Mosquito repellent Television Set
South Korea`s LG Electronics Inc, Indian`s arm has launched and begun sale of a mosquito repellent television sets. The TV is the LG 32LH520D. Contrary to expectations the big features of the TV is not more resolution or smart functionality or even screen size. The big feature with this TV set is that it has technology inside that should be able to repel mosquitoes.
Mosquitoes are a menace in most parts of the world thanks to the numerous and potential diseases and infections they can spread including Zika, dengue and the ever deadly Malaria. The new TV set generates ultrasonic sound waves which repel mosquitoes as they hate the sound. Since the sound waves are inaudible to the human ear, they do not bother viewers.
The Mosquito Away technology, certified to be effective has been used by LG in washing machines and Air Conditioners. The technology has the capability to perform even when the television set is turned off.
LG were to quick to remind us that this technology is not meant to replace other forms of mosquito repellent.

What Is Lighting Pollution?
There is a story about a town that there was a day without Electricity at night and the residence noticed some bright strange patterns in the sky, They dialed 911 and reported the `UFO' to the police. On arrival, the police never saw the `UFO' but a bright sky dotted with various patterns of the milky way. Apparently, the residence had mistaken the milky way with a `UFO'. This is as a a result of excessive use of external artificial lighting. Many years back you would enjoy a spectacular view of the starry sky. Well, That is no more because of Light pollution.
 |
| That Is Too Much Lighting, yeah? |
Light pollution can simply be defined as excessive and inappropriate artificial light. Too much of light pollution washes out view of the Universe, result in increase in the energy consumption, interferes with astronomical research, disrupts ecosystems, affects the health and safety of humans and wildlife to mention but a few effects of Lighting pollution.
What Are Sources And Types Of Light Pollution?
1. Urban Sky Glow

| Calgary, Canada. A Good Example Of Sky Glow |
2. Light Trespass.
One or two of you have missed a good night sleep beacuse of very bright light from wherever, street light may be, was illuminating directly into your bedrooms. That was a goo illustration of Light trespass which means light falling where it is needed, intended to or wanted. Spill light is the most subjective form of light pollution because there are no guidelines to determine when, where, or how much light is unwanted. A common example of spill light is light from a streetlight coming through a window and illuminating a bedroom or light from a neighbor's floodlight or security light shining over the fence and illuminating your property.

Choosing A Lighting Fitting?
Although picking a light fixture might seem like a pretty standard task, today’s numerous options make this once-easy decision more complicated. No matter how mundane it might seem, picking the right illumination is important. Some light fixtures cover very little ground and provide more of an ambient glow, while others shine from one corner of the room to another. Choosing the wrong fixture can lead to a poorly lit room or even an overly lit, washed-out space. Poorly lit or overly lit spaces are also a health risk and in worst case scenarios can lead to loss of eyesight.
Here are a few options to consider before making a choice on that particular light fixture in your mind:-
1.Pendant Lights
A pendant light is a smaller fixture suspended from the ceiling by a cord, chain or metal rod. Pendant lights traditionally include only one light bulb, so they don’t cover as much ground; several are often used to cover more space. There are many styles, including drum pendants and globe pendants, making it easy to find one that will fit your decor. They work well when you’re trying to showcase a smaller, specific area, such as a kitchen island or a dining area.
 |
| A Set Of Pendants |
2.Chandeliers
Chandeliers have as many light bulbs combined in one unit to create a larger, more dramatic statement piece. Unlike pendants, they produce a stronger glow and therefore can often stand alone. Chandeliers are traditionally more elegant and more expensive than other fixtures, and therefore are used less frequently — you may see one in an entryway or a formal dining room.
 |
| A Crystal Chandelier |
3.Ceiling Fans
Did you know that the ceiling fans can also light up your room? Well, it is not the fan that does the lighting but they are fitted with lighting fittings.
Fans are primarily used for practicality as opposed to beauty. Ceiling fans are a great way to cool a room down and in recent times brighten it up at the same time. They are often used in bedrooms, though they come in handy where there’s a lot of activity, including playrooms and home gyms.
 |
| Ceiling Fans Fitted With Lighting Fixtures |
4.Wall Sconces
Mostly used for adding ambiance and decoration, a wall sconce is any kind of wall-mounted light fixture. It provides dimmer, less vibrant illumination and is therefore likely to be used in multiples down a hallway, staircase lighting or near a front door.
 |
| A Beautiful Wall Sconces |
4. Recessed Lighting
This is a great source of additional lighting especially in spaces with lower ceiling levels. If space is an issue, recessed bulbs are a great option, because they take up no space at all; a fixture is inserted directly into the ceiling. Because they are often used as accents in a larger space, such as a kitchen or living room, recessed bulbs are almost always used in multiples. Although not as common a use, they can also be inserted into floors and walls to provide additional brightness in dark spaces.
 |
| Recessed Lighting Complementing A Chandelier |
5.Cabinet Lighting
These fixtures are mounted underneath a cabinet or shelf and provide illumination for a particular task. They are most often placed in kitchen cabinets to act as pinpointed spotlights for cooking, but they can also provide accent brightness for home office or living room shelves. They can also provide much needed light in a dresser or wardrobes.
 |
| Under cabinet Lighting |
6.Track Lighting
Like a chandelier, this lighting source includes several light bulbs in one fixture, but instead of being grouped together, the bulbs are strung along a horizontal track. Tracks are a more casual way to get a lot of illumination in one space, and therefore they look good in less formal settings, such as a hallway, an office or a kitchen. Most of them can be positioned to highlight specific areas, which makes them great for showcasing artwork. Note; The tracks are also available in various shapes i.e circles, polylines
 |
| Track Lighting |
7.Floor or Table Lamps
If you’re looking for a more traditional fixture, you can always opt for floor lamps or table lamps. Because of their many different shapes, sizes and designs, they are often a great way to add some flavor to your living room or bedroom. Lampshades are easy to switch, so if you’re looking for a fresh, new look, you can change them out as often as you like. In addition, they are also the easiest to install as they come fixed with a plug and all you need is a powered socket outlet.
 |
| Floor Lamps |
This is just but a few of the many light fitting options available for your choosing in the market. Remember to talk to as many suppliers before you make a final decision on the light fitting you would wish installad in your premises.
We hope you have learnt something and you are more than ready to make a choice. Stay tuned and engage us for more on Building Services Engineering

Electricity man?
Electric shock happens when current is made to flow through your body. The effects range from a sensation through your body to fatalities. However, there is an individual who can withstand as much as 30 times the current which will kill a normal person. Meet Raj Mohan Nair
 |
| Raj Mohan Nair |
He is well known around for his supernatural abilities passing massive current through his body to power up a bulb or even an Electric blender. He does this by touching both ends of a LIVE wire which could be prove fatal should they be touched by me or you - normal people. He puts one end of the wire on his tongue for better conductivity and the other end on any part of his body allowing current to pass through his body powering the connected device.
 |
| And the bulb was on - through his body! |
Are you asking how he discovered his special gift? Well, Mohan discovered his supernatural abilities from suicidal attempt when he tried to kill himself by hanging on to a transformer, you guessed it right, nothing happened. Raj lost his mother when he was just seven leading to frustrations and broken heart thus the suicidal attempts.
It is impossible for any normal person to withstand that much current. So, what makes him endure this?Measurements of his body`s resistance to Electricity revealed that he is ten times more resistant compared to an ordinary human being. He is a supernatural being, thinking of a comic book?

How Do Rolling Shutter Work?
You have that neighbor whose garage door opens whenever he appears or when he presses a button form a remote control device and you wonder how he does that? Well, you dont have to worry anymore as we share with you how the rolling shutter works?
 |
| A Closed Roller Shutter Door |
This can also be referred to as a roller door or a sectional overhead door. This is a type of door made up of horizontal metal slats guided in a track operating by raising to open it up and lowering to close it. This can be manually or automatically operated. They are applied in garage doors, keeps most stalls safe, protect windows from extreme weather conditions like hailstorm and even any form of burglary.There are also just as many varieties of rolling shutters in the market.
What Are The Components Of Rolling Shutter?
1. Cheek plate - Secured to the building structure, they support the roller holding the curtain in place is supported by two load-bearing cheek plates (also known as end plates).
2. Flag post - The cheek plate is either welded to a vertical angle or directly to the top of the guide giving the look of a flag post. This is secured to the building structure to give additional support and aid the installation of the shutter.

 |
| Cheek Plate And Flag Post |
3. Roller assembly - The shutter curtain is held in place by a full width roller, which is supported at each end by the cheek plates. The roller comprises of a steel tube with a tubular motor fitted at one end and a shaft at the opposite end.
4. Tubular Motor - A tubular motor is fitted into the shutter's overhead barrel assembly. Protruding from the barrel is the motor head which incorporates a manual override eye (when a manual override facility is included), the electrical wire feed, and a pair of limit switches to control the maximum travel distance of the shutter curtain. The motor is fitted with an operational brake to hold the shutter stationary when it is in its upper position.
5. Safety Brake - This centrifugal brake arrests the descent of the shutter if there is a failure in the motor. If the motor's operational brake fails to hold the shutter stationary when it is in its upper position, or the shutter descends at an uncontrolled speed, the safety brake will activate and bring the shutter to a complete halt. Some units also have a micro-switch that will disconnect the motor from the electrical supply. The brake, once activated, will need to be reset or in some cases, replaced. An experienced shutter engineer must carry out resetting or replacement. In addition, U- Cup or Bearing is fitted to the cheek plate to support the barrel.
6.Guides - The curtain runs up and down through two side guides. These are 'u' shape in design.
 |
| Materials Used To Make The Roll And Shutter |
8. Bottom Rail - The final bottom section of the curtain and is often 'T' shaped or 'L' shaped to give additional rigidity.
9. Canopy Cover(the hood) . The fitting of this is generally optional. It is made of galvanised steel and is supplied folded to wrap around the cheek plates protecting the curtain and barrel from the rain and dust. It is also a safety requirement when the roller mechanism or motor is below 2500mm high.

Fire Extinguishing Ball
Did you know that 90% of people do not know how to use or operate fire extinguishing equipment when faced with such a situation? In addition, many are untrained on effective use of the equipment, most of equipment are not sizable but bulky to carry and aim at fire, many also fear the exposure to smoke and heat and MOST are those that panic and take to their heels forgetting how to use such equip when faced with fire problems. Ever thought of an equipment which you could just place in a fire prone area and the problem is taken care of? Well, here comes the FIRE EXTINGUISHING BALL
 |
| A Simple Illustration On How To use A Fire Extinguisher |
Fire Extinguishing Ball
An Israeli company Elide has invented a ball that puts out fire by being thrown onto the source of fire or by just being near the fire. We share with you a video demonstration of how this ball works.The ball is filled up with chemicals that puts out all classes of fire and it will take only three seconds to activate meaning fire can be taken care of before any further spread of the fire could happen. The ball has aloud noise which acts as an alarm alerting you of fire. This can be used easily by anyone of any weight category including children as it weighs three pounds only. As explained in their website, the chemicals are non-toxic to the environment as they are made from human and environmentally friendly materials.
This can be mounted on fire prone areas like the kitchen and also with its small size it can fit in any accessible space in your home or office. This should be used as a stp gap measure as the chemicals can only go as far and thus the other mainstream fire equipment should be installed and made available.

How To Protect Yourself from Lightning?
Did you know that an estimated 24,000 people are killed by lightning strikes around the world each year and about 240,000 are injured? Knowing how to protect yourself and your property could be the difference between Life and Death. Before we discuss on the different Lightning Protection systems, we share with you simple but effective ways to protect yourself from lighting
 |
| A Lightning Strike |
Perhaps the most basic definition of Lightning: the occurrence of a natural electrical discharge of very short duration and high voltage between a cloud and the ground or within a cloud, accompanied by a bright flash and typically also thunder.Lightning is an electric current. Within a thundercloud way up in the sky, many small bits of ice (frozen raindrops) bump into each other as they move around in the air.

| So, this guy can withstand over 300 kV? |
How Do you Protect yourself from lightning?
In general, it seems quite easy to shelter from the rain under the eaves of a house. And many people believe that they will be safe inside a building. However, when lightning (electrical current) flows through an object, most of the current flows along the surface, with only a little through the center, in what is known as a skin effect. This means that eaves and the sides of pillars can be dangerous.
Here are basic but effective ways to protect yourself from lightning?
1. Avoid using any plumbing during lightning storms. If lightning strikes your home or building, or other nearby locations, it can impart an electrical charge to the metal pipes in your plumbing, which lead to electrocution if you are using the plumbing connected to those pipes.
2. Avoid using your corded landline telephone during lightning storms. If lightning strikes the main phone line in your neighborhood or outside your home, the electricity from the strike will travel through every phone connected to the line, and electrocute anyone using the telephone.
3.Don't use appliances that are plugged into the wall during lightning storms. Appliances that are plugged into the wall and turned on can be dangerous for you to use if lightening strikes your home or the power line it is connected to.Turn off televisions, computers, air conditioners, and other appliances that are plugged in and running during lightning storms.
4.Avoid standing on surfaces in which moisture or water is present during lightning storms. Electrical currents will travel through the ground where water is present, and can electrocute anyone in contact with these surfaces. Examples of surfaces to avoid are basement floors, patios, garage flooring, and other flooring where water and other moisture may be present.

| A Beautiful Danger |
5. Do not lean on or sit against walls during lightning storms. Sometimes lightning can reach the electrical wiring in walls, which can cause you to become shocked or electrocuted if you are pressed against a wall.
6. If you're caught in a storm and cannot get to a shelter, put your feet as close together as possible and crouch down with your head as low as possible without touching the ground. By making your body as low to the ground as possible and minimizing the amount of contact your body has with the ground, you will lessen the risk of a lightning-related injury
7. Very basic but perhaps most important: If you're outside keep an eye on the weather. Look for darkening skies, flashes of lightning, or increasing winds. Lightning often precedes rain, so don't wait for rain to fall. And if you hear thunder, go inside immediately.Prevention is Better Than Cure, remember that old saying?
In the spirit of prevention in our next article, we will discuss Lightning protection systems that can be installed on your property to protect yourself and your loved ones from this Beautiful yet deadly natural phenomena.

Kitchen hazards - How Safe Is Your Kitchen?
Did you know that kitchens are the most dangerous room in houses, hotels and restaurants?For many people, the kitchen is a well-loved part of the home. It is here family meals are lovingly prepared and family recipes are passed down the generations.It is also a place where accidents can occur easily if some common hazards are not recognised and addressed. This is pertinent for young children or the elderly and everyone in the household should play a role in maintaining safety in the kitchen.
 |
| A Clean Safe Kitchen |
Here are the common hazards you should be aware of:
Fires – This is one of the more obvious hazards since stoves and ovens are always lit with fires and yet, it’s one of the biggest accidents to happen in the kitchen! Long or loose fitting sleeves can catch a flame or perhaps have some drops of oil on the wrist area causing it to become a flammable torch rather than a protective barrier
 |
| How Fire Spreads In A Kitchen? |
Hazmats – Certain chemicals kept in the kitchen are hazardous.Some of these products are hand sanitisers, cleaning liquids, certain oils and pesticides that are used in the kitchen for obvious reasons but should they accidentally get mixed with food it could cause serious side effects.
 |
| Did She Fall? Let us hope not... |
Cooking gas - Gas stoves provide cooking flexibility, they emit chemicals that are harming your health. Studies have shown that gas stoves give off unhealthy levels of noxious combustible by-products.
HOW TO BE SAFE IN THE KITCHEN
We share with you tips which are simple things to do, yet they can go a long way to ensure that the kitchen remains a safe environment for all members of the family.
1.Install non-slip flooring materials and mats to prevent employee or even your Loved ones at home from slipping if the floor becomes wet or slippery. Always clean floors immediately after a spill to reduce hazards.
2.Use sinks and cooking equipment that prevent water, oils and fats from escaping. Also, require employees to wear non-slip footwear designed for kitchen areas. Another hazard involving floors is uneven surfaces.
3.Install a small ramp over the uneven part of the floor to make a smooth transition or paint the uneven part of the floor with brightly colored paint to alert everyone to the danger of tripping.

Need To Put Out A Fire? Here Is How...
Some play with it, we cook with it, warm ourselves with fire, we get rid of our wastes with fire; there is an endless list of activities we carry out with fire. In addition, Fire also occurs from our very own carelessness, accidentally from faults of our day to day appliances, intentionally especially by arsonists and sometimes we play too much with it and you know what happens when you play with fire, yeah?
 |
| Let Us Assume He Is An Expert... |
What happens when a fire occurs? How do you put out fire caused by an Electrical fault? In this piece we share with you the different types of fires and subsequent ways of effectively dealing with them. You will stop stumping on fires with your feet, we hope?
Types Of Fire
Fire is classified based on the fuel they burn which basically means the method of putting them out should also be different. We share with you the different classes of fire and the means of putting them out:
1. Class A Fires
These are fires caused burning on solid objects such as trash, paper, wood and plastic. Basically anything that burns to ashes. These can easily be put-off with water and foam.
1. Class A Fires
These are fires caused burning on solid objects such as trash, paper, wood and plastic. Basically anything that burns to ashes. These can easily be put-off with water and foam.
 |
| Class A Fire |
2. Class B
These are caused by flammable liquids such as gasoline, petroleum oil or even paint. This includes flammable gases as well. These are well dealt with carbon dioxide extinguishers. They do away with the oxygen element of the fire triangle and the heat because of a very cold discharge. Chemicals such as monammonium phosphate and sodium bicarbonate.
 |
| Class B Fire |
3. Class C
These are fires involving Electrically energised equipment such as Transformer, generators and Electrical appliances. You should never use water to put off these kind of fires for the fact that water conducts electricity and you may be Electrocuted leading to serious injuries or even fatalities. Once the source of power is put off, you will be able to use any kind of extinguisher to put off this kind of fire.
 |
| Electrical Fire |
4. Class D
These are fires with combustible metal element such as potassium, sodium, aluminum, and magnesium. How do you put off these kind of fire? These are dealt with effectively with dry powder. They work by smothering and heat absorption.
 |
| Class D Fires |
5. Class K
Ever tried to fry some of your favorite meals and fire comes out of nowhere? Well, that is a class K fire. These are fires that involve cooking oil , animal fat or grease. These are dealt with effectively with purple K.

| Class K. |
 |
| Fire Extinguishers And The Color Codes |
The best way to be safe from fire is by prevention. You should indulge the services of a qualified person to ensure systems are put in place to prevent fire incidences or at least be dealt with automatically. YOU SHOULD BE CAREFUL AROUND FIRE AS WELL.

What Is A Lightning Protection System?
Once you learn how to protect yourself from Lightning, how do you prevent this phenonmena from hitting your property or your Electrical equipment? When lightning strikes,everything is in danger including your equipment, appliances, structures and anything matter around the charged area. This calls for a system to be put in place not only to protect you and your loved ones but your structure, equipment and appliances as well. What is a lightning protection system and how does it protect you?
 |
| A Building Fitted With A Lightning Protection System |
This is a passive means of preventing property damage from the effects of a lightning strike. Lightning protection systems act like a Faraday Cage for buildings. Protecting the building and its contents from external electric fields by migrating that energy around the cage instead of through its contents.The low resistant path offered by a lightning protection system is very important as high voltage currents from a lightning strike will always take a path of least resistance to ground. There are four main parts of a properly installed lightning protection system: copper air terminals, copper cable, copper clad ground rods, surge suppressors.
Components Of A Lightning Protection System?
b) Down conductors/Conductor cables
These are heavy cables or copper tapes that carry lightning current from the air termination rods to
the ground.
 |
| Copper Cable Is The Down Conductor |
They should take the most direct
route from the air termination rods to the earth termination system. Even though, down conductor positioning and distancing is often dictated by architectural constraints, there should be one down conductor for every 20m or part there of of the building perimeter at roof or ground level evenly spaced and distances apart of more than 20m avoided if possible. Reinforcement or structural metal work can be used as down conductors but only after the electrical continuity is ascertained from the air termination system to the earth termination systems
(c) Earth Termination Systems/Earth rods
Long, thick, heavy rods buried deep into the earth around a protected structure. The conductor cables are connected to these rods to complete a safe path for a lightning discharge around a structure. They are vital as they disperse lightning current safely and effectively into the ground. Each down conductor must have a separate earth termination.
 |
| Earth Termination System |
If deep driving of earth rods cannot be achieved, a matrix arrangement of rods coupled to one another by conductors can be used spaced at a distance at least equal to their driven depth. If earth rods cannot be driven in a parallel line a "Crows Foot" configuration can be used, ensuring that the spacing/depth ratio is still maintained.
It is standard requirement that the system to be bonded to the building or structure grounding electrode system. This bonding connection is designed to minimize the difference of potential between the lightning protection system and the electrical system, which should reduce arcing/side flashing between metal parts within the building. All metal work, including water pipes, gas pipes, handrails, air conditioning units, metal cladding, metal roofs etc, in the vicinity of the
 |
| Equipotential bonding |
Lightning Protection System must be bonded to it, to avoid the danger of side flashing. For the same reason, the LPS earth should be bonded to the main electrical earth, as well as any other earthing system present in the structure.
(e) Surge arresters
This is a device that protects your equipment from over voltage transients caused by Lightning. Their installations should be well co-ordinated with the LPS ensure it offers the necessary protection to your equipment as well ensure continuity of its operation.
 |
| Installed Combined Lightning Current And Surge Arrester |
You should contact a qualified personnel to ascertain whether your structure actually needs a LPS after which he should go a head and design a system that suits your need and your structure.

Morocco`s Sahara Solar Power Plant
Morocco recently launched a massive solar power plant project to be done in phases namely Noor I, Noor II and Noor III with the first phase expected to be ready for use in the second half of 2016. Once complete this will be largest he single largest solar power production facility in the world as reported by The Guardian.
 |
| A Thermal Solar Power Plant |
The concentrated solar power plant, being the largest in the world, is expected to power over one million homes once complete in 2018. The solar plant uses concentrating solar power (CSP) which is more expensive to install than the widely used photovoltaic panels, but unlike them, enables the storage of energy for nights and cloudy days.
The project is being carried out by a Abu-Dhabi Renewables Developer, Marsdar confirms the delivery of the first phase of the plant by mid 2016. The company also reports that it has already installed roughly 9,000 of the 290-W systems, consisting of solar panels and batteries with sufficient storage capacity for three days along with energy-efficient appliances such as LED lamps and a 165-litre refrigerator.

What is a PBX/PABX?
Brief History Of PBX/PABX
A company with a manual switchboard was operated by a person plugging cables into sockets. This was known as a Private Manual Branch Exchange(PMBX). They were repalced by electromechanical and finally electronic switching systems(PABX).
 |
| ElectroMechanical Switchboard |
How Do PABX Work?
 |
| Components Of PABX System |
The outside lines (trunk lines) are available for making and receiving calls external to the site. Companies with more than one site can connect their PBXs together with trunk lines. PBX-like services can also be provided by equipment located off site at a central provider, delivering services over the public telephone network. This is known as a Private branch exchange Hosted PBX.
What Is The Future Of PBX?
Even though the a manual telephone operator who patched cables on a plug board was replaced, this system has continued to see improvements and developments throughout the years;
Hosted/ Virtual PABX systems is on the rise as a PABX system. This is when a large company, mostly telephone companies, offer PABX like services. After subscription, your telephone lines are connected to the service providers PABX system by internet. The only disadvantage is that your phones will not work without internet but you get rid off the need to install a PABX system.
