Prepare a boiling water bath. Cover the slide with a piece of paper towel and place on staining rack over the water bath. Flood the paper towel on the slide with Malachite Green (primary stain). Steam the slide for 5 to 7 minutes (mordant). After the time is up, carefully remove the slide from the water bath using forceps. Take off papertowel.
Applying a primary stain (crystal violet) to a heat-fixed smear of a bacterial culture. Heat fixation kills some bacteria but is mostly used to affix the bacteria to the slide so that they do not rinse out during the staining procedure. The addition of iodine, which binds to crystal violet and traps it in the cell
Catchment zone in Nattai, Australia containing drinking water. Catchment hydrology is the study of hydrology in drainage basins. Catchments are areas of land where runoff collects to a specific zone. This movement is caused by water moving from areas of high energy to low energy due to the influence of gravity.
The smear is first treated with chloroform to remove fats . Smear applied with Alberts stain which contains cationic dyes such as toluidine blue and malachite green. Toluidine blue preferentially stains granules while malachite green stains cytoplasm. The granules show the typical monochromatism nature, this is used to demonstrate granules
Food grading involves the inspection, assessment and sorting of various foods regarding quality, freshness, legal conformity and market value. [1] [2] Food grading is often done by hand, in which foods are assessed and sorted. [1] [2] Machinery is also used to grade foods, and may involve sorting products by size, shape and quality.
Integrated catchment management recognizes the existence of ecosystems and their role in supporting flora and fauna, providing services to human societies, and regulating the human environment. Integrated catchment management seeks to take into account complex relationships within those ecosystems: between flora and fauna, between geology ...
The thermal mass and conductivity of the element regulate the rate flow of heat into the element. All heat detectors have this thermal lag. Heat detectors have two main classifications of operation, "rate-of-rise" and "fixed temperature". The heat detector is used to help in the reduction of property damage.
Heat Capacity: A fluid’s heat capacity indicates how much thermal energy it can transport and store, impacting the efficiency of the heat transfer process. [ 2 ] Thermal Conductivity and Thermal Diffusivity : These properties influence the rate at which heat is transferred through the fluid, affecting how quickly a system can respond to ...
