Magnetic properties of exciton trapped by an off-center ionized donor in single quantum dot
Bosch J.,Talbi A.,Baskoutas S.,Feddi E. 한국물리학회 2021 Current Applied Physics Vol.23 No.-
It is known that the lines of exciton (X) and exciton trapped by an ionized donor (D+, X) are often very close which makes very difficult their experimental identification. In order to facilitate their distinction in spherical quantum dots, we investigate the effect of an applied magnetic field studying the binding energy of the complex (D+, X) as function of dot size and the ionized donor position. Our calculation is using a variational approach taking into account the interactions between all charge carriers. Our results show that the complex is more sensitive to the magnetic field than the exciton and that the energy of the exciton is not sufficiently affected when the ionized donor is placed at the edge of the quantum dot. Finally our results are in a fairly good agreement with experimental data and can predict the behaviour law of the diamagnetic effect relating to (D+, X).
REVIEW : The specialist physician`s approach to rheumatoid arthritis in South Africa
( Frederik C. J. Bester ),( Fredricka J. Bosch ),( Barend J. Jansen Van Rensburg ) 대한내과학회 2016 The Korean Journal of Internal Medicine Vol.31 No.2
Rheumatoid arthritis (RA) is expected to increase in Africa and South Africa. Due to the low numbers of rheumatologists in South Africa, specialist physicians also have to care for patients with RA. Furthermore several new developments have taken place in recent years which improved the management and outcome of RA. Classification criteria were updated, assessment follow-up tools were refined and above all, several new biological disease-modifying anti-rheumatic drugs were developed. Therefore it is imperative for specialist physicians to update themselves with the newest developments in the management of RA. This article provides an overview of the newest developments in the management of RA in the South African context. This approach may well apply to countries with similar specialist to patient ratios and disease profiles.

Should Male Circumcision be Advocated for Genital Cancer Prevention?
Morris, Brian J.,Mindel, Adrian,Tobian, Aaron A.R.,Hankins, Catherine A.,Gray, Ronald H.,Bailey, Robert C.,Bosch, Xavier,Wodak, Alex D. Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.9
The recent policy statement by the Cancer Council of Australia on infant circumcision and cancer prevention and the announcement that the quadrivalent human papillomavirus (HPV) vaccine will be made available for boys in Australia prompted us to provide an assessment of genital cancer prevention. While HPV vaccination of boys should help reduce anal cancer in homosexual men and cervical cancer in women, it will have little or no impact on penile or prostate cancer. Male circumcision can reduce cervical, penile and possibly prostate cancer. Promotion of both HPV vaccination and male circumcision will synergistically maximize genital cancer prevention.

Our results confirm that HPV plays a major role in the development of cervical cancer and provide the scientific basis for setting up new preventive strategies using the HPV vaccines which are under development.

<P>In 2011, Lake Erie experienced the largest harmful algal bloom in its recorded history, with a peak intensity over three times greater than any previously observed bloom. Here we show that long-term trends in agricultural practices are consistent with increasing phosphorus loading to the western basin of the lake, and that these trends, coupled with meteorological conditions in spring 2011, produced record-breaking nutrient loads. An extended period of weak lake circulation then led to abnormally long residence times that incubated the bloom, and warm and quiescent conditions after bloom onset allowed algae to remain near the top of the water column and prevented flushing of nutrients from the system. We further find that all of these factors are consistent with expected future conditions. If a scientifically guided management plan to mitigate these impacts is not implemented, we can therefore expect this bloom to be a harbinger of future blooms in Lake Erie.</P>
