Two Rainfall-Runoff Models were earlier identified for application and for the generation of a more reliable discharge data. These are the Thornwaite Water Balance Model (WBM) and the IHACRES. The input requirement of both models differ. For the WBM‚ generation of runoff requires seven input parameters. These are the Runoff Factor (RF)‚ Direct Runoff factor (DRF)‚ Soil Moisture Storage Capacity (SMSC)‚ Latitude of location‚ Rain Temperature Threshold‚ Snow Temperature Threshold and Maximum Snow Melt

claim‚ that Falsies can create bigger eyes‚ amplifying lashes 360 degrees‚ is implicit because it cannot be verified. Women are born with varying eye shape and size that mascara alone cannot change. According to Potter‚ there are six different surface criticisms of advertising. This mascara ad contains five of them including‚ manipulation‚ materialism‚ excessiveness‚ stereotyping‚ and deceptiveness. Maybelline stresses that it is a new‚ first-made double brush‚ manipulating us to believe that

The soap disperses in water to form miscelles where a negatively charged surface is formed and hydrocarbon chains are in the centre. These miscelles surround

help us understand better the role of surfactant in the alveolar system. Surfactant is a detergent-like substance produced by the Type II alveolar cells in the alveoli. Surfactant is produced to make it easier for people to breath by reducing the surface tension of the water molecules that primarily compose the walls of the alveoli; it helps them to not stick together. For this experiment‚ we will be using milk and food coloring to represent the water (milk) and gas (food coloring) in the respiratory

Design • Purpose: o To determine how the surface area of a coffee filter affects the average velocity of the coffee filter from the same height. • Variables: o Independent Variable ▪ Surface area- The area of the surface after the folds have been made o Dependent Variable ▪ The Average velocity- calculated by measuring the time and dividing by

GENTLY drop the tissue flat onto the surface of the water GENTLY place a dry paper clip flat onto the tissue (try not to touch the water or the tissue) Use the eraser end of the pencil to carefully poke the tissue (not the paper clip) until the tissue sinks. With some luck‚ the tissue will sink and leave the paper clip floating! How is this possible? With a little thing we scientists call SURFACE TENSION. Basically it means that there is a sort of skin on the surface of water where the water molecules

potato Peanut butter Soft drinks Chocolate coatings Caramels Emulsifiers are molecules that have two distinct ends. One end likes to be in water (hydrophilic) and the other end likes to be in oil (lipophilic). This means that they will coat the surface of oil droplets in an oil-in-water emulsion and effectively ’insulate’ the oil droplets from the water. It keeps them evenly dispersed throughout the emulsion and stops them from clumping together to form their own‚ separate layer. In a water-in-oil
