A cross-sectional analysis of yoga experience on variables associated with psychological well-being

Introduction Previous research has identified numerous physical, psychological, and spiritual benefits associated with the practice of yoga. Indeed, yoga has been linked with improved quality of life, reduced stress, and numerous markers of psychological well-being. In the current research, a cross-sectional design was used to examine whether the psychological benefits associated with yoga only apply to long-term practitioners or whether more “casual,” intermittent yoga experience could produce positive outcomes. Methods An American population of long-term practitioners (n = 129), intermittent practitioners (n = 161), and non-practitioners (n = 164) completed online self-report measures of emotional regulation, trait mindfulness, self-compassion, interoceptive awareness, and spiritual intelligence variables. Results The results indicated that long-term (LT) practitioners scored higher than intermittent experience (IE) practitioners on measures of mindfulness (MLT = 137.3; MIE = 127.6), interoceptive awareness (MLT = 3.4; MIE = 3.1), self-compassion (MLT = 3.4; MIE = 3.1), and spiritual intelligence (MLT = 63.5; MIE = 55.5; all p-value < 0.05). Intermittent practitioners scored higher than no-experience (NE) group on interoceptive awareness (MIE = 3.1; MNE = 2.7) and spiritual intelligence (MIE = 55.5; MNE = 46.6; both p-value < 0.05). Contrary to our hypotheses, yoga experience had no effect on depression, anxiety, or stress levels. Separate mediation analyses demonstrated that interoceptive awareness, spiritual intelligence, mindfulness, and self-compassion each mediated the relationship between yoga experience and emotion dysregulation. Furthermore, emotion dysregulation mediated the relationship between yoga experience and depression, anxiety, and stress. Discussion Taken together, the results of this study suggest that long-term practitioners experience more benefits compared to intermittent and non-practitioners, and that the mechanisms underlying these benefits are multi-faceted.
Limited dorsiflexion predisposes to injuries of the ankle in children

Injuries to the ankle are common in children. We investigated whether decreased dorsiflexion predisposes to such fractures and sprains. Passive dorsiflexion in children with ankle injuries was compared with that in a control group of patients with a normal ankle. The uninjured side was examined to determine flexibility in those patients with ankle injuries. In 82, the mean dorsiflexion was 5.7 degrees with the knee extended and 11.2 degrees with the knee flexed. In 85 controls, the mean dorsiflexion was 12.8 degrees with the knee extended and 21.5 degrees with the knee flexed (p < 0.001, Student's t-test). There was a strong association between decreased ankle dorsiflexion and injury in children. A flexible triceps surae appeared to absorb energy and protect the bone and ligaments, while stiffness predisposed to injury. We suggest that children with tight calf muscles should undergo a regimen of stretching exercises to improve their flexibility.
A weekly spatio‐temporal distribution of drought events over the Po Plain (North Italy) in the last five decades

The aim of this research is to identify and characterize, in terms of length, intensity, and spatial propagation, the main drought events which took place in the Po Valley (Italy) from 1965 to 2017. Two drought indices were applied, the Standardized Precipitation Evapotranspiration Index (SPEI) and Standardized Precipitation Index (SPI). Daily precipitation and temperature series belonging to the National System for the Collection, Processing, and Dissemination of Climatic Data of Environmental Interest (SCIA) database were collected. Subsequent to an accurate quality control, the converted weekly climatic values were spatialized on a 20 × 20 km cell grid, and for each index, weekly severe and extreme drought episodes at a 12‐, 24‐, and 36‐month time scale were calculated. Results showed that the application of two indices is fundamental in the study of drought episodes, and that different triggering factors act over time. Especially, since the 2001 drought, episodes have become stronger in terms of frequency and length, and they seem to be mostly related to changes in the intra‐annual precipitation distribution. An analysis of the spatial propagation also indicates that two spatial gradients follow each other during the analysed period.
Edad relativa, minutos de competición y debut en fútbol profesional

espanolEl objetivo de estudio fue analizar el efecto de la edad relativa (RAE) en todas las categorias formativas de un club de futbol profesional, e identificar si este afecta al tiempo de participacion de los jugadores en competicion y a sus posibilidades de debutar en el futbol profesional. Se analizo la distribucion de las fechas de nacimiento de 334 futbolistas de elite del Real Club Deportivo de la Coruna: 195 jugadores en edades de formacion (GCI) divididos en 11 subgrupos correspondientes a sus categorias de edad (U9-U23), 110 jugadores profesionales (GPE) y 29 jugadores que debutaron en partido oficial con el primer equipo del club desde de las categorias inferiores (GE). Se calculo la suma de todos los minutos disputados por un futbolista en competicion oficial durante una temporada. Los resultados del test ji cuadrado demostraron la existencia de RAE en los 3 grupos de jugadores analizados y en todos los subgrupos de edad de los jugadores del GCI. El RAE fue significativamente menor en el GPE en comparacion con los grupos GCI y GE (Mann–Whitney U-test, p EnglishThe purpose of this study was to analyse the relative age effect (RAE) in all age categories in the development programme of a professional football club and to identify whether playing time and the chances of debut in the first team are influenced by the RAE. We examined the birthdate distributions of 334 elite football players from Real Club Deportivo de la Coruna: 195 young soccer players (DTG) divided into 11 age groups (U-9 to U-23), 110 professional players (FTG), and 29 players who debuted in competitive matches with the club’s first team from the youth development programme (EG). Playing time was calculated by adding up all the minutes played by a player in official competition during a season. The Chi-square test results show that the RAE exists in the 3 groups and in all the 11 age groups of the DTG players. The RAE was significantly lower in the FTG compared to the DTG and EG groups (Mann-Whitney U test, p These findings suggest that the RAE in elite clubs originates fundamentally in the talent selection process in all categories, but mainly in the youngest ones, and is maintained in all the lower categories, influencing the chances of making a first-team debut
Nonlinear Effects on the Precessional Instability in Magnetized Turbulence

By means of direct numerical simulations (DNS), we study the impact of an imposed uniform magnetic field on precessing magnetohydrodynamic homogeneous turbulence with a unit magnetic Prandtl number. The base flow which can trigger the precessional instability consists of the superposition of a solid-body rotation around the vertical ( x 3 ) axis (with rate Ω ) and a plane shear (with rate S = 2 ε Ω ) viewed in a frame rotating (with rate Ω p = ε Ω ) about an axis normal to the plane of shear and to the solid-body rotation axis and under an imposed magnetic field that aligns with the solid-body rotation axis ( B ‖ Ω ) . While rotation rate and Poincaré number are fixed, Ω = 20 and ε = 0.17 , the B intensity was varied, B = 0.1 , 0.5 , and 2.5 , so that the Elsasser number is about Λ = 0.1 , 2.5 and 62.5 , respectively. At the final computational dimensionless time, S t = 2 ε Ω t = 67 , the Rossby number Ro is about 0.1 characterizing rapidly rotating flow. It is shown that the total (kinetic + magnetic) energy ( E ) , production rate ( P ) due the basic flow and dissipation rate ( D ) occur in two main phases associated with different flow topologies: (i) an exponential growth and (ii) nonlinear saturation during which these global quantities remain almost time independent with P ∼ D . The impact of a "strong" imposed magnetic field ( B = 2.5 ) on large scale structures at the saturation stage is reflected by the formation of structures that look like filaments and there is no dominance of horizontal motion over the vertical (along the solid-rotation axis) one. The comparison between the spectra of kinetic energy E ( κ ) ( k ⊥ ) , E ( κ ) ( k ⊥ , k ‖ = 1 , 2 ) and E κ ) ( k ⊥ , k ‖ = 0 ) at the saturation stage reveals that, at large horizontal scales, the major contribution to E ( κ ) ( k ⊥ ) does not come only from the mode k ‖ = 0 but also from the k ‖ = 1 mode which is the most energetic. Only at very large horizontal scales at which E ( κ ) ( k ⊥ ) ∼ E 2 D ( κ ) ( k ⊥ ) , the flow is almost two-dimensional. In the wavenumbers range 10 ≤ k ⊥ ≤ 40 , the spectra E ( κ ) ( k ⊥ ) and E ( κ ) ( k ⊥ , k ‖ = 0 ) respectively follow the scaling k ⊥ − 2 and k ⊥ − 3 . Unlike the velocity field the magnetic field remains strongly three-dimensional for all scales since E 2 D ( m ) ( k ⊥ ) ≪ E ( m ) ( k ⊥ ) . At the saturation stage, the Alfvén ratio between kinetic and magnetic energies behaves like k ‖ − 2 for B k ‖ / ( 2 ε Ω ) < 1 .
Optimization of Reproductive Success in Beef Cattle by Implementation of Estrus Resynchronization, Nutritional Management, and Evaluation of Disease Prevalance

OPTIMIZATION OF REPRODUCTIVE SUCCESS IN BEEF CATTLE BY IMPLEMENTATION OF ESTRUS RESYNCHRONIZATION, NUTRITIONAL MANAGEMENT, AND EVALUATION OF DISEASE PREVALANCE KAITLIN M. EPPERSON 2019 The beef industry is a unique community of operations that employ different management techniques to accomplish a similar goal. Like other facets of animal agriculture, profitability of the beef industry is heavily reliant upon the implemented management practices. Reproductive efficiency is an area of management that has great potential to positively influence the success of beef production. Through the use of reproductive technologies such as estrus synchronization and AI, a greater percentage of females can become bred to superior sires, breeding and calving seasons can be shortened, calf uniformity increased, and economic return maximized (Odde, 1990; Rodgers et al., 2012; Bó et al., 2016). In recognizing the merit of utilization of these reproductive technologies, the possibility of extending these benefits past an initial synchronization and AI can be appreciated. Implementation of estrus resynchronization and additional inseminations has been adopted by the dairy industry, but is slow to be utilized by beef producers. Evaluating the efficacy of estrus resynchronization and a second insemination offers the potential to maximize the previously mentioned benefits in a defined breeding season. Additionally, if reproductive efficiency is to be optimized, disease and nutrition management are also aspects that require consideration. It is understood that appropriate biosecurity practices against reproductive diseases, such as Bovine Viral Diarrhea Virus
Proof of lung muscarinic receptor occupancy by tiotropium: Translational Positron Emission Tomography studies in non-human primates and humans

Introduction Molecular imaging has not been used to support the development of drugs for the treatment of pulmonary disorders. The aim of the present translational study was to advance quantitative pulmonary PET imaging by demonstrating occupancy of the reference asthma drug tiotropium at muscarinic acetylcholine receptors (mAChR). Methods PET imaging was performed using the muscarinic radioligand [11C]VC-002. The key methodological step involved estimating muscarinic receptor binding while disentangling it from the background of non-specific binding. The relationship between tiotropium exposure and receptor occupancy (RO) was assessed in non-human primates (NHPs) after intravenous injection of tiotropium doses at a broad dose interval (0.03–1 µg/kg). The feasibility of measuring RO in the human lung was then confirmed in seven healthy human subjects after inhalation of a single therapeutic dose of tiotropium (18 µg). Results There was an evident effect of tiotropium on [11C]VC-002 binding to mAChRs in lungs in both NHPs and humans. In NHPs, RO was 11 to 78% and increased in a dose dependent manner. Non-displaceable binding in NHPs was about 10% of total binding. In humans, RO was 6%–65%, and non-displaceable binding was about 20% of total binding at baseline. Discussion The results demonstrate that [11C]VC-002 binds specifically to mAChRs in the lungs enabling the assessment of RO following administration of muscarinic antagonist drugs. Furthermore, the methodology has potential not only for dose finding and comparison of drug formulations in future applied studies, but also for evaluating changes in lung receptor distribution during disease or in response to therapy.

DC Arc Flash: Testing and Modeling Incidents in a 125-V Substation Battery Backup System

Station batteries used as a backup source to supply station direct-current (dc) power to relays, etc., present a source of personnel exposure to dc arc flash. However, dc arc flash is less understood compared with the arc-flash phenomena that occur in alternating-current (ac) systems. Some models exist to quantify the potential hazards posed by dc electrical systems; however, there is little empirical data available. Additionally, the lower voltage and/or lower capacity station batteries are even less researched. As a result, a series of arc-flash tests were performed at the Dolan Technology Center of American Electric Power (AEP) utilizing two 125 Vdc batteries with rated capacities of 100 and 150 Ah. For these tests, working distance and gap width were used as independent variables. Upon the conclusion of testing, various relationships were analyzed to generate a predictive model for incident energy. This model serves as a compilation of the empirical data collected during testing and will contribute to future research efforts to better understand dc arc-flash incidents from station batteries.

Objective: The aim of this study was to determine the prevalence of premenstrual syndrome (PMS) among adolescent girls and to associate the PMS with demographic variables.Methods: Quantitative approach and non-experimental descriptive research design was used. The data collection included three parts. Part A: Demographic variables, Part B: Clinical variables, and Part C: A structured questionnaire to assess the prevalence of PMS among adolescent girls. A total of 100 students who fulfilled the inclusion criteria were chosen as samples using non-probability convenient sampling technique. The study was conducted at SRM College of Nursing, SRM University, Kattankulathur.Results: The data were analyzed and interpreted based on the objectives using descriptive and inferential statistics. The study concluded that 26 (26%) of adolescent girls have mild level of PMS; 55 (55%) have moderate level of PMS; and 19 (19%) have severe level of PMS and there is no association between the â€œdemographic variablesâ€ and the â€œlevels of PMS. â€Conclusion: PMS is an issue that every girl and woman has to deal with in her life. There is a lack of information on the process of menstruation and the physical and psychological changes associated with this and proper requirements for managing PMS. The current study proved that most of the adolescent girls were suffering from PMSs. Â
Quantifying and modelling non-local information processing of associative brain regions

Brain world representation emerges not by philosophy but from integrating simple followed by more complex actions (due to drives, instincts) with sensory feedback and inputs such as rewards. Our simulation provides this world representation holistically by identical information encoded as holographic wave patterns for all associative cortex regions. Observed circular activation in cell culture experiments provides building blocks from which such an integrative circuit can evolve just by excitation and inhibition transfer to neighbouring neurons. Large-scale grid-computing of the simulation brought no new emergent phenomena but rather linear gains and losses regarding performance. The circuit integrates perceptions and actions. The resulting simulation compares well with data from electrophysiology, visual perception tasks, and oscillations in cortical areas. Non-local, wave-like information processing in the cortex agrees well with EEG observations such as cortical alpha, beta, and gamma oscillations. Non-local information processing has powerful emergent properties, including key features of conscious information processing.
Estimation of measurement accuracy of the vector information signal parameter under influence multiplicative non-gaussian noise

noise on the useful signal results in a bias of measured parameters estimator. It is easiest to determine a bias of an information parameter when it is not dependent on the estimated parameter. When distribution parameters of multiplicative noise are precisely known it is possible to determine the value of a bias made by this multiplicative noise and go to an unbiased estimate. Estimating the accuracy of measurement of vector information parameter of the processed signal is considered. In this case, as a vector information pa-rameter, the change in the frequency, derivative frequency and phase of the useful signal, which carry information about the parameters of the movement of the object being located, is considered. The estimation of the accuracy of an information parameter of the signal is carried out under the influence of multiplicative noise that has both independent and correlated nature. The calculated ratios are obtained to estimate the frequency, its derivative and the phase of the processed signal under various conditions, for example, when a detected object moves with a constant velocity, when the initial phase of the signal is known, and when an extended object is motionless. It is shown that in the General case the multiplicative noise leads to the displacement of the estimated information parameters of the useful signal; moreover, the greater the value of the displacement, the measurement accuracy is worse. It is proved that the accuracy of measurement of motion parameters increases with the increase in the difference between the PDF of the estimated parameter and the acting multiplicative noise from the Gaussian. It is shown that the measurement error of the information parameters of the useful signal can be significantly reduced by taking into account the Fisher dispersion information (information) about the modulating noise.
Black Feminist Thought and Qualitative Research in Education

Black feminist thought and qualitative research in education is guided by a particular understanding of the learning strategies informed by Black women’s historical experiences with race, gender, and class. Scholars of Black feminist thought remind us of a Black feminist pedagogy that fosters a mindset of intellectual inclusion. Black feminist thought challenges Western intellectual traditions of exclusivity and chauvinism. This article presents a synopsis of the nature and scope of Black feminist thought and qualitative research in education. Further, this article highlights the work of scholars who describe the importance of an Afrocentric methodological approach in the field of education because it offers scholars and practitioners a methodological opportunity to promote equality and multiple perspectives.
Associations of pre-hospital statin treatment with in-hospital outcomes and severity of coronary artery disease in patients with first acute coronary syndrome-findings from the CCC-ACS project

Background The current burden of dyslipidemia, the pre-hospital application of statins and the association of pre-hospital statins with the severity of coronary artery disease (CAD) and in-hospital outcomes in Chinese patients with first acute coronary syndrome (ACS) are very significant and remain unclear. Methods A total of 41,183 patients who underwent coronary angiography and were diagnosed with ACS for the first time from a nationwide registry study (CCC-ACS) were enrolled. The severity of CAD was assessed using the CAD prognostic index (CADPI). The patients were classified into statin and non-statin groups according to their pre-hospital statin treatment status. Clinical characteristics, CADPI and in-hospital outcomes were compared, and a logistic regression analysis was performed to determine whether pre-hospital statin therapy is associated with in-hospital outcomes and CADPI. A sensitivity analysis was used to further explore the issues above. Results The non-statin group had more in-hospital all-cause deaths (1.2 vs. 0.8%, P = 0.010). However, no association exists between statin pretreatment and in-hospital major adverse cardiovascular events (MACEs) or all-cause deaths in the entire population and subgroups (all P > 0.05). Surprisingly, statin pretreatment was associated with an 8.9% higher risk of severely obstructive CAD (CADPI ≥ 37) (OR, 1.089; 95% CI, 1.010–1.175, P = 0.028), and similar results were observed in subgroups of females, those aged 50 to 75 years, and patients with hypertension. Conclusion Statin pretreatment was not related to MACEs or all-cause death during hospital stay, but it was associated with a higher risk of increased angiographic severity in patients with first ACS.
A comparison of cost-effectiveness between doxycycline and azithromycin with topical clindamycin in the treatment of patients with moderate to severe acne vulgaris: Prospective, randomized study

Background: Acne vulgaris is one of the chronic, common dermatological skin diseases with inflammatory lesions, prevalent among adolescents. The management of acne vulgaris is primarily pharmacotherapy comprising both topical and systemic anti-inflammatory and antimicrobials agents. Aims and Objective: Pharmacoeconomic analysis is now an integral part of therapy. There are several studies regarding recommendations, guidelines, efficacy, tolerability, and outcomes of therapies used in acne vulgaris; but hardly any studies comparing the cost-effectiveness of this combination of topical and oral antimicrobials in the treatment of moderate to severe acne vulgaris in our country; hence, this study was taken up to provide useful and valid data. Materials and Methods: This was a randomized, open-label, active-controlled, comparative study of cost-effectiveness analysis of doxycycline and azithromycin in 60 subjects, who gave written informed consent and had moderate to severe acne vulgaris. Azithromycin was given as pulse therapy whereas doxycycline was given once daily with topical clindamycin twice daily for 8 weeks in both groups. Direct and indirect medical costs were considered, average cost-effectiveness ratio (ACER) and cost-effective analysis (CEA) were analyzed. Non-parametric test like MannWhitney test was used to access the efficacy of the drugs and the result was statistically significant. Results were depicted in the form of tables, figures, and graphs. Results: The ACER and CEA showed that azithromycin was better than doxycycline. Conclusion: The study drugs were effective in reducing the lesion count but required long-term treatment; however, azithromycin was more cost-effective than doxycycline.
