Relationship between motivations and dietary behaviours within parent-adolescent dyads: Application of actor-partner interdependence models.

BACKGROUND: Parents play a substantial role in improving adolescent dietary behaviours. OBJECTIVES: To examine the interdependent relationships between motivations (autonomous and emotional motivation) and dietary behaviours (fruit and vegetable [F/V] and junk food and sugar-sweetened beverage [JF/SSB] intake) within parent-adolescent dyads. METHODS: This secondary data analysis was conducted on 1522 parent-adolescent dyads using a cross-sectional Family Life, Activity, Sun, Health, and Eating (FLASHE) study. The ratio of boys to girls among the adolescents was approximately equal, and 74% of the parents were mothers. The adolescents were between 12 and 17 years old, and 85.5% of the parents were between 35 and 59 years old. Parents and adolescents completed an online survey on dietary motivations and behaviours. Actor-partner interdependence models were performed within parent-adolescent dyads. RESULTS: F/V and JF/SSB intake was influenced by parents' or adolescents' autonomous motivation (actor-only pattern), except among adolescents with obesity. A dyadic pattern was found in the relationship between autonomous motivation and F/V and JF/SSB intake, but only among adolescents with normal weight. No relationship was found between F/V and JF/SSB controlled motivation and F/V or JF/SSB intake among adolescents with overweight or obesity. CONCLUSIONS: Autonomous motivation had a significant relationship with F/V and JF/SSB intake for both parents and adolescents, but the association varied depending on the adolescents' weight. Personalized programmes that foster autonomous motivation to change dietary behaviours should be provided based on the adolescents' weight status.

SUN5, a testis-specific nuclear membrane protein, participates in recruitment and export of nuclear mRNA in spermatogenesis.

SUN5, a testis-specific gene, is associated with acephalic spermatozoa syndrome (ASS). Here, we demonstrate that Sun5 is involved in mRNA export. In Sun5-knockout mice ( Sun5 -/-), poly(A) + RNA accumulates in the nuclei of germ cells, leading to reduced sperm counts, decreased sperm motility and disrupted sperm head-to-tail junctions. Additionally, in the GC-2 germ cell line with RNA interference of Sun5, heterogeneous nuclear ribonucleoproteins (hnRNPs) and poly (A) + RNA (mainly mRNA) are retained in the nucleus. Further mechanistic studies reveal that Sun5 interacts with Nxf1 (nuclear RNA export factor 1) and nucleoporin 93 (Nup93). Interference with Nup93 inhibits mRNA export. Treatment with leptomycin B to block the CRM1 pathway indicates that Sun5 regulates mRNA export through an Nxf1-dependent pathway. In Sun5 -/- mice, the binding of Nxf1 and Nup93 decreases due to loss of Sun5 function, and the process of submitting Nxf1-binding mRNPs to Nup93 is inhibited, resulting in abnormal spermatogenesis. Together, these data may elucidate a novel pathway for mRNA export in male germ cells.

It's not just about the sun, it's about a living: Rural older farmers' experience of skin cancer risk and prevention.

OBJECTIVE: To understand rural older farmers' perspectives and attitudes toward skin cancer risk and prevention. DESIGN AND SAMPLE: This study used a grounded theory approach and semi-structured interviews with 12 rural older farmers (farm owners, farmworkers ages 50 years or older) in Washington. Participants' perspectives were explored relative to Health Belief Model constructs. Inductive and deductive analyses were used to generate relevant themes. COREQ guidelines were followed. RESULTS: The findings fit well and extended the Health Belief Model, which was used to arrange key themes identified in relation to skin cancer risk and prevention, specifically participants' perceived barriers to accessing primary care and protection when outdoors, perceived benefits of sun-protective behaviors, perceived hereditary susceptibility to skin cancer, perceived severity of the increased skin cancer risk, and cues to action for skin checks. A new construct of hope was identified to emphasize the importance of establishing emotional, instrumental, and informational support systems for promoting skin cancer prevention. Participants also indicated their hope of raising awareness of skin cancer prevention among all ages. CONCLUSIONS: Findings highlighted the importance of integrating skin cancer prevention services for rural older farmers and across the lifespan. Public health approaches are needed to enhance the awareness of and access to preventive care in these underserved populations.

Triangulation of Hard X-Ray Sources in an X-Class Solar Flare with ASO-S/HXI and Solar Orbiter/STIX.

HXI on ASO-S and STIX onboard Solar Orbiter are the first simultaneously operating solar hard X-ray imaging spectrometers. ASO-S's low Earth orbit and Solar Orbiter's periodic displacement from the Sun-Earth line enables multi-viewpoint solar hard X-ray spectroscopic imaging analysis for the first time. Here, we demonstrate the potential of this new capability by reporting the first results of 3D triangulation of hard X-ray sources in the SOL2023-12-31T21:55 X5 flare. HXI and STIX observed the flare near the east limb with an observer separation angle of 18°. We triangulated the brightest regions within each source, which enabled us to characterise the large-scale hard X-ray geometry of the flare. The footpoints were found to be in the chromosphere within uncertainty, as expected, while the thermal looptop source was centred at an altitude of 15.1 ± 1 Mm. Given the footpoint separation, this implies a more elongated magnetic-loop structure than predicted by a semi-circular model. These results show the strong diagnostic power of joint HXI and STIX observations for understanding the 3D geometry of solar flares. We conclude by discussing the next steps required to fully exploit their potential.

SU(N) symmetry of coherent photons controlled by rotated waveplates.

The coherent state from a laser source has spin and orbital degrees of freedom, which allow an arbitrary superposition state among orthogonal states with varying amplitudes and phases. Here, we theoretically show coherent photons with SU(N) symmetry are characterised by expectation values of angular momentum shown on a hypersphere in SO( N 2 - 1 ) space. To demonstrate expected unitary transformations in experiments, we have constructed generators of transformations in the Lie group simply by combining widely available optical components such as waveplates and vortex lenses. We show a superposition state between twisted and Gaussian states is characterised by the dynamics of the topological charge upon the transformation in SU(3) states. We also realised photonic singlet and triplet states corresponding to SU(4) states, which were projected to SU(2)×SU(2) states upon passing through a rotated polariser.

Dynamic profiling of metabolite changes and health-promoting functions in 'yuling paste' during nine steaming and nine sun-drying processes.

Yuling paste, a traditional Chinese health food derived from longan pulp and American ginseng, undergoes a unique processing method involving nine cycles of steaming and sun-drying. Ultra-high-performance liquid chromatography tandem mass spectrometry combined with widely targeted metabolomics has been used to examine the dynamic change in metabolite profiles through the processing. A total of 758 metabolites were identified. Processing significantly affects metabolite changes, and network pharmacology is subsequently used to explore potential pharmacological ingredients. After processing, the contents of active ingredients such as ginsenoside rh2, oleanolic acid, choline, d-glucose, and D-galacturonic acid were found to increase significantly. These increases can be correlated to the enhancement of five distinct pathways, and the contents of naringenin-7-O-glucoside, adenosine, pantothenic acid, and D-sucrose decreased after the processing, correlating with decreases in two different pathways. This study provides a comprehensive reference and scientific basis for understanding the health benefits associated with this traditional health food.

Science development study for the Atacama Large Aperture Submillimeter Telescope (AtLAST): Solar and stellar observations.

Observations at (sub-)millimeter wavelengths offer a complementary perspective on our Sun and other stars, offering significant insights into both the thermal and magnetic composition of their chromospheres. Despite the fundamental progress in (sub-)millimeter observations of the Sun, some important aspects require diagnostic capabilities that are not offered by existing observatories. In particular, simultaneously observations of the radiation continuum across an extended frequency range would facilitate the mapping of different layers and thus ultimately the 3D structure of the solar atmosphere. Mapping large regions on the Sun or even the whole solar disk at a very high temporal cadence would be crucial for systematically detecting and following the temporal evolution of flares, while synoptic observations, i.e., daily maps, over periods of years would provide an unprecedented view of the solar activity cycle in this wavelength regime. As our Sun is a fundamental reference for studying the atmospheres of active main sequence stars, observing the Sun and other stars with the same instrument would unlock the enormous diagnostic potential for understanding stellar activity and its impact on exoplanets. The Atacama Large Aperture Submillimeter Telescope (AtLAST), a single-dish telescope with 50m aperture proposed to be built in the Atacama desert in Chile, would be able to provide these observational capabilities. Equipped with a large number of detector elements for probing the radiation continuum across a wide frequency range, AtLAST would address a wide range of scientific topics including the thermal structure and heating of the solar chromosphere, flares and prominences, and the solar activity cycle. In this white paper, the key science cases and their technical requirements for AtLAST are discussed.

Observations of our Sun and other stars at wavelengths of around one millimeter, i.e. in the range between infrared and radio waves, present a valuable complementary perspective. Despite significant technological advancements, certain critical aspects necessitate diagnostic capabilities not offered by current observatories. The proposed Atacama Large Aperture Submillimeter Telescope (AtLAST), featuring a 50-meter aperture and slated for construction at a high altitude in Chile's Atacama desert, promises to address these observational needs. Equipped with novel detectors that would cover a wide frequency range, AtLAST could unlock a plethora of scientific studies contributing to a better understanding of our host star. Simultaneous observations over a broad frequency range at rapid succession would enable the imaging of different layers of the Sun, thus elucidating the three-dimensional thermal and magnetic structure of the solar atmosphere and providing important clues for many long-standing central questions such as how the outermost layers of the Sun are heated to very high temperatures, the nature of large-scale structures like prominences, and how flares and coronal mass ejections, i.e. enormous eruptions, are produced. The latter is of particular interest to modern society due to the potentially devastating impact on the technological infrastructure we depend on today. Another unique possibility would be to study the Sun's long-term evolution in this wavelength range, which would yield important insights into its activity cycle. Moreover, the Sun serves as a fundamental reference for other stars as, due to its proximity, it is the only star that can be investigated in such detail. The results for the Sun would therefore have direct implications for understanding other stars and their impact on exoplanets. This article outlines the key scientific objectives and technical requirements for solar observations with AtLAST.

Ultraviolet radiation protection factors of livestock shade cloths for free-range pigs.

BACKGROUND: Protection from solar ultraviolet radiation (UVR) is paramount in light-skinned pig breeds such as Yorkshire or Landrace to avoid sunburn. OBJECTIVES: Determination of the UVR exposure of a pig and the sun protection abilities of shade cloths with different shade rates. ANIMALS: Life-sized plastic model of a Landrace pig. MATERIALS AND METHODS: The model was equipped with 20 UVR meters at various anatomical positions that recorded the erythemal effective solar irradiance. A turntable enabled irradiation from different directions. Solar irradiance was measured in direct sunlight as well as under three shade cloths with different shade rates (50%, 75% and 90%) and a camouflage net. The sun protection factors (SPF) were determined as the ratio of unshaded-to-shaded measurements at the same solar elevation. The exposure ratio to ambient (ERTA) was calculated for each body site with respect to ambient irradiance. It allows determination of when pigs are at risk of sunburn and protection is needed. RESULTS: The calculated ERTA values show that some body parts may receive higher values than ambient UVR. Measurements showed that the SPF of shade cloths depends on textile denseness. Selected shade cloths reached values of 3.5 (shade rate 50%), 4.2 (75%) and 5.8 (90%). Protection by the camouflage net was poor. The highest SPF was gained on body sides where ERTA was highest. CONCLUSIONS AND CLINICAL RELEVANCE: Shade cloths can protect all body sites effectively and vulnerable sites in particular. The results of our study enable an estimation of when pigs are at risk of sunburn and provide quantitative metrics for sun protection. This allows effective prevention of UVR-caused skin damage and secondary disorders.

General Public Awareness Toward Vitamin D Deficiency in Qassim, Saudi Arabia.

Introduction Vitamin D, essential for various bodily functions, exists as D2 and D3, synthesized from plant and animal sources. Deficiency, linked to reduced intake, sun exposure, or metabolic disorders, poses health risks like diabetes and cardiovascular diseases. Management includes fortification, supplements, and individual assessment to avoid toxicity. Our study aimed to assess the public awareness of vitamin D deficiency in Qassim, Saudi Arabia, examining its relationship with sociodemographic factors. Methodology This cross-sectional study was conducted in the Qassim Region, Saudi Arabia, employing convenient non-probability sampling among a population of 375 individuals. Data collection was facilitated through a validated questionnaire, and subsequent coding, data entry, and analysis were executed using IBM SPSS Statistics for Windows, Version 27.0 (Released 2020; IBM Corp., Armonk, NY, USA). Results Our study included 375 adults in Qassim, Saudi Arabia, revealing varying vitamin D deficiency awareness levels. Most were women (n = 204, 54.4%) residing in urban areas (n = 293, 78.1%). At the same time, 77.6% (n = 291) had prior knowledge of vitamin D and fewer practiced habits conducive to its synthesis, with 47.7% (n = 179) including vitamin D-rich foods and 39.2% (n = 147) exposing themselves to sunlight. Family/friends (n = 99, 26.4%) were the primary information source. Participants scored (n = 183, 48.8%) good or high on vitamin D awareness. Education level (p = 0.028), urban residence (p = 0.001), employment status (p = 0.032), and income (p = 0.001) significantly influenced awareness, and gender, age, and marital status showed no significant associations with vitamin D awareness. Conclusion Our study shows that the majority have prior knowledge of vitamin D, yet significant gaps exist in awareness of vitamin D deficiency among adults in Qassim, Saudi Arabia. Education, urban residence, employment, and income were critical determinants of awareness, underscoring the need for targeted educational interventions. There is a need to provide information about vitamin D and its other aspects through various media, such as television and social platforms.

Life history strategy of Tubastraea spp. corals in an upwelling area on the Southwest Atlantic: growth, fecundity, settlement, and recruitment.

Over the past few decades, corals of the genus Tubastraea have spread globally, revealing themselves to be organisms of great invasive capacity. Their constant expansion on the Brazilian coast highlights the need for studies to monitor the invasion process. The growth, fecundity, settlement, and data on the coverage area of three co-occurring Tubastraea species in the 2015-2016 period were related to temperature variation and light irradiance on the rocky shores of Arraial do Cabo, Rio de Janeiro. Hence, this study sought to understand and compare the current invasion scenario and characteristics of the life history strategy of sun coral species based on environmental variables, considering the uniqueness of this upwelling area in the southwestern Atlantic. For that, we evaluate the fecundity, settlement, and growth rates of corals by carrying out comparative studies between species over time and correlating them with the variables temperature and irradiance, according to seasonality. Field growth of colonies was measured every two months during a sample year. Monthly collections were performed to count reproductive oocytes to assess fecundity. Also, quadrats were scrapped from an area near a large patch of sun coral to count newly attached coral larvae and used years later to assess diversity and percentage coverage. Results showed that corals presented greater growth during periods of high thermal amplitude and in months with below-average temperatures. Only Tubastraea sp. had greater growth and polyp increase in areas with higher light incidence, showing a greater increase in total area compared to all the other species analyzed. Despite the observed affinity with high temperatures, settlement rates were also higher during the same periods. Months with low thermal amplitude and higher temperature averages presented high fecundity. While higher water temperature averages showed an affinity with greater coral reproductive activity, growth has been shown to be inversely proportional to reproduction. Our study recorded the most significant coral growth for the region, an increase in niche, high annual reproductive activity, and large area coverage, showing the ongoing adaptation of the invasion process in the region. However, lower temperatures in the region affect these corals' reproductive activity and growth, slowing down the process of introduction into the region. To better understand the advantages of these invasion strategies in the environment, we must understand the relationships between them and the local community that may be acting to slow down this colonization process.

Overview of proficiency testing results for the in vivo determination of sun protection factor.

A sunscreen product is allowed to be marketed if a protection is provided against ultraviolets (UV) including UVA rays and UVB rays expressed by the sun protection factor (SPF). UVB is radiation that is in the region of the ultraviolet spectrum which extends from about 290 to 320 nm in wavelength and that is primarily responsible for sunburn, ageing of the skin, and the development of skin cancer. Thus, since April 2009, the Bureau Interprofessionnel d'Etudes Analytiques (BIPEA) set up a proficiency testing scheme (PTS) for the determination of SPF in vivo of sunscreen products according to ISO 24444 standard [Cosmetics - Sun protection test methods - in vivo determination of the sun protection factor (SPF)] to evaluate the analytical performances of laboratories on these analyses. This PTS gathers twenty-six laboratories around the world with one trial a year. For each test, the statistical treatment of the data is performed according to ISO 13528 standard [Statistical methods for use in proficiency testing by interlaboratory comparison]. The assigned and tolerance values are calculated from the participants' data and the performances of the laboratories are evaluated individually and collectively according to ISO 17043 standard [Conformity assessment - General requirements for proficiency testing]. This paper presents the design of the PT program, its development, and an attentive analysis of laboratories results, which highlight the global performances obtained by laboratories on this type of analysis. The evaluation of the results shows, in fact, a relatively constant dispersion of data since the implementation of the PT program (variability between 10% and 50%).

Un produit solaire peut être commercialisé s'il offre une protection contre les ultraviolets (UV), y compris les rayons UVA et UVB, exprimée par le facteur de protection solaire (FPS). Les UVB sont des rayonnements qui se situent dans la région du spectre ultraviolet dont la longueur d'onde s'étend d'environ 290 à 320 nm et qui sont principalement responsables des coups de soleil, du vieillissement de la peau et du développement du cancer de la peau. Ainsi, depuis avril 2009, le Bureau Interprofessionnel d'Etudes Analytiques (BIPEA) a mis en place un système d'essais d'aptitude pour la détermination du FPS in vivo des produits de protection solaire selon la norme ISO 24444 [Cosmétiques ­ Méthodes d'essai de protection solaire ­ Détermination in vivo du facteur de protection solaire (FPS)] afin d'évaluer les performances analytiques des laboratoires sur ces analyses. Ce programme d'essais d'aptitude regroupe vingt­six laboratoires dans le monde à raison d'un essai par an. Pour chaque essai, le traitement statistique des données est effectué selon la norme ISO 13528 [Méthodes statistiques utilisées dans les essais d'aptitude par comparaison interlaboratoires]. Les valeurs assignées et les valeurs de tolérance sont calculées à partir des données des participants et les performances des laboratoires sont évaluées individuellement et collectivement conformément à la norme ISO 17043 [Évaluation de la conformité ­ Exigences générales concernant la compétence des organisateurs d'essais d'aptitude]. Cet article présente la conception du programme d'essais d'aptitude, son développement, et une analyse attentive des résultats des laboratoires, qui mettent en évidence les performances globales obtenues par les laboratoires sur ce type d'analyse. L'évaluation des résultats montre en effet une dispersion des données relativement constante depuis la mise en place du programme (variabilité entre 10% et 50%).

Design and development of solar parabolic concentrator, closed-loop pressurized hot water for a household baking system - For the case of injera baking in Ethiopia.

A laboratory setup with two axis of manual sun-tracking was designed and built. To get the predicted values for a solar injera stove, a 20-min heating time to prepare it for baking, 3.1 kWh power in the first hour, and 5.8 kWh (with only an 87 percent increase) in the second hour were acquired to bake 9 and 28 injera using electric injera stove, respectively. The temperature distribution on the clay surface was the range of 180 °C-220 °C. Solar injera baking stove was designed and built using the average energy required to bake one injera from an electrical injera stove. The laboratory setup was put to the test, temperatures at the receiver's surface ranging from 315 to 318 °C and an average solar radiation of 1000 W/m2 was obtained on the first test. The injera stove inlet reached a maximum temperature of 180.92 °C with a pressure of 14.5 bars during a pressurized hot water production and circulation test (load test). The surface temperature of the solar injera stove clay plate reached a maximum of 62.69 °C. Temperature of more than 60 °C was maintained on the surface of the solar injera stove plate for nearly 2 h.

Digital Interventions to Modify Skin Cancer Risk Behaviors in a National Sample of Young Adults: Randomized Controlled Trial.

BACKGROUND: Young adults engage in behaviors that place them at risk for skin cancer. Dissemination of digital health promotion interventions via social media is a potentially promising strategy to modify skin cancer risk behaviors by increasing UV radiation (UVR) protection and skin cancer examinations. OBJECTIVE: This study aimed to compare 3 digital interventions designed to modify UVR exposure, sun protection, and skin cancer detection behaviors among young adults at moderate to high risk of skin cancer. METHODS: This study was a hybrid type II effectiveness-implementation randomized controlled trial of 2 active interventions, a digital skin cancer risk reduction intervention (UV4.me [basic]) compared with an enhanced version (UV4.me2 [enhanced]), and an electronic pamphlet (e-pamphlet). Intervention effects were assessed over the course of a year among 1369 US young adults recruited primarily via Facebook and Instagram. Enhancements to encourage intervention engagement and behavior change included more comprehensive goal-setting activities, ongoing proactive messaging related to previously established mediators (eg, self-efficacy) of UVR exposure and protection, embedded incentives for module completion, and ongoing news and video updates. Primary outcome effects assessed via linear regression were UVR exposure and sun protection and protection habits. Secondary outcome effects assessed via logistic regression were skin self-exams, physician skin exams, sunscreen use, indoor tanning, and sunburn. RESULTS: The active interventions increased sun protection (basic: P=.02; enhanced: P<.001) and habitual sun protection (basic: P=.04; enhanced P=.01) compared with the e-pamphlet. The enhanced intervention increased sun protection more than the basic one. Each active intervention increased sunscreen use at the 3-month follow-up (basic: P=.03; enhanced: P=.01) and skin self-exam at 1 year (basic: P=.04; enhanced: P=.004), compared with the e-pamphlet. Other intervention effects and differences between the Basic and Enhanced Intervention effects were nonsignificant. CONCLUSIONS: The active interventions were effective in improving several skin cancer risk and skin cancer prevention behaviors. Compared with the basic intervention, the enhanced intervention added to the improvement in sun protection but not other behaviors. Future analyses will explore intervention engagement (eg, proportion of content reviewed). TRIAL REGISTRATION: ClinicalTrials.gov NCT03313492; http://clinicaltrials.gov/ct2/show/NCT03313492.

Epidemiological investigation of foot-and-mouth disease outbreaks in a Vietnamese bear rescue centre.

Foot-and-mouth disease (FMD) outbreaks affecting Asiatic black bears (Ursus thibetanus) and a Malayan sun bear (Helarctos malayanus) were previously reported in 2011 in two housing facilities at a Vietnamese bear rescue centre. In this study, demographic data of all animals housed in the centre at the time of the outbreaks (n = 79) were collected. Blood samples drawn from 23 bears at different timepoints were tested for FMDV-specific antibodies targeting using a non-structural protein (NSP) ELISA and by virus neutralisation test (VNT). The relationship between seroconversion and clinical signs was explored and epidemic curves and transmission diagrams were generated for each outbreak, where FMD cases were defined as animals showing FMD clinical signs. Outbreak-specific attack rates were 18.75 and 77.77%, with corresponding basic reproduction numbers of 1.11 and 1.92, for the first and second outbreaks, respectively. Analyses of risk factors showed that after adjusting for sex there was strong evidence for a decrease in odds of showing clinical signs per year of age. All samples collected from bears before the outbreak tested negative to NSP and VNT. All cases tested positive to VNT following onset of clinical signs and remained positive during the rest of the follow up period, while only 6 out of 17 cases tested positive to NSP after developing clinical signs. Six animals without clinical signs were tested post outbreaks; five seroconverted using VNT and three animals were seropositive using NSP ELISA. This study provides initial epidemiological parameters of FMD in captive bears, showing that FMDV is easily spread between bears in close proximity and can cause clinical and subclinical disease, both of which appear to induce rapid and long-lasting immunity.

Women's skin care behaviors: How to influence sunscreen use.

BACKGROUND: It is well known that women have been plagued by various skin problems. However, research on the characteristics of women's skin at different ages is still inadequate. In addition, there is a lack of research on the extent of women's skincare habits and skin care awareness. METHODS: A cross-sectional survey on skin was carried out in Shanghai, China, which was conducted by means of a questionnaire. 3678 women, aged 18-59 years, participated in the study. The information collected focused on the importance they place on their skin, the skin problems they have, and their use and perception of skin care products. RESULTS: Before the age of 25, the most common skin problems that women face are dryness and oiliness, while after the age of 30, skin-ageing issues begin to appear and worsen with age. In addition, the higher the level of education, the higher the frequency of and compliance with sunscreen use, and the economy also affects women's use of sunscreen. Importantly, the importance women place on their skin and the level of sunscreen awareness affects women's use of sunscreen. CONCLUSIONS: This study was conducted to understand the skin characteristics of women of different age groups as well as to determine the factors that influence the use of sunscreens, which will not only promote women's skin care practices and product development, but also provide important clues for future activities on sunscreen use and health promotion.

Exploring the mystical relationship between the Moon, Sun, and birth rate.

OBJECTIVE: The Moon has a noticeable influence on the Earth due to its gravity, the most visible manifestation of which are tides. We aimed to see if the Moon's daily cycle, like the Sun's, affects the prevalence and incidence of childbirth. METHODS: In this retrospective cohort study, we examined all deliveries at the Academic Hospital of Udine between 2001 and 2019. All consecutive singleton pregnancies with spontaneous labor and vaginal delivery were included. RESULTS: During the period, 13,349 singleton pregnancies with spontaneous labor and vaginal delivery were delivered in 6939 days. A significantly higher prevalence of deliveries was found with the Moon above the horizon (50.63% vs. 49.37%, p < 0.05). Moreover, during the day, there was a significantly higher prevalence of deliveries than during nighttime (53.74% vs. 45.79%, p < 0.05). Combining the Moon and Sun altitude, the majority of deliveries were registered when both were above the horizon (27.39% vs. 26.13%, 23.25%, or 23.24%, p < 0.05). These findings were confirmed in multivariate analysis after adjusting for parity, gestational age, or season. We found no correlation between birth and the Moon phase. CONCLUSIONS: Our data support the interaction of the Moon and the Sun in determining the time of birth. More research is needed to understand these phenomena and improve our understanding of labor initiation mechanisms.

Understanding the impact of community-based sun safety interventions on a college campus in Texas.

Objective: Examine the impact of a community-based, multi-component sun intervention on the campus of Lee College in Baytown, Texas. Participants: 735 respondents completed the survey as part of a range of campus topics. Methods: Survey data on the program were gathered through an emailed campus-wide survey to better understand the community's perceptions and awareness as well as campaign effectiveness over time. Results: Sun safety self-efficacy and awareness of the importance of sun safety behaviors were high in the community. Students reported a lower level of sun safety self-efficacy than employees. Open-ended responses also offered insight into complex views some community members hold about sun-safety behavior, raising questions about the effectiveness of sunscreen and the need for vitamin D. Conclusions: The paper found high awareness of sun-safe behaviors, high self-efficacy in taking personal action, and appreciation for the institutional effort to care for the community.

Application of Newton's polynomial interpolation scheme for variable order fractional derivative with power-law kernel.

This paper, offers a new method for simulating variable-order fractional differential operators with numerous types of fractional derivatives, such as the Caputo derivative, the Caputo-Fabrizio derivative, the Atangana-Baleanu fractal and fractional derivative, and the Atangana-Baleanu Caputo derivative via power-law kernels. Modeling chaotical systems and nonlinear fractional differential equations can be accomplished with the utilization of variable-order differential operators. The computational structures are based on the fractional calculus and Newton's polynomial interpolation. These methods are applied to different variable-order fractional derivatives for Wang-Sun, Rucklidge, and Rikitake systems. We illustrate this novel approach's significance and effectiveness through numerical examples.
