4 Tips For Taking Great Vacation Videos
4 Tips For Taking Great Vacation Videos
By Marty HolthausDo you like to make home videos when you go on vacations? If so, then read this article because it is for you. In it you will find some great ideas that can make your next vacation video even better.
1. Wherever you go for your family trip, always try to get some video footage or photos that indicate where it was that you spent your vacation. The idea is to provide both interest and info at the same time. You can show images of road signs, billboards, landscapes and even tourist brochures and local maps. You can then edit all of these images into the rest of the home video on either side of your other footage.
2. One of the most important things to remember is to make sure that you have enough coverage of everyone on your family vacation. Usually the footage of the children is abundant and Mom and Dad are left out. With digital editing, you can always add some still photographs of Mom and Dad but you should try to get the video footage as well.
3. Always aim at getting a few "candid" clips. These are the ones that your family will remember the most. One of the ways that you can try to do this is to carry your video camera around without even taping at first. Keep a little distance from the other members of your family. This may allow your family to feel more at ease in front of the your camera so that when you actually start taping they will act more naturally. If that technique does not work for you, then try turning the camera on, setting it to a wide-angle lens, and then placing the camera in a stable place that can see all of the action. You will need to have the zoom lens wide enough to see all the action.
4. Finally, there are the classic moments. I always look for the classic moments of humor and then try to tape them on video. For me it is when I capture my kids on video at one of those times when they are being too funny. Sometimes the conversation between my two little boys is so crazy that I cannot even hold the camera steadily because I am laughing so hard. Sometimes it will work and sometimes it will not but it is always worth the effort.
Well, these were just a few of my little secrets that I use when taping my own vacation home videos. Use these ideas and you will have lots of success and fun taping your next trip. Good luck!

A Biologist Writes About Large Refrigerators
A Biologist Writes About Large Refrigerators
By John Redman 
Not all large refrigerators get filled with containers that hold food. Sometimes a large refrigerator takes up space in a laboratory, such as one in which scientists and technicians engage in biomedical research.
Such large refrigerators do not hold any eggs or meat, but they could well contain a good deal of protein. In a biotechnology company, technicians and scientists are often asked to collect and isolate the protein from plant, animal or human tissues. Various types of cells are grown in culture, in a special type of medium. Some of the protein produced by the cells makes its way into the culture media.
Media that contains protein from cultured cells is called "conditioned media." It can not be stored at room temperature. If collected media needs to undergo further testing, then it might get stored in a refrigerator. Obviously, the collection of large volumes of any such "conditioned" liquid demands acquisition of a large refrigerator.
Once the gathered media has been tested, then scientists decide whether or not it should be frozen. If protein rich media needs to be frozen, then the media gathering laboratory needs to have access to a large freezer. Some biotechnology companies rely on the availability of walk in freezers. Others use appliances that can keep liquid frozen. A smaller lab might use large refrigerators that have some attached freezer space.
A careful technician keeps close track of all the items stored in any freezer or refrigerator. A technician can never know for sure when someone else in the same research facility might want to test or retest any of the stored liquid. The most useful appliances are those that facilitate development of an organized approach to the storage of large and small volumes of liquid. Of course, no one appliance can satisfy completely the needs of all the laboratory personnel.
Factors to Consider in Buying a Freezer Today
Factors to Consider in Buying a Freezer Today

There are a lot of good reasons to approach the matter of buying a freezer with much thought. When you buy Freezer, it will typically cost you more money than other appliances that can be found in a kitchen like a blender or microwave. Whether you are placing the freezer in your kitchen, basement or garage you will need enough space to house the unit properly.
Before you go ahead and purchase a freezer you must make sure that you are thinking about it carefully. There are many different brands that are very reliable appliances such as GE freezer models or Samsung freezer units. The prices will differ but make sure the one you buy is a quality appliance.
Freezer Capacity
Very similar to refrigerators, freezers that are standalone units will have different size capacities ranging from 200 liters to 1000 liters. Before you make your final decision you will have to think about the following questions:
How many people will the freezer be serving, so to speak? If you are only buying for 2 people, it makes perfect sense to go for the smallest unit. But if you intend to use the freezer for a business, say, a catering one, then a large freezer is in order.
How often do you go shopping to load up the freezer? If you live close to different markets and stores that sell meat or fish you wont really need a large freezer. Although, if you live further away from stores or even towns a larger unit will be better suited for you. Do you at present time have any freezer units in your home? If you are going to be using a new freezer to store food from an already overstocked freezer that you have you will need to figure out just how large or small you will need it to be.
Capacity For Storing
In truth, not all homes out there have enough room in them to house a commercial sized freezer. You must be certain that the unit you wish to purchase will be able to fit into your home safely and properly.
Keep in mind that you have to consider floor, ceiling and wall space, which should be sufficient to allow clearances for air ventilation, easy cleaning and human movement. We suggest measuring the space and then comparing the freezers to it before you buy freezer.
Style Preference
You will have two main selection options when it comes to freezers and those are the chest or upright style. You must base your decision on the pros and cons of each type of freezer that is listed below:
Chest freezers offer more energy efficiency, more storage space especially for the oddly-shaped items and more savings. However, these units also have larger footprints, lesser possibilities for efficient organization of the food, and lesser headroom particularly when placed in areas with low ceilings.
Freezers that stand upright not only cost more to purchase but also are expensive in terms of energy costs. However, you can store and organize your food very easy and pulling the food out of this unit is quite simple.
There are also a lot of handy features that you may wish to have that are worth considering. Features like temperature control, shelves, indicator lights, manual defrost times and many more. Always make your freezer selection based on how much capacity it has and what will suit your needs best.
