Modeling and Comparison of Two Geomagnetic Storm
Publication date: Available online 12 November 2019Source: Advances in Space ResearchAuthor(s): Samed InyurtAbstractThis paper is on the investigation and comparison of two consecutive geomagnetic storms in the 24th solar cycle. The first storm is a moderate (Dst=-50 nT) storm occurred on 22.04.2017, while the second is an intense (Dst=-125 nT) storm happened on 28.05.2017. The comparison was carried out based on solar wind (Bz, E, P, N, v, T) and zonal geomagnetic indices (Dst, ap, AE). Mathematical analysis is introduced to the reader with a data set of 9 variables obtained from NASA's observations. The descriptive statistics, demonstrating the power of binary relations with a covariance matrix, hierarchical clustering with a dendrogram, and factor analysis pointing to three separate eigenvectors are the headstone of the discussion. Considering the results, linear models of zonal geomagnetic indices caused by solar parameters are discussed governing the causality principle. Finally, the study ends with a nonlinear model which includes solar wind pressure (P), proton density (N) and ap index. In all analysis, the causality principle is obeyed rigidly and the mathematical models are discussed with the cause-effect relationship.
CONCLUSION: Prevalence of antibiotic use was high not only versus other hospitals in the region but globally including Africa, coupled with significant evidence of sub-optimal prescribing. Swift action is needed to improve future prescribing to reduce AMR. One or two areas should initially be targeted for quality improvement including development of local guidelines, documentation of antibiotic indications and/or stop/review dates.

Authors: Rombauts A, Abelenda-Alonso G, Cuervo G, Gudiol C, Carratalà J Abstract INTRODUCTION: Despite adequate antibiotic coverage, community-acquired pneumonia (CAP) remains a leading cause of hospitalization and mortality worldwide. It induces both a local pulmonary and a systemic inflammatory response, particularly significant in severe cases. The intensity of the dysregulated host response varies from patient to patient and has a negative impact on survival and other outcomes. AREAS COVERED: This comprehensive review summarizes the pathophysiological aspects of the inflammatory response in CAP, brie...
Authors: Hammerschlag MR, Sharma R Abstract INTRODUCTION: Azithromycin was recommended as the first-line therapeutic regimen for treatment of genital infections in men and women by the Centers for Disease Control in 1998. A series of studies of azithromycin for treatment of rectal chlamydial infection in men who have sex with men (MSM) found that azithromycin was significantly less effective than doxycycline. AREAS COVERED: Literature on treatment of rectal C. trachomatis from 2000 through May 2020 was searched using PubMed. Retrospective and observational studies were identified documenting the frequency and t...
Authors: Reissier S, Cattoir V Abstract INTRODUCTION: Streptogramins (pristinamycin and quinupristin-dalfopristin) can be interesting options for the treatment of infections due to Gram-positive cocci, especially multidrug-resistant isolates. AREAS COVERED: This review provides an updated overview on structural and activity characteristics, mechanisms of action and resistance, pharmacokinetic/pharmacodynamic and clinical use of streptogramins. EXPERT OPINION: The streptogramin antibiotics act by inhibition of the bacterial protein synthesis. They are composed of two chemically distinct compounds, namely typ...
