Essential Kitchen Cutting Tools

Vegetable Peeler

A short tool with a slotted, swiveling blade used for peeling vegetables and fruits. There are two types: Swiss peeler and standard peeler.

Mandoline

A manual slicer with adjustable blades for creating various cuts, such as julienne, batonnet, and waffle slices.

Sharpening Steel

Used for honing and maintaining knife edges, keeping them sharp with regular use. Not intended for sharpening dull knives.

Sharpening Stone

Also known as a whetstone, used to sharpen dull knives and refine their edges.

Cutting Board

Made of wood, plastic, or composite material, used as a stable surface for cutting, chopping, and other food preparation tasks.

Scissors

Versatile kitchen tool for various tasks, such as snipping herbs,... Continue reading "Essential Kitchen Cutting Tools and Techniques" »

Know what the relationship is between density and temperature

Substances have different densities depending on their temperature.  

For example, a lake on a hot summer day. The surface temperature is warmer than the water beneath. The warm water floats on the cold because it has a lower density. 

Know why your ears pop when you are landing at an airport

Your ears pop from pressure change. The change of pressure outside causes your middle ear to have to readjust, resulting in a popping sound

Know the term buoyancy and why objects sink or float in a substance

Buoyancy is the ability of an object in a fluid to rise or sink due to density differences with its surroundings.

Know the densities of some common substances

Know

To find out whether your vehicle needs oil, follow these steps:

1. Pull out the dipstick and wipe it off on a clean lint-free rag (be sure the engine is cold).
2. Insert the stick back into the pipe.
3. Pull the dipstick out again and look at the film of oil on the end of the stick.
4. Put the dipstick back into the pipe. You're done!

New Distribution Capability (NDC)

NDC forced GDSs to implement more modern data transmission channels to distribute ancillaries to customers.

It is based on a new, single, flexible, and standard language for all air content.

Benefits of NDC

The technology behind this distribution system is planned to generate the following benefits:

1. Encourage innovation, personalization, and brand recognition;
2. Enable further product differentiation and faster time-to-market;
3. Offer travel sellers easier access to real-time, accurate data, rich imagery,
4. Provide exciting new offers created by airlines;
5. Travelers can enjoy more services and a more personalized travel experience;
6. Offer more options for travel sellers (e.g., concert tickets, etc.). More options mean more revenue

He has been a blacksmith for over 30 years and has created weapons for over 200 films. This is Man at Arms.

"The weapons of anime are always my favorite, and I know that the fans have been asking for this for a long time. This is Elucidator from Sword Art Online." He begins by sketching the Elucidator by hand and transferring the design onto 1075 SQT steel. Using a band saw with a bimetal blade, he cuts out the heart of the sword and refines the edges with a belt sander. He marks the internal cut with a soapstone marker and uses a plasma cutter to create the symbol. Another piece, cut from 3/8 gauge carbonized steel, will cover the main section. The edges are leveled, the surface is polished, and any leftovers are trimmed with a Dynafile.

Crafting

At the Beginning

Hello, I'm Laura and I'm going to talk about recycling.

Wood products: include man-made wood and wood derivatives.

man-made wood: properties of natural wood,, it does not look as attractive as natural wood:

plywood (madera contrachapada): formed by an odd number of thin wood layers called venners:example paddles

chipboard (carton de madera): obtained from wood chips mixed with resin: example tables at schools.

wood derivatives: usually obtained from leftover wood:

paper (papel): obtained by forming a paste out of wood and plants fibres: example newspapers.

cardboard (cartón): made by compressing several layers of paper: boxes.

cork (corcho): obtained from the bark of the cork oak: example used in bottle stoppers.

Resistors

• Longer side on positive
• Limit current through circuit
• Measured in ohms (Ω)

Voltage, Current, and Resistance

• Voltage (V): Exerted force to push electricity
• Current (I): Amount of electricity pushed (measured in Amps)
• Resistance (R): Constraints on the flow of electricity
• V = I*R, R=V/I, I=V/R

Diodes

• Act as stop-gap gates
• Ensure electron flow in intended direction

Motors

• Regular DC motors: Spin at various speeds
• Servo motors: Directional control, moving arm from controllable positions

Serial Communications

• Used to print values to Serial Monitor
• Good for troubleshooting

LEDs

• Light Emitting Diodes
• Light up when required forward voltage is found
• Intensity of light depends on current flow

Photodiodes

• Trip to reception of light, not emission of it
• Basics of solar
