This study aims to determine the effect of forest bee honey on changes in male sex sword platy fish (Xiphophorus helleri). The benefits this were appropriate dose for and how survival rate larvae was. was conducted using a completely randomized design (CRD) with five treatments three replications, namely Treatment A: Control (Ordinary Feed), B: Dosage 3 ml mixed into 100 g feed, C: 4 whi...

Platy intergrowths of crystalline todorokite are associated with biogenic debris in the cores of manganese nodules from a site in the Pacific Ocean. Analyses by electron diffraction and transmission electron microscopy demonstrate that this material is composed of tunnels of chains of linked MnO(6) octahedra. The chemical composition, morphology, and stability of the todorokite differ from thos...

a r t i c l e i n f o Mineral particles are used in many industrial applications as fillers, in coatings, as ad-and absorbers or in catalysis. In these manifold fields the particle size and shape control the final performance and properties of the minerals. Much has been published using different techniques to describe the aspect ratio of platy particles. This study describes a simple method to...

USE of a platy internal standard that will orient to the same degree as clay minerals preserves the relative diffraction intensities between the basal reflections from the platy components, regardless of degree of orientation. The method is illustrated with basic zinc chloride and pyrophyllite as the internal standards for quantitative clay mineral anMysis in the systems kaolinite-liVid illite ...
