The simple toggle switch has long been the standard lighting control option in homes. Most everyone has seen them and they come in a huge variety of decorator finishes. Cover plates are also available in styles ranging from subtle and simple to the outrageous. The rooms were two entrances three-way switches can be more convenient. However, research shows, that even with convenient light switch locations, lights are often left on when rooms are unoccupied. These controls are inexpensive and easy to install, however, there are other options.

Dimmer controls provide variable lighting control. These switches provide some energy savings and were early attempt to reduce the wattage used by light bulb. Dimmers may operate by sliding or returning a knob. Dimmers were developed for incandescent lights, and were relatively inexpensive and easily available.

Timers are often used to give unoccupied houses, a lived in look, and reduce burglaries. However, they are not very effective in an occupied home, because they do not respond to people’s behaviour. Timers may be useful for turning off and on aquarium lights.

Occupancy sensors are becoming more common in homes. They detect activity within a certain area, and turn on the lights automatically when someone enters the room. They reduce indoor lighting energy use by turning the lights are. Soon after the last occupant has left the room. Therefore, the sensors must be located where they will detect the occupants or other activity in all parts of the room. There are two types of occupancy sensors, ultrasonic and infrared.
Ultrasonic sensors detect sound and infrared sensors detect heat and motion. In addition to controlling ambient lighting, they can be useful for controlling task lighting. For example, task lights can be turned on by the motion of the person washing dishes, and then automatically turn off shortly after the person stops. Because of their usefulness, I occupancy sensor technology will continue to improve.

Although the importance of hand washing to preventing sickness has been recognized for a long time, it has garnered special attention over the last five years due to efforts to avoid potential flue epidemics. A vast majority of common infections can be spread by the hands, and hand washing is thus probably the easiest method we know of to prevent sickness. It’s important to instill hand washing in children for two reasons. First, because the habits children learn will, in many cases, be the habits they engage in for their lives. Second, children are already at high risk for infection and may not possess the immune system maturity necessary to fend off pathogens that may not seriously compromise an adult.

One way to build a hand washing habit in children is to start very early. This is part of the thinking behind the installation of portable handwashing sinks in daycares. A portable hand washing station is essentially a move-able sink. Water is stored in the base of the sink, and can be refilled when necessary. A station also can be hooked up to a main water supply if desired. The hand washing station comes equipped with a soap dispenser as well. A portable hand washing station in a daycare draws the attention of children and helps them develop hand washing as a regular habit. It also promotes hand washing among day care employees, whose frequent contact with children makes their cleanliness all the more important.

Proper and regular hand washing is one of the surest ways to prevent infection. The prevalence of new pathogens, and the ease that they spread throughout modern societies makes hand washing all the more important. The installation of portable hand washing stations as daycares may represent a unique way to develop a hand washing habit in young children.

Even if you are a serious hobbyist who knows all aquarium contingencies and has all the necessary tools to clean and repair a decaying aquarium tank, there is need to determine whether your tank is an area of concern. It is actually hard to do this as a problematic aquarium tank can appear very normally. Without the necessary data whether the tank water is suitable for fishes and plants that will be placed in the aquarium, the hobbyist is in for a big headache and worse financial distress. A highly polluted tank water can devastate an aquarium set up in a matter of hours. Fishes and plants will die from bad quality water brought about by bacteria.
A sure way to determine whether the tank water is ideal for fish and plant life is to use pool supplies like water test kits. These are simple piece of device which should be included in any serious hobbyist toolkit. These water testing kits use a chemical powers and liquid solution reagents to determine water quality in any aquarium set-up. These are able to measure the level of ph, alkalinity, nitrite, nitrate leves, ammonia and even excessive algae growth in simple fish tanks. Aside from these test parameters, hobbyists who have marine or reef aquariums also need to monitor calcium, magnesium and strontium levels in the water. Water test results can offer vital information on how you can offset adverse water conditions with additives. Introducing the right additives in your aquarium tanks will keep it at its best condition.

Not everybody can afford to have a swimming pool in their own backyard and if you are one of those lucky few, it is important that you sanitize your pool on a regular basis. No one likes swimming in a pool that is not sanitized. It will still be noticed after some time when health issues arise from visitors and guests.

Sanitization gets rid of bacteria, therefore making swimming safe for everybody. This also prevents the growing of algae in the pool. It is a good idea to test your pool water everyday so that you are assured that it has been disinfected. There are many products that will effectively help you in this task.

You should also keep a record of the schedule of sanitization to avoid confusion. We offer all kinds of sanitization products that will help you maintain a clean and bacteria-free swimming pool.

Around 10,000 years ago, somebody let a primordial barley and hop concoction stand long enough for it to ferment. The result not only made anonymous history, it was the genesis of beer’s own special influence throughout the ages.

It was the accepted practice in Babylonia, as early as 4000 years ago, that for a month after a wedding, the bride’s father would supply his son-in-law with all the mead he could drink. Mead is a honey beer, and because their calendar was lunar-based, this period was called the “honey month” or what we know today as the “honeymoon.” I have also heard that the custom included one of the most resourceful bits of propaganda ever created for husbands. As the story went, if the groom drank mead for an entire moon, it would enhance the chances of his wife bearing a male heir. The bride, however, had to abstain from drinking alcohol at all. I’ll leave the punch lines to you.

After consuming a bucket or two of vibrant brew they called ‘aul,’ or ‘ale,’ a certain self-appointed breed of Vikings would head fearlessly into battle without armor, or even without shirts. In fact, the term “berserk” means “bare shirt” in Norse, and eventually took on the meaning of their wild behavior in battle. They believed that Odin’s favor was all they needed for protection, and if they were to die in combat, it was only because The Allfather decided it was their time to enter the hallowed halls of Valhalla. This was Odin’s great ‘Castle of the Chosen Slain,’ where ‘inductees’ would spend eternity in Viking nirvana, ie- fighting all day, having their wounds miraculously heal at sundown, and then partying all night, with generous quantities of ale at their beck and call.

Before thermometers were invented, brewers would dip a thumb or finger into the mix to find the right temperature for adding yeast. Too cold, and the yeast wouldn’t grow. Too hot, and the yeast would die. This practice is where we get the phrase, “rule of thumb.”

The first known consumer protection act arose with the German Beer Purity Law of 1516, known as Rheinheitsgebot. This decreed that, in order to be called ‘beer,’ a beverage could only consist of four ingredients: malt, hops, yeast and water. This is such a revered regulation that when the European Union facilitated the introduction of other beers into the German market, it took a court order for many stores to sell them. Most of those beers contained preservatives, and to a respectable German, that meant — and still does — that such beverages were not beer. The law also brought forth the introduction to the stein, a beer cup that had a lid for keeping the flies out of the drink. While many beer steins are still popular today with many collectors, many bars and casual drinkers prefer using beer glasses.

In English pubs, ale is ordered by pints and quarts. So, in olde England, when customers got unruly, the bartender would yell at them to mind their own pints and quarts and settle down. It’s where we get the phrase, “mind your P’s and Q’s.”

Also in England’s olden days, pub frequenters often had a whistle baked into the rim or handle of their ceramic cups. When they needed a refill, they used the whistle to get some service. “Wet your whistle” is the phrase inspired by this practice.

In 1740, Admiral Vernon of the British fleet decided to water down the navy’s rum. Needless to say, the sailors weren’t too pleased and called Admiral Vernon “Old Grog,” after the stiff wool grogram coats he wore. The term “grog” soon began to mean the watered down drink itself. When you were drunk on this grog, you were “groggy,” a word that has been expanded to include the effects of too much beer and is still in use today.
