Study of Dark Matter in Context of Recent Observations and Experiments: A study of unexplored part of Universe

The Nature of Dark Matter is still a mystery many theoretical models were proposed but they have problems in explaining the small or large scale structures.A model independent approach by considering dark matter as a fluid is presented in the work which try to find out the binding energy of galaxies...

Functionalized Silica Gel as Metal Scavenger, Sensor, and Catalyst: Designing and Synthesis of Functionalized Silica Gels and their Applications as ... and Catalysts: A Green Chemistry Approach

A wide variety of novel materials can be prepared through the chemical modification of silica gels. In addition to their use in chromatographic separations, they have been increasingly used as catalysts in liquid phase organic reactions. The application of these materials results in viable and ...

Genetic Diversity and Genetic Relationships in Garlic Germplasm: Genetic diversity using Morpho-agronomic traits and Molecular markers (RAPD, ISSR & SSR)

The present investigation was conducted to assess the genetic diversity among 131 garlic genotypes using twelve morpho-agronomic traits and molecular markers at SVPUAT, Meerut, during rabi season of 2014. At the morphological level, ANOVA showed significant variation (p < 0.05) for all traits indica...

Nutrient Indexing of Apple Orchards using Geo-Spatial Techniques: Soil and Leaf Nutrient Spatial Variability Approach for Site-Specific Nutrient Management in Apple

Fertilizers being the costliest inputs, the scientific approaches towards precision Horticulture would imply the use of nutrients according to the actual needs of the soil and crop situations. Geo-spatial techniques thus have much to offer for preparing spatial soil and leaf nutrient maps. Nutrient ...
