This study aims to determine the effect of Benson's relaxation spiritual therapy on the anxiety of mothers before Cesarean section at RSIA Sitti Khadijah 1 Muhammadiyah Branch, Makassar. The research design used in this study is a Quasi Experiment design with a Non-Equivalent control group Pretest and Posttest method. Sampling was determined using Purposive Sampling based on inclusion and exclusion criteria with a sample size of 58 respondents. The statistical test used was the paired sample T test with a significance α < 0.005. The results of anxiety before the provision of Benson's relaxation therapy showed mild anxiety in 30%, moderate in 61.9%, and severe in 6.9%. After the provision of Benson's relaxation therapy, anxiety levels changed to moderate in 20.6%, mild in 68.8%, and no anxiety in 10.3% in mothers preSC. The research results show that there is an effect of Benson's spiritual relaxation therapy on anxiety in mothers preCesarean Section, with the statistical analysis using the paired T-test at a 95% confidence level showing a value of ρ= 0.000 < 0.005. The conclusion of this study is that Benson's spiritual relaxation therapy has an effect on anxiety in mothers preCesarean Section at RSIA Sitti Khadijah 1 Muhammadiyah Branch Makassar. The recommendation is for nurses and other healthcare providers to implement Benson's spiritual relaxation therapy as part of the non-pharmacological management in addressing anxiety in patients undergoing pre-operative Cesarean Section.
DFIG Soft-Sensor and its Applications

Field: Engineering (Physical Sciences)

The rotor speed measurement of doubly fed induction generator (DFIG) is very important to its control system design, but many problems may arise when applying traditional speed sensor. So, it is necessary to study the speed-sensorless measuring technique. Firstly, a novel speed measuring method based on soft-sensor theory is proposed in this paper. Secondly, the mathematical model of DFIG is given, and the soft-measuring method of dq-axis rotor current components that can't be directly measured are discussed. Thirdly, a soft-sensor of DFIG based on stator voltage oriented control strategy is constructed. Then, the speed observer and the speed-sensorless vector control strategy based on the soft-sensor are proposed. Finally, the simulation is performed on the MATLAB/Sim Power Systems, and the results demonstrate the validity of the proposed method.
Effect of calcination temperature on properties of waste alkaline battery-based catalysts for deep oxidation of toluene and o-xylene

Field: Chemical Engineering (Physical Sciences)

To evaluate waste alkaline battery (WB) as a catalyst for deep oxidation of toluene and o-xylene, we investigated how calcination temperature influenced the catalytic activity of WB-based catalyst for catalyst preparation. Physicochemical properties of WB-based catalysts were characterized by BET (Brunauer Emmett Teller) analysis, XRD (X-ray diffraction), SEM/EDX (scanning electron microscope/energy dispersive X-ray), TGA/DTA (thermo gravimetric analysis/differential thermal analysis), and H 2 -TPR (hydrogen temperature programmed reduction). Major elements of WB-based catalysts were carbon, manganese, zinc, and iron. The catalytic activity of WB-based catalyst was significantly influenced by calcination temperatures ranging from 300 °C–600°C. An increase calcination temperature resulted in a significant decrease in the BET surface area and concentrations of surface carbon and chlorine of the WB-based catalyst, while levels of other components increased. The average pore diameter of the WB-based catalyst calcined at 400 °C (WB (400) catalyst) was the smallest. The concentrations of manganese and iron in WB (400) catalyst were the highest, while those of manganese and iron in the WB-based catalyst calcined at 300 °C (WB (300) catalyst) were the lowest. Therefore, a good performance of WB (400) catalyst was likely due to its higher concentrations of manganese and iron and smaller pore size. When GHSV (gas hourly space velocity) was 40,000 h −1 , toluene and o-xylene were completely oxidized on WB (400) catalyst at 430 °C and 440 °C, respectively.
A Study of Voiced Alveolar and Palato-alveolar Fricative Production by Korean Learners of English

Field: Arts and Humanities (Social Sciences)

This study explores the production of voiced alveolar and palato-alveolar fricatives by Korean learners of English. A production experiment of minimal pairs with /z, з/ was conducted with Korean learners of English and native English speakers. The results indicated Korean learners' use of acoustic cues were different from that of native English speakers in their discrimination of minimal pairs. In one pair, Korean learners of English did not make distinctions at all. Segmental error patterns of Korean learners of English attested a preference of one pattern over the other: vowel insertion or affrication.

Vitamin D and Platelets: A Menacing Duo in COVID-19 and Potential Relation to Bone Remodeling

Field: Medicine (Health Sciences)

Global data correlate severe vitamin D deficiency with COVID-19-associated coagulopathy, further suggesting the presence of a hypercoagulable state in severe COVID-19 patients, which could promote thrombosis in the lungs and in other organs. The feedback loop between COVID-19-associated coagulopathy and vitamin D also involves platelets (PLTs), since vitamin D deficiency stimulates PLT activation and aggregation and increases fibrinolysis and thrombosis. Vitamin D and PLTs share and play specific roles not only in coagulation and thrombosis but also during inflammation, endothelial dysfunction, and immune response. Additionally, another ‘fil rouge’ between vitamin D and PLTs is represented by their role in mineral metabolism and bone health, since vitamin D deficiency, low PLT count, and altered PLT-related parameters are linked to abnormal bone remodeling in certain pathological conditions, such as osteoporosis (OP). Hence, it is possible to speculate that severe COVID-19 patients are characterized by the presence of several predisposing factors to bone fragility and OP that may be monitored to avoid potential complications. Here, we hypothesize different pervasive actions of vitamin D and PLT association in COVID-19, also allowing for potential preliminary information on bone health status during COVID-19 infection.
Modified Landweber tterations in a multilevel setting applied to the determination of nonlinear material parameters in piezoelectricity

Field: Mathematics (Physical Sciences)

Abstract An efficient solution of the inverse problem of identifying nonlinear dependencies in hyperbolic systems of PDEs, here piezoelectric material parameter curves, is the aim of this work. The dominant material tensor entries in the coupled field equations which describe the electromechanical interplay are approximated by functions depending on the physical field quantities electric field or mechanical stress. In order to solve this nonlinear and ill‐posed problem of parameter curve identification efficiently, modified Landweber iterations (steepest descent and minimal error) will be studied. A multilevel approach is expedient due to the discretization of the unknown parameter curves and high computational efforts solving the forward problem (transient, nonlinear FEM computations). Theoretical investigations concerning convergence and regularization properties of the methods in a multilevel scenario will be presented, along with numerical results from an example in piezoelectricity.

Exploration of the Role of the C-Terminal Domain of Human DNA Topoisomerase IIα in Catalytic Activity

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Human topoisomerase IIα (TOP2A) is a vital nuclear enzyme involved in resolving knots and tangles in DNA during replication and cell division. TOP2A is a homodimer with a symmetrical, multidomain structure. While the N-terminal and core regions of the protein are well-studied, the C-terminal domain is poorly understood but is involved in enzyme regulation and is predicted to be intrinsically disordered. In addition, it appears to be a major region of post-translational modification and includes several Ser and Thr residues, many of which have not been studied for biochemical effects. Therefore, we generated a series of human TOP2A mutants where we changed specific Ser and Thr residues in the C-terminal domain to Ala, Gly, or Ile residues. We designed, purified, and examined 11 mutant TOP2A enzymes. The amino acid changes were made between positions 1272 and 1525 with 1-7 residues changed per mutant. Several mutants displayed increased levels of DNA cleavage without displaying any change in plasmid DNA relaxation or DNA binding. For example, mutations in the regions 1272-1279, 1324-1343, 1351-1365, and 1374-1377 produced 2-3 times more DNA cleavage in the presence of etoposide than wild-type TOP2A. Further, several mutants displayed changes in relaxation and/or decatenation activity. Together, these results support previous findings that the C-terminal domain of TOP2A influences catalytic activity and interacts with the substrate DNA. Furthermore, we hypothesize that it may be possible to regulate the enzyme by targeting positions in the C-terminal domain. Because the C-terminal domain differs between the two human TOP2 isoforms, this strategy may provide a means for selectively targeting TOP2A for therapeutic inhibition. Additional studies are warranted to explore these results in more detail.
Context-based learning and metacognitive prompts for enhancing scientific text comprehension

Field: Arts and Humanities (Social Sciences)

Context-based learning (CBL), promoting students' scientific text comprehension, and fostering metacognitive skills, plays an important role in science education. Our study involves CBL through comprehension and analysis of adapted scientific articles. We developed a module which integrates metacognitive prompts for guiding students to monitor their understanding and improve their scientific text comprehension. We investigated the effect of these metacognitive prompts on scientific text comprehension as part of CBL in chemistry. About 670 high school chemistry students were randomly divided into three groups exposed to high- and low-intensity CBL. One of the high-intensity groups was also exposed to metacognitive prompts. Research tools included pre- and post-questionnaires aimed at measuring students' conceptual chemistry understanding and metacognitive knowledge in the context of reading strategies, before and after exposure to the CBL. Chemistry understanding was reflected by students' ability to identify the main subject of the adapted article and by explaining concepts both textually and visually. We found that high-intensity CBL combined with metacognitive prompts improved students' chemistry understanding of the adapted scientific articles and the ability to regulate their learning. Our study establishes that reading context-based adapted scientific articles advances students' conceptual chemistry understanding. These gains are strongly amplified by domain-specific metacognitive prompts.
The Advantages and Limitations of Seeking Sex Online: A Comparison of Reasons Given for Online and Offline Sexual Liaisons by Men Who Have Sex With Men

Field: Psychology (Social Sciences)

Abstract The Internet has developed as a major site for sexual activity, both cybersex and for making contacts for sex in real life (IRL). As part of a major study of HIV-risk behavior on the Internet and IRL, we obtained online responses from 1,017 Latino men who have sex with men (MSM) in the United States. Open-ended questions solicited responses regarding whether respondents preferred to meet sexual partners first IRL (48.4%), on the Internet (31.6%), or "it depends" (20%), and "why?". Data were analyzed by theme, with themes grouped into overarching domains. Data indicate that for those preferring the Internet, themes represented were ease of Internet use, its advantages for people who were shy, and its anonymity, safety, the excitement and opportunity for experimentation of Internet contact, ability to avoid interpersonal contact, and control of visuals and the environment. Reasons for preferring meeting IRL included some of the same themes but with an emphasis on the importance of a "real presence" and the possibility to build a relationship. Where "it depends," key themes were contextual: mood, time, setting, alcohol and drug use, sexual needs and urgency, and relationship intentions. Antagonistic advantages were often noted for cybersex and IRL. These data suggest that motivations for making Internet sexual contact in MSM are complex, depend on the context and nature of the relationship sought, and that the Internet has allowed the development of a class of sexual contacts located between IRL and fantasy.
The Gothic Monster Girl in Toni Morrison’s The Bluest Eye and Margaret Atwood’s “Lusus Naturae”

Field: Arts and Humanities (Social Sciences)

Both Toni Morrison’s The Bluest Eye and Margaret Atwood’s “Lusus Naturae” are anti-Bildungsroman narratives that focus on young women’s rite of passage to womanhood. Morrison’s Pecola and Atwood’s vampire girl are depicted as monsters who are imprisoned within a negative self-image that transforms their world into a nightmare. These girls undergo social and familial victimization, being rejected and ostracized, while their monsterization/dehumanization is emphasized. Morrison and Atwood tackle identity issues such as the female body, femininity, sexuality and (sexual) agency. They expose how the feminine is often seen as the abject within a patriarchal system. They unmask and disclose female victimization and their respective young woman’s identity issues and familial and social problems.
Higher Risk for Obstructive Sleep Apnea in Chronic Treatment-Resistant Depression

Field: Medicine (Health Sciences)

Background: Studies reported the strong link between Obstructive Sleep Apnea (OSA) and Major Depressive Disorder (MDD). However, the risk for OSA in patients with chronic treatment resistant depression (cTRD) is not well documented worldwide. Objectives: We assessed the risk for OSA and associated factors in cTRD patients. Methods: The study recruited 140 Iranian patients with cTRD. All patients completed the Berlin questionnaire, which evaluates the risk of OSA. Additionally, demographic data and history of cardiovascular and metabolic diseases were collected. Pearson's Chi-square test, Fisher's exact test, and independent T-test were used to assess group differences, when appropriate. Results: The study found that 89 of 140 cTRD patients (64%) were at high risk for OSA. Group comparison between cTRD patients (high vs. low risk for OSA) demonstrated that at high risk OSA-cTRD patients had an elevated rate of hypertension, diabetes mellitus, and obesity. Also, age, duration of depression, and duration of treatment were significantly higher in cTRD patients with higher risk compared to those with lower risk OSA" for
Homoclinic chaos in inverted pendula

Field: Mathematics (Physical Sciences)

The existence of homoclinic chaos in the dynamics of two kinds of pendula with linear viscous damping, is proved via Melnikov's method. We consider the classical inverted pendulum, whose pivot can move horizontally on a cart, and the rotating inverted pendulum. Both devices are two degrees of freedom (2-DOF) underactuated systems. We analyze the case when the motion of the actuated part is periodic, with a sufficiently small amplitude.

La dé-moralisation du féminin comme acte de rédemption dans Notturno di donna con ospiti et Medea per strada

Field: Arts and Humanities (Social Sciences)

In these two rewritings of the myth, Medea is a housewife, pregnant with her third child, dedicated to home and family and a foreigner who arrived in Italy with the dream of a better future, imprisoned in a prostitution racket by the man she loves and who becomes the father of her twins. For both Medeas, infanticide becomes an extreme act of liberation from society’s control over women through the ethics of care; a way to de-moralize gender and deconstruct the notion of femininity.
Part 3. Present plate boundary and its evolution in the New Zealand region: Mesozoic-middle tertiary tectonic development of Northern New Zealand

Field: Earth and Planetary Sciences (Physical Sciences)

Northland, that part of New Zealand north of the city of Auckland, is formed in large part from sedimentary rocks belonging to three successive sedimentary associations each of which is accompanied by distinctive igneous rocks. Deposition of the two earlier associations was terminated by brief but widespread periods of deformation at about 90 m.y. and 25 m.y. before present. Deposition in the youngest association ended some 15 m.y. ago, but no clear relationship between this event and deformation has been demonstrated. A brief outline of the rocks that formed during each depositional interval is outlined below and an attempt is made to construct a coherent tectonic history of Northland.
Peculiarities of non-coding RNA functioning in the norm and cerebral ischemia

Field: Neuroscience (Life Sciences)

To date, it has been shown that not only information RNAs, but also various types of non-coding RNA, are involved in the transcriptome reaction in ischemia. In particular, non-coding RNAs can perform important protective functions, acting as competitive endogenous RNAs. They interact with microRNA, which negatively affects the expression of many mRNAs, and neutralize their activity. The particular interest is circular RNAs, which belong to the non-coding RNAs and can most effectively perform the functions of competitive RNAs. Circular RNAs demonstrate the increased resistance to exonucleases and the predominant brain-specific expression pattern, which may indicate their particular importance in this tissue as neuroprotective agents. This review demonstrates the most recent data on the structure and features of the functioning of noncoding RNAs, which indicate the important role of circular RNAs in cell in the norm and ischemia conditions.
Space power system scheduling using an expert system

Field: Computer Science (Physical Sciences)

A most pressing problem in space exploration is timely spacecraft power system sequence generation, which requires the scheduling of a set of loads given a set of resource constraints. This is particularly important after an anomaly or failure. This paper discusses the power scheduling problem and how the software program, Plan-It, can be used as a consultant for scheduling power system activities. Modeling of power activities, human interface, and two of the many strategies used by Plan-It are discussed. Preliminary results showing the development of a conflict-free sequence from an initial sequence with conflicts is presented. It shows that a 4-day schedule can be generated in a matter of a few minutes, which provides sufficient time in many cases to aid the crew in the replanning of loads and generation use following a failure or anomaly.
BASIS FOR SYNTHESIS OF SPIRAL LATTICE QUASICRYSTALS

Field: Mathematics (Physical Sciences)

Observations of the sunflower Helianthus tuberosus reveal the occurrence of both Fibonacci and Lucas numbers of visible spirals (parastichies). This species is multi-headed, allowing a quantitative study of the relative abundance of these two types of phyllotaxis. The florets follow a spiral arrangement. It is remarkable that the Lucas series occurred, almost invariably, in the first-flowering heads of individual plants. The occurrence of left-and right-handed chirality was found to be random, within experimental error, using an appropriate chirality convention. Quantitative crystallographic studies allow the average growth law to be derived (r = al τ−1 ; θ = 2πl/(τ + 1), where a is a constant, l is the seed cell number and τ is the golden mean [Formula: see text]). They also reveal departures from classical theoretical models of phyllotaxis, taking the form of persistent oscillations in both divergence angle and radius. The experimental results are discussed in terms of a new theoretical model for the close-packing of growing discs. Finally, a basis for synthesis of (inorganic) spiral lattice structures is proposed.
Influence of Exogenous Gonadotropin and Sexual Steroids on Ovary Development in Japanese Eel Anguilla japonica

Field: Agricultural and Biological Sciences (Life Sciences)

This study examines Japanese eel ovary responded to the administration of exogenous sexual hormone throughout the reproductive process. In short-term experiment, ovarian follicle exhibited sensitivity to salmon pituitary homogenate (SPH) and sexual steroids (E2 and MT) in the early vitellogenic stages. The apoptotic signals were exclusively localized in the outer theca layer which was detected from in situ TUNEL, furthermore, the appearance of the apoptotic signal in the early vitellogenic stage seems to correlate with a reduction of oocyte numbers in long-term experiment. In long-term experiment, the mean GSI and total oocyte numbers indicated that multiple injections of E2 or MT were not of much benefit to promote the gonadal development of those fish. Despite SPH treatment was an effective and indispensable method to hasten artificially sexual maturation, and the size-frequency distribution indicated that the most developed oocytes of those were growing from the vitellogenic stage to the final maturational phase. However, the treatment of SPH plus E2 failed to promote the ovarian development and exhibited a remarkable reduction of total oocyte numbers. Of interest is the synergistic effect of SPH plus MT revealed that MT, a potent, aromatizable androgen, provides a potential usefulness to participate the process of vitellogenesis when it combines with SPH treatments, furthermore, the synergistic effect actually enhances the survival and synchronous development of ovarian follicle throughout the reproductive process.
