The use of a HY-lite 2 system in microbiology?
HY-LiTE is a portable hygiene monitoring system for control of cleanliness in food and beverage production. Clear results within only one minute leaves time enough to clean again and to make sure, that everything is really clean before production starts.Surfaces in food production like cutting boards or slicing machines, which bear risk of endangering a complete lot of food product, should be controled by HY-LiTE routinely. Rinse water samples from cleaning in place (CIP) procedures in tanks or filling heads should also be checked regularly. HY-LiTE 2 is better and fasterHY-LiTE detects adenosine triphosphate, the ATP, which can be found in all kinds of food debris and cellular residues.The unique firefly reaction, also used by fireflies glowing in the dark, is used by HY-LiTE to detect ATP rapidly and accurately, even in the smallest amounts.Now, with an improved luminometer, the HY-LiTE 2 system, an already excellent method has been even further improved. It combines the speed of visual checks with the reliability of a sensitive analytical method.Because measurements and trend analysis can be done outside the laboratory, immediate action - as recommended by opinion leaders and guidelines - can be initiated before production starts. HY-LiTE provides peace of mind and may even avoid loss of reputation and loss of confidence in your products.
What are the modern tools and techniques in biology?
1. Magnifying Glass - it is used to produce a magnified image of an object2. Petri Dish - it is used for holding a culture medium upon which cells, bacteria and viruses can be grown and studied3. cover slip - it is a protector that goes over tissues with mounting media, this keeps the tissue on the slide from degrading4. thermometer - it is used for measuring temperature or temperature gradient using a variety of different principles5. test tube - it is used by chemists to hold, mix or heat small quantities of solid or liquid chemicals, especially for qualitative and experiment and essays6. microscope - it is used for viewing objects that are too small to be seen by the naked eyes7. funnel - it is used to channel liquid or fine-grained substances into containers with a small opening8. dissecting pan - it is a pan where you dissect organisms so the organs or fluid wont spread away.9. glass slide - it is used to place an item on and put it under a microscope to view10. medicine dropper - it is used to measure small amount of liquids usually in milligrams11. dissecting scissors - it is used for slicing a specimen during dissection12. forceps - it is used for grasping, manipulating or extracting, especially such an instrument used by a surgeon13. scalpel - it is a fixed blade used in surgery and dissection14. beaker - it is used as a laboratory container and mixing jar15. test tube rack - it is used to hold the test tube so the solution/substance in it wont spread away16. dissecting pin - it is used to hold open the specimen that you're dissecting17. meter stick - its a stick that is 100 centimeters long, roughly 39 inches. Generally used to measure distance.18. Bunsen burner - it is commonly used in scientific laboratories, consisting essentially of a hollow tube which is fitted vertically around the flame and which has an opening at the base to admit air.19. graduated cylinder - is a piece of laboratory equipment used to accurately measure out volumes of objects for use in labs.20. triple-bean balance - it is used to find the mass of an object21. safety goggles - it is used as protection of eye from dust, flying debris, chemical splashes, etc.22. pipette - A piece of laboratory glassware, shaped like a thin tube with a bulge in the middle, that allows better accuracy when measuring certain volumes (hence the range of sizes) e.g. when making solutions or samples for titration.23. probe - its a slender surgical instrument for exploring the depth or direction of a wound, sinus, or the like.24. safety mask - its a mask used when doing experiment, dissection or surgery to protect us from poisonous gasses, viruses and dustsRead more:http://wiki.answers.com/What_are_the_biological_tools_and_their_function#ixzz1ReeXUBziUngsa techniques kayo na bahala dun
What is the present tense of slice?

What two cross sections are possible when slicing a square pyramid vertically?
A trapezium or a triangle. If the pyramid is a right pyramid then they would both be isosceles.
What is a plane figure obtained by slicing a solid with a plane?
That depends on the solid that you are slicing.If the solid is a cylinder, you can make a circle by slicing horizontally,or an ellipse by slicing diagonally.If the solid has a square "base", then you can make make squares,rectangles, and even hexagons.If the solid is a cone or better yet a double cone, you can constructthe conic sections (circle, ellipse, parabola, hyperbola).===================================Answer #2:The tidiest answer to the question is: A "section" is.
What is precision microtome?
A device for slicing ultra thin slices, called sections - hence sectioning - from a solid block of sample for viewing under microscopes. They used to be precision, but the latest is ultra-precision: current models can and do section at the level of 20,000 sections per millimeter!
When was Slicing Grandpa created?
Slicing Grandpa was created in 1993.
What are the four kinds of parabolas?
Conic Sections are figures that can be formed by slicing a three dimensional right circular cone with a plane. There are different ways to do this, and each way yields a different figure. These figures can be represented on the graph as well as algebraically. The four conic sections are circles, ellipses, parabolas, and hyperbolas.

Is slicing a bread a chemical or a physical?
Slicing bread is a physical change, because each slice of bread has the same chemical composition as it had before it was sliced.
