COULD SXP 1062 BE AN ACCRETING MAGNETAR?

How Dim Accreting Black Holes Could Be?

Recent hydrodynamical simulations of radiatively inefficient black hole accretion flows with low viscosity have demonstrated that these flows differ significantly from those described by an advection-dominated model. The black hole flows are advectiondominated only in their inner parts, but convectively dominated at radii R ∼ > 10RG. In such flows, the radiative output comes mostly from the con...

How the WTO Could Be Improved

AbstractThis paper examines the impasse in the current Doha Development Round negotiations andasks how the rules of the WTO could be changed to facilitate multilateral negotiations andto increase the welfare of the Member countries. It considers possible changes to the methodof negotiation. As examples of rules which are outdated, it considers the rules relating toregional trade agreements and ...

Organic Farming by Using Different Desert Soiles Could it be an Alternative to Fertilizers?

It is shown that Saharan soil has the potential of producing bioavailable iron when illuminated with visible light and also it contains some essential macronutrient and micronutrient elements. In this study, these properties of the desert soil were tested on the certified wheat cultivars (Triticum aestivum L. var. gonen 98) using Hewitt nutrient solution, illuminated and non-illuminated soil so...

Could AX J1841.00536 be an antimagnetar?

Recent observations show that supergiant fast X-ray transients (SFXTs) spend most of their lifetime at an intermediate level luminosity of∼1033–1034 erg−1, and, when a blackbody model for the spectra is adopted, the resulting radii of the emission region are always only a few hundred metres, supporting the idea that during the intermediate state SFXTs are accreting matter from the companion sta...
