This work shows the integration of geophysical data - gamma-ray spectrometric and magnetometric data (Carmelo et al. 2007; Fianco et al. 2007) - of the airborne geophysical survey Cariris Velho (CPRM 2007) and geologic data. The analysis and interpretation of the geophysics products generated a geophysical model to the area which was correlated it with known geology. The selected area for this study comprises primary gold deposits, inserted in the complex structural system of the Borborema Province, consisting of transcurrents shear zones with dextral and sinistral kinematics (Bizzi et al. 2003). The main purpose of this study was to improve the geological knowledge of the area through the integration of geology, magnetometry, and gamma-ray spectrometry. Results from the present study showed good agreement, when compared with known geology. With the geological/ geophysical integration, we show a concise and direct approach supporting evaluation at the scale of 1:1.000.000.

HowiZombieRethinks the Zombie Paradigm

Field: Arts and Humanities (Social Sciences)

The contemporary zombie genre is known for exploring what the end will look like, with its widespread infection, chaos and violence – all images that resonate in a post-9/11 America. These zombie narratives also speak to a present-day America with their emphasis on diminishing individuality and agency. Unlike early Haitian incarnations of the zombie figure, the modern zombie terrifies because no singular agent possesses the victim's mind. In contrast, the light-hearted CW television show, iZombie (2015–) rethinks the zombie paradigm. Not only does it envision how zombies would manifest in everyday life, without the requisite apocalypse, but it also subverts the antiquated gender politics common to the genre by providing viewers with a female zombie protagonist, Olivia Moore (Rose McIver) who is not only highly functional, but also female and with plenty of agency. Moore, through whose eyes the show is told, absorbs personality traits and memories belonging to the brains she eats, from frat boy to alcoholic, stripper to housewife. This device creates such a cornucopia of roles for McIver to explore that it brings to mind the work of American photographer Cindy Sherman, providing a rare multi-dimensional woman on TV. iZombie also takes the contemporary zombie text's reliance on the trop of infection one step further. This chapter not only examines iZombie's unusual female point of view, but also its portrayal of 'zombie-ness' as a chronic contagious illness with many similarities to HIV.
EEG Microstates in the Study of Attention‐Deficit Hyperactivity Disorder: A Review of Preliminary Evidence

Field: Neuroscience (Life Sciences)

ABSTRACT Attention‐deficit hyperactivity disorder (ADHD) is a neurobiological condition that affects both children and adults. Microstate (MS) analyses, a data‐driven approach that identifies stable patterns in EEG signals, offer valuable insights into the neurophysiological characteristics of ADHD. This review summarizes findings from 13 studies that applied MS analyses to resting‐state and task‐based brain activity in individuals with ADHD. Relevant research articles were retrieved from electronic databases, including PubMed, Google Scholar, Web of Science, PsychInfo, and Scopus. The reviewed studies applied MS analyses to explore brain activity differences in ADHD populations. Resting‐state studies consistently reported alterations in MS organization, with increased duration (MS‐D) and changes in temporal dynamics (MS‐C), potentially reflecting executive dysfunctions and delayed maturation of the default mode network. Additionally, MS B demonstrated promise in distinguishing between ADHD subtypes based on differences in visual network function. Task‐based and event‐related potential (ERP) studies, using paradigms like the continuous performance task (CPT) or Go–NoGo Task, identified MS abnormalities (i.e., N2, P2, P3, CNV) linked to inhibition and attentional resource allocation. Preliminary evidence suggests that MS analyses hold potential for distinguishing individuals with ADHD from control groups. The integration of machine learning techniques holds promise for improving diagnostic accuracy and identifying ADHD subtypes, while MS analyses may also help monitor the effects of stimulant medications like methylphenidate by tracking neurophysiological changes. However, this review highlights the need for more standardized methodologies to enhance the generalizability and replicability of findings. These efforts will ultimately contribute to a deeper understanding of the neurobiological mechanisms that underlie ADHD.
Low-voltage triggering for a pseudospark switch with an auxiliary glow discharge

Field: Engineering (Physical Sciences)

Different electric circuits for triggering the switch with a trigger unit based on an auxiliary glow discharge are discussed. Most attention is concentrated on the recent experimental results on low voltage triggering of the switch and on the mechanisms for the main discharge initiation under the action of the trigger pulse. Due to modifications in the trigger electric circuit, the switch is triggered starting from a voltage of 50 V at a current level in the trigger circuit of 10 mA. With a voltage of 200-250 V and a trigger current of about 0.25 A, the delay time to triggering does not exceed 200 ns.
On-chip test vector generation and downsampling for testing RSFQ circuits

Field: Engineering (Physical Sciences)

Abstract An on-chip high-frequency testing method for rapid single flux quantum circuits is proposed. This method employs test vectors based on pseudo-random sequences created by an on-chip high-frequency clock generator (CG) and a linear feedback shift register with parallel outputs (LSPO). Downsamplers (DSMs) at the outputs of a circuit under test (CUT) decimate the CUT output data so that high-frequency testing can be performed at sufficiently low data rates between the CUT and room-temperature electronics. The proposed testing can continuously test the circuit at high frequency with low-cost instruments. All of the critical subsystems, including LSPO, CG, and DSM, were designed, fabricated, and successfully tested. We validated proper operation at up to 40 GHz, confirming the concept and execution.
The Effect of Temperature on the Forced Response of a Blisk Rotor With Inherent Mistuning

Field: Engineering (Physical Sciences)

Abstract Rotor forced response is a major cause of high-cycle fatigue (HCF) in gas turbine engines. Blade-to-blade variations in natural frequency, known as mistuning, can cause significant variations in the blade-to-blade vibrational response. Individual blade resonant response, primarily the peak frequency, has been used as a ‘fingerprint’ to identify a rotor blisk, and the change in frequency is widely used as a failure detection technique. The frequency data from a forced response investigation of an embedded rotor in the Purdue 3-stage axial compressor research facility is the focus of this work. The forced response of the embedded rotor was measured with both strain gauge and blade tip timing systems. During a repeatability study of the vibrational response, a notable shift in blade peak response frequency was observed. Despite a shift in the peak frequency, the overall shape of the individual blade resonant response curve remained similar, even with the inherent mistuning of the rotor. Factors affecting the frequency and dynamic response were investigated to address this shift. A major difference between these tests was the ambient temperature, which was different on different days and at different times of the day. Material properties are generally temperature-dependent, which has the potential to change natural frequencies. A cyclic symmetric FEM modal analysis showed a modal frequency shift at different temperatures. An analytical study was conducted based on the Fundamental Mistuning Model, considering the effect of temperature. The analytical results correlate well with the experimental results, showing similar blade peak response shifts without significantly changing the blade resonant response curve for the considered temperature range.
Quality of care and satisfaction in mothers of children under 5 years of age who attend a primary health care facility in Lima

Field: Health Professions (Health Sciences)

To identify the relationship between quality of care and satisfaction in mothers of children under 5 years of age who attend the well-child check-up clinic at a primary health care facility in North Lima. The approach adopted was quantitative and the design was correlational-cross-sectional. The population consisted of 420 duly selected informant mothers, to whom the two measurement instruments were applied. There was a significant relationship between the construction of quality of care and satisfaction (p<0.05). Similarly, a significant relationship was found between the dimensions of quality of care (scientific and technical care, human care, and context of care) and satisfaction in all cases (p<0.05). According to the quality of care, the elevated level prevailed (55.7%), followed by medium (24.5%) and low (19.8%). According to satisfaction in mothers, the acceptable value prevailed (52.4%), followed by in process (24.5%) and to improve (23.1%). Finally, there is a relationship between quality of care and waiting time (p<0.05), as well as between satisfaction and waiting time (p<0.05). There was a meaningful relationship between the construction’s quality of care and satisfaction.
Occupational health in the educational context: a descriptive and correlational study

Field: Health Professions (Health Sciences)

The school context represents a significant occupational risk factor for education professionals. Numerous studies highlight that these professionals often show anxiety, depression, stress or burnout, among other health-related issues. Although various sociodemographic variables have been examined for their influence on the development of these symptoms, there is no clear consensus, especially regarding the role of sex, age or type of teaching. The aim of the present study is to assess psychological well-being and personality traits in a sample of education professionals. The sample includes 257 professionals from public and private centers ( M age = 42.48, SD age = 9.8; 72.4% women). The results show significantly higher scores in women in depression, anxiety, stress and psychological burnout. In addition, professionals under 30 years of age showed greater enthusiasm for their work, but also higher stress levels. Regarding the type of teaching, Primary Education professionals showed higher scores related to burnout, while Early Childhood Education professionals reported a significantly higher stress level. Differences in personality were only observed according to the type of teaching, with significantly higher pleasantness scores in the group composed of management and other professionals. These results underscore the vulnerability of education professionals and highlight the need for more extensive research into their occupational health. Evidence-based interventions targeting this population are also essential to address these challenges effectively.
Thermal Inactivation Kinetics and Inhibition Studies of Watermelon (Citrullus vulgaris) Seeds Urease

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

Urease was isolated from the seeds of watermelon (Citrullus vulgaris). The optimum temperature and pH was found to be 50° C and 8.3 respectively. Urease shows no loss in their activity when treated overnight with assay buffer of different pH. Watermelon urease thermal inactivation studies revealed a variation in kinetic pattern at different temperatures. At temperature of 50° C and 60° C, urease shows almost no loss in activity i.e. their stable nature. Thermal inactivation (time dependent) shows biphasic kinetics at 70° C, 80° C and 85° C. Investigation studies strongly support the oligomeric nature of the enzyme. The Km and Vmax of Citrullus vulgaris urease was found to be 10 mM and 142.85 µmole of urea/min/mg of protein. The plot of percent residual activity versus the number of days gave a t1/2 of 70 days for urease stored at 4° C and 16 days for urease that stored at 37° C. The I50 values for Hg2+ and NaCl was found to be 6.9 nM and 240 mM respectively, which shows strong inhibitory nature of Hg2+.
Incidencia de caries en molares primarios después de la colocación de sellantes de ionómero de vidrio

Field: Dentistry (Health Sciences)

The aim of this study was to determine the cumulative incidence (CI) of decay on primary molars treated with glass ionomer (GI) sealants. We hypothesized that GI sealants would decrease caries incidence in primary molars of young children at high caries risk. Data were collected from 56 children aged 1–5 years participating in a community-based sealant program in Immokalee, FL during 2018–2019. Follow-up was planned for 6 months after the initial sealant placement. The mean (±SD) age at sealant placement was 3.57 (±0.66) years. A mean (±SD) of 6.55 (±1.97) sealants were placed per child. There was a mean of 1.29 decayed primary molars per child at the initial visit. A total of 367 Fuji GI sealants were placed on non-carious/non-restored primary molars, or a mean of 6.55 sealants per child. At follow-up, there were 10 newly decayed primary molars among the teeth that had been sealed or a mean of 0.23±0.66 newly decayed teeth per child. The CI of caries among all sealed teeth was 2.7%, with the highest CI on primary mandibular second molars. Sealants were largely effective in preventing caries in primary molars. GI sealants may be an effective prevention strategy for primary molars among young children at high caries risk.
Genomic-Led Potato Breeding for Increasing Genetic Gains: Achievements and Outlook

Field: Agricultural and Biological Sciences (Life Sciences)

Potato is the third most important crop, after rice and wheat, in human diets worldwide. Genetic gains due to its crossbreeding for productivity per se appear to be stagnant in this tetraploid crop. Its genetic enhancement needs to overcome inherent barriers such as ploidy, outcrossing and heterozygosity. Pathogens and pests affect potato because they may infect the entire plant, including stems, leaves and tubers, thus leading to significant tuber yield loss. Hence, host plant resistance breeding remains key for improving the productivity of this crop. This article reviews recent research advances relevant to potato breeding emphasizing genomic resources, methods and tools for genetic analysis, mapping of genes and quantitative trait loci, and genomic prediction of breeding values (or genomic selection) for population improvement. In this regard, association genetics has provided insights onto genetic architecture and inheritance of priority breeding traits, as well as tagging them to DNA markers for their further use as aids for indirect selection. Early research results show the feasibility of genomic selection as a new breeding approach for a tetrasomic polyploid such as potato. This manuscript also highlights the proposed inbred line strategy for producing diploid F1 true potato seed hybrids, and how its use may speed up and increase genetic gains in potato breeding; as well as promoting alleles through gene editing. The paper ends proposing a new interploidy breeding approach considering ploidy manipulations and incorporating genomic selection and gene editing for both population improvement and cultivar development.
Study of Exhaled Nitric Oxide in Subjects with Suspected Obstructive Sleep Apnea: A Pilot Study in Vietnam

Field: Medicine (Health Sciences)

Background and Objective . The concentration of exhaled nitric oxide (eNO), reflecting the activity of inducible NO synthase in airway epithelium, has been found to increase in patients with obstructive sleep apnea (OSA). This study aimed to measure eNO concentration in patients with suspected OSA and to correlate different eNO parameters with clinical and sleep apnea characteristics. Methods . In this cross-sectional study, all patients underwent in-lab overnight polysomnography (PSG) and eNO measurement using a method of multiple flow rates before and after PSG (pre- and post-PSG). Results . According to the result of PSG, 82 persons were divided into two groups: control subjects (n=30;54±14years) and patients with OSA defined as apnea-hypopnea index (AHI) ≥ 5/hour (n=52;53±12years). Body mass index (BMI) and neck and abdomen circumferences of OSA patients were significantly higher than those from control subjects. In OSA group, post-PSG alveolar NO concentration (CANO) (5.3±1.9 ppb) was significantly higher than pre-PSG CANO (4.0±1.7 ppb;P<0.001). Significant correlations have been found between CANO and AHI (P<0.001) and between CANO and nadir SpO 2 (P<0.05). The daytime CANO value of more than 4.1 ppb can be used to screen symptomatic subjects for the presence of OSA with a high specificity of 93.3%. Conclusion . Our findings indicate CANO as a surrogate marker for OSA in persons with suggestive symptoms.
The Effect of Viburnum opulus L. Fruit Extract on Seed Germination and Seedling Growth of Maize (Zea mays L.) Under Salt Stress Conditions

Field: Agricultural and Biological Sciences (Life Sciences)

Guelder rose (Viburnum opulus L.) is recognized as a valuable medicinal and nutritional plant. Traditionally, Viburnum opulus (VO) has been used to treat various health conditions, including coughs, colds, tuberculosis, rheumatic pain, ulcers, gastrointestinal disorders, and renal issues. The beneficial health effects of Viburnum opulus are largely attributed to its antioxidant properties, which have been demonstrated in both in vitro and in vivo studies. However, no research has investigated its specific effects on seed germination, yet. Salt stress is a significant environmental factor that negatively affects plant growth and development. In this study, the effects of Viburnum opulus fruit extract (VO FE) at four different concentrations (125, 250, 500, and 1000 µg/ml) on maize (Zea mays L.) seed germination and seedling growth under 300 mM NaCl (severe salt stress) were investigated. Germination percentage (GP), germination rate index (GRI), germination energy (GE), mean germination time (MGT), seed vigor (SV), shoot weight (SW), shoot length (SL), root weight (RW), root length (RL), and hypocotyl length (HL) were measured to evaluate the effects of VO FE on maize performance. The results revealed that under salt stress conditions, treatments of 500 and 1000 VO FE µg/ml had an adverse effect on germination and growth, while 125 µg/ml VO FE treatment showed no statistically significant improvement compared to salt stress alone. However, the 250 µg/ml VO FE treatment significantly improved germination and growth parameters restricted by salt stress. The 250 µg/ml VO FE treatment increased GP, GRI, GE, and SV by 19.6%, 31.27%, 15.28%, and 32.8%, respectively, while MGT decreased by 7.24% under salt stress. Regarding growth parameters, SFW and SL were increased by 5.69% and 87.5%, respectively, and RFW and RL were increased by 15.5% and 37.4%, respectively. Additionally, HL increased by 18.46% with the treatment of 250 µg/ml VO FE. Based on these findings, this study demonstrates that pretreatment with 250 µg/ml Viburnum opulus fruit extract significantly enhanced seed germination and plant growth in maize and improved tolerance to salt stress, making it a promising approach for mitigating the effects of salinity on crop performance.
“Reformed Theosis?”: A Response to Gannon Murphy

Field: Arts and Humanities (Social Sciences)

Any attempt to reclaim Orthodox aspects of the “great tradition” for contemporary theology is to be applauded. In this light, Gannon Murphy has done the church a real service in stimulating discussion surrounding the compatibility of an Orthodox notion of theosis with contemporary Reformed theology. 1 Having argued the same thing previously, I stand beside Murphy as a brother in arms. 2 There are, however, differing views on how best to incorporate theosis and Reformed thought. In this essay, I point out areas of agreement between Murphy and myself, discuss a number of areas in which I disagree with Murphy's proposal, and finally offer a brief reflection on how I think Reformed theology and a doctrine of theosis are compatible. At the outset I wish to affirm my agreement with Murphy and make it clear that we share much in common despite our disagreements. 3
