The spectroscopic orbits and the geometrical configuration of the symbiotic binary AR Pavonis

We analyze optical and near infrared spectra of intermediate and high resolution of the eclipsing symbiotic system AR Pavonis. We have obtained the radial velocity curves for the red and the hot component from the M-giant absorption lines and from the wings of Halpha, H and He II4686 emission profiles, respectively. From the orbital elements we have derived the masses, Mgiant=2.5 and Mhot =1.0 solar masses, for the red giant and the hot component, respectively. We also present and discuss radial velocity patterns in the blue cF absorption spectrum as well as various emission lines. In particular, we confirm that the blue absorption lines are associated with the hot component. The radial velocity curve of the blue absorption system, however, does not track the hot companion's orbital motion in a straightforward way, and its departures from an expected circular orbit are particularly strong when the hot component is active. We suggest that the cF-type absorption system is formed in material streaming from the giant presumably in a region where the stream encounters an accretion disk or an extended envelope around the hot component. The broad emission wings originate from the inner accretion disk or the envelope around the hot star.We also suggest that the central absorption in H profiles is formed in a neutral portion of the cool giant's wind which is strongly concentrated towards the orbital plane. The nebula in AR Pav seems to be bounded by significant amount of neutral material in the orbital plane. The forbidden emission lines are probably formed in low density ionized regions extended in polar directions and/or the wind-wind interaction zone.Comment: 12 pages, 5 figures, accepted by A&

The Language Gap: Ideologies within Varying Communities of Practice

The “language gap” claim, originally framed by Hart and Risley, has received powerful attention throughout our society regardless of its lack of qualifications. In this paper, I explore language ideologies concerning language development throughout early childhood and its role in future academic achievement. I conducted interviews with university faculty members in Education, preschool and elementary teachers, and parents of young children in order to attain perspectives about their experience within language acquisition and socialization. In short, I found that the participant’s indicative level of expertise affected their ideologies regarding the “language gap” claim as the university faculty in Education aligned their perspectives with unnamed research and few examples of personal experience while teachers and parents more fully relied on their personal experiences. Furthermore, I offer insight on the powerful influence of ideology and the necessary reframing of linguistic differences

Black women burdening: the process of unburdening realism in Dennis McIntyre\u27s split second.

Black women who dramatize reality can experience a transference of burdens if realistic plays reflect their lived experiences. Burdens affect truthful character development and impact the mental, emotional, physical, social and spiritual well-being of Black actresses. This thesis will use the Fall 2021 University of Louisville production of Dennis McIntyre’s Split Second as a case study. Gender and Race studies along with an auto-ethnographic research approach will be used to examine how my portrayal of Alea in Split Second contributed to Black Woman Burdening, a phrase I created to examine how Black fatigue can negatively and specifically affect Black women who perform realistic theatre. This thesis offers a process for the actor to “unburden” by merging realism with the therapeutic benefits of mind, body, emotional, social, and spiritual awarenes

Epidemiological Investigations of Bighorn Sheep Respiratory Disease and Implications for Management

Infectious respiratory disease has long been identified as the cause of bighorn sheep (Ovis canadensis) historical declines and extirpations, and Mycoplasma ovipneumoniae (Movi) is the primary pathogen inducing disease and mortality. Population-level effects of pneumonia events range from mild to extirpation. Variable individual response to pathogen exposure emerges from dynamic interactions between competing evolutionary processes within the host and pathogen. Understanding impacts of this evolutionary warfare is essential to assessing long-term impacts of pathogen invasion and developing appropriate countermeasures to protect population health. Freeranging populations are faced with spillover infections from domestic sheep and goats as well as previously infected conspecifics. The introduction of a novel Movi strain from a spillover event can result in high all-age morbidity and subsequent mortality. We studied the effects of indirect and direct infection of captive bighorn sheep with Movi, a genetically diverse pathogen. We also used known Movi-carriage histories to classify ewes into 1 of 3 Movi carrier classes. We tested the hypothesis that respiratory disease persistence within bighorn sheep populations is driven by chronically Movi infected ewes, and the prediction that lambs born in pens with at least one chronic carrier ewe (treatment) would experience Movi-induced pneumonia mortality whereas lambs born in pens without a chronic carrier ewe (control) would not develop fatal pneumonia. When all mortality causes were pooled across all years of our study, the percentage of lambs that did not survive was more than twice as high when lambs were in born in pens containing at least one Movi chronic shedder ewe (treatment), compared to when only Movi negative and/or intermittent ewes were present in the pen (control; 92% (n = 33 of 36) and 38% (n = 5 of 13). The mean probability of pneumonia-induced mortality for commingled lambs was above 0.75 by 15 days of age and generally remained above that level for the duration of the study. Our model also estimated this probability to be elevated (≥ 0.90) as early as 16 days of age until 45 days of age, and a secondary peak for older, nearly weaned, lambs (105–114 days of age). While conducting a study for Movi detection probability in serial samples, we document unilateral Movi colonization and direct managers on field sampling techniques for reliable disease surveillance of bighorn sheep populations. Our results suggest that active disease control efforts must account for multiple Movi strains to prevent spillover epidemics. Our results also underscore that removal of chronic carriers from a population will aid bighorn sheep recovery efforts

Is The Combined Oral Contraceptive Treatment Of 150 mcg Levonorgestrel And 30 mcg Ethinyl Estradiol Effective In Preventing Bothersome Unscheduled Uterine Bleeding?

Objective: The objective of this selective evidence-based medicine (EBM) review is to determine whether or not the combined oral contraceptive treatment of 150 mcg levonorgestrel and 30 mcg ethinyl estradiol is effective in preventing unscheduled uterine bleeding. Study Design: Review of two randomized controlled trials (RCTs) and one post hoc analysis, published after 2014 all in the English language. Data Sources: Two randomized controlled trials (RCTs) and one post hoc analysis, all of which evaluate the efficacy of the combined oral contraceptive (COC) treatment of 150 mcg levonorgestrel and 30 mcg ethinyl estradiol in preventing bothersome unscheduled uterine bleeding. In both RCTs, an experimental group is compared to a control group receiving an identical appearing placebo. All studies were found using PubMed. Outcomes Measured: Each of the three articles analyzed the effects of the combined oral contraceptive of levonorgestrel and ethinyl estradiol in preventing bothersome unscheduled uterine bleeding. A five-point Likert Scale and bleeding diaries were the methods used to measure bothersome unscheduled uterine bleeding. Results: In the studies by Guiahi et al.2 and Hou et al.6, participants receiving the treatment of combined oral contraceptive showed statistically significant reduction in unscheduled uterine bleeding compared to the control group with p-values of \u3c0.01 (Guiahi) and 0.03 (Hou). The study by Nappi et al.7 compared participants with 0-6 and \u3e6 days of bleeding and showed significant improvement that increased each 91-day cycle of the combined oral contraceptive treatment with a confidence interval of 95% and an odds ratio (OR) of 1.531. Conclusions: Based on the systematic review of the two randomized controlled trials and one post hoc analysis, one can decisively say that 150 mcg levonorgestrel and 30 mcg ethinyl estradiol is effective in treating bothersome unscheduled uterine bleeding. All three studies verified statistically significant reduction in bleeding with use of the therapy

An Analysis of Angelica Kauffman\u27s Cornelia and Penelope Paintings as they Relate to Female Enlightenment Ideals

The neoclassical art movement exemplified the ideals formulated by German scholar and antiquarian Johan Winckelmann by portraying heroes who exhibited self-sacrifice, honor and duty to the state. Almost inevitably both painters and their subjects were male. However, at the same time female artists were depicting classical heroines in a similar fashion. Angelica Kauffman, a Swiss born artist, was able to combine Winckelmann’s thoughts with Enlightenment ideals of the eighteenth century regarding women. When examined in tandem, her numerous canvases which portray Cornelia, Mother of the Gracchi and Penelope, Wife of Odysseus illustrate Enlightenment ideals. The character of Cornelia, exemplifies independence, the importance of education for women, and women’s ever increasing dedication to their children and motherhood. Penelope also shows independence and the necessity of education, but her character focuses more on women as respectful and respected wives within the marital sphere. By creating paintings that exhibited these notions, Kauffman portrayed her own Enlightenment leanings
