  Abstract
  The present study deals with a spatially homogeneous and anisotropic Bianchi type VI0 space-time in the presence of string of clouds and perfect fluid distribution within the context of gravity. The analytic relation and the hybrid exponential form of the average scale factor have been considered to obtain the exact solutions of highly non-linear field equations. Some physical and kinematical parameters of the constructed model along with the behavior of the equation of state parameter for string fluid are discussed and presented graphically.

  Abstract
  In this article, we have studied the Bianchi-type V cosmological models which are spatially homogeneous and anisotropic in presence of bulk viscous fluid coupled with one-dimensional cosmic string having the constant deceleration parameter. We have obtained the exact solutions of highly non-linear field equations considering linear gravity, the equation of state, and the spatial law of variation for Hubble’s parameter. Some physical and kinematical properties of the constructed models have been discussed and presented graphically and it is interesting to note that the resultant models are in good agreement with recent observations.

  Abstract
  The biochemical and hematological effects of rats fed with vegetables planted on fertilized soil after exposure to sub-acute oscillating magnetic field was investigated. Five different types of soil were sampled along with three types of commonly eaten vegetable plants nursed on two types of fertilizers. Each of the vegetable plants was planted in five local pots, each containing a sampled soil. Other sets of local pots matching this description were fertilized differently with Telfaria occidentalis (Fluted pumpkin), Amaranthus hybridus (Green amaranth) and Basella alba (Malabar spinach) respectively. The control group consists of 3 pots of vegetable plants without fertilizer while the experimental group consists of 6 pots of plants planted with fertilizer. After the vegetables have been matured, they were harvested, dried and grinded into powdered form. The elemental levels in both the soil and vegetables were measured using the Atomic Absorption Spectrophotometer (AAS). Three groups of five rats each were formed from fifteen selected rats. Each group was fed differently with the vegetables harvested from experimental groups, and later exposed to a sub-acute oscillating magnetic field for about 30 days. The animals were sacrificed and the liver was excised for biochemical and haematological analysis. The results show that exposure of rats to magnetic field caused oxidative stress. The accumulated level of heavy metals in the vegetable did not cause significant stress probably due to the presence of bioactive phytochemicals. Data obtained suggest that some haematological parameters of human could be altered if exposed to either sub-acute oscillating magnetic field or consumption of fertilized vegetables.

  Abstract
  Nano-materials are the particles with the both external and internal structural dimensions declining in the range of 1–100nm. Nanomaterials exhibit unique optical, electrical, mechanical, and quantum properties at this scale in contrast to their molecular-scale behavior. In a thorough introduction, the current review describes the methods of synthesis and uses of nanoferrites in a variety of electrical and electronic applications, magnetic recording applications for audio and videotapes, high density digital recording discs, computer memory, antenna fabrication etc and in medical field for cancer treatment and in MRI, in household appliances. The benefits of the Co-Precipitation approach over hydrothermal and sol-gel synthesis procedures for the creation of nanoferrites were the main focus of this review.

  Abstract
  A theoretical study has been done to find crystal field parameters and zero-field splitting parameter of Mn2+ doped SrCl2 single crystals using superposition model and the perturbation theory. The theoretical zero-field splitting parameter D agrees well with the experimental value evaluated from EPR study. The present study supports the experimental result that Mn2+ ions substitute at Sr2+ site in SrCl2 single crystal.
