Background We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind. Volta’s pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications.
The electronics, computers and communications industries, power engineering and much of the chemical industry of today were founded on discoveries made possible by the battery. Pioneers It is often overlooked that throughout the nineteenth century, most of the electrical experimenters, inventors and engineers who made these advances possible had to make their own batteries before they could start their investigations.
They did not have the benefit of cheap, off the shelf, mass produced batteries. For many years the telegraph, and later the telephone, industries were the only consumers of batteries in modest volumes and it wasn’t until the twentieth century that new applications created the demand that made the battery a commodity item.
In recent years batteries have changed out of all recognition. No longer are they simple electrochemical cells. Today the cells are components in battery systems, incorporating electronics and software, power management and control systems, monitoring and protection circuits, communications interfaces and thermal management.

Antenatal tests can be done to detect genetic or chromosomal abnormalities. There are two types of tests: Diagnostic tests are ultrasound scan, nuchal scan, AFP test, maternal serum triple test, Chorionic Villus sampling and amniocentesis. Antenatal testing has become available at several centres. It is important to realise that any antenatal test can lead to a confrontation with an unexpected abnormal result. This may lead to difficult decisions regarding the option of pregnancy termination, a decision some parents may feel they do not want to face.
Thus, for many women, the decision to have the tests is a difficult one because of the serious implications of the information provided. Many families are not always sure that having the tests is the right decision for them as they may be bound by moral, ethical or religious issues. For this reason no antenatal tests should be performed without in-depth discussion with, and informed consent from the parents.
