It was one of those late nights and Maria was returning from work. She had had a hectic day and was dying to relax in the comfort of her new apartment. After taking a few winding turns, she realized that she was nowhere near home. But she did not panic. She had recently installed one of the new GPS units and that helped her reach home without much hassle.The above-mentioned scenario is not uncommon and could happen to anyone. In such situations, a GPS unit can come to your rescue. Whether you are going for a road trip to a distant place, have a bad sense of direction, are on a safari for hunting or just in an unfamiliar city, all you need is a GPS navigation unit as your friend and guide (pun intended!). For those of you who do not know what is a GPS, here is the answer.
The extended form of GPS is global positioning system. It was originally developed for the defense forces but now it is extensively used as a tracking system for cars and other objects. The GPS real time tracking system is satellite network based and gives the information related to the exact location or position of the objects on a real time basis.

How Does a Water Jet Cutter Work?
Water jet cutters may be still alien to many of us. To me it wasn't known until a few weeks ago, when a telly series on cutting metal and other substances amazed me. Along with high-end cutting machines with razor-sharp cutting technologies, it surprised me when they showed something as liquid as water being used to cut the hardest of substances. Now this is some technology and after this I truly believed in the capacities of engineering and the human mind. Using water pressure to cut substances, was roughly practiced during the mid 1800's. But the concrete concept of using water pressure as a cutting tool was discovered by Dr. Norman Franz, who was an engineer in forestry, in the year 1950. This was founded as an attempt to find new options to cut trees. He studied the technology of 'ultra high water pressure' (UHP) to be used as a cutting tool. Later to cut high-end solid substances, abrasives were added with the stream of water, which would let them cut even metals, with ease. With advancements today, the water jet cutter has been used in many sectors for cutting, drilling and milling. With water jet cutters being a revolutionary tool in the industrial sector, a little insight into its work mechanism will be interesting.
Salt Crystals - Recipe
Minerals are formed of tiny particles known as atoms. These atoms in most minerals have recurring pattern and follow a three-dimensional pattern. Due to this, a mineral has the ability to form in to a normal crystal with flat sides. Certain crystals have the ability to develop into cubes, while others develop into crystals with more than two sides. The latter is known as a prism.
Crystals can be easily grown at home using basic ingredients. Salt, sugar and alum crystals are often made at home. The basics for all of these materials remains same, where in you need to let the chemical dissolve in water and let the water evaporate or cool the solution which will automatically crystallize the substance. Before learning how to grow salt crystals using salt crystal recipes, let us look at some more information on salt crystals.
Branches of Science
Science is referred to as a system of objective knowledge obtained through deep researches done by the human being. Science is applied in every field and every aspect of life. With the help of scientific inventions and techniques, we have got all the latest facilities and high living standards. It's the science, with the help of which human being has reached beyond the space and stepped on the Moon and sent a spacecraft to Mars. There are a number of branches of science, out of which earth science, physical science and life science are the major branches. These three are considered as pure sciences. Other branches of science such as engineering, technology are associated with the practical application of result of scientific activity.
The physical science is associated with the nature and behavior of energy and matter. Physics includes the study of time, light and gravity. Chemistry deals with the properties, composition, structure and reactions of the matter. Astronomy involves the study of the universe beyond the earth. The earth science that involves the study of structure and composition of the earth includes different branches such as geology, oceanography, meteorology, paleontology, etc. Life science is also known as biology, which deals with the study of evolution, development, distribution, structure, origin and function of the living things. It is categorized into different branches such as botany, genetics, zoology, medicine, etc.

How to Become a Ball Boy/Girl in Tennis
Tennis is an amazing sport. You need great skill to be on the court in a Grand Slam. Not all of us have the expertise of a professional tennis player, but most of us dream to be a part of the action on the court, in a major event. Even if you lack the skills of a pro, you can make your dream come true by becoming a ball boy/girl. When you become a ball person you have the opportunity to be involved in a tennis match, you will be able to interact with the legends of the game, and if you observe keenly, you might also learn a few tricks to win a match.
How to Become a Ball Boy/Girl?
I have divided this section into 2 parts. The first part will tell you what you should have to become a good ball person, and the second part will tell you what you should do to become a ball boy/girl.
Essentials to Become a Ball Boy/Girl
Becoming a ball person is easy, if you have the following:
Love for the Game
If you do not love tennis, then you might get bored with your work after a few matches. You are not going to earn much, so when your job schedule turns out to be tiring, the only thing that will motivate you will be your love for the game of tennis. To become a successful ball boy/girl you should have a strong liking for the game, without it all your efforts to become a ball person are futile.

Dangers of Technology Addiction
The subject of technology addiction is relatively new as compared to drug or gambling addictions. This leads to a heated dispute over whether we need to consider the fervent need for technology and the monotony that the lack of technology causes, as an addiction. There are several qualifications that a craving needs to be termed as an addiction.
What Makes an Addiction?
The human state survival works on a simple reward system. Every time you attain a biological requirement like food, sex or lactation, the body releases a neurotransmitter called 'dopamine' (in this case, into the brain) that helps us decide the approach to something to be rewarded. This means the phase of wanting something and getting it, and the eventual liking of it is controlled by dopamine. It is this that fuels an addiction. Once you start using a piece of technology (like video games) and eventually start to like it, release of dopamine in the brain creates a reward system for it, which creates an addiction for it. The same example works for cigarettes - nicotine induces a dopamine release, creating the craving for more. An important point here is that people who seek more satisfaction from things, actually are seeking more in terms of dopamine release, and therefore require a larger release of the neurotransmitter, which in turn requires you to pursue that thing even more.

How Does a Rotary Phase Converter Work
A rotary phase converter may be defined as a device that helps an instrument or a technical equipment to run on a single-phase power. This device can be used to run original three phase equipment on a single phase power. To explain the dynamics of the same, a rotary phase converter produces a three-phase power from a single-phase power source. Thus, what the rotary phase converter does is to add a third source of power to the existing two power sources so that a three-phase power supply is generated.
Why You Must Use a Rotary Phase Converter
Rotary phase converters use a three-phase source of power with a power check correction factor, making the rotary-phase converter a safe and secure bet in providing energy. A rotary phase converter is made effective through equipping it with an efficient kick start capacity. The rotary phase converter can be employed at locations that do not have 3 phase service provided in the area. Electric companies may provide a 3-phase service, however the charges may not prove to be cost effective. The average cost may range anywhere between $30,000 to $90,000 to cover 1 mile with costs for internal wiring distribution costs. A rotary phase converter can thus, be considered an economical avenue as it does not require a 3-phase service set up to be installed. A single phase circuit installation is all that is required. It is very important that you consider the longevity factor before you purchase the rotary phase converter which provides for efficient start-up capabilities. It must also be equipped well to convert the single-phase power to three phase power sources. Before you decide on a rotary converter, check if the rotary phase converter is providing equal and well balanced power. If, however the power distribution is not even the equipment can sustain damage while working.
Types of Phase Converters
There are various types of phase converters. Digital phase converters and static phase converters are the other two types of converters apart from the rotary phase converter. The phase converters are suitable for various purposes. Static phase converters are used to give an efficient start up current to an engine whereas, rotary phase converters are employed to change single phase power to three phase power. This is not meant to deliver start up power to engines but is used in regulating large machinery. In this section we concentrate on the working of the rotary phase converter.

Types of Cell Division
Before we get to the part about the phenomenon or types of cell division, let's take a closer look at the two basic types of organic cellular structures that exist in this world as we know it. A cell can be either prokaryotic or eukaryotic, based upon its structural makeup. Prokaryotic cells have a simple, very basic structure as they neither have cell nuclei nor are they equipped with cellular organelles enclosed within membranes. In other words, all genetic matter and other areas partaking in various cellular functions and metabolic activities exist in free states within the cellular boundaries. Eukaryotic cells, on the other hand, are the more evolved, hi-tech counterparts of prokaryotic cells. They have all things that prokaryotic cells lack - cell nuclei holding all the genetic matter of the cells inside them, separate membrane bound organelles that have exclusive and specific tasks assigned to them (such as mitochondria, Golgi apparatus, chloroplasts, etc.), etc.
As you must have guessed by now, the more complex an organism is in terms of its physical structure and physiological functions, the more it is likely to have a eukaryotic cellular structure. This fact is evidenced by the fact the simplest of all life forms such as bacteria and archaea belong to the prokaryotic domain of biological classification. Now that the particulars of the two basic cellular structures have been discussed, let's move ahead to the next segment and take a look at what the various different types of cell division are.

How to Replace an ABS Wheel Speed Sensor
The Anti-lock Braking System (ABS) is one of the most significant parts in the safety package of an automobile. The main job of this technology is to prevent wheel lockup, at a time when momentary wheel rotation is actually needed for proper braking on slippery surfaces. The system functions using several components, out of which wheel speed sensors are one of the most prominent. It is the sensors that keep an eye on the speed of wheels and aid in releasing brake pressure during hard braking. The wheel speed is detected from the toothed wheel by the magnetic sensors, and sent to the ABS computer for brake and release action. If the ABS speed sensor goes bad, the braking will be a kind of irregular and abrupt when braking on low speeds. If you are considering this replacement as a DIY task, wear proper protective gear such as safety eye wear and gloves. Below is an explanation of how to replace an ABS wheel speed sensor.Since the sensors use battery power to function, replacing them firstly needs the battery connection to be disconnected. This can be done by disconnecting the negative terminal on the battery under the hood. Place wooden blocks or flat stones in front of every wheel to keep the car stable when doing this repair. In addition, also activate the parking brake. Lift the car using jacks and safety stands on the axle.As the ABS sensors are located behind the wheel assembly, you need to take out the wheel. Use a wrench and turn it counterclockwise on the lug nuts to remove the wheel off the hub. You might need to give a jerk to take the wheel off the assembly. The sensor would be a small black assembly on the hub. If you have just got the sensor changed and are experiencing ABS brake problems, a good idea is to clean the sensor. Clean the oil on the sensor and connectors with a cloth, fix the assembly correctly, and then see if the issue is resolved.
If you are sure about replacing ABS wheel speed sensor, you then need to take out the sensor's cable from the harness connector. The sensor would be joined to the hub by a small bolt which has to be removed. Ensure that you have the same sensor model like the old one to retain proper functioning of ABS. Take the new sensor and fix it on the appropriate place, by tightening the bolt on the assembly. Plug in the harness connector in the respective space on the new sensor.Make sure that there is no visible gap between the toothed wheel and sensor tip. However, the system works fine with a maximum of 0.04 inch gap between these two points. Reinstall the wheel assembly and tighten the nuts securely. Take the car off the jack stands slowly to rest on the ground. Do not forget to connect the negative terminal back on the battery, without which the ABS sensors won't work. During the replacement, you can even think about replacing the sensor cable as well. The total cost of the DIY project might come to around $50, just for the price of a new sensor and cable.Many a times, a simple cleanup of the sensor setup is more than enough to resolve ABS problems. For effective functioning of the system, do a periodical cleanup of the sensors on all wheels. The procedure for replacing ABS sensors on both front and rear axles is much the same as described in the above article. If you are not at all sure about the replacement, it is suggested to take professional help from an authorized service tech.
How to Make Algae Biofuel
The best way to go about understanding a how is to first get a good understanding of the what involved - that's one principle that I believe in and live by! Hence, before proceeding towards understanding how to make algae biofuel, let's take a closer look at what algae biofuel is all about. As the name suggests, this type of fuel is derived from algae and the method most commonly used is breaking down the alga's carbohydrate content via fermentation. This fermentation would result into biologically produced forms of the alcohols ethanol and butanol. Although it is gaining a lot of popularity these days as a potential alternative for traditional fossil fuels, this is so merely due to the fact that the doubled-edged sword of rapid depletion of traditional resources and ever increasing fossil fuel prices is hanging over the head of human civilization by a precariously thin thread.Other than that, algal fuel doesn't offer us much novelty value in terms of low polluting potential. You see, burning algal biofuel releases equally large amounts of carbon dioxide into the air as burning coal or petroleum based fuels do, as algae, being plant forms, need atmospheric carbon dioxide for photosynthesis. When you make fuel out of algae and burn it, this locked up carbon dioxide gets released into the atmosphere, undoing what algae did during its lifetime as a botanical life form. That being said, let's proceed towards finding out all about the algae biofuel extraction process.
Things We Can Do To Stop Global Warming
Global warming is caused due to the rising levels of carbon dioxide in the atmosphere that embraces the radiated heat and stores it, increasing the overall global temperatures to dangerous levels. The rising temperatures have caused the glaciers to melt, thus causing an increase in the sea level. Unpredictable weather and a strange change in climate patterns are also some of the effects of global warming. In fact, according to a recent study, over the past three decades our planet is said to be shrinking at a faster rate. Extreme climatic conditions like drought in some parts of the world while heavy rains in some others and record heat waves in most of the parts have send an alarming message to stop global warming. It is not that we are not trying to curb global warming; the governments of various countries and the UN (United Nations) have already started with their efforts to address the problem of global warming. They are doing their bit, and its time for us to address this sensitive problem on a personal level. Given below are a few things we can do to stop global warming.
Pros and Cons of Vegetable Oil as Fuel
As the issue of depletion of non-renewable sources is gaining momentum, researchers have started looking for other alternatives. There is a huge strain on gulf countries to produce oil in adequate quantities to satisfy the need of various countries of the world. Environmental concerns have also played an important part in establishing the need to look at other sources of energy, which are relatively less dangerous for the environmental health. Vegetable oil has emerged as strong contenders as an alternative fuel, however their use in commercial vehicles is still at an early stage.Vegetable oil can be used as an automobile fuel as there is a lot of waste that comes out from cooking and other agricultural products. Vegetable oils that are used as a fuel come under two categories - Straight Vegetable Oils (SVO) and Waste Vegetable Oils (WVO). As the name suggests, SVO is the oil that is available in the grocery stores and this oil can work in diesel engines after making some necessary modifications to the engine. WVO on the other hand, is the oil that has been used for cooking. The global food industry produces WVO in huge amounts, which when purified can be used as a fuel. There are numerous advantages of using vegetable oil as a fuel but there are some challenges involved before it can be used in automobiles on a large scale. Let us take a look at the pros and cons of vegetable oil as fuel.
