T-φ gram Determination of Unreported Meteorological Quantities from T-φ gram 1. Mixing Ratio (W):- It is the ratio of the mass of water vapour to the mass of dry air containing the vapours at a certain temperature. It is expressed in gm/kg. On T-φ gram from dew point temperature we follow isohygric doted green line and read the value at the base. (It can be calculated at all levels where dew point temperature is available). 2. Saturation Mixing Ratio (Ws) :- Mixing ratio at

quite solid‚ neither is it a liquid. Liquid crystals are another important intermediate phase which exhibits features from both the solid and the fluid state. Liquid crystals have the ordering properties of solids but they flow like liquids. Liquid crystalline materials have been observed for over a century but were not recognized as such until 1880s. In 1888‚ Friedrich Reinitzer (picture) is credited for the first systematic description of the liquid crystal phase and reported his observations when

Gram Staining Introduction Prokaryotes are a large group of organisms with no membrane bound organelles. They consist of two domains: Archaea and Bacteria. These organisms are only found in extreme environments such as volcanoes. Prokaryotes are still being researched and are a very diverse group. In this lab we focused on trying to identify if the bacteria found had a lot of peptidoglycan by gram staining. Testing this could be done by using a Petri dish full of agar and testing different bacteria

LIQUID CRYSTALS Introduction What are Liquid crystals ? Its History & Discovery Any of various liquids in which molecules are regularly arrayed like a solid crystal along one or two dimensions‚ but are free in the other dimensions as with typical liquids. Liquid crystals often display unusual and often manipulable optical properties such as anisotropic scattering. They can be divided into two classes‚ Thermo tropic(nematic‚ chiral nematic‚ and smectic.) and Lyotropic. Transitions to thermotropic
