An Algorithm for Generating New Mandelbrot and Julia Sets

The present paper is motivated from the paper of John R. Tippetts (Tippetts 1992) in which he gave an algorithm to generate an interesting Mandelbrot set. We not only generate Julia sets using Tippetts algorithm (Tippetts 1992), but also generate some new Julia and Mandelbrot sets by slightly modifying the Tippetts algorithm. This approach yields a new class of algorithms to produce new and alluring fractals with virtually infinite complexity. Keywords: Mandelbrot set, Julia set, recursion formula, algorith

Implication of Air pollution on health effects in Nepal: Lessons from global research

The Nepal Health Research Council and recent National Health Policy of Nepal (2015/16) have included ‘air pollution’ as a priority research/public health agenda that is guaranteed by the Constitution. There is an urgent need to organise the future policies and actions to ensure the commitments to reduce air pollution

Ultrafast adsorption of organic dyes by activated-carbon@Fe3O4 nanoscale composites: An effective solution for water purification

Superparamagnetic (SPM) Fe3O4 nanoparticles (NPs) decorated activated charcoal (AC) skeletal (AC@Fe3O4) type nanoscale composites (NCs) have been prepared by a scalable and facile approach involving impregnation of AC with stable dispersion of SPM Fe3O4 NPs followed by controlled vacuum drying. These NCs exhibit coupled magnetic character and porosity which can be easily optimized by controlling weight ratio of two phases. The electron microscopy images show the presence of clustered Fe3O4 particles present all over the surface of porous AC particles and prevalence of meso-pores, which provides the channels for ingress and immobilization of sorbent moieties. The magnetometry and nitrogen adsorption measurements reveal that magnetic character increases whereas porosity decreases with the increase in Fe3O4 NP loading. These NCs have been demonstrated for purification of water containing methylene blue (MB) dye as an impurity. The porosity of these composites allow rapid adsorption (<1 min) of MB with good removal efficiency (> 99%) and their magnetic behaviour helps in instantaneous separation of MB adsorbed NC particles by the application of external magnetic field. The sorbent can be reused several times after proper regeneration with retention of more than 95% of the original adsorption capacity

Bianchi type-II cosmological model: some remarks

Within the framework of Bianchi type-II (BII) cosmological model the behavior of matter distribution has been considered. It is shown that the non-zero off-diagonal component of Einstein tensor implies some severe restriction on the choice of matter distribution. In particular for a locally rotationally symmetric Bianchi type-II (LRS BII) space-time it is proved that the matter distribution should be strictly isotropic if the corresponding matter field possesses only non-zero diagonal components of the energy-momentum tensor.Comment: 3 page

Renal Transplantation and Pregnancy

Introduction: Although pregnancy after kidney transplantation is feasible, complications are relatively common and this needs to be considered in patient counseling and clinical decision making.Review: Fertility generally returns after renal transplantation. Approximately 74% of pregnancies in kidney transplant recipients end successfully in life births. Published reports suggest that pregnancy has no adverse affects on graft survival although patients with higher pre-pregnancy serum creatinine have a trend toward increased post-pregnancy serum creatinine. There is, however, a significantly increased risk of preeclampsia, gestational diabetes, cesarean section and preterm delivery compared to the general population. Almost half life births are preterm, and low birth weight is very common. Immunosuppressive medications are required to be continued during pregnancy in transplant recipients to prevent graft rejection, except for  sirolimus and mycophenolate mofetil (MMF) which are contraindicated during pregnancy. The incidence of birth defects in the live born is similar to the general population, except for pregnancies exposed to MMF which have a high incidence of birth defects. Every female in the reproductive age group should be counseled regarding pregnancy including the potential risks to the graft, to the mother and to the child. Timing pregnancy should be based upon whether graft function is optimal, but the general recommendation is to wait one year post transplantation before conception.Conclusion: Pregnancy in renal transplant patients should be planned with combined care from surgeons, nephrologists, obstetricians, pediatricians and dietitians which offers the best chance of a favorable outcome in the mother and the fetus
