To investigate the formation mechanism of relativistic jets in active galactic nuclei and micro-quasars, we have developed a new general relativistic magnetohydrodynamic code in Kerr geometry. Here we report on the first numerical simulation of jet formation in a rapidly-rotating (a = 0.95) Kerr black hole magnetosphere. We study cases in which the Keplerian accretion disk is both co-rotating a...

This article discusses the results of a literature review that has assessed the impact of Female Genital Mutilation (FGM) legislation in 28 countries (27 in Africa and Yemen) where FGM is concentrated. Evidence on the impact of FGM legislation was available on prevalence of FGM; changes in societal attitudes and perceptions of FGM; knowledge and awareness of FGM legislation and consequences, an...

We consider the linear global stability of the boundary-layer flow over a rotating sphere. Our results suggest that a self-excited linear global mode can exist when the sphere rotates sufficiently fast, with properties fixed by the flow at latitudes between approximately 55°–65° from the pole (depending on the rotation rate). A neutral curve for global linear instabilities is presented with cri...

The issue of whether medical practitioners should perform "ritual nicks" as a method of meeting demand for female genital mutilation (FGM) has recently been debated in the United States and Australia. Due to increasing numbers of people arriving and settling in Australia from African nations in which FGM is customary, demand for FGM in Australia is present and may be increasing. Australian law ...

The structure and magnitude of the electromagnetic field produced by a rotating accretion disk around a black hole were determined. The disk matter is assumed to be a magnetized plasma with a frozenin poloidal magnetic field. The vacuum approximation is used outside the disk.

Female genital mutilation (FGM) is almost always performed on children and consequently paediatricians should have a central role in the detection and prevention of FGM. FGM has no health benefits and can cause lifelong damage to physical and psychological health. Extensive migration of FGM practising communities means that FGM is now a global problem. Paediatricians worldwide need to be famili...

Nigeria, due to its large population, has the highest absolute number of female genital mutilation (FGM) worldwide, accounting for about one-quarter of the estimated 115-130 million circumcised women in the world. The objective of this review is to ascertain the current status of FGM in Nigeria. Pertinent literature on FGM retrieved from internet services [Google search on FGM in Nigeria, www.o...

BACKGROUND The physical and psychological impact of female genital mutilation / cutting (FGM/C) can be substantial, long term, and irreversible. Parts of the health sector in Australia have developed guidelines in the management of FGM/C, but large gaps exist in community and professional knowledge of the consequences and treatment of FGM/C. The prevalence of FGM/C amongst Australian women is u...

A single merger scenario for making galaxies such as NGC 4550 possessing equal coplanar counter-rotating stellar disks is investigated by collisionless N-body technique. The scenario is successful in producing an axisymmetric disk made of two almost equal counter-rotating populations. The final disk shows a clear bimodal line profile in the outer part, which demonstrates that disk-disk mergers ...
