In one sentence, describe what the following article is about: The goal is to pack light and only bring what you need, but some trips can be quite long and you may want additional space. If you have to check a bag, find a solid suitcase, either made of durable plastic or with hard sides, to keep the contents from being crushed when it's checked in. If you’re looking for a new suitcase, limit your searches to bags that fit the overhead carry-on space: packing everything into a carry-on will cut down on time spent in check-in lines and the amount you pack. Every airline has their own rule for carry-on luggage, but a bag that is 22”x13”x9” should meet any maximum size limits. Opt for carry-on suitcases whenever possible; you won't have to stand in the check-in lines, and it will make your packing economical. A solid black or navy blue suitcase looks professional and sleek. Choose something that has wheels and an extendable handle so you don’t have to lug it through the airport. Some suitcases have multiple compartments for packing, so you can keep everything separate without using extra items like packing cubes (which are usually zippered fabric cubes that keep all your items organized as you want them, but can add a little extra weight and bulk to your bag). Look for something made from a nicer material - like leather or canvas - in a dark, solid color that has enough room for a laptop, document folder, and electronics. If you already have a carry-on bag, and the airline doesn't allow an additional personal item, find a briefcase or purse that can fit in your suitcase.
Summary: Pick a bag that will fit all your clothes for longer trips. Make sure your carry-on is within the size limit, if you have one. Pick a functional suitcase in a dark color. Find a briefcase or purse that can stay with you throughout the trip.

In one sentence, describe what the following article is about: Cold smoked salmon refers to salmon that is smoked at any temperature lower than 80 °F (27 °C), typically for 15 hours or more. Since the salmon is never really heated, it maintains a lot of its raw textures, and tends to be smoother than hot smoked salmon. It’s most commonly-used on bagels, crackers, or consumed on its own as a simple snack. Cold smoked salmon is often marketed as Nova. Nova is simply short for Nova Scotia, and these cold smoked salmons were caught off of the eastern shores of North America and Canada. Hot smoked salmon is smoked for a shorter period of time at a higher temperature. Typically, it’s smoked around 145 °F (63 °C) for about 8 hours. Since this process thoroughly cooks the salmon, the meat tends to be flakier and firmer, resulting in a final product that resembles grilled salmon. Hot smoked salmon is often used as an ingredient in salads, salads, and casseroles.  Like cold smoked salmon, hot smoked salmon can also be consumed on its own without additional cooking. Hot smoked salmon tends to be smokier than cold smoked salmon. If you’re a fan of barbeque, you’ll love hot smoked salmon. Lox is style of uncooked salmon that isn’t actually smoked, but is often marketed alongside smoked salmon as an alternative. It’s traditionally put on bagels and has a silky texture and salty flavor. Gravlax isn’t smoked either, but is often sold alongside smoked salmon. It’s basically lox that has been cured with spices and seasoning. These are both great alternatives if you want some smoked salmon but can’t find it at your local deli or grocery store.  While these salmons aren’t smoked, their similarity to smoked salmon is unmistakable. You can substitute any recipe that calls for smoked salmon with lox or gravlax. Gravlax is a traditional Nordic dish, but it may be a little harder to get your hands on than lox or smoked salmon. Any Scandinavian recipes that call for gravlax can substitute cold or hot smoked salmon.
Summary: Get cold smoked salmon if you’re looking for a silkier texture. Choose hot smoked salmon if you really love the smoky flavor. Opt for lox or gravlax for a more traditional texture.

In one sentence, describe what the following article is about: While the above conversions took quite a few steps, it is important to recognize that the act of converting from one coordinate system to another is where the "difficult" part is. When dealing with complex numbers purely in polar, the operations of multiplication, division, and even exponentiation (cf. De Moivres' formula) are very easy to do. 3+338+3−338i{\displaystyle {\frac {3+3{\sqrt {3}}}{8}}+{\frac {3-3{\sqrt {3}}}{8}}i}
Summary:
Write out the complex number in standard form.
