Hubble Space Telescope STIS Spectroscopy of VW Hydri during Early Quiescence following a Superoutburst

Hubble Space Telescope Space Telescope Imaging Spectrograph (STIS) observations of VW Hydri 2 and 7 days after the end of a superoutburst reveal a heated white dwarf with deep broad Lyα, narrow metallic absorption features and evidence of a hotter Keplerian-broadened component. We confirm the existence of enhanced abundances of odd-numbered nuclear species P, Mn, and Al as well as an N/C ratio indicative of CNO H-burning thermonuclear processing. Our best single-temperature white dwarf reduced χ2 fit to the first spectrum reveals (1) a DAZQ white dwarf with Teff = 22,500 ± 500 K, log g = 8.0, and photospheric abundances C = 0.3 solar, N = 3.0 solar, O = 3.0 solar, Si = 0.3 solar, Al = 2 solar, Fe = 0.5 solar, Mg = 3.0 solar, Mn = 50 solar, Ni = 0.3 solar, P = 15 solar, and Ti = 0.1 solar. The best-fit white dwarf + accretion belt composite model yields a large improvement in the reduced χ2 value. The accretion belt temperature is 32,000 K and covers a fractional area of 3%, contributing 11% of the flux. The second spectrum 5 days later reveals slightly increased metal abundances except that P is elevated to 20 times solar while Fe has declined to 0.05 times solar. The white dwarf has cooled by ≈1000 K, the belt temperature is 32,000 K, and the fractional area and flux contribution of the belt are 5% and 20%, respectively. These STIS observations confirm that a past (prehistoric? ) thermonuclear runaway has occurred on the white dwarf in VW Hyi. It is expected that the thermonuclear runaway would be strong enough to produce a nova outburst. Therefore, these two classes of close binaries, namely, dwarf novae and classical novae, are linked and can overlap.
Effects of inspiratory muscle training on physical performance during backpack carrying

Purpose: Restricting chest movement when carrying a loaded backpack reduces efficiency and increases the work of the respiratory muscles. The aim of the present study was to investigate the effects of six weeks of inspiratory muscle training (IMT) on respiratory muscle strength and endurance and on physical performance when carrying a load. Methods: Twenty male (age: 32.2 ± 3.4 years) members of the Special Operations Unit of the Slovenian Army volunteered to participate. The experimental group (n=10) trained their respiratory muscles for six weeks against an incremental inspiratory resistance with a breathing apparatus. The placebo group (n=10) performed the same IMT protocol but with a sham inspiratory resistance. Assessment of the subjects before and after IMT included measurements of the maximal inspiratory and expiratory pressures, heart rate measurements, and ratings of perceived physical and respiratory exertion before and after a 60-min walk test with a 25-kg backpack. Results: After six weeks of IMT, the maximum inspiratory pressure measured before and after the 60-minute walk test increased significantly (p < 0.001) in the experimental group by 47 ± 13% and 58 ± 20%, respectively. Inspiratory fatigue was also significantly lower in the experimental group. No changes were observed in the heart rate and the rating of perceived exertion during the walking test. In the placebo group, no significant changes were observed in the measured parameters after IMT.Conclusion: Six weeks of IMT with progressive breathing resistance improves strength and reduces fatigue of the respiratory muscles. Individuals who perform tasks that require them to carry a heavy backpack for extended periods of time may benefit from IMT.
Gingival Pigmentation Pattern in Correlation to Skin Color in a Group of Kurdish People in Sulaimani City

Background: Melanin pigmentation of the gingiva appears in all ethnicities. Excessive pigmentation is an esthetic concern that has increased awareness about depigmentation procedures. This epidemiological study aims to find the correlation between skin color and gingival pigmentation in Sulaimani Governorate, Kurdistan/Iraq. Subjects and Methods: A total of 820 apparently healthy and non-smokers, including 338 males and 482 females with healthy gingiva, aged between (18-40 years old) were enrolled in this study. Clinical examination on the participants’ gingivae was performed to assess color, and the distribution of pigmentations. Afterward the of participants skin color were visually examined and divided into six groups according to the Fitzpatrick scale. Results: Skin color of (53%) of our participants was medium to light brown. Most of the pigmentations were observed in the attached gingiva and interdental papilla (26.83%) and least being in the marginal gingiva and interdental papilla (9.27%). A statistically significant correlation was found between the participants’ skin color, and the intensity of their gingival pigmentations Conclusion: Darker-skinned subjects haveeavieringival pigmentation compared toair-skinned people in Sulaimani Governorate, Kurdistan/ Iraq. The intensity of gingival pigmentation increases with age with the highest rate of gingival pigmentation was in the upper and lower second premolar to premolar area.
PLANT GROWTH REGULATORS, LICORICE EXTRACT, AND SALTS USED IN MEDIA FOR MICROPROPAGATION OF GARDENIA JASMINOIDES

The study for improving the multiplication and rooting systems of Gardenia jasminoides cv. veitchii ensued in 2020–2021 at the Department of Horticulture, College of Agriculture, University of Kerbala, Kerbala, Iraq. The first experiment comprised multiplication, using Benzyl adenine (BA) at the concentrations of 0, 2, 4, and 6 mg L-1 and licorice extract at the concentrations of 0, 1, 2, and 3 g L-1. The second experiment involved the rooting system, including cultivation of gardenia, shoots on MS media with different formulations, i.e., MS media with half strength of basal salts, and a) IBA (0, 0.5, 1, 1.5 mg L-1), b) licorice extract concentrations ( 0, 1, 2, 3 g L-1), MS medium with the full strength of basal salts, c) IBA (0, 0.5, 1, 1.5 mg L-1), and d) licorice extract (0.1, 2, 3 g L-1). The results showed the superiority of benzyl adenine (4 mg L-1) in achieving the highest number of shoots per plant, and the concentration of 2 mg L-1 showed superior in giving the maximum shoot length and the number of leaves per plant. The licorice extract (2 g L-1) achieved the highest number of shoots per plant, while the concentration of 3 gm L-1 proved superior in reaching the maximum shoot length and number of leaves per plant. The Indole 3-butyric acid- IBA (1 mg L-1) revealed the highest rooting percentage, root length, and root dry weight, with IBA (2 mg L-1) being the highest root number. Also, licorice extract (3 g L-1) supplemented to the media with half strength of basal salts displayed superior rooting percentage, root length, and root dry weight.
IL-12, IFN-γ, and T Cell Proliferation to Measles in Immunized Infants

Measles infection in infants is associated with severe complications, and secondary infections are attributed to generalized immunosuppression. Measles binding to its monocyte receptor down-regulates IL-12 which is expected to diminish Th1-like cytokine responses, including IFN-γ. Whether young infants can be immunized effectively against measles is an important public health issue. We evaluated Ag-specific IL-12, IFN-γ, and T cell responses of infants at 6 (n = 60), 9 (n = 46), or 12 mo (n = 56) of age and 29 vaccinated adults. IL-12 and IFN-γ release by PBMC stimulated with measles Ag increased significantly after measles immunization in infants. IL-12 and IFN-γ concentrations were equivalent in younger and older infants, but IL-12 concentrations were significantly lower in infants than in adults (p = 0.04). IL-12 production by monocytes was down-regulated by measles; the addition of recombinant human IL-12 enhanced IFN-γ production by PBMC stimulated with measles Ag, but infant T cells released significantly less IFN-γ than adult T cells under this condition. Of particular interest, the presence of passive Abs to measles had no effect on the specific T cell proliferation or IFN-γ production after measles stimulation. Cellular immunity to measles infection and vaccination may be limited in infants compared with adults as a result of less effective IFN-γ and IL-12 production in response to measles Ags. These effects were not exaggerated in younger infants compared with effects in infants who were immunized at 12 mo. In summary, infant T cells were primed with measles Ag despite the presence of passive Abs, but their adaptive immune responses were limited compared with those of adults.
Associated C IV absorption in radio-loud QSOs - The 3C mini-survey

A spectroscopic survey at 1 A resolution of twelve 3C and 3CR QSOs reveals a very high incidence of C IV absorption complexes within + or - 5000 km/s of the C IV 1548, 1550-A emission-line redshift. Such associated C IV absorption is found to be strong (rest-frame equivalent width equal to or greater than 1.5 A) in six of these powerful, steep-spectrum radio sources, while four others show weaker associated absorption. Such strong associated C IV complexes with z(abs) approximaely equal to z(em) are comparatively rare in a sample of radio-quiet QSOs investigated previously. The evidence for possible correlations with various radio properties is briefly discussed, although no correlations are thus far confirmed to be statistically significant. 29 references.
In situ studies of interfacial contact evolution via a two-axis deflecting cantilever microinstrument

The time-dependent assessment of two contacting polycrystalline silicon surfaces is realized using a microinstrument that allows for in situ surface analysis. The evolution in contact resistance, morphology, and chemistry is probed as a function of contact cycle. Initially, the contact resistance is found to decrease and then increase with impact cycle. Upon prolonged cycling, the fracture of Si grains is observed which grow to form a wear crater. The electrical, morphological, and chemical analyses suggest that the wear of rough polysilicon surfaces due to impact proceeds through three distinct phases, namely plastic deformation of asperities, adhesive wear, and grain fracture.
Spatial Spillover Impact of Sectoral Government Expenditure on Poverty Alleviation in South Kalimantan Province

Poverty is still one of the forefront issues in developing countries. It could hamper the achievement ofsustainable development goals, thereby triggering a recurring call on the government's role in mitigatingpoverty. This paper contributed to the debate on the role of sectoral government spending under thefiscal decentralization policy to combat poverty. Using a case study in South Kalimantan Province, weemployed a spatial panel data analysis covering 13 districts from 2010-2020. This study investigated thepresence of spatial dependency on poverty and the spatial spillover impact of government expenditure—education, health, housing, public facilities, and social protection—on poverty. The research found theexistence of spatial autocorrelation on poverty and the significant high-cluster poverty in the agriculture-based region. The direct estimation from the Spatial Durbin Model uncovered that governmentexpenditure on education, health, and social protection significantly alleviated poverty, while housing andpublic facilities expenditure remained insignificant in reducing the poverty rate. Besides, educationspending also has a significant indirect effect on poverty, indicating the spatial spillover impact ofeducation spending by the neighbors on poverty in a region.
PU.1 interacts with KLF7 to suppress differentiation and promote proliferation in chicken preadipocytes

Krüppel-like factor 7 (KLF7) is a negative regulator of preadipocyte differentiation. Our previous KLF7 ChIP-seq analysis showed that the binding motif of PU.1 was found among the KLF7 binding peaks, indicating that an interaction between KLF7 and PU.1 at preadipocyte gene promoters and other regulatory elements might be common. Here, Co-IP and FRET assays are used to confirm that PU.1 can directly bind to KLF7 and enhance the transcription activity of cyclin-dependent kinase inhibitor 3 ( CDKN3), which is a downstream target gene of KLF7. We show that the PU.1 expression level is decreased during preadipocyte differentiation. Furthermore, PU.1 overexpression and knockdown experiments reveal that PU.1 negatively regulates chicken preadipocyte differentiation, as evidenced by appropriate changes in lipid droplet accumulation and altered expressions of PPARγ, FAS, and PLIN. In addition, PU.1 overexpression promotes preadipocyte proliferation, while knockdown of PU. 1 inhibits preadipocyte proliferation. We further demonstrate that PU.1 inhibits differentiation and promotes proliferation in preadipocytes, in part by directly interacting with KLF7.
The influence of synoptic scale flow on sea breeze induced surface winds and calm zones

Abstract High-latitude sea breezes and the related daytime calm zones were studied through fine-scale two-dimensional idealized simulations by varying the direction and speed of the ambient large-scale geostrophic flow in small steps. Strongest coastal afternoon breezes were obtained for moderate large-scale flows 45◦–90◦ left from the pure offshore direction (as seen from the sea), while calm zones appeared near the coast for weak to moderate large-scale flows about 30◦–90◦ right from offshore, and at the seaward edge of the breeze cell for weak ambient flows 45◦–90◦ right from offshore. The complex daytime evolution of the wind field for ambient winds roughly opposing the sea breeze is illustrated via a few key cases.

The exact location of partition function zeros, a new method for statistical mechanics

A new mathematical mechanism is proposed for locating exactly sections of the locus of the limiting distribution of partition function zeros for model systems in statistical mechanics. Illustrations and applications to the two-dimensional Ising model and the hard square lattice gas are given; the exact location of the branch point singularity for the hard square lattice gas on the negative activity z axis is conjectured to be the negative root of the polynomial (2z6+9z5+42z4+90z3+96z2+27z+2).
Research on Intellectual Dichotomiser 3 Decision Tree Algorithm Model for Financial Analysis of Colleges and Universities

— The rapid development of college information construction has promoted the processing and analysis of a large number of data in the college system. Decision tree algorithm is often used in the field of financial data analysis, but it has a bias in the selection of attributes. Aiming at the defects of the decision tree algorithm in attribute selection, ID3 algorithm in the decision tree algorithm is selected for weighted improvement, and it is optimized based on Synthetic Minority Oversampling Technique (SMOTE) algorithm and Bagging algorithm to balance the positive and negative data of its training samples, thus obtaining the DSB-ID3 financial analysis model. Using this model to analyze the financial data of a university, its G value and F value are both about 0.78, the recognition accuracy rate for normal samples is 0.7345, and the total recognition accuracy rate is 0.7893, which are the highest among the four models. Compared with other models, model designed in this study has significantly improved classification performance, and its distribution is the most centralized, showing superior stability. The experimental results show that the classification effect of model designed in this study is the best, and it shows superior accuracy and stability in the analysis of financial data. Its superior classification performance shows the potential of decision tree algorithm optimization and the feasibility and necessity of improving it. From the experimental data, it can be seen that the service life and parameters of the model designed in this study are obviously better than those commonly used in the financial analysis industry of colleges and universities. It can be seen from the overall analysis that this model provides a practical reference for the application of decision tree optimization in college financial analysis, and greatly improves the accuracy of financial system data analysis.
Insights into the clinical profile and comorbidities of Factitious Disorder in a multispecialty setting in southwest Nigeria: A cases series and review

Background: Factitious disorder (FD) is an under-recognized and under-diagnosed mental condition. Healthcare professionals often have challenges to diagnose and treating the disorder. As a result, needless and endless medical resources are recommended to assess and evaluate those affected. FD may present as a physical condition, a psychological disorder, or maybe both depending on the prominent symptoms. However, there is a strong correlation between having FD and psychiatric symptoms. Main Text: FD occurs in early adulthood, with a mean age of onset of 25 years in both genders, although with differing demographic features. The lifetime prevalence of FD imposed on oneself in clinical settings is 1.0%, 0.1% in the overall population (ranging between 0.007% and 8.0%) and occurs more in female health care professionals. FD may make up 0.6%–3.0% of psychiatric referrals, and it accounts for 3-5% of doctor-patient contacts. In actuality, 1-2% of hospital admissions and an average of 6-8% of all psychiatric admissions have been underreported. The study aimed to highlight the signs and symptoms of FD identified in a psychiatry department of a multispecialty center and to increase the awareness of health practitioners. A critical review of the literature was done with an emphasis on psychological symptoms. PubMed, Mendeley, and Google Scholar were thoroughly searched and full-text publications of journals from 2010-2021 were included. Conclusion: FD is a diagnostic puzzle that necessitates adequate, prompt medical attention as well as social support because of the potentially fatal consequence. A stronger patient-therapist relationship can strengthen the patient's conscious self-control to minimize the symptoms; therefore the healthcare provider has to be open-minded. For the diagnostic enigma to be removed and for ease of treatment, additional research, increasing awareness among medical professionals and the general public, accurate evaluation, diagnosis, and psychotherapy should be encouraged. These case studies will contribute to the knowledge base of FD and improve the quality of care.
Characteristics of precipitation in the Meiyu-Baiu season in the CMIP3 20th century climate simulations.

Characteristics of precipitation in the Meiyu-Baiu season in twenty-two 20th century climate simulations contributed to the World Climate Research Programme’s Coupled Model Intercomparison Project phase 3 (CMIP3) are studied comparing with two observed precipitation data. The distribution of precipitation in the Meiyu-Baiu season is characterized by the narrow Meiyu and Baiu frontal precipitation zone (MFZ and BFZ) extending along the northern rim of the North Pacific subtropical anticyclone (NPSA), the maximum precipitation zone (S. Max zone) along the southern rim of the NPSA, and the minimum precipitation zone (S. Min zone) to the south of MFZ and BFZ. The latitude of these zones and the precipitation within these zones produced by the models are examined, using the 20-year (1980-1999) averaged values for May, June and July.The precipitation in these zones in each month obtained from the respective many-model ensemble average (MEA) coincides approximately with the observation data, except the western “S. Max zone” in May. However, the MEA simulates MFZ, BFZ and “S. Min zone” to the north of their observed latitude in May. MEA reasonably reproduce the latitude of both MFZ and BFZ for June, and the latitude of BFZ and “S. Min zone” for July. The latitude of the “S. Max zone” is approximately reproduced for MJJ.The standard deviation (STD) of the precipitation from the MEA does not change widely from zone to zone and from month to month. However, STD of the latitude of zones varies widely. The STD of the latitude of MFZ and BFZ became larger in June and July. The STD of the latitude of MFZ is larger than that of BFZ. The STD of the latitude for “S. Max zone” is especially large. The models show large deviation from the MEA around the western and southern rim of the NPSA. Low horizontal resolution models tend to yield the larger deviation, in regard to both the latitude and precipitation, as compared with models of medium resolution. However, a few high resolution models still produce large deviation from the MEA. It is hard to state conclusively the influence of the cumulus parameterization scheme on the intense precipitation zones.
Study of Role of Magnetic Resonance Imaging in Evaluation of Non-Traumatic Chronic Shoulder Pain in Adults

Background: A highly helpful diagnostic technique for determining the cause of shoulder pain is magnetic resonance imaging (MRI). Objective: To study the role of MRI in the diagnosis of chronic non-traumatic shoulder pain. Subjects and methods : In this cross-sectional observational research, 60 patients (32 males and 28 females) presented with chronic shoulder pain and limitation of movement. All cases were recruited from the Orthopedic Surgery and Radiodiagnosis Departments at Zagazig University Hospitals. All cases were assessed by Magnetic Resonance Imaging. Results: Fifty-three cases had rotator cuff pathologies, thirty-seven cases had acromioclavicular osteoarthritis, twenty-nine cases had bursitis, fifteen cases had biceps pathologies and nine cases had miscellaneous conditions. A study; 16 (35%) Sub coracoid, 10(16.7%) in Sub-acromial sub deltoid and (5%) Subscapular. Among the current study, 9 (15%) of cases were miscellaneous. Four cases were suffering from interosseous cystic lesions (6.7%) of all cases. Lipoma was seen in 3(5%) of cases. Ganglion cyst was seen in 2(3.3%) of cases. Conclusion: MRI of the shoulders aided in understanding different underlying pathology of chronic shoulder pain and revealed that dependence on only clinical findings and diagnosis could delay their management as well as chronicity development.
Role of Nigella sativa oil and Alpha lipoic acid on Amikacin induced hepatorenal toxicity in rabbits

A mikacin (AK) has long been used as an effective antibiotic to prevent Gram-negative infections. Despite its numerous benefits, Amikacin has considerable hepato-renal toxic adverse effects. The potential preventive benefits of NSO, “Nigella sativa oil” and/or ALA, “Alpha lipoic acid” were investigated in rabbits with Amikacin-induced acute hepa-to- renal injury. Rabbits were treated with AK (100mg/kg BW/day I/M in-jection) alone or with NSO (2ml/kg BW orally) and /or ALA (50 mg/kg BW/day) daily for seven days. Serum biochemical parameters well as tissue oxidative stress indicators were measured to evaluatehepato-renal damage. Rabbits administered AK showed substantial changes in serum biochemical hepato-renal damage indicators with reduction in tissue antioxidant bi-omarkers and rise in hepato-renal oxidant. NSO plus ALA treatment potentially alleviated the AK induced changes in blood and tissue biochemistry. The current study
