Interaction of metsulfuron and nitrogen fertilizer in Tall Fescue forage systems

Tall Fescue (Schedonorus arundinaceus) is an introduced cool-season bunch grass that is a vital component of forage systems that support beef cattle production in Missouri and much of the eastern United States. This cool-season grass is known for its high forage yield and resistance to environmental stressors such as drought, pest, and grazing. The resilience of tall fescue to stress is attributed to a symbiotic relationship with the fungal endophyte Epichloe coenophiala, which produces ergot-like alkaloids that can negatively impact livestock performance. Replacement of alkaloid producing tall fescue cultivars, such as K31, has been suggested as a strategy to reduce ergot-like alkaloid consumption by livestock; however, this requires extensive resources and time. It has been reported to cost $250 to $400 per acre to replace tall fescue, with an additional 18 months of no grazing while new species emerge. Most current research efforts have focused on managing tall fescue to reduce toxicity risk by decreasing amounts of alkaloids consumed by livestock. Removing parts of the plant, such as the stems and seedheads, that contain greater concentrations of alkaloids by physical or chemical seedhead suppression has proven to be a successful strategy. A metsulfuron herbicide and nitrogen fertilizer were applied on pastures grazed by stocker cattle for three years to evaluate impacts on toxicity and productivity of the forage system. Metsulfuron herbicide reduced seedhead density by 80 percent and decreased ergovaline production; however, this management strategy also caused a decrease in forage yield. Nitrogen fertilizer recovered forage yield losses due to metsulfuron herbicide. Seedhead reduction in response to metsulfuron has potential for reducing alkaloid exposure when grazing endophyte-infected tall fescue.
Quantum interference in spontaneous emission from a V-type three-level atom in photonic crystals

Studying the spontaneous emission of a V-type three-level atom embedded in a photonic crystal (PC) by fractional calculus, we found that the atomic excited states in the anisotropic PC can be expressed as a superposition of four dressed states analytically. Through detuning two allowed atomic transition energies with respect to the photonic band edge, the coupling between these two transitions leads to three dynamic regimes, namely non-Markovian decay, damped quantum interference and quantum interference, classified by the numbers of contributed bounded dressed states. From the degree of quantum interference of two atomic transitions, we found the energy exchange between the atom and PC reservoir is the lowest as the excited states become degenerate but with maximum quantum interference when the atom is prepared at one of the excited states. The results also show that excited states prefer to stay out of phase at all detuning energy except for near degenerate. Therefore, we can control the spontaneous emission rate not only by the amount of detuning frequencies but also the relative phase of initial states.
Green Synthesis of Endolichenic Fungi Functionalized Silver Nanoparticles: The Role in Antimicrobial, Anti-Cancer, and Mosquitocidal Activities

Green nanotechnology is currently a very crucial and indispensable technology for handling diverse problems regarding the living planet. The concoction of reactive oxygen species (ROS) and biologically synthesized silver nanoparticles (AgNPs) has opened new insights in cancer therapy. The current investigation caters to the concept of the involvement of a novel eco-friendly avenue to produce AgNPs employing the wild endolichenic fungus Talaromyces funiculosus. The synthesized Talaromyces funiculosus–AgNPs were evaluated with the aid of UV visible spectroscopy, dynamic light scattering (DLS), Fourier infrared spectroscopy (ATR-FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The synthesized Talaromyces funiculosus–AgNPs (TF-AgNPs) exhibited hemo-compatibility as evidenced by a hemolytic assay. Further, they were evaluated for their efficacy against foodborne pathogens Staphylococcus aureus, Streptococcus faecalis, Listeria innocua, and Micrococcus luteus and nosocomial Pseudomonas aeruginosa, Escherichia coli, Vibrio cholerae, and Bacillus subtilis bacterial strains. The synthesized TF-AgNPs displayed cytotoxicity in a dose-dependent manner against MDA-MB-231 breast carcinoma cells and eventually condensed the chromatin material observed through the Hoechst 33342 stain. Subsequent analysis using flow cytometry and fluorescence microscopy provided the inference of a possible role of intracellular ROS (OH−, O−, H2O2, and O2−) radicals in the destruction of mitochondria, DNA machinery, the nucleus, and overall damage of the cellular machinery of breast cancerous cells. The combined effect of predation by the cyclopoid copepod Mesocyclops aspericornis and TF-AgNPS for the larval management of dengue vectors were provided. A promising larval control was evident after the conjunction of both predatory organisms and bio-fabricated nanoparticles. Thus, this study provides a novel, cost-effective, extracellular approach of TF-AgNPs production with hemo-compatible, antioxidant, and antimicrobial efficacy against both human and foodborne pathogens with cytotoxicity (dose dependent) towards MDA-MB-231 breast carcinoma.
The Relation Between Job Demands and Safety Attitudes among staff Nurses

Background : Nursing is the backbone of the healthcare sector. They work hard inspite of job demands that cause tension and stress. These demands effect on nurses performance and on their safety. The management should treat staff nurses as a human, give them rest as possible and provide appropriate assignments according to their abilities to help them cope with job demands and achieve safety attitudes. So, the study aimed to investigate the relation between job demands and safety attitudes among staff nurses. Method: descriptive correlational design was used and a convenient sample of (319) staff nurses was included, whom working at Dikirnis General Hospital by using two tools as: job demands and safety attitudes questionnaire. Results: the majority of staff nurses reported moderate level of job demands, more than half of staff nurses had negative perception to safety attitudes, and there was highly statistically significant negative relation between total job demands and total safety attitudes as perceived by staff nurses. Recommendation: Applying of training program for staff nurses continuously on safety issues, how to deal in critical situation, cultural difference and on their area of practice. Development of a favorable work environment by providing sufficient nursing staff and resources to enhance nurses’ ability to deal with work demands and decrease safety risks on nurses
The Association between New-Onset Depressive Symptoms and Participating in Medical Check-Ups among Elderly Individuals

The association between adherence to medical check-ups and new-onset depressive symptoms, after adjusting for comprehensive risk factors such as social characteristics, remains unclear. This study aimed to assess the association between mental health and participating in medical check-ups. The survey data of participants aged 60 to 89 were recruited from the seventh Korean Longitudinal Study on Aging. The primary outcome was new-onset depressive symptoms within 2 years measured using the Center for Epidemiologic Studies Depression Scale. Participating in medical check-ups was defined as undergoing biennial medical check-ups. Multivariable logistic regression was performed to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs) with consideration of a 2-year time lag. Among 4255 participants, the prevalence of new-onset depressive symptoms was 7.36% (n = 313). The prevalence of non-participation in medical check-ups was 11.96% (n = 509). The adjusted OR of new-onset depressive symptoms by non-participation in medical check-ups was 1.65 [95% CI 1.22–2.24; p = 0.001] after adjusting for various demographic, behavioral, occupational, and social participation characteristics. Our findings demonstrated a significant inverse relationship between participation in medical check-ups and new-onset depressive symptoms. It is necessary to monitor and manage depressive symptoms in vulnerable elderly individuals who do not participate in medical check-ups.
Short-Term Effects of Bio-Organic Fertilizer on Soil Fertility and Bacterial Community Composition in Tea Plantation Soils

Overuse of chemical fertilizers to maintain tea production has caused many adverse effects in tea plantations and largely hampers the sustainable development of the tea industry. Applying bio-organic fertilizer (BOF) to achieve the goal of sustainable agriculture has become popular because of its advantages, such as its pollution-free nature, considerable amount of beneficial microbes and soil-friendly organic materials. However, the effects of BOF application on tea plantation soil remain an open question. Herein, we carried out a 3-year pot experiment with four treatments, including control without fertilization (CK), 100% chemical fertilizer (CF), 50% chemical fertilizer +50% BOF (CFOF) and 100% BOF (OF), to explore the effects of BOF application on soil fertility and bacterial community in tea plantations. The results showed that BOF application could increase soil fertility in both bulk and rhizosphere soils and improve the biomass of tea leaves. In addition, the nutrient level change caused by BOF application significantly changed bacterial community diversity and composition and accounted for 74.91% of the community variation. CFOF and OF treatments significantly increased the bacterial Chao1 and Shannon indices compared to CF treatment (p < 0.05). Moreover, bacterial community composition was dominated by Betaproteobacteria (46.88%), Acidobacteria (11.29%), Alphaproteobacteria (9.69%) and Gammaproteobacteria (9.59%). BOF application increased the relative abundance of Alphaproteobacteria, Acidobacteria, Deltaproteobacteria and planctomycetes and decreased the relative abundance of Betaproteobacteria (p < 0.05). Furthermore, bacterial function prediction revealed that BOF application improved the N and C cycling processes and enhanced the co-occurrence network complexity in the bulk soils. Bacterial community functions and co-occurrence networks in the rhizosphere did not show similar results, indicating that rhizosphere bacterial communities were more affected by the rhizosphere effect than BOF application. All these findings verified our hypothesis that applying BOF in tea plantations could increase the biomass of tea plants by improving soil fertility and influencing the soil bacterial function groups. In summary, we suggested that BOF application could be a promising way to achieve the sustainable development of the tea industry.
Survive Amidst the Competition of Private Universities by Maximizing Brand Image and Interest in Studying

Increasing the demand for college provides financial benefits for private universities to survive amid intense competition. The ability to increase interest in college, especially for prospective new students, is largely determined by accreditation, telemarketing, and the university's brand image. The main study in this research is to analyze the brand image model and college interest which is influenced by accreditation and telemarketing. The analytical method in this study uses a Structural Equation Modeling (SEM) approach based on Partial Least Square (PLS). The population in this study was 100 students of class XII in SMA/SMK/Private Aliyah in the city of Medan. The sampling technique used was accidental sampling where 100 class XII students were the main target. Data collection techniques using a questionnaire (questionnaire). The results showed that (1) directly accreditation was not significant to brand image, (2) telemarketing directly had a significant effect on brand image, (3) directly accreditation had a significant effect on college interest, (4) telemarketing directly had a significant effect on interest college interest, (5) directly brand image has a significant effect on college interest, (6) indirectly brand image has no role in mediating accreditation of college interest and (7) brand image indirectly has a role in mediating telemarketing on college interest.
Thin current sheets in the presence of a guiding magnetic field in Earth's magnetosphere

A self-consistent theory of relatively thin anisotropic current sheets (TCS) in collisionless plasma is developed, taking into account the presence of a guiding field By (all notations are used in the GSM coordinate system). TCS configurations with a finite value of guiding field By are often observed in Earth's magnetotail and are typical for Earth's magnetopause. A characteristic signature of such configurations is the existence of a magnetic field component along the direction of TCS current. A general case is considered in this paper with global sheared magnetic field B-y = const. Analytical and numerical (particle-in-cell) models for such plasma equilibria are analyzed and compared with each other as well as with Cluster observations. It is shown that, in contrast to the case with B-y = 0, the character of "particle-current sheet" interaction is drastically changed in the case of a global magnetic shear. Specifically, serpentine-like parts of ion trajectories in the neutral plane become more tortuous, leading to a thicker current sheet. The reflection coefficient of particles coming from northern and southern sources also becomes asymmetric and depends upon the value of the B-y component. As a result, the degree of asymmetry of magnetic field, plasma, and current density profiles appears characteristic of current sheets with a constant B-y. In addition, in the presence of nonzero guiding field, the curvature current of electrons in the center of the current sheet decreases, yielding an effective thickening of the sheet. Implications of these results for current sheets in Earth's magnetosphere are discussed.
ON THE SOLUTION OF PALINDROMIC EIGENVALUE PROBLEMS

A rational eigenvalue problem of the form 1 (A T + •A0 + • 2 A1)x = 0 arising in the vibration analysis of rail tracks under periodic excitation is investigated. This eigenvalue problem is a special case of a more general class of problems referred to as palindromic eigenvalue problems. The paper provides the theoretical background of these eigenvalue problems and proposes a Jacobi-like algorithm for their numerical solution.
Does corruption hinder female political participation? Evidence from a measure against organized crime

This article analyzes the effect of anti-corruption measures on female political empowerment. We exploit a measure that prescribes the dissolution of city councils for mafia infiltration, leading to an exogenous decrease in the level of corruption within local government. We find that the percentage of female councilors and aldermen elected after compulsory administrations, as well as the probability of a female mayor, sharply increases relative to the control group; the effect of the measure is decreasing over time. The evidence suggests that the most likely mechanism mediating the result relies on the reduction in the voter bias against women as policymakers rather than the (self-)selection of women (JEL D72, D78, J16, J71, I38).
Experiences of Migrant People Living with HIV in a Multidisciplinary HIV Care Setting with Rapid B/F/TAF Initiation and Cost-Covered Treatment: The ‘ASAP’ Study

This study aimed to explore the experiences of migrant people living with HIV (MLWH) enrolled in a Montreal-based multidisciplinary HIV care clinic with rapid antiretroviral treatment (ART) initiation and cost-covered ART. Between February 2020 and March 2022, 32 interviews were conducted with 16 MLWH at three time-points (16 after 1 week of ART initiation, 8 after 24 weeks, 8 after 48 weeks). Interviews were analyzed via the Framework Method. Thirty categories were identified, capturing experiences across the HIV care cascade. At diagnosis, most MLWH described “initially experiencing distress”. At linkage, almost all MLWH discussed “navigating the health system with difficulty”. At treatment initiation, almost all MLWH expressed “being satisfied with treatment”, particularly due to a lack of side effects. Regarding care retention, all MLWH noted “facing psychosocial or health-related challenges beyond HIV”. Regarding ART adherence, most MLWH expressed “being satisfied with treatment” with emphasis on their taking control of HIV. At viral suppression, MLWH mentioned “finding more peace of mind since becoming undetectable”. Regarding their perceived health-related quality of life, most MLWH indicated “being helped by a supportive social network”. Efficient, humanizing, and holistic approaches to care in a multidisciplinary setting, coupled with rapid and free ART initiation, seemed to help alleviate patients’ concerns, address their bio-psycho-social challenges, encourage their initial and sustained engagement with HIV care and treatment, and ultimately contribute to positive experiences.
Storms and Precipitation Across the Continental Divide Experiment (SPADE)

The Canadian Rockies are a triple-continental divide, whose high mountains are drained by major snow-fed and rain-fed rivers flowing to the Pacific, Atlantic and Arctic Oceans. The objective of the April-June 2019 Storms and Precipitation Across the continental Divide Experiment (SPADE) was to determine the atmospheric processes producing precipitation on the eastern and western sides of the Canadian Rockies during springtime, a period when upslope events of variable phase dominate precipitation on the eastern slopes. To do so, three observing sites across the divide were instrumented with advanced meteorological sensors. During the 13 observed events, the western side recorded only 25% of the eastern side’s precipitation accumulation, rainfall occurred rather than snowfall, and skies were mainly clear. Moisture sources and amounts varied markedly between events. An atmospheric river landfall in California led to moisture flowing persistently northward and producing the longest duration of precipitation on both sides of the divide. Moisture from the continental interior always produced precipitation on the eastern side but only in specific conditions on the western side. Mainly slow-falling ice crystals, sometimes rimed, formed at higher elevations on the eastern side (> 3 km MSL), were lifted, and subsequently drifted westward over the divide during non-convective storms to produce rain at the surface on the western side. Overall, precipitation generally crossed the divide in the Canadian Rockies during specific spring-storm atmospheric conditions although amounts at the surface varied with elevation, condensate type, and local and large-scale flow fields.
Mountain waves and wakes generated by South Georgia: implications for drag parametrization

High‐resolution simulations of flows over South Georgia (South Atlantic) are used to increase understanding of the likely influence of small isolated mountainous islands on the large‐scale flow and to ascertain the extent to which parametrization schemes can account for the missing drag in models where such islands are only partially resolved. Long‐duration (1 month) austral winter forecasts with a horizontal grid spacing of 1.5 km are used to quantify the mountain‐wave momentum fluxes generated by the island and the low‐level drag associated with flow‐blocking dynamics. The characteristics of the drag, such as the occurrence of high and low drag states, its dependence on wind direction and the spectral contributions to the mountain‐wave momentum flux, are considered. Flow splitting and low‐level wave breaking are shown to be responsible for wake regions that extend for hundreds of kilometres from the island. Regions of deceleration are also evident in the stratosphere, due to mountain‐wave dissipation. The extent to which an orographic drag parametrization scheme can reproduce the drag is investigated by comparison with coarse‐resolution (15 km grid spacing) simulations in which the orography is poorly resolved and a large proportion of the drag is parametrized. It is demonstrated that the total of the resolved plus parametrized drag in these simulations closely resembles that at high resolution, although it is underpredicted during instances of high drag. Simple modifications to the scheme, which enhance the drag when the low‐level flow is approximately normal to the major axis of the subgrid orography, are shown to rectify this. The study demonstrates that, at least for relatively simple isolated mountain ranges, the drag and mountain‐wave momentum fluxes can be predicted in a deterministic sense by a well‐tuned parametrization scheme of suitable complexity, although inclusion of stochastic effects might lead to yet further improvements.
Tidal streams around galaxies in the SDSS DR7 archive. I. First results

Context. Models of hierarchical structure formation predict the accretion of smaller satellite galaxies onto more massive systems and this process should be accompanied by a disintegration of the smaller companions visible, e.g., in tidal streams. Aims. In order to verify and quantify this scenario we have developed a search strategy for low surface brightness tidal structures around a sample of 474 galaxies using the Sloan Digital Sky Survey DR7 archive. Methods. Calibrated images taken from the SDSS archive were processed in an automated manner and visually inspected for possible tidal streams. Results. We were able to extract structures at surface brightness levels ranging from ∼24 down to 28 mag arcsec−2. A significant number of tidal streams was found and measured. Their apparent length varies as they seem to be in different stages of accretion. Conclusions. At least 6% of the galaxies show distinct stream like features, a total of 19% show faint features. Several individual cases are described and discussed.
