Extreme ultraviolet emission lines of Ni xii in laboratory and solar spectra
No full textA linear force-free field solution is presented in cylindrical coordinates, formulated in terms of trigonometric and Bessel functions. A numerical exploration has revealed that this solution describes magnetic field lines that meander in Cartesian space, as well as field lines that lie on toroidal flux surfaces. These tori are in (or close to) the plane perpendicular to the cylindrical axis. Nested tori, as well as tori with shells that have finite thickness, were found. The parameter space of the solution shows that the tori exist within a bounded range of values
Numerical simulations of rotating axisymmetric sunspots
No full textA numerical model of axisymmetric convection in the presence of a vertical magnetic flux bundle and rotation about the axis is presented. The model contains a compressible plasma described by the non-linear MHD equations, with density and temperature gradients simulating the upper layer of the Sun's convection zone. The solutions exhibit a central magnetic flux tube in a cylindrical numerical domain, with convection cells forming collar flows around the tube. When the numerical domain is rotated with a constant angular velocity, the plasma forms a Rankine vortex, with the plasma rotating as a rigid body where the magnetic field is strong, as in the flux tube, while experiencing sheared azimuthal flow in the surrounding convection cells, forming a free vortex. As a result, the azimuthal velocity component has its maximum value close to the outer edge of the flux tube. The azimuthal flow inside the magnetic flux tube and the vortex flow is prograde relative to the rotating cylindrical reference frame. A retrograde flow appears at the outer wall. The most significant convection cell outside the flux tube is the location for the maximum value of the azimuthal magnetic field component. The azimuthal flow and magnetic structure are not generated spontaneously, but decay exponentially in the absence of any imposed rotation of the cylindrical domain
Legislative Drafting Guidelines for Africa
No full textThese "Legislative Drafting Guidelines for Africa" aim at providing a set of principles and best practices for drafting primary (original) legislation. In doing so, they provide several general principles that also apply".
These "Legislative Drafting Guidelines for Africa" are intended to promote a commitment to improving the quality of lawmaking and a commitment to simplicity, clarity and consistency in the drafting of laws in Africa.
The Guidelines are neither binding nor exhaustive, and are not intended to override the legislative conventions and official drafting manuals of the respective countries. They can, however, promote a convergence of practices beneficial for the harmonisation of law in Africa. They are intended to serve as a reference for all bodies involved in the process of drafting legislation in Africa.
It is hoped that the Guidelines will assist all those involved, in any way, in drafting legislative acts within the African Union institutions. The Guidelines aim to make African legislation as clear, simple, concise and understandable as possible by providing criteria against which the drafting of legislation may be checked to ensure that its objectives and the means by which they are attained are not only more understandable by citizens but also more easily processed by ICTs.
These Guidelines are divided into three main Parts:
Part I - Introduction that explains the rationale and scope;
Part II - Legislative Drafting Guidelines for Africa that list the drafting guidelines;
Part III - Annex - A glossary of terms used in the Guidelines.
Note: The glossary has included in the Annexes so as not to interrupt the flow of the Guidelines. Nevertheless, the reader is strongly encouraged to read the glossary before or while reading the Guidelines since the terminology used - covering different traditions - may in some respects be different from that which the reader expects

Is geographic diversification sufficient to limit contract grower risk?
No full textLending and financial institutions have looked for a variety of ways to expand their portfolios into agriculture, but because of the risks associated with lending to farmers who lack traditional forms of collateral, they face price and yield risks, causing these inroads to be limited. Market-based instruments are readily available for price risk. Organised exchanges offering the most basic of these instruments, futures and options, have operated for a long time, providing transparency to the market and low-cost risk transfer tools for those able to access them. While the use of price risk management instruments is an incomplete solution, it has sufficient merits on its own and will make the overall burden of risk more bearable. The use of these instruments and multi-peril crop insurance products is expensive and does not provide full protection for financial lending institutions to limit their credit risk exposure. This article determines whether geographic diversification would be sufficient as a risk management tool for lending institutions to limit their credit risk.Geographic diversification, Contract grower, Risk, Lending, Rainfall, Yield, Agricultural Finance,
