Recent publications have described a relationship between fluctuations in environmental physical activity and several aspects of fetal development. This study explored the possible effects of cosmophysical parameters on newborn gender, overall and by maternal age. The gender distribution of 123,368 infants born over a 189-month period (November 1993–July 2009) was analyzed against levels of solar, geomagnetic, and cosmic ray activity at the time of conception. The cohort was then divided into three groups by maternal age ( 35 years) for further analysis. Pearson correlation coefficients and their probabilities were calculated, and chi-square test was applied, as necessary. The physical data were derived from space science centers in the UsA, Russia, and Finland. The results showed that the male/female ratio for the whole cohort over the study period was 1.06. However, on monthly analysis, there was a significant male predominance in most months, with a male/female ratio of up to 4. Younger mothers (s) gave birth to significantly more boys than older mothers. The gender distribution in the three maternal age groups was partially linked to the different physical factors. These findings suggest that environmental physical activity in the month of conception may play a role in newborn gender. Further study is needed to determine the mechanism underlying this effect.

In recent years, many studies were published describing a wide scope of changes related to extreme (stormy) geomagnetic activity. In some countries, prediction of such days is a part of weather prediction information. A number of risk factors like blood coagulation parameters, arterial blood pressure, inflammation markers, and some blood proteins were changing at days of GMA storms. Concomitant studies were published on an inverse phenomenon-increased cardiovascular event at days of Zero GMA, accompanied by high space Neutron activity on the Earth’s surface—a marker of high Cosmic Ray activity. The aim of this study was to compare two groups of Acute Cardiovascular Events (ACE)—Acute Myocardial Infarction (AMI) and deaths from Ischemic Heart Disease (IHD) at days of extreme Cosmic Ray (CRA)-Neutron activity. Patients & methods: 4749 days at years 2000-2012 were studied considering ACE in a 3000 bed hospital in Kaunas, Lithuania. Cosmophysical data of this period was obtained from UsA, Russia, and Finland. ACE was calculated at day of extreme High levels of CRA and following 48 hours. 13629 AMI and 3128 deaths from IHD were included. Results: It was a significant rise in AMI morbidity at day of high CRA (Neutron) activity (≥9300 imp/min). By analysis for each of gender, and patients age groups that were significant difference of AMI for all patients and male >65 y. old at Neutron activity ≥9400 imp/min (p = 0.048;p = 0.03), both gender > 65 y. old at Neutron activity >9500 (p = 0.078) and female >65 y. at Lag 2 (p = 0.07). For deaths from IHD, it was a significant rise at Neutron activity below 9300 imp/min (662 days (13.8%) were above the average of the full observation time-8935 ± 538.083)). Conclusion: At days of high CRA-Neutron activity, it was significantly more AMI. For IHD mortality was higher, but at lower Neutron activity—closer to average Neutron activity and higher GMA.

Honey bees are an established animal model for studying learning and memory related behaviors. In recent years, honey bees have become more common as a model for investigations of molecular biology, including gene expression. Honey bees have been used to extrapolate genetic functions found in other invertebrates, such as Drosophila melanogaster.span> The honey bee model has also provided a means for isolating novel genes, including non-coding microRNA fragments. Integrating the study of learning and memory with molecular genetics, the present work examines the effect of learning acquisition and memory consolidation in free-choice paradigms on the expression of a suite of genes of interest. Results suggest that short-term learning acquisition causes differential expression of microRNA fragments, while memory consolidation differentially affects the expression of the serine/threonine protein kinase gene in honey bees. These results corroborate previous findings suggesting the importance of protein kinases in the formation of long term memory, and suggest that microRNA may play a large role in regulation of cytoskeletal scaffolding proteins.

Background: Daily paediatric asthma readmissions within 28 days are a good example of a low count time series and not easily amenable to common time series methods used in studies of asthma seasonality and time trends. We sought to model and predict daily trends of childhood asthma readmissions over time inVictoria,Australia. Methods: We used a database of 75,000 childhood asthma admissions from the Department ofHealth,Victoria,Australiain 1997-2009. Daily admissions over time were modeled using a semi parametric Generalized Additive Model (GAM) and by sex and age group. Predictions were also estimated by using these models. Results: N = 2401 asthma readmissions within 28 days occurred during study period. Of these, n = 1358 (57%) were boys. Overall, seasonal peaks occurred in winter (30.5%) followed by autumn (28.6%) and then spring (24.6%) (p

Time and environmental physical activity are involved in timing of many medical events. In a recent study published by the National Academy of science, UsA it was shown that month of birth is related to longevity. The aim of this study was to check the month of birth distribution in a great group of AMI patients of both gender, one of the great killers in the developed countries, to check the mentioned paradigm of month of birth and longevity. Methods & Patients: Patients admitted to Cardiology Departments of a tertiary University Hospital in Kaunas, Lithuania with AMI at years 1990-2010 (n-22047) were studied. Month of birth of these patients, total and both gender were checked. Monthly, quarterly and trimester comparison were done. statistical differences established using t-student test and distribution by percents of the yearly months of birth. Results: It was a significant difference in the month of birth of the studied AMI population. January and first quarter and trimester born patients were more often in the studied AMI patients group. The higher morbidity by Cardiovascular diseases can be a significant ingredient in the structure of population longevity. Possible mechanisms explaining our findings are discussed. Conclusion: In the AMI population people born in January, first quarter or trimester of the year are dominating in both gender groups. The results of this study can be an additional confirmation of the paradigm about links between month of birth and longevity.

The interrelationship between human life and death at the end of the XX and beginning of the XXI centuries is the topic of this study. The aim of the study is to study links between time, solar (sA), Geomagnetic (GMA) and Cosmic Ray (CRA) (Neutron) activity and monthly deaths distribution from all and six subgroups of death causes in years 1990-2009 for ad-ditional clarification of the role of exogenic factors in human homeostasis. Methods and patients: 850304 deaths (44657 men, 400647 woman) and 6 subgroups were studied in 240 consecutive months in the Re-public of Lithuania in relation to the months of year (1 - 12), 4 indices of sA (sunspot number and solar Flux), 3 indices of GMA (planetary and regional for the Middle Latitudes), and CRA described by Neutron activity on the Earth's surface-remains of crushed atoms in the high space levels and measured by Imp/min. The cosmophysical data came from space science Institutions in the UsA, Russia and Finland. statistical analysis of the results for monthly comparison are presented. Results: It was a significant and inverse relationship of monthly deaths number for both gender with CRA and sA, less with GMA. It was a significant drop of deaths from IHD and sui-cides. Oncology deaths also show similarity in their timing with other groups. A strong inverse rela-tionship was seen in monthly death number from IHD and stroke. (r = -0.76, p show more seasonality in death's distribution. Most deaths show annual rhythm with acrophase in February. Only suicide pick appears in the summer months. Conclusion: at the beginning of the XXI century, in addition to accepted risk factors, environmental physical activity is linked to timing of death. Cosmic Ray (Neutron) activity is one of the main regulators of this relationship. stroke related deaths are becoming a more prominent cause in the collection of car-diovascular deaths. suicide related deaths show a drop, possibly related to a massive trend for immi-gration i

The present study involves co-precipitation method to grow un-doped and Zr-doped bismuth iron oxide with x_（Zr）=0.10–0.30. The molar solutions of ferric chloride（FeCl_3）, zirconyle chloride（ZrOCl_2）, and bismuth chloride（BiCl_3） are prepared in distilled water, and are allowed to react with sodium hydroxide（Na OH）. The synthesized powders are then converted into pellets, which are sintered at 500℃ for two hours in a muffle furnace. X-ray diffraction（XRD） shows multi-phase formation in un-doped and Zr doped samples. scanning electron microscope（sEM） depicts layered structure at low Zr concentration x_（Zr）= 0.10, while uniform surface with smaller grains and voids is observed at x_（Zr）= 0.20, but at x_（Zr）= 0.30, cracks and voids become prominent. The ferromagnetic nature of the un-doped sample is observed by vibrating sample magnetometer（VsM）, while paramagnetic behavior appears due to Zr doping. The ferromagnetism in un-doped sample is lost by Zr doping, which is due to the formation of additional Fe–O–Zr bonds that induce paramagnetic behavior.

This paper presents a study of hydromagnetic Couette flow of an incompress- ible and electrically conducting fluid between two parallel rotating plates, one of which is oscillating in its own plane. A uniform transverse magnetic field is used, and the induced magnetic field is taken into account. The exact solution to the governing equations is obtained in a closed form. The solution to the problem in the case of vanishing and small finite magnetic Prandtl numbers is also derived from the general solution. The asymp- totic behavior of the solution for large values of the frequency parameter is analyzed to gain some physical insights into the flow pattern. Expressions for the shear stress at both the oscillatory and stationary plates due to primary and secondary flows and mass flow rate in the primary and secondary flow directions are also obtained. The results of the fluid velocity and the induced magnetic field are presented. The shear stresses on the plates due to the primary and secondary flows and the corresponding mass flow rates are presented in a tabular form.

Dune barrier systems represent highly sought-after coastal landscapes for tourism and urban development around the world. However, a century ago, they were considered hazardous environments due to their great dynamic nature. As a result, stabilization practices were considered necessary. The systematic introduction of fast-growing exotic trees helped stabilize the sand, making it easier for tourism urbanization to take place, but also leading to erosion processes. This paper aims to assess long-term changes in vegetation cover over a large temperate barrier in Argentina. This complex region includes urban resorts, afforestation zones, and protected areas. A GIs-based geospatial analysis was conducted using a large satellite database(> 350 images), and the future evolution of the vegetation was modeled. The results revealed two primary spatiotemporal patterns associated with a gradual expansion of vegetation cover, accompanied by a concurrent reduction in sandy areas. In 1986, the dune area comprised 75% more surface than vegetation, whereas in 2021, it represented 60% less than vegetation. Furthermore, the 2050 scenario suggests a potential 40% reduction of dunes in certain areas. It is necessary to enhance management actions aimed at maintaining dune mobility and ensuring local and regional sediment balance. Long-term management strategies must focus on restoring native plant communities and controlling invasive species, and avoiding new dune fixation initiatives based on the introduction of exotic species.
