukas Rietzschel’s novel Mit der Faust in die Welt schlagen (2018) and Nino (f.k.a. Paula) Bulling’s Comic Im Land der Frühaufsteher (2012), this article explores contemporary portrayals of “East German rural space” against the backdrop of current discourses on Germany’s postmigrant condition. Marginalized on a political, economic and symbolic level and construed as the “Other” of German majority society in mainstream media, the “rural East” has recently been discovered by artists as a medium to reflect on urbanormative and (post-)colonial structures of representation that shape the debate and discursive construction process of postmigrant realities. In order to further illuminate this unique position and potential of East German rural space in art and postmigrant discourse, this paper will explore issues of migration, belonging, and (East German) identity in the abovementioned works through the lens of postcolonial theory.
An Exploration of “Shadow Play”: An Analysis of the Origin of Chinese Film Aesthetics
Authors: Leilei Jia 
Published: November 2023

Abstract
Shadow play is the collective name of different forms of art performance such as “shadow puppets” (皮影戏, Piyingxi), “puppet play” (傀儡戏, Kuileixi), and so on. It is a folk art taught through practices and oral traditions, “creating shadows with light”, and came into being over two millennia ago. It emerged in different forms at different times and across different regions and cultures, thus the phrase can connote slightly different art forms depending on cultural context. Chinese people later used “shadow play” to refer to films introduced to China. Such usage not only addresses the connections between film and opera, but highlights how film inherited traditions of shadow play – telling stories through shadows.

Abstract
The pharmaceutical proprieties of the 2,6-dimethylpiperazine-1,4-diium oxalate oxalic acid compound have been studied and the relevant drug design has been considered. The investigated organic compound with formula (2,6-(CH3)C4H10N2)2(C2O4)2·H2C2O4 (2DPOA) has been synthesized by slow evaporation technique at room temperature of a molar ratio 3:2 mix of oxalic acid and 2,6-dimethylpiperazine. Then 2DPOA has been characterized by IR, 13C NMR, UV–visible and the DFT calculation at the B3LYP level of theory has been made. The molecular structure and parameters (bond angles and lengths) of the molecule have been optimized using the Gaussian 09 software and compared with the XRD data. The atoms-in-molecules (AIM), electron localization function (ELF), and localized orbital locator (LOL) methods have been utilized to determine the types and nature of noncovalent interactions present within the 2DPOA molecule. These methods offer insights into the characteristics and behavior of these interactions. Furthermore, the presence of these interactions has been confirmed through the Hirshfeld Surface (HS) and reduced density gradient (RDG) analysis. The NBO analysis is employed to assess the charge exchange occurring within the studied compound. The molecular reactive sites have been examined using the molecular potential surface and Mulliken atomic charges. The energy gap between HOMO–LUMO and chemical properties of 2DPOA have been determined within the frontier molecular orbital theory. The UV–Vis spectrum of the 2DPOA molecule has been recorded and examined. The calculated and experimental infrared absorption and nuclear magnetic resonance spectra of 2DPOA molecule have been investigated. Finally, the molecular docking simulation has been used to find novel inhibitors and drugs for the cancer and epilepsy disease treatment.

AbstractEfficient treatment of acute myeloid leukemia (AML) patients remains a challenge despite recent therapeutic advances. Here, using a CRISPRi screen targeting chromatin factors, we identified the nucleosome‐remodeling factor (NURF) subunit BPTF as an essential regulator of AML cell survival. We demonstrate that BPTF forms an alternative NURF chromatin remodeling complex with SMARCA5 and BAP18, which regulates the accessibility of a large set of insulator regions in leukemic cells. This ensures efficient CTCF binding and boundary formation between topologically associated domains that is essential for maintaining the leukemic transcriptional programs. We also demonstrate that the well‐studied PHD2‐BROMO chromatin reader domains of BPTF, while contributing to complex recruitment to chromatin, are dispensable for leukemic cell growth. Taken together, our results uncover how the alternative NURF complex contributes to leukemia and provide a rationale for its targeting in AML.

Published: November 2023

Цифровий розвиток все більше охоплює сфери суспільного життя, а в демократично розвинених країнах може стати головним фактором не лише економічного, а й соціального зростання, зокрема, інфраструктури, цифрової грамотності населення, електронної демократії, що призводить до трансформації суспільних відносин. Завдяки використанню сучасних цифрових технологій можемо спостерігати якісні зміни у взаємодії органів державної влади з громадянами та бізнесом у сфері культури, освіти, охорони здоров’я тощо. Рівень запровадження цифровізації та електронного врядування також впливають на реформування державного управління в публічне управління, серед яких доцільно виокремити цифрову трансформацію, поглиблення фокусу на забезпеченні прозорості та підзвітності органів влади, зміцнення співпраці та партнерства, визнання та підтримку багатовекторності публічного управління для досягнення Цілей сталого розвитку. Саме тому увага науковців зосереджена на вдосконаленні цифрового розвитку держави та суспільства шляхом впровадження різноманітних інновацій та технологій задля реалізації державної політики у забезпеченні високого рівня електронної демократії.
Тенденції до зростання цифрової трансформації та електронного врядування в Україні спостерігаються не лише на місцевому та національному рівнях, вони стають характерними і для наднаціонального рівня. Однією з причин є вимушене поширення міграційного руху нашими співвітчизниками, використання ними діючих електронних послуг для полегшення адаптаційного періоду в еміграції, систематизація знань про традиції країн, в яких вони вимушені тимчасово проживати, їх культуру, традиції, когнітивний підхід у вивченні іноземних мов.
В Україні дослідження цифрової трансформації та електронного врядування є важливою складовою забезпечення електронної демократії. Це пояснюється тим, що вони можуть створити в Україні передумови для запобігання або мінімізації корупційних негативних наслідків в державному управлінні, існуючих та прогнозованих ризиків і загроз.

AbstractBackgroundSystemic and organ-specific oxidative stress triggered by hypoxia is suggested to play a key role in germ cell apoptosis and DNA damage. This study was designed to investigate the impact of chronic intermittent hypoxia (CIH) on female fertility and evaluate the potential antioxidant effect of L-arginine (L-Arg) supplementation.MethodsAdult female rats were allocated into three groups: controls (normoxic), hypoxic and hypoxic supplemented with L-Arg. After 12 weeks; hematocrit value was determined, body weight (BW) and ovarian weight were measured for the calculation of the gonado-somatic index. Plasma levels of luteinizing hormone (LH) and progesterone were estimated. Ovarian tissue malondialdehyde (MDA) and catalase were assessed, and caspase-3 enzyme expression was detected by immunohistochemistry.ResultsCompared to controls, CIH resulted in increased oxidative stress in the ovarian tissue, decreased ovarian weight, and increased frequency of irregular cycles and higher plasma level of LH in rats with either regular or irregular ovarian cycles. Histological examination of ovarian sections revealed areas of degeneration, atretic follicles, interstitial edema, congested vessels and inflammatory cell infiltration. Immunohistochemistry confirmed the presence of apoptosis by increased caspase-3 expression. Hypoxic rats pre-treated with L-Arg showed increased BW and ovarian weight, decreased ovarian tissue MDA and plasma LH accompanied by a lower incidence of irregular cycles and mortality. The histological picture was improved and caspase-3 expression was reduced.ConclusionOxidative stress caused by CIH is detrimental to the structure and function of the corpus luteum with an increased risk of reduced fertility. L-Arg supplementation increases antioxidant capacity and improves hypoxia-induced fertility disorders.
