Varied spawning patterns of reef corals in Nha Trang Bay, Vietnam, western South China Sea

Nha Trang Bay is located in the south-central waters of Vietnam and forms part of the most diverse region within the western South China Sea. Oceanographic studies indicate that this coastal area is not influenced by cold water masses from the north in winter but is subjected to summer upwelling. Coral spawning patterns of four species were monitored by collecting samples of colonies at Hon Mieu Island (12°11’37.31”N and 109°14’1.82”E) and two nearby sites during 2016–2019. Mature eggs were recorded inside polyps Acropora florida and A. robusta branches sampled prior to and after the full moon of late March to early April in 2018, and March in 2019. Spawning for both species was inferred to have occurred 6–8 nights after full moon in early April 2018, and 2–3 nights after full moon for A. robusta in March 2019. Colonies of the tabulate coral A. hyacinthus were inferred to have spawned between 6–11 nights after the full moon of March 2019, up to six nights after the spawning of A. robusta. In contrast, the spawning time of the massive coral of Dipsastraea pallida occurred one month later than that of branching Acropora corals, during the period before and after the full moon of late April to early May in 2018, and 4–5 nights after the full moon in April 2019. Monitoring of the ratio of pigmented mature eggs over time and inferred spawning periods of the three Acropora species and D. pallida indicated that spawning of corals in Nha Trang Bay occurs over an extended spawning period from March to May. Therefore, spawning in these species does not appear to be concentrated during a short mass spawning period over a few nights.

Blessing of the moon: cultural beliefs, birth timing and child health in Nepal

In many South Asian contexts, specific dates are auspicious and inauspicious for health-related behaviours and outcomes. This study analysed the effect of lunar date-related auspicious beliefs in Nepal on childbirths and neonatal health outcomes. Using the daily birth records from a tertiary maternity hospital, we empirically examined whether births occurred disproportionally around full moon days. We found an average of 10.7 extra births on and before full moon days, with an average of 7.5 extra Caesarean deliveries on full moon days. We demonstrated that births occurring on or before the full moon day have poor neonatal health outcomes. However, a subsample analysis suggested better health outcomes for low-risk mothers and worse health outcomes for high-risk mothers. These findings suggest that low-risk mothers may move their deliveries to auspicious dates with fewer complications than high-risk mothers. The results emphasise the need for additional research to distinguish health service demand from supply influences on birth timing in Nepal.

Effect of Varied Phases of Lunar on the Growth and Yield Parameters of Rice Varieties

Aim: To understand and reason out the effect of lunar phases on the rice crop growth and development.
 Study Design: Experiment was laid out in Factorial Randomized Block Design.
 Place and Duration of Study: Field trial was conducted in the wetland farm of Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu during the Navarai season (Dec. 2021 – Apr. 2022).
 Methodology: Treatment consists of two factors viz., Sowing date (4 Nos.) weekly sowing with respect to lunar phases – New moon, first quarter, full moon and third quarter) and Varieties (4 Nos.) in which two organic (i.e. Kullakar, Karunkuruvai) and two conventional varieties (ADT 43, ASD 16). Normal cultivation practices were followed as per the Tamil Nadu Crop Production Guide 2021.
 Results: The pooled mean value revealed that the seeds sown at full moon gave significant positive influence on the growth parameters such as plant height, number of tillers, leaf area index and dry matter production compared to other sown dates. Whereas the treatments that had flowering stage synchronized with full moon phase were produced more yield and dry matter content.
 Conclusion: The rice varieties sown in full moon phase exhibited superior growth on compared to other lunar phases and the treatments had flowering synced with full moon phase resulted with more yield and dry matter production.

Full Moons and Forking Paths

Abstract The claim that fatal motorcycle accidents are more likely when there is a full moon is a compelling example of what Gelman and Loken call a “garden of forking paths”. Gary Smith finds that, under a variety of assumptions, the number of accidents and fatalities on full-moon nights is not unusually large at all

“I'll struggle, and I'll fall…I'll have my days, but it's okay”

Sixties scoop survivors possess different levels of cultural knowledge. Our objectives were for Indigenous women 1) to increase their cultural knowledge through teachings and engagement with Knowledge Carriers, 2) to have other supports and resources they require identified, and 3) to participate in a Full Moon Ceremony. Community-based research principles were used to establish the study design and research process. Teaching circles and Full Moon Ceremonies were held and experiences in the study collected through focus group discussions. Five themes were identified which included the manifestations of the sixties scoop, longing for culture, (re)connecting to culture, the impacts of culture, and barriers to practicing culture. Important recommendations emerged regarding the practice of culture in ceremony and in programs.

A Case Study of Tidal Analysis Using Theory-Based Artificial Intelligence Techniques for Disaster Management in Taehwa River, South Korea

Monitoring tidal dynamics is imperative to disaster management because it requires a high level of precision to avert possible dangers. Good knowledge of the physical drivers of tides is vital to achieving such a precision. The Taehwa River in Ulsan City, Korea experiences tidal currents in the estuary that drains into the East Sea. The contribution of wind to tide prediction is evaluated by comparing tidal predictions using harmonic analysis and three deep learning models. Harmonic analysis is conducted on hourly water level data from 2010–2021 using the commercial pytides toolbox to generate constituents and predict tidal elevations. Three deep learning models of long short-term memory (LSTM), gated recurrent unit (GRU), and bi-directional lstm (BiLSTM) are fitted to the water level and wind speed to evaluate wind and no-wind scenarios. Results show that Taehwa tides are categorized as semidiurnal tides based on a computed form ratio of 0.2714 in a 24-h tidal cycle. The highest tidal range of 0.60 m is recorded on full moon spring tide indicating the significant lunar pull. Wind effect improved tidal prediction NSE of optimal LSTM model from 0.67 to 0.90. Knowledge of contributing effect of wind will inform flood protection measures to enhance disaster preparedness.

Effect of seasonal and lunar cycle variability on phytoconstituents of <em>Calotropis Procera</em> (Ait.) R. Br. Aerial parts

Calotropis procera is wild, evergreen plant belongs to Asclepiadaceae family and used in an Indian traditional system of medicine since ancient times. C. procera employed the drug bestowed with R. asaviryadi (Therapeutic principle and potency) quality must be collected to achieve good therapeutic results. Therefore, advocate the collection practice and seasonality that may affect qualitatively and quantitatively to the drug. This is because moonlight is stronger than sunlight. The study aims at seasonal and lunar based aerial parts collection, extraction and quantitative phytochemical analysis. This study found a significant shift in the production of bioactive metabolites during the lunar cycle (full moon and new moon). Results revealed maximum carbohydrate and protein content were found in leaves and floral at PSFM respectively. Flavanoid (76.89±1.02 mg g-1) and phenolics (84.41±1.09 mg g-1) values were higher in leaves at PWFM and PWNM while tannin and cardiac glycoside (80.67±1.44 mg g-1) attained maximum content at PRFM and PSFM in buds respectively. The study of lunar and seasonal based variations of C. procera phytoconstituents emphasize that effective and concentrated drugs can be extracted during the full moon to treat various diseases globally including local people with a minimum exploitation rate.

Uji Akurasi Arah Kiblat Menggunakan Azimut Bulan Purnama

The community often faces problems and problems related to the worship of Muslims, Muslims are also required to carry out obligations that are important factors in the Islamic religion, especially the obligation of prayer that leads to the Kakbah. So far, the measurement of the direction of the Qibla in most methods always uses the Sun, the Sun is one of the celestial bodies that can be used as a reference to measure the direction of the Qibla either in the shadow of the Sun or the azimuth of the Sun. In this case, the author wants to test using the azimuth of the full moon, because there are still many who do not know that the measurement of the direction of the Qibla can not only be with the Sun but can also use the Moon. To find out the extent of the accuracy of the results of measuring the direction of the Qibla with the azimuth of the Moon, the authors formulated several research questions. 1 what is the technique of measuring the direction of the qibla using the azimuth of the full moon? 2 what is the accuracy of qibla direction using the azimuth of the full moon? To answer the research question, the author uses a qualitative research method with an astronomical approach, the primary data used are in the form of trial results of measuring the direction of the Qibla during the full Moon, namely the night of the 14th, and 16th which is marked with a lunar illumination value above 95 percent, and night 15 which is marked with a Lunar illumination value of 100 percent. on the first day obtained a value difference of 00° 03' 50", on the second day obtained a difference in value of 0° 02' 20 and on the third day obtained a difference in value of 0° 02' 12 The collected data were analyzed by descriptive analysis method. The results of the study can be concluded that the technique of measuring the direction of the Qibla using the azimuth of the full Moon is the same as the technique of measuring the direction of the Qibla by using the azimuth of the Sun. Meanwhile, the accuracy is still very accurate, where the results of the trial measurement of the direction of the Qibla by using the azimuth of the full Moon only have an average difference of 00 ° 02ʼ 12 " arc from the results of measuring the direction of the Qibla using the Azimuth of the Sun.

Lunar cycles of geomagnetic activity and emergency ambulance calls

The distributions of geomagnetic activity levels and the number of emergency ambulance calls by days of the lunar (synodic) month were mapped. The input for the study was Kp index data and the anonymized catalog of ambulance calls to the Petrozavodsk Emergency Care Hospital in 2015–2017. The data were processed using the superposed epochs method and the clustering and trend isolation algorithms. High daily Kp indexes are mainly grouped around new moon while low Kp indexes – near full moon. The distributions of the number of emergency calls for cardiovascular diseases, mental disorders, and neuropathies have their specific features. Possible causes of lunar cycle-related effects of geomagnetic activity and the peculiarities of emergency ambulance calls distributions are discussed

Abstract 2501: Identification and characterization of key players in the Ewing Sarcoma metastatic process

Abstract Metastasis at diagnosis is the most adverse prognostic factor in Ewing Sarcoma (ES), drastically decreasing patients’ overall survival down to <30%1. However, mechanisms leading to metastasis in this disease remain poorly understood. To deepen our knowledge on the main players in ES metastasis, Microarray (Clariom™ D Array, Affymetrix) and phosphoarray (Phospho Explorer Antibody Arrays, Full Moon Biosystems) analyses were performed on primary tumours (n=5) and metastases (n=12) samples from an spontaneous metastatic ES mouse model2. After normalisation and bioinformatics analysis, a list of differentially expressed genes/proteins between the 2 sample groups was obtained. Candidates were validated by qPCR (TaqMan™ probes) and Western Blot, and further characterised in vitro through loss-of-function phenotypic assays (proliferation, clonogenic and migration) using siRNAs and/or inhibitors. Several genes and proteins of interest, including LOXHD1, confirmed to be overexpressed in metastases samples compared to primary tumours as identified by microarray/phosphoarray analyses and qPCR/Western Blot validation. Also, candidates subjected to transient loss-of-function phenotypic assays significantly decreased in all cases tumorigenic and/or metastatic capabilities of ES cells when suppressed. Additionally, LOXHD1 showed upregulation in sphere-growing ES cells, validating its role in ES hypoxia and metastasis as demonstrated previously3. Using stable knock-out models of the genes of interest, the exact mechanism and pathways in which these candidates play a role in ES metastasis will be further studied in vitro and in vivo. Also, their clinical relevance will be explored in several cohorts of patients by immunohistochemistry on Tissue Microarrays. [1] Grünewald, TGP et al. 2018, Nat Rev Dis Prim, 4(1), pp.1-22.

Speckle Interferometric Observations With the Gemini 8-m Telescopes: Signal-to-Noise Calculations and Observational Results

Using 3 years of observations with the Zorro and ’Alopeke speckle interferometric instruments at Gemini South and North, respectively, we present an analysis of the sensitivity of the data taken in two narrow-band optical filters centered at 562 and 832 nm (widths of 54 and 40 nm, respectively). In this paper we focus on model calculations of the predicted signal-to-noise values achievable and the results of over 2500 actual observations. We find that S/N values of several 100 are easily achieved, but that the sky background during full moon is a very limiting factor in the observations, especially those performed in the short-wavelength (blue) optical spectral range and for targets fainter than R ∼14. A comparison of our Gemini speckle observations over six observing semesters reveals that red band-pass observations provide more robust results in general, likely due to better atmospheric performance at these wavelengths. Using the identical instruments on Gemini North and South, we find that similar results are obtained, yielding typical contrast limits of 5-9 magnitudes from the diffraction limit out to 1.2″ for a range of target brightness (optical magnitudes from ∼ 3 to >16). Using our S/N model along with the observational results, an estimation of the contrast limits achievable for a given observation can be predicted based on the target brightness, sky illumination and seeing conditions, and the total integration time.

Temporal activity patterns of North China leopards and their prey in response to moonlight and habitat factors.

The nocturnal activities of predators and prey are influenced by several factors, including physiological adaptations, habitat quality and, we suspect, corresponds to changes in brightness of moonlight according to moon phase. In this study, we used a dataset from 102 camera traps to explore which factors are related to the activity pattern of North China leopards (Panthera pardus japonensis) in Shanxi Tieqiaoshan Provincial Nature Reserve (TPNR), China. We found that nocturnal activities of leopards were irregular during four different lunar phases, and while not strictly lunar philic or lunar phobic, their temporal activity was highest during the brighter moon phases (especially the last quarter) and lower during the new moon phase. On the contrary, roe deer (Capreolus pygargus) exhibited lunar philic activity, while wild boar (Sus scrofa) and tolai hare (Lepus tolai) were evidently lunar phobic, with high and low temporal activity during the full moon, respectively. In terms of temporal overlap, there was positive overlap between leopards and their prey species, including roe deer and tolai hare, while leopard activity did not dip to the same low level of wild boar during the full moon phase. Human activities also more influenced the temporal activity of leopards and wild boar than other species investigated. Generally, our results suggested that besides moonlight risk index (MRI), cloud cover and season have diverse effects on leopard and prey nocturnal activity. Finally, distinct daytime and nighttime habitats were identified, with leopards, wild boar, and tolai hare all using lower elevations at night and higher elevations during the day, while leopards and roe deer were closer to secondary roads during the day than at night.

Revisiting an ancient legend: influence of the lunar cycle on occurrence of first-ever unprovoked seizures.

The mythical effect of the lunar cycle on seizures has been debated over time. Previously healthy individuals presenting with first-ever seizures in whom investigations are negative often invoke questions about potential reasons including a full moon. To determine whether there is a temporal relationship between the occurrence of the first-ever unprovoked seizure and the lunar cycle. We studied adults who presented with a first-ever unprovoked seizure to two tertiary centres in Australia. Seizure onset time was obtained from the emergency department and ambulance documentations. We used Poisson regression modelling and incidence rate ratios (IRR) to determine whether seizures have a preponderance for a particular lunar phase. We performed further analysis on 'first seizure epilepsy' and 'first seizure not epilepsy' subgroups based on the International League Against Epilepsy criteria for a diagnosis of epilepsy after a single unprovoked seizure. We analysed 1710 patients (38% females; median age 39 years), of whom 18% had epileptiform abnormalities on electroencephalogram (EEG) and potentially epileptogenic lesions were detected on neuroimaging in 28%. Based on the EEG and imaging findings, 684 (40%) patients were categorised as 'first seizure epilepsy' and 1026 (60%) 'first seizure not epilepsy'. The whole cohort and subgroup analysis demonstrated no significant difference in the seizure occurrence among the four lunar quarters. First unprovoked seizures are not influenced by the lunar cycle. Patients pondering the cause of their first-ever unprovoked seizure can be reassured that the full moon was not responsible.

Temporal patterns of weekly births and conceptions predicted by meteorology, seasonal variation, and lunar phases.

BackgroundData reporting the number of births given by women resident in Vienna for each week between 1999 and 2019, and the duration (in weeks) of their pregnancies, were used to estimate the week of conception. When preliminary examinations detected cyclical patterns for births and conceptions, a series of Poisson regressions for births and conceptions were performed to assess whether these cycles could be associated with lunar or solar phases.MethodsTo that end 2 sine-cosine functions, 1 with a wavelength of 1 year (365.25 days) and 1 with a wavelength of 29.529 days, the latter resembling the average length of a lunar cycle, were constructed. In addition, also average weekly temperatures were included in the models.ResultsSame week temperature was a strong non-linear predictor for both births and conceptions. Extreme temperatures, especially hot temperatures, increased the number of births while the numbers of successful conceptions were decreased by extreme temperatures. Regarding annual variation in conceptions, the lowest values were found in May and the highest in late autumn and early winter. Therefore, the highest numbers of births are observed in the summer. As per lunar variations, the highest numbers of conceptions occurred at the full moon and the highest numbers of births at the waxing crescent to first quarter moon.DiscussionThe latter results should be treated with caution, as they are not hypothesis driven. Furthermore, literature reports on this topic are conflicting. Nevertheless, these findings will be useful in further analyses examining air pollution effects.

Evidence of circalunar rhythmicity in young children's evening melatonin levels.

In adults, recent evidence demonstrates that sleep and circadian physiology change across lunar phases, including findings that endogenous melatonin levels are lower near the full moon compared to the new moon. Here, we extend these results to early childhood by examining circalunar fluctuations in children's evening melatonin levels. We analysed extant data on young children's circadian rhythms (n=46, aged 3.0-5.9 years, 59% female). After following a strict sleep schedule for 5-7 days, children completed an in-home, dim-light circadian assessment (<10 lux). Salivary melatonin was assessed at regular 20- to 30-min intervals until 1 h past each child's scheduled bedtime. Melatonin levels varied significantly across lunar phases, such that melatonin was lower in participants assessed near the full moon as compared to near the new moon. Significant differences were observed at 50 min (meanfull =2.5 pg/ml; meannew =5.4 pg/ml) and 10 min (meanfull =7.3 pg/ml; meannew =15.8 pg/ml) before children's scheduled bedtime, as well as at 20 min (meanfull =15.5 pg/ml; meannew =26.1 pg/ml) and 50 min (meanfull =19.9 pg/ml; meannew =34.3 pg/ml) after bedtime. To our knowledge, these are the first data demonstrating that melatonin secretion, a process regulated by the human circadian system, is sensitive to changes in lunar phase at an early age. Future research is needed to understand the mechanisms underlying this association (e.g., an endogenous circalunar rhythm) and its potential influence on children's sleep and circadian health.

Environmental parameters modulate lead chloride toxicity on Artemia salina

Introduction: Different environmental conditions can influence the effects of toxic agents on living beings. Recently, a series of experiments performed in Artemia salina submitted to different kinds of intoxication have shown that both, isotherapic and succussed water can change Artemia salina´s bio resilience at different levels. Moreover, it seems to vary according to the circalunar cycle. Objective: To verify if circalunar phases and water agitation can modify the toxicity of lead chloride on Artemia salina in vitro. Methodology: Artemia salina cysts were exposed to seawater containing 0.04% of lead chloride (equal to EC10 or 10% effective concentration, previously determined in a pilot study) in 96-well culture plates. Thirty-six experimental repetitions were performed in four series to observe the possible effects of adding stirred water, the so-called succussed water, and the moon phases. The hatched cysts were recorded after 48 hours using a digital microscope (1000x magnification) to identify the hatching percentage and the viability and mobility of the born nauplii. Results: The exposition of cysts to PbCl2 led to an increase in the hatching rate, and it was more evident during the full moon (p = 0.00014) The addition of succussed water into the seawater medium reduced this effect to the baseline levels. An increase in mobility was seen in nauplii born from exposed cysts during the full moon (p = 0.00077), but this effect was not affected by the treatment with succussed water. Discussion: Although the effects of lead chloride EC10 on the increase of nauplii hatching were expected, two environmental variables changed the sensitivity of cysts to this harmful stimulus. The circalunar cycle varied the hatching rate according to the moon phase, even in laboratory conditions, and the addition of succussed water into the medium reduced the hatching rate, even with different intensities according to the moon phase. The organization of nano and microbubbles generated after the succussion of water could be related to this protective effect and can explain, at least partially the effects of high diluted preparations on this biological context. Conclusion: Environmental factors, such as the circalunar cycle and products of water agitation, can modulate the adaptative control of hatching in Artemia salina exposed to lead chloride at EC10.

Penelope Umbrico and Flickr: from Niépce to the moon and back

Penelope Umbrico’s series entitled Everyone’s Photos Any License (2015-) gathers photographs of the full moon that she selected from among the millions of similar images of the theme on the image-sharing website Flickr. In this paper, I study Umbrico’s gesture, drawing from the flow of online digital images to give shape to often monumental photographic installations, using photographs of the moon taken by others. Her project is inscribed in an image ecology that defends a recycling approach in the context of the overwhelming available images online. I argue that if Umbrico’s series takes part in contemporary practices, it also refers to the history of photography and its tight links with astronomy. Drawing on the history of the photographs of the moon in the nineteenth century to the abundance of digital photographs today, I attempt to show that Umbrico’s series both thematizes the technical challenges of photographing the moon and the ongoing fascination it evokes, in a time of space tourism projects. I argue that the artist’s act of borrowing people’s images of the moon mirrors our possessive relationship with images in the digital age and thus questions the notions of authorship and of uniqueness in today’s flow of images.

Analysis of bioactive compounds from Gracilaria foliifera based on lunar phases

Gracilaria foliifera, sustainable renewable resources in the marine environment. Gracilaria, a genus of red algae, notable for its economic importance as an agarophyte. In the present study, experiments were performed to investigate the phytochemical constituents of Gracilaria foliifera. Samples were collected during three different lunar phases namely new moon, full moon and between days. The collected seaweeds were shade dried and extracted by ethyl acetate. The crude metabolites are subjected to phytochemical analysis, antioxidant activity, and qualitative analysis of the compounds by TLC. Further the crude extract was evaluated by GCMS. Among the different lunar phases, the presence of phytochemical compounds, antioxidants activity, is maximum during the full moon days which also showed appreciable amount than the samples collected during new moon phase and transition phase.

Home sweet home: spatiotemporal distribution and site fidelity of the reef manta ray (Mobula alfredi) in Dungonab Bay, Sudan

BackgroundReef manta ray (Mobula alfredi) populations along the Northeastern African coastline are poorly studied. Identifying critical habitats for this species is essential for future research and conservation efforts. Dungonab Bay and Mukkawar Island National Park (DMNP), a component of a UNESCO World Heritage Site in Sudan, hosts the largest known M. alfredi aggregation in the Red Sea.MethodsA total of 19 individuals were tagged using surgically implanted acoustic tags and tracked within DMNP on an array of 15 strategically placed acoustic receivers in addition to two offshore receivers. Two of these acoustically monitored M. alfredi were also equipped with satellite linked archival tags and one individual was fitted with a satellite transmitting tag. Together, these data are used to describe approximately two years of residency and seasonal shifts in habitat use.ResultsTagged individuals were detected within the array on 96% of monitored days and recorded an average residence index of 0.39 across all receivers. Detections were recorded throughout the year, though some individuals were absent from the receiver array for weeks or months at a time, and generalized additive mixed models showed a clear seasonal pattern in presence with the highest probabilities of detection occurring in boreal fall. The models indicated that M. alfredi presence was highly correlated with increasing chlorophyll-a levels and weakly correlated with the full moon. Modeled biological factors, including sex and wingspan, had no influence on animal presence. Despite the high residency suggested by acoustic telemetry, satellite tag data and offshore acoustic detections in Sanganeb Atoll and Suedi Pass recorded individuals moving up to 125 km from the Bay. However, all these individuals were subsequently detected in the Bay, suggesting a strong degree of site fidelity at this location.ConclusionsThe current study adds to growing evidence that M. alfredi are highly resident and site-attached to coastal bays and lagoons but display seasonal shifts in habitat use that are likely driven by resource availability. This information can be used to assist in managing and supporting sustainable ecotourism within the DMNP, part of a recently designated UNESCO World Heritage Site.
