Paternity testing - How? Why? Where? Who?By: Ventura
All cells contain DNA. This includes the sex cells; sperm and egg cells. When a sperm and egg cell combine the new cell formed contains DNA from both parents. This single cell then divides on its way down the fallopian tube to the uterus. It implants into the uterus wall and grows into a foetus, and eventually a baby. If a couple have more than one child, they will each have different DNA, because the sperm and egg combine differently each time.
DNA analysis in a specialist laboratory can work out which parts came from the sperm (the father) and which from the egg (the mother). The results of this DNA analysis can be used as evidence about the likelihood of 2 individuals being related.
There is only a tiny chance of 2 individuals having identical DNA, unless they are identical twins. Identical twins will have the same DNA because the fertilized egg that split to give the 2 foetuses came from the same sperm and the same egg. It only split after the DNA from the two sex cells had already combined.
DNA analysis can be used to prove or disprove paternity. This is commonly used in cases where the mother is trying to claim maintenance payments from an absent father.
In cases of adoptees who are looking for their natural parents, DNA analysis is also being used.
Several companies have extensive DNA databases. These companies will analyse your DNA, look for a match and inform you discreetly of the results. The process is very simple; you pay your 50 dollars, you get a swab kit, you use the swab kit to wipe the inside of your cheek, you send off the swabs, the company analyses your DNA and sends you the results. They tell you if there is a match to any of the samples in their database. A
People can trace their relatives, including those in the country from which they emigrated.
Where paternity of a child is disputed, a DNA test can be used to convince a court to order a blood DNA test and make a maintenance order on the father. DNA tests are also used where there is a suspicion that the hospital has mixed up babies.
Your birth parents do not need to have registered to get a result. If ANY person related to you is in the database, a positive result will show. You may find grandparents, siblings or more distant relatives, all of which will lead to more information on your heritage.

Online Degrees - Points to watch out forBy: Ventura
Many reputable universities offer online degree courses. An online degree offers students many advantages, especially older students, who may have childcare commitments that need to be accommodated into a study regime. Given that students on a traditional course spend the greater part of their time partying, it is certainly possible to pack the study part of a university education into one or two years.
Employers are naturally suspicious of anything new in the way of qualifications, and there will be a certain reluctance, on the part of some, to accept an online degree as equivalent to a traditional one. This arises because of the wealth of worthless “life experience” degrees that can be obtained for $200 or less from universities that no-one has ever heard of.
An online degree from a traditional and respected university will get you over this hurdle. You should avoid lesser known universities offering these courses, even if they are accredited institutions. Employers do not have the resources to keep track of which institutions are reputable this year, and which were reputable in the year your degree was awarded. They will play safe and only interview candidates with qualifications from universities they recognize.
School principals and governors are some of the most conservative people on the planet. If you apply for a teaching job with a qualification from some unheard of university, they will assume your hard-earned qualification is an online degree and worthless.
If you are looking into an online education degree, then you need to be particularly careful that it includes some teaching experience in a school situation. Teachers want to be working alongside other teachers who have been through a similar system of training that they went through themselves.
The general perception amongst teachers is that online degree qualifications do not include teaching practice in the classroom. They want to know that you have some teaching experience in the classroom and to see reports relating to that.
These reports are the only relevant reference you have as far as most teachers are concerned. The extent of your knowledge, as measured by your degree is much less important than is your ability to communicate that knowledge to a group of students.

Creative Tips for Container Gardening
Creative Tips for Container Gardening
By: Paul Winter
Container gardens can create a natural sanctuary in a busy city street, along rooftops or on balconies. You can easily accentuate the welcoming look of a deck or patio with colorful pots of annuals, or fill your window boxes with beautiful shrub roses or any number of small perennials.
Whether you arrange your pots in a group for a massed effect or highlight a smaller space with a single specimen, you'll be delighted with this simple way to create a garden. Container gardening enables you to easily vary your color scheme, and as each plant finishes flowering, it can be replaced with another. Whether you choose to harmonize or contrast your colors, make sure there is variety in the height of each plant. Think also of the shape and texture of the leaves.
Tall strap-like leaves will give a good vertical background to low-growing, wide-leafed plants.
Choose plants with a long flowering season, or have others of a different type ready to replace them as they finish blooming. Experiment with creative containers. You might have an old porcelain bowl or copper urn you can use, or perhaps you'd rather make something really modern with timber or tiles. If you decide to buy your containers ready-made, terracotta pots look wonderful, but tend to absorb water. You don't want your plants to dry out, so paint the interior of these pots with a special sealer available from hardware stores.
Cheaper plastic pots can also be painted on the outside with water-based paints for good effect. When purchasing pots, don't forget to buy matching saucers to catch the drips. This will save cement floors getting stained, or timber floors rotting. Always use a good quality potting mix in your containers. This will ensure the best performance possible from your plants. If you have steps leading up to your front door, an attractive pot plant on each one will delight your visitors.
Indoors, pots of plants or flowers help to create a cozy and welcoming atmosphere. Decide ahead of time where you want your pots to be positioned, and then buy plants that suit the situation. There is no point buying sun lovers for a shady position, for they will not do well.
Some plants also have really large roots, so they are best kept for the open garden. If you have plenty of space at your front door, a group of potted plants off to one side will be more visually appealing than two similar plants placed each side. Unless they are spectacular, they will look rather boring.
Group the pots in odd numbers rather than even, and vary the height and type. To tie the group together, add large rocks that are similar in appearance and just slightly different in size. Three or five pots of the same type and color, but in different sizes also look affective. With a creative mind and some determination, you will soon have a container garden that will be the envy of friends and strangers alike.

The Science Behind the Dimples
The Science Behind The Dimples
By: Susan Chiang
The dynamics behind the flight of the golf ball offers a fascinating insight into the physical interworkings of air pressure, turbulence, and aerodynamics. When golf was first played in Scotland, most players played using clumsy golf apparatus, with the first golf clubs and golf balls made of wood.
In 1618 the “Featherie” was introduced. It was a golf ball made of feather. This feather golf ball was handcrafted from goose feathers tightly pressed into a horse or cowhide sphere while still wet. After drying, the leather shrank and the feathers expanded, creating a hardened golf ball.
As this type of golf ball was specially handcrafted, it was usually more expensive than golf clubs, so that only a few privileged people could afford to play golf back then.
After the Featherie golf ball came the Guttie golf ball. This type of golf ball was made from the rubber-like sap of the Gutta tree found in the tropics, and was shaped into a sphere when hot and eventually into a golf ball. As it was made of rubber, the Guttie golf ball could be cheaply produced and easily repaired by reheating and reshaping.
Comparing the two types of golf balls, the Featherie golf ball was said to travel farther than the Guttie golf ball because the Guttie golf ball’s smooth surface prevented it from covering more distance.
With this discovery, the developers of golf balls came up with the “dimpled” golf balls that are so predominant in modern golf nowadays.The dimples on the golf balls help reduce the aerodynamic drag. Aerodynamic drag normally affects smooth golf balls and slows them down, because when they sail through the air, they leave a pocket of low-pressure air in its stir thus creating a drag. By applying dimples to the golf ball surface, the pressure differential goes down and the drag force is reduced.
These dimples create turbulence in the air surrounding the golf ball, which, in turn, forces the air to clasp the golf ball more closely. By doing so, the air trails the warp created by the golf ball towards the back instead of flowing past it. This results in a smaller wake and lesser drag.
Dimples were first added onto golf ball surfaces back during the gutta percha phase. Coburn Haskell introduced the one-piece rubber cored golf ball encased in a gutta percha sphere. Then in 1905 William Taylor applied the dimple pattern to a Haskell golf ball, thus giving rise to the modern golf ball as we know it today.
After its beginning, dimpled golf balls were officially used in every golf tournament. In 1921, the golf ball took its current form with standard size and weight. Nowadays there is a wide range of golf balls to fit every style, game and condition, with some golf balls offering control, and other golf balls offering distance. Though a common sight nowadays, the dimpled golf ball is not just a mere element of the sports arena; it is a showcase of physics at work.
