[1] A middleand low-latitude ionospheric theoretical model is used for the first time to assess the effects of the secular variations of geomagnetic field orientation on ionospheric long-term trends over the past century. It is found that the varied geomagnetic field can produce ionospheric long-term trends in both foF2 and hmF2. Since the amplitudes of geomagnetic field change depend on locati...

analysis and the continued success of the moderate islamic discourse on other discourses in turkey in a social environment that nearlya century in the western orientation and secular changes in the basis of social, political and cultural, is the central issue to the most article. this article goes beyond the ideological debates, in the analysis of this fundamental change in this country as a lo...

Abstract We report follow-up observations of the Crab Nebula with PolarLight X-ray polarimeter, which revealed a possible variation in polarization associated pulsar glitch 2019. The new confirm that has recovered roughly 100 days after glitch. With observations, we find angle (PA) measured from total nebular emission difference 18.°0 ± 4.°6 42 yr ago OSO-8, indicating secular evolution either ...

We discuss the basic concept of compartmental modelling in pharmacokinetics and demonstrate that all the solutions admitted by multi-compartment models of classical pharmacokinetics are expressed as linear combinations of exponential functions of time. This lends itself to data analysis that depends on fitting exponential functions to finite size sets. A mathematical method developed a long tim...
